Works in modern browsers, as well as runtimes like [Node.js], [Bun], [Deno], and [Edge Runtime] ## QuickStart Install the client with a package manager: ```sh npm install @sanity/client ``` Import and create a new client instance, and use its methods to interact with your project's [Content Lake]. Below are some simple examples in plain JavaScript. Read further for more comprehensive documentation. ```js // sanity.js import {createClient} from '@sanity/client' // Import using ESM URL imports in environments that supports it: // import {createClient} from 'https://esm.sh/@sanity/client' export const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version // token: process.env.SANITY_SECRET_TOKEN // Only if you want to update content with the client }) // uses GROQ to query content: https://www.sanity.io/docs/groq export async function getPosts() { const posts = await client.fetch('*[_type == "post"]') return posts } export async function createPost(post: Post) { const result = client.create(post) return result } export async function updateDocumentTitle(_id, title) { const result = client.patch(_id).set({title}) return result } ``` # Table of contents - [QuickStart](#quickstart) - [Requirements](#requirements) - [Installation](#installation) - [API](#api) - [Creating a client instance](#creating-a-client-instance) - [ESM](#esm) - [CommonJS](#commonjs) - [TypeScript](#typescript) - [Next.js App Router](#nextjs-app-router) - [Bun](#bun) - [Deno](#deno) - [Edge Runtime](#edge-runtime) - [Browser ESM CDN](#browser-esm-cdn) - [UMD](#umd) - [Specifying API version](#specifying-api-version) - [Request tags](#request-tags) - [Performing queries](#performing-queries) - [Using perspectives](#using-perspectives) - [`published`](#published) - [`previewDrafts`](#previewdrafts) - [Fetching Content Source Maps](#fetching-content-source-maps) - [Using Visual editing with steganography](#using-visual-editing-with-steganography) - [Creating Studio edit intent links](#creating-studio-edit-intent-links) - [Listening to queries](#listening-to-queries) - [Fetch a single document](#fetch-a-single-document) - [Fetch multiple documents in one go](#fetch-multiple-documents-in-one-go) - [Creating documents](#creating-documents) - [Creating/replacing documents](#creatingreplacing-documents) - [Creating if not already present](#creating-if-not-already-present) - [Patch/update a document](#patchupdate-a-document) - [Setting a field only if not already present](#setting-a-field-only-if-not-already-present) - [Removing/unsetting fields](#removingunsetting-fields) - [Incrementing/decrementing numbers](#incrementingdecrementing-numbers) - [Patch a document only if revision matches](#patch-a-document-only-if-revision-matches) - [Adding elements to an array](#adding-elements-to-an-array) - [Appending/prepending elements to an array](#appendingprepending-elements-to-an-array) - [Deleting an element from an array](#deleting-an-element-from-an-array) - [Delete documents](#delete-documents) - [Multiple mutations in a transaction](#multiple-mutations-in-a-transaction) - [Clientless patches \& transactions](#clientless-patches--transactions) - [Uploading assets](#uploading-assets) - [Examples: Uploading assets from Node.js](#examples-uploading-assets-from-nodejs) - [Examples: Uploading assets from the Browser](#examples-uploading-assets-from-the-browser) - [Examples: Specify image metadata to extract](#examples-specify-image-metadata-to-extract) - [Deleting an asset](#deleting-an-asset) - [Mutation options](#mutation-options) - [Aborting a request](#aborting-a-request) - [1.

The JavaScript runtime must support ES6 features such as [class](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes), [rest parameters](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/rest_parameters), [spread syntax](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax) and more. Most modern web frameworks, [browsers][modern browsers], and developer tooling supports ES6 today. [For legacy ES5 environments we recommend v4.](https://github.com/sanity-io/client/tree/v4.0.0#sanityclient) ## Installation The client can be installed from [npm]: ```sh npm install @sanity/client # Alternative package managers yarn add @sanity/client pnpm install @sanity/client ``` ## API ### Creating a client instance `const client = createClient(options)` Initializes a new Sanity Client. Required options are `projectId`, `dataset`, and `apiVersion`. [We encourage setting `useCdn` to either `true` or `false`.](https://www.sanity.io/help/js-client-cdn-configuration) The default is `true`. If you're not sure which option to choose we recommend starting with `true` and revise later if you find that you require uncached content. [Our awesome Slack community can help guide you on how to avoid stale data tailored to your tech stack and architecture.](https://slack.sanity.io/) #### [ESM](https://hacks.mozilla.org/2018/03/es-modules-a-cartoon-deep-dive/) ```js import {createClient} from '@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const data = await client.fetch(`count(*)`) console.log(`Number of documents: ${data}`) ``` #### [CommonJS] ```js const {createClient} = require('@sanity/client') const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) client .fetch(`count(*)`) .then((data) => console.log(`Number of documents: ${data}`)) .catch(console.error) ``` #### [TypeScript] ```ts import {createClient, type ClientConfig} from '@sanity/client' const config: ClientConfig = { projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version } const client = createClient(config) const data = await client.fetch(`count(*)`) // data is typed as `number` console.log(`Number of documents: ${data}`) ``` We're currently exploring typed GROQ queries that are runtime safe, and will share more when we've landed on a solution we're satisifed with. Until then you can achieve this using [Zod]: ```ts import {createClient} from '@sanity/client' import {z} from 'zod' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const schema = z.number() const data = schema.parse(await client.fetch(`count(*)`)) // data is guaranteed to be `number`, or zod will throw an error console.log(`Number of documents: ${data}`) ``` Another alternative is [groqd]. #### [Next.js App Router](https://nextjs.org/docs/app/building-your-application/data-fetching/fetching-caching-and-revalidating#fetching-data-on-the-server-with-fetch) ```tsx import {createClient} from '@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) export default async function ReactServerComponent() { const data = await client.fetch( `count(*[_type == "page"])`, {}, { // You can set any of the `cache` and `next` options as you would on a standard `fetch` call cache: 'force-cache', next: {tags: ['pages']}, }, ) return

Number of pages: {data}

} ``` The `cache` and `next` options are documented in the [Next.js documentation](https://nextjs.org/docs/app/api-reference/functions/fetch#fetchurl-options). Since [request memoization](https://nextjs.org/docs/app/building-your-application/caching#request-memoization) is supported it's unnecessary to use [the `React.cache`](https://nextjs.org/docs/app/building-your-application/caching#react-cache-function) API. To [opt-out of memoization](https://nextjs.org/docs/app/building-your-application/caching#opting-out), set the `signal` property: ```tsx const {signal} = new AbortController() // By passing `signal` this request will not be memoized and `now()` will execute for every React Server Component that runs this query const data = await client.fetch(`{"dynamic": now()}`, {}, {signal}) ``` #### [Bun] ```bash bun init bun add @sanity/client open index.ts ``` ```ts // index.ts import {createClient} from '@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const data = await client.fetch(`count(*)`) console.write(`Number of documents: ${data}`) ``` ```bash bun run index.ts # Number of documents ${number} ``` #### [Deno] ```bash deno init open main.ts ``` ```ts // main.ts import {createClient} from 'https://esm.sh/@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const data = await client.fetch(`count(*)`) console.log(`Number of documents: ${data}`) ``` ```bash deno run --allow-net --allow-env main.ts # Number of documents ${number} ``` #### [Edge Runtime] ```bash npm install next ``` ```ts // pages/api/total.ts import {createClient} from '@sanity/client' import type {NextRequest} from 'next/server' export const config = { runtime: 'edge', } export default async function handler(req: NextRequest) { const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const count = await client.fetch(`count(*)`) return new Response(JSON.stringify({count}), { status: 200, headers: { 'content-type': 'application/json', }, }) } ``` ```bash npx next dev # Open http://localhost:3000/api/total # {"count": number} ``` #### Browser ESM CDN Using [esm.sh] you can either load the client using a `

``` Or from anywhere using a dynamic `import()`: ```js // You can run this snippet from your browser DevTools console. // Super handy when you're quickly testing out queries. const {createClient} = await import('https://esm.sh/@sanity/client') const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2023-05-03', // use current date (YYYY-MM-DD) to target the latest API version }) const data = await client.fetch(`count(*)`) console.log(`Number of documents: ${data}`) ``` #### [UMD][unpkg-dist] Loading the UMD script creates a `SanityClient` global that have the same exports as `import * as SanityClient from '@sanity/client'`: ```html ``` The `require-unpkg` library lets you consume `npm` packages from `unpkg.com` similar to how `esm.sh` lets you `import()` anything: ```html

``` ### Specifying API version Sanity uses ISO dates (YYYY-MM-DD) in UTC timezone for versioning. The explanation for this can be found [in the documentation][api-versioning] In general, unless you know what API version you want to use, you'll want to statically set it to today's UTC date when starting a new project. By doing this, you'll get all the latest bugfixes and features, while locking the API to prevent breaking changes. **Note**: Do not be tempted to use a dynamic value for the `apiVersion`. The reason for setting a static value is to prevent unexpected, breaking changes. In future versions, specifying an API version will be required. For now (to maintain backwards compatiblity) not specifying a version will trigger a deprecation warning and fall back to using `v1`. ### Request tags Request tags are values assigned to API and CDN requests that can be used to filter and aggregate log data within [request logs][request-logs] from your Sanity Content Lake. Sanity Client has out-of-the-box support for tagging every API and CDN request on two levels: - Globally: Using the `requestTagPrefix` client configuration parameter - Per Request: Pass the tag option to the SDK’s Request method. The following example will result in a query with `tag=website.landing-page`: ```ts const client = createClient({ projectId: '', dataset: '', useCdn: true, apiVersion: '2024-01-24', requestTagPrefix: 'website', // Added to every request }) const posts = await client.fetch('*[_type == "post"]', { tag: `index-page`, // Appended to requestTagPrefix for this individual request }) ``` ### Performing queries ```js const query = '*[_type == "bike" && seats >= $minSeats] {name, seats}' const params = {minSeats: 2} client.fetch(query, params).then((bikes) => { console.log('Bikes with more than one seat:') bikes.forEach((bike) => { console.log(`${bike.name} (${bike.seats} seats)`) }) }) ``` `client.fetch(query, params = {})` Perform a query using the given parameters (if any). ### Using perspectives The `perspective` option can be used to specify special filtering behavior for queries. The default value is `raw`, which means no special filtering is applied, while [`published`](#published) and [`previewDrafts`](#previewdrafts) can be used to optimize for specific use cases. #### `published` Useful for when you want to be sure that draft documents are not returned in production. Pairs well with private datasets. With a dataset that looks like this: ```json [ { "_type": "author", "_id": "ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George Martin" }, { "_type": "author", "_id": "drafts.ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George R.R. Martin" }, { "_type": "author", "_id": "drafts.f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "name": "Stephen King" } ] ``` And a query like this: ```ts import {createClient} from '@sanity/client' const client = createClient({ ...config, useCdn: true, // set to `false` to bypass the edge cache perspective: 'published', }) const authors = await client.fetch('*[_type == "author"]') ``` Then `authors` will only contain documents that don't have a `drafts.` prefix in their `_id`, in this case just "George Martin": ```json [ { "_type": "author", "_id": "ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George Martin" } ] ``` #### `previewDrafts` Designed to help answer the question "What is our app going to look like after all the draft documents are published?". Given a dataset like this: ```json [ { "_type": "author", "_id": "ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George Martin" }, { "_type": "author", "_id": "drafts.ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George R.R. Martin" }, { "_type": "author", "_id": "drafts.f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "name": "Stephen King" }, { "_type": "author", "_id": "6b3792d2-a9e8-4c79-9982-c7e89f2d1e75", "name": "Terry Pratchett" } ] ``` And a query like this: ```ts import {createClient} from '@sanity/client' const client = createClient({ ...config, useCdn: false, // the `previewDrafts` perspective requires this to be `false` perspective: 'previewDrafts', }) const authors = await client.fetch('*[_type == "author"]') ``` Then `authors` will look like this. Note that the result dedupes documents with a preference for the draft version: ```json [ { "_type": "author", "_id": "ecfef291-60f0-4609-bbfc-263d11a48c43", "_originalId": "drafts.ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George R.R. Martin" }, { "_type": "author", "_id": "f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "_originalId": "drafts.f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "name": "Stephen King" }, { "_type": "author", "_id": "6b3792d2-a9e8-4c79-9982-c7e89f2d1e75", "_originalId": "6b3792d2-a9e8-4c79-9982-c7e89f2d1e75", "name": "Terry Pratchett" } ] ``` Since the query simulates what the result will be after publishing the drafts, the `_id` doesn't contain the `drafts.` prefix. If you want to check if a document is a draft or not you can use the `_originalId` field, which is only available when using the `previewDrafts` perspective. ```ts const authors = await client.fetch(`*[_type == "author"]{..., "status": select( _originalId in path("drafts.**") => "draft", "published" )}`) ``` Which changes the result to be: ```json [ { "_type": "author", "_id": "ecfef291-60f0-4609-bbfc-263d11a48c43", "_originalId": "drafts.ecfef291-60f0-4609-bbfc-263d11a48c43", "name": "George R.R. Martin", "status": "draft" }, { "_type": "author", "_id": "f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "_originalId": "f4898efe-92c4-4dc0-9c8c-f7480aef17e2", "name": "Stephen King", "status": "published" } ] ``` ### Fetching Content Source Maps Content Source Maps annotate fragments in your query results with metadata about its origin: the field, document, and dataset it originated from. > [!IMPORTANT] > > Content Source Maps are supported in the Content Lake API versions `2021-03-25` and later. Before diving in, review the [Content Source Maps introduction][content-source-maps-intro] and keep the [Content Source Maps reference][content-source-maps] within reach for a quick lookup. Enabling Content Source Maps is a two-step process: 1. Update your client configuration with `resultSourceMap`. ```js import {createClient} from '@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', useCdn: true, // set to `false` to bypass the edge cache apiVersion: '2021-03-25', // use current date (YYYY-MM-DD) to target the latest API version resultSourceMap: true, // tells the API to start sending source maps, if available }) ``` 2. On `client.fetch` calls add `{filterResponse: false}` to return the full response on queries. ```js // Before // const result = await client.fetch(query, params) // After adding `filterResponse: false` const {result, resultSourceMap} = await client.fetch(query, params, {filterResponse: false}) // Build something cool with the source map console.log(resultSourceMap) ``` If your `apiVersion` is `2021-03-25` or later, the `resultSourceMap` property will always exist in the response after enabling it. If there is no source map, `resultSourceMap` is an empty object. This is the corresponding TypeScript definition: ```ts import type {ContentSourceMapping} from '@sanity/client' const {result, resultSourceMap} = await client.fetch(query, params, {filterResponse: false}) function useContentSourceMap(resultSourceMap: ContentSourceMapping): unknown { // Sky's the limit } useContentSourceMap(resultSourceMap) ``` #### Using [Visual editing][visual-editing] with steganography A turnkey integration with [Visual editing][visual-editing] is available in [`@sanity/client`], with additional utils available on [`@sanity/client/stega`]. It creates edit intent links for all the string values in your query result, using [steganography](https://npmjs.com/package/@vercel/stega) under the hood. The code that handles stega is lazy loaded on demand when `client.fetch` is called, if `client.config().stega.enabled` is `true`. ```ts import {createClient} from '@sanity/client' const client = createClient({ // ...base config options stega: { // If you use Vercel Visual Editing, we recommend enabling it for Preview deployments enabled: process.env.VERCEL_ENV === 'preview', // Required: Set it to the relative or absolute URL of your Sanity Studio instance studioUrl: '/studio', // or 'https://your-project-name.sanity.studio' // To resolve Cross Dataset References, pass a function returning a URL studioUrl: (sourceDocument: ContentSourceMapDocument | ContentSourceMapRemoteDocument) => { // If `sourceDocument` has a projectId and a dataset, then it's a Cross Dataset Reference if (source._projectId && source._dataset) { return 'https://acme-global.sanity.studio' } return 'https://acme-store.sanity.studio' }, // If your Studio has Workspaces: https://www.sanity.io/docs/workspaces // and if your Cross Dataset References are available in a workspace, you can return an object to let the client set up the URL studioUrl: (sourceDocument) => { // This organization has a single studio with everything organized in workspaces const baseUrl = 'https://acme.sanity.studio' // If `sourceDocument` has a projectId and a dataset, then it's a Cross Dataset Reference if (source._projectId && source._dataset) { return {baseUrl, workspace: 'global'} } return {baseUrl, workspace: 'store'} }, // Optional, to control which fields have stega payloads filter: (props) => { const {resultPath, sourcePath, sourceDocument, value} = props if (sourcePath[0] === 'externalurl') { return false } // The default behavior is packaged into `filterDefault`, allowing you to enable encoding fields that are skipped by default return props.filterDefault(props) }, // Optional, to log what's encoded and what isn't // logger: console, }, }) // Disable on demand client.config({stega: {enabled: false}}) // New client with different stega settings const debugClient = client.withConfig({ stega: {studioUrl: 'https://your-project-name.sanity.studio', logger: console}, }) ``` Removing stega from part of the result, available on [`@sanity/client/stega`]: ```ts import {stegaClean} from '@sanity/client/stega' const result = await client.fetch('*[_type == "video"][0]') // Remove stega from the payload sent to a third party library const videoAsset = stegaClean(result.videoAsset) ``` #### Creating Studio edit intent links If you want to create an edit link to something that isn't a string, or a field that isn't rendered directly, like a `slug` used in a URL but not rendered on the page, you can use the `resolveEditUrl` function. ```ts import {createClient} from '@sanity/client' import {resolveEditUrl} from '@sanity/client/csm' const client = createClient({ // ... standard client config // Required: the new 'withKeyArraySelector' option is used here instead of 'true' so that links to array items and portable text are stable even if the array is reordered resultSourceMap: 'withKeyArraySelector', }) const {result, resultSourceMap} = await client.fetch( `*[_type == "author" && slug.current == $slug][0]{name, pictures}`, {slug: 'john-doe'}, // Required, otherwise you can't access `resultSourceMap` {filterResponse: false}, ) // The `result` looks like this: const result = { name: 'John Doe', pictures: [ { _type: 'image', alt: 'A picture of exactly what you think someone named John Doe would look like', _key: 'cee5fbb69da2', asset: { _ref: 'image-a75b03fdd5b5fa36947bf2b776a542e0c940f682-1000x1500-jpg', _type: 'reference', }, }, ], } const studioUrl = 'https://your-project-name.sanity.studio' resolveEditUrl({ // The URL resolver requires the base URL of your Sanity Studio instance studioUrl, // It also requires a Content Source Map for the query result you want to create an edit intent link for resultSourceMap, // The path to the field you want to edit. You can pass a string resultPath: 'pictures[0].alt', // or an array of segments resultPath: ['pictures', 0, 'alt'], }) // ^? 'https://your-project-name.sanity.studio/intent/edit/mode=presentation;id=462efcc6-3c8b-47c6-8474-5544e1a4acde;type=author;path=pictures[_key=="cee5fbb69da2"].alt' ``` ### Listening to queries ```js const query = '*[_type == "comment" && authorId != $ownerId]' const params = {ownerId: 'bikeOwnerUserId'} const subscription = client.listen(query, params).subscribe((update) => { const comment = update.result console.log(`${comment.author} commented: ${comment.text}`) }) // to unsubscribe later on subscription.unsubscribe() ``` `client.listen(query, params = {}, options = {includeResult: true})` Open a query that listens for updates on matched documents, using the given parameters (if any). The return value is an [RxJS Observable](https://rxjs.dev/guide/observable). When calling `.subscribe()` on the returned observable, a [subscription](https://rxjs.dev/api/index/class/Subscription) is returned, and this can be used to unsubscribe from the query later on by calling `subscription.unsubscribe()` The update events which are emitted always contain `mutation`, which is an object containing the mutation which triggered the document to appear as part of the query. By default, the emitted update event will also contain a `result` property, which contains the document with the mutation applied to it. In case of a delete mutation, this property will not be present, however. You can also tell the client not to return the document (to save bandwidth, or in cases where the mutation or the document ID is the only relevant factor) by setting the `includeResult` property to `false` in the options. Likewise, you can also have the client return the document _before_ the mutation was applied, by setting `includePreviousRevision` to `true` in the options, which will include a `previous` property in each emitted object. ### Fetch a single document This will fetch a document from the [Doc endpoint](https://www.sanity.io/docs/http-doc). This endpoint cuts through any caching/indexing middleware that may involve delayed processing. As it is less scalable/performant than the other query mechanisms, it should be used sparingly. Performing a query is usually a better option. ```js client.getDocument('bike-123').then((bike) => { console.log(`${bike.name} (${bike.seats} seats)`) }) ``` ### Fetch multiple documents in one go This will fetch multiple documents in one request from the [Doc endpoint](https://www.sanity.io/docs/http-doc). This endpoint cuts through any caching/indexing middleware that may involve delayed processing. As it is less scalable/performant than the other query mechanisms, it should be used sparingly. Performing a query is usually a better option. ```js client.getDocuments(['bike123', 'bike345']).then(([bike123, bike345]) => { console.log(`Bike 123: ${bike123.name} (${bike123.seats} seats)`) console.log(`Bike 345: ${bike345.name} (${bike345.seats} seats)`) }) ``` Note: Unlike in the HTTP API, the order/position of documents is _preserved_ based on the original array of IDs. If any of the documents are missing, they will be replaced by a `null` entry in the returned array: ```js const ids = ['bike123', 'nonexistent-document', 'bike345'] client.getDocuments(ids).then((docs) => { // the docs array will be: // [{_id: 'bike123', ...}, null, {_id: 'bike345', ...}] }) ``` ### Creating documents ```js const doc = { _type: 'bike', name: 'Sanity Tandem Extraordinaire', seats: 2, } client.create(doc).then((res) => { console.log(`Bike was created, document ID is ${res._id}`) }) ``` `client.create(doc)` `client.create(doc, mutationOptions)` Create a document. Argument is a plain JS object representing the document. It must contain a `_type` attribute. It _may_ contain an `_id`. If an ID is not specified, it will automatically be created. To create a draft document, prefix the document ID with `drafts.` - eg `_id: 'drafts.myDocumentId'`. To auto-generate a draft document ID, set `_id` to `drafts.` (nothing after the `.`). ### Creating/replacing documents ```js const doc = { _id: 'my-bike', _type: 'bike', name: 'Sanity Tandem Extraordinaire', seats: 2, } client.createOrReplace(doc).then((res) => { console.log(`Bike was created, document ID is ${res._id}`) }) ``` `client.createOrReplace(doc)` `client.createOrReplace(doc, mutationOptions)` If you are not sure whether or not a document exists but want to overwrite it if it does, you can use the `createOrReplace()` method. When using this method, the document must contain an `_id` attribute. ### Creating if not already present ```js const doc = { _id: 'my-bike', _type: 'bike', name: 'Sanity Tandem Extraordinaire', seats: 2, } client.createIfNotExists(doc).then((res) => { console.log('Bike was created (or was already present)') }) ``` `client.createIfNotExists(doc)` `client.createIfNotExists(doc, mutationOptions)` If you want to create a document if it does not already exist, but fall back without error if it does, you can use the `createIfNotExists()` method. When using this method, the document must contain an `_id` attribute. ### Patch/update a document ```js client .patch('bike-123') // Document ID to patch .set({inStock: false}) // Shallow merge .inc({numSold: 1}) // Increment field by count .commit() // Perform the patch and return a promise .then((updatedBike) => { console.log('Hurray, the bike is updated! New document:') console.log(updatedBike) }) .catch((err) => { console.error('Oh no, the update failed: ', err.message) }) ``` Modify a document. `patch` takes a document ID. `set` merges the partialDoc with the stored document. `inc` increments the given field with the given numeric value. `commit` executes the given `patch`. Returns the updated object. ``` client.patch() [operations] .commit(mutationOptions) ``` ### Setting a field only if not already present ```js client.patch('bike-123').setIfMissing({title: 'Untitled bike'}).commit() ``` ### Removing/unsetting fields ```js client.patch('bike-123').unset(['title', 'price']).commit() ``` ### Incrementing/decrementing numbers ```js client .patch('bike-123') .inc({price: 88, numSales: 1}) // Increment `price` by 88, `numSales` by 1 .dec({inStock: 1}) // Decrement `inStock` by 1 .commit() ``` ### Patch a document only if revision matches You can use the `ifRevisionId(rev)` method to specify that you only want the patch to be applied if the stored document matches a given revision. ```js client .patch('bike-123') .ifRevisionId('previously-known-revision') .set({title: 'Little Red Tricycle'}) .commit() ``` ### Adding elements to an array The patch operation `insert` takes a location (`before`, `after` or `replace`), a path selector and an array of elements to insert. ```js client .patch('bike-123') // Ensure that the `reviews` arrays exists before attempting to add items to it .setIfMissing({reviews: []}) // Add the items after the last item in the array (append) .insert('after', 'reviews[-1]', [{title: 'Great bike!', stars: 5}]) .commit({ // Adds a `_key` attribute to array items, unique within the array, to // ensure it can be addressed uniquely in a real-time collaboration context autoGenerateArrayKeys: true, }) ``` ### Appending/prepending elements to an array The operations of appending and prepending to an array are so common that they have been given their own methods for better readability: ```js client .patch('bike-123') .setIfMissing({reviews: []}) .append('reviews', [{title: 'Great bike!', stars: 5}]) .commit({autoGenerateArrayKeys: true}) ``` ### Deleting an element from an array Each entry in the `unset` array can be either an attribute or a JSON path. In this example, we remove the first review and the review with `_key: 'abc123'` from the `bike.reviews` array: ```js const reviewsToRemove = ['reviews[0]', 'reviews[_key=="abc123"]'] client.patch('bike-123').unset(reviewsToRemove).commit() ``` ### Delete documents A single document can be deleted by specifying a document ID: `client.delete(docId)` `client.delete(docId, mutationOptions)` ```js client .delete('bike-123') .then(() => { console.log('Bike deleted') }) .catch((err) => { console.error('Delete failed: ', err.message) }) ``` One or more documents can be deleted by specifying a GROQ query (and optionally, `params`): `client.delete({ query: "GROQ query", params: { key: value } })` ```js // Without params client .delete({query: '*[_type == "bike"][0]'}) .then(() => { console.log('The document matching *[_type == "bike"][0] was deleted') }) .catch((err) => { console.error('Delete failed: ', err.message) }) ``` ```js // With params client .delete({query: '*[_type == $type][0..1]', params: {type: 'bike'}}) .then(() => { console.log('The documents matching *[_type == "bike"][0..1] was deleted') }) .catch((err) => { console.error('Delete failed: ', err.message) }) ``` ### Multiple mutations in a transaction ```js const namePatch = client.patch('bike-310').set({name: 'A Bike To Go'}) client .transaction() .create({name: 'Sanity Tandem Extraordinaire', seats: 2}) .delete('bike-123') .patch(namePatch) .commit() .then((res) => { console.log('Whole lot of stuff just happened') }) .catch((err) => { console.error('Transaction failed: ', err.message) }) ``` `client.transaction().create(doc).delete(docId).patch(patch).commit()` Create a transaction to perform chained mutations. ```js client .transaction() .create({name: 'Sanity Tandem Extraordinaire', seats: 2}) .patch('bike-123', (p) => p.set({inStock: false})) .commit() .then((res) => { console.log('Bike created and a different bike is updated') }) .catch((err) => { console.error('Transaction failed: ', err.message) }) ``` `client.transaction().create(doc).patch(docId, p => p.set(partialDoc)).commit()` A `patch` can be performed inline on a `transaction`. ### Clientless patches & transactions Transactions and patches can also be built outside the scope of a client: ```js import {createClient, Patch, Transaction} from '@sanity/client' const client = createClient({ projectId: 'your-project-id', dataset: 'bikeshop', }) // Patches: const patch = new Patch('') client.mutate(patch.inc({count: 1}).unset(['visits'])) // Transactions: const transaction = new Transaction().create({_id: '123', name: 'FooBike'}).delete('someDocId') client.mutate(transaction) ``` `const patch = new Patch(docId)` `const transaction = new Transaction()` An important note on this approach is that you cannot call `commit()` on transactions or patches instantiated this way, instead you have to pass them to `client.mutate()` ### Uploading assets Assets can be uploaded using the `client.assets.upload(...)` method. ``` client.assets.upload(type: 'file' | image', body: File | Blob | Buffer | NodeJS.ReadableStream, options = {}): Promise ``` 👉 Read more about [assets in Sanity](https://sanity.io/docs/assets) #### Examples: Uploading assets from Node.js ```js // Upload a file from the file system client.assets .upload('file', fs.createReadStream('myFile.txt'), {filename: 'myFile.txt'}) .then((document) => { console.log('The file was uploaded!', document) }) .catch((error) => { console.error('Upload failed:', error.message) }) ``` ```js // Upload an image file from the file system client.assets .upload('image', fs.createReadStream('myImage.jpg'), {filename: 'myImage.jpg'}) .then((document) => { console.log('The image was uploaded!', document) }) .catch((error) => { console.error('Upload failed:', error.message) }) ``` #### Examples: Uploading assets from the Browser ```js // Create a file with "foo" as its content const file = new File(['foo'], 'foo.txt', {type: 'text/plain'}) // Upload it client.assets .upload('file', file) .then((document) => { console.log('The file was uploaded!', document) }) .catch((error) => { console.error('Upload failed:', error.message) }) ``` ```js // Draw something on a canvas and upload as image const canvas = document.getElementById('someCanvas') const ctx = canvas.getContext('2d') ctx.fillStyle = '#f85040' ctx.fillRect(0, 0, 50, 50) ctx.fillStyle = '#fff' ctx.font = '10px monospace' ctx.fillText('Sanity', 8, 30) canvas.toBlob(uploadImageBlob, 'image/png') function uploadImageBlob(blob) { client.assets .upload('image', blob, {contentType: 'image/png', filename: 'someText.png'}) .then((document) => { console.log('The image was uploaded!', document) }) .catch((error) => { console.error('Upload failed:', error.message) }) } ``` #### Examples: Specify image metadata to extract ```js // Extract palette of colors as well as GPS location from exif client.assets .upload('image', someFile, {extract: ['palette', 'location']}) .then((document) => { console.log('The file was uploaded!', document) }) .catch((error) => { console.error('Upload failed:', error.message) }) ``` ### Deleting an asset Deleting an asset document will also trigger deletion of the actual asset. ``` client.delete(assetDocumentId: string): Promise ``` ```js client.delete('image-abc123_someAssetId-500x500-png').then((result) => { console.log('deleted imageAsset', result) }) ``` ### Mutation options The following options are available for mutations, and can be applied either as the second argument to `create()`, `createOrReplace`, `createIfNotExists`, `delete()` and `mutate()` - or as an argument to the `commit()` method on patches and transactions. - `visibility` (`'sync'|'async'|'deferred'`) - default `'sync'` - `sync`: request will not return until the requested changes are visible to subsequent queries. - `async`: request will return immediately when the changes have been committed, but it might still be a second or more until changes are reflected in a query. Unless you are immediately re-querying for something that includes the mutated data, this is the preferred choice. - `deferred`: fastest way to write - bypasses real-time indexing completely, and should be used in cases where you are bulk importing/mutating a large number of documents and don't need to see that data in a query for tens of seconds. - `dryRun` (`true|false`) - default `false`. If true, the mutation will be a dry run - the response will be identical to the one returned had this property been omitted or false (including error responses) but no documents will be affected. - `autoGenerateArrayKeys` (`true|false`) - default `false`. If true, the mutation API will automatically add `_key` attributes to objects in arrays that is missing them. This makes array operations more robust by having a unique key within the array available for selections, which helps prevent race conditions in real-time, collaborative editing. ### Aborting a request Requests can be aborted (or cancelled) in two ways: #### 1. Abort a request by passing an [AbortSignal] with the request options Sanity Client supports the [AbortController] API and supports receiving an abort signal that can be used to cancel the request. Here's an example that will abort the request if it takes more than 200ms to complete: ```js const abortController = new AbortController() // note the lack of await here const request = getClient().fetch('*[_type == "movie"]', {}, {signal: abortController.signal}) // this will abort the request after 200ms setTimeout(() => abortController.abort(), 200) try { const response = await request //… } catch (error) { if (error.name === 'AbortError') { console.log('Request was aborted') } else { // rethrow in case of other errors throw error } } ``` #### 2. Cancel a request by unsubscribing from the Observable When using the Observable API (e.g. `client.observable.fetch()`), you can cancel the request by simply `unsubscribe` from the returned observable: ```js const subscription = client.observable.fetch('*[_type == "movie"]').subscribe((result) => { /* do something with the result */ }) // this will cancel the request subscription.unsubscribe() ``` ### Get client configuration ```js const config = client.config() console.log(config.dataset) ``` `client.config()` Get client configuration. ### Set client configuration ```js client.config({dataset: 'newDataset'}) ``` `client.config(options)` Set client configuration. Required options are `projectId` and `dataset`. ## License MIT © [Sanity.io](https://www.sanity.io/) # Migrate ## From `v5` ### The default `useCdn` is changed to `true` It was previously `false`. If you were relying on the default being `false` you can continue using the live API by setting it in the constructor: ```diff import {createClient} from '@sanity/client' export const client = createClient({ projectId: 'your-project-id', dataset: 'your-dataset-name', apiVersion: '2023-03-12', + useCdn: false, // set to `true` to use the edge cache }) ``` ## From `v4` ### No longer shipping `ES5` The target is changed to [modern browsers] that supports `ES6` `class`, `{...rest}` syntax and more. You may need to update your bundler to a recent major version. Or you could configure your bundler to transpile `@sanity/client`, and `get-it`, which is the engine that powers `@sanity/client` and uses the same output target. ### Node.js `v12` no longer supported
