What is Contentful?
Contentful provides content infrastructure for digital teams to power websites, apps, and devices. Unlike a CMS, Contentful was built to integrate with the modern software stack. It offers a central hub for structured content, powerful management and delivery APIs, and a customizable web app that enable developers and content creators to ship their products faster.

Pre-requisites && Installation

Pre-requisites

  • Node LTS

Installation

npm install contentful-migration

Usage

:exclamation: Usage as CLI

We moved the CLI version of this tool into our Contentful CLI. This allows our users to use and install only one single CLI tool to get the full Contentful experience.
Please have a look at the Contentful CLI migration command documentation to learn more about how to use this as command line tool.

Usage as a library

const { runMigration } = require('contentful-migration')
const options = {
  filePath: '<migration-file-path>',
  spaceId: '<space-id>',
  accessToken: '<access-token>'
}
runMigration(options)
  .then(() => console.log('Migration Done!'))
  .catch((e) => console.error(e))

In your migration description file, export a function that accepts the migration object as its argument. For example:
module.exports = function (migration, context) {
  const dog = migration.createContentType('dog')
  const name = dog.createField('name')
  name.type('Symbol').required(true)
}

You can also pass the function directly. For example:
const { runMigration } = require('contentful-migration')

function migrationFunction(migration, context) {
  const dog = migration.createContentType('dog')
  const name = dog.createField('name')
  name.type('Symbol').required(true)
}

const options = {
  migrationFunction,
  spaceId: '<space-id>',
  accessToken: '<access-token>'
}

runMigration(options)
  .then(() => console.log('Migration Done!'))
  .catch((e) => console.error(e))

Chaining vs Object notation

All methods described below can be used in two flavors:
  1. The chained approach:
```javascript
const author = migration
  .createContentType('author')
  .name('Author')
  .description('Author of blog posts or pages')
```
  1. The object approach:
```javascript
const author = migration.createContentType('author', {
  name: 'Author',
  description: 'Author of blog posts or pages'
})
```

While both approaches work, **it is recommended to use the chained approach** since validation errors will display context information whenever an error is detected, along with a line number. The object notation will lead the validation error to only show the line where the object is described, whereas the chained notation will show precisely where the error is located.

migration

The main interface for creating and editing content types and tags.

createContentType(id[, opts]) : ContentType

Creates a content type with provided id and returns a reference to the newly created content type.
id : string – The ID of the content type.
opts : Object – Content type definition, with the following options:
  • name : string – Name of the content type.
  • description : string – Description of the content type.
  • displayField : string – ID of the field to use as the display field for the content type. This is referred to as the "Entry title" in the web application.

editContentType(id[, opts]) : ContentType

Edits an existing content type of provided id and returns a reference to the content type. Uses the same options as createContentType.

deleteContentType(id)

Deletes the content type with the provided id and returns undefined. Note that the content type must not have any entries.

transformEntries(config)

For the given content type, transforms all its entries according to the user-provided transformEntryForLocale function. For each entry, the CLI will call this function once per locale in the space, passing in the from fields and the locale as arguments. The transform function is expected to return an object with the desired target fields. If it returns undefined, this entry locale will be left untouched.
config : Object – Content transformation definition, with the following properties:
  • contentType : string (required) – Content type ID
  • from : array (required) – Array of the source field IDs
  • to : array (required) – Array of the target field IDs
  • transformEntryForLocale : function (fields, locale, {id}): object (required) – Transformation function to be applied.
- fields is an object containing each of the from fields. Each field will contain their current localized values (i.e. fields == {myField: {'en-US': 'my field value'}}) - locale one of the locales in the space being transformed - id id of the current entry in scope
The return value must be an object with the same keys as specified in `to`. Their values will be written to the respective entry fields for the current locale (i.e. `{nameField: 'myNewValue'}`). If it returns `undefined`, this the values for this locale on the entry will be left untouched.
  • shouldPublish : bool | 'preserve' (optional) – Flag that specifies publishing of target entries, preserve will keep current states of the source entries (default 'preserve')
transformEntries Example
migration.transformEntries({
  contentType: 'newsArticle',
  from: ['author', 'authorCity'],
  to: ['byline'],
  transformEntryForLocale: function (fromFields, currentLocale, { id }) {
    if (currentLocale === 'de-DE') {
      return
    }
    const newByline = `${fromFields.author[currentLocale]} ${fromFields.authorCity[currentLocale]}`
    return { byline: newByline }
  }
})

For the complete version, please refer to this example.

deriveLinkedEntries(config)

For each entry of the given content type (source entry), derives a new entry and sets up a reference to it on the source entry. The content of the new entry is generated by the user-provided deriveEntryForLocale function. For each source entry, this function will be called as many times as there are locales in the space. Each time, it will be called with the from fields and one of the locales as arguments. The derive function is expected to return an object with the desired target fields. If it returns undefined, the new entry will have no values for the current locale.
config : Object – Entry derivation definition, with the following properties:
  • contentType : string (required) – Source content type ID

  • derivedContentType : string (required) – Target content type ID

  • from : array (required) – Array of the source field IDs

  • toReferenceField : string (required) – ID of the field on the source content type in which to insert the reference

  • derivedFields : array (required) – Array of the field IDs on the target content type

  • identityKey: function (fields): string (required) - Called once per source entry. Returns the ID used for the derived entry, which is also used for de-duplication so that multiple source entries can link to the same derived entry.

- fields is an object containing each of the from fields. Each field will contain their current localized values (i.e. fields == {myField: {'en-US': 'my field value'}})
  • deriveEntryForLocale : function (fields, locale, {id}): object (required) – Function that generates the field values for the derived entry.

- fields is an object containing each of the from fields. Each field will contain their current localized values (i.e. fields == {myField: {'en-US': 'my field value'}}) - locale one of the locales in the space being transformed - id id of the current entry in scope
The return value must be an object with the same keys as specified in derivedFields. Their values will be written to the respective new entry fields for the current locale (i.e. {nameField: 'myNewValue'})
  • shouldPublish : bool|'preserve' (optional) – If true, both the source and the derived entries will be published. If false, both will remain in draft state. If preserve, will keep current states of the source entries (default true)
deriveLinkedEntries(config) Example
migration.deriveLinkedEntries({
  contentType: 'dog',
  derivedContentType: 'owner',
  from: ['owner'],
  toReferenceField: 'ownerRef',
  derivedFields: ['firstName', 'lastName'],
  identityKey: async (fromFields) => {
    return fromFields.owner['en-US'].toLowerCase().replace(' ', '-')
  },
  shouldPublish: true,
  deriveEntryForLocale: async (inputFields, locale, { id }) => {
    if (locale !== 'en-US') {
      return
    }
    const [firstName, lastName] = inputFields.owner[locale].split(' ')
    return {
      firstName,
      lastName
    }
  }
})

For the complete version of this migration, please refer to this example.

transformEntriesToType(config)

For the given (source) content type, transforms all its entries according to the user-provided transformEntryForLocale function into a new entry of a specific different (target) content type. For each entry, the CLI will call the function transformEntryForLocale once per locale in the space, passing in the from fields and the locale as arguments. The transform function is expected to return an object with the desired target fields. If it returns undefined, this entry locale will be left untouched.
config : Object – Content transformation definition, with the following properties:
  • sourceContentType : string (required) – Content type ID of source entries
  • targetContentType : string (required) – Targeted Content type ID
  • from : array (optional) – Array of the source field IDs, returns complete list of fields if not configured
  • identityKey: function (fields): string (required) - Function to create a new entry ID for the target entry
  • shouldPublish : bool | 'preserve' (optional) – Flag that specifies publishing of target entries, preserve will keep current states of the source entries (default false)
  • updateReferences : bool (optional) – Flag that specifies if linking entries should be updated with target entries (default false). Note that this flag does not support Rich Text Fields references.
  • removeOldEntries : bool (optional) – Flag that specifies if source entries should be deleted (default false)
  • transformEntryForLocale : function (fields, locale, {id}): object (required) – Transformation function to be applied.

- fields is an object containing each of the from fields. Each field will contain their current localized values (i.e. fields == {myField: {'en-US': 'my field value'}}) - locale one of the locales in the space being transformed - id id of the current entry in scope
The return value must be an object with the same keys as specified in the targetContentType. Their values will be written to the respective entry fields for the current locale (i.e. {nameField: 'myNewValue'}). If it returns undefined, the values for this locale on the entry will be left untouched.
transformEntriesToType Example
const MurmurHash3 = require('imurmurhash')

migration.transformEntriesToType({
  sourceContentType: 'dog',
  targetContentType: 'copycat',
  from: ['woofs'],
  shouldPublish: false,
  updateReferences: false,
  removeOldEntries: false,
  identityKey: function (fields) {
    const value = fields.woofs['en-US'].toString()
    return MurmurHash3(value).result().toString()
  },
  transformEntryForLocale: function (fromFields, currentLocale, { id }) {
    return {
      woofs: `copy - ${fromFields.woofs[currentLocale]}`
    }
  }
})

For the complete version of this migration, please refer to this example.

createTag(id[, opts, visibility])

Creates a tag with provided id and returns a reference to the newly created tag.
  • id : string – The ID of the tag.

  • opts : Object – Tag definition, with the following options:

- name : string – Name of the tag.
  • visibility : 'private' | 'public' Tag visibility - defaults to private.

editTag(id[, opts])

Edits an existing tag of provided id and returns a reference to the tag. Uses the same options as createTag.

deleteTag(id)

Deletes the tag with the provided id and returns undefined. Note that this deletes the tag even if it is still attached to entries or assets.

setTagsForEntries(config)

For the given content type, updates the tags that are attached to its entries according to the user-provided setTagsForEntry function. For each entry, the CLI will call this function once, passing in the from fields, link objects of all tags that already are attached to the entry and link objects of all tags available in the environment. The setTagsForEntry function is expected to return an array with link objects for all tags that are to be added to the entry. If it returns undefined, the entry will be left untouched.
config : Object – Content transformation definition, with the following properties:
  • contentType : string (required) – Content type ID
  • from : array (required) – Array of the source field IDs
  • setTagsForEntry : function (entryFields, entryTags, apiTags): array (required) – Transformation function to be applied. - entryFields is an object containing each of the from fields. - entryTags is an array containing link objects of all tags
already attached to the entry. - apiTags is an array containing link objects of all tags available in the environment.
setTagsForEntries Example
migration.createTag('department-sf').name('Department: San Francisco')
migration.createTag('department-ldn').name('Department: London')

const departmentMapping = {
  'san-francisco': 'department-sf',
  london: 'department-ldn'
}

migration.setTagsForEntries({
  contentType: 'news-article',
  from: ['department'],
  setTagsForEntry: (entryFields, entryTags, apiTags) => {
    const departmentField = entryFields.department['en-US']
    const newTag = apiTags.find((tag) => tag.sys.id === departmentMapping[departmentField])

    return [...entryTags, newTag]
  }
})

context

There may be cases where you want to use Contentful API features that are not supported by the migration object. For these cases you have access to the internal configuration of the running migration in a context object.
module.exports = async function (migration, { makeRequest, spaceId, accessToken }) {
  const contentType = await makeRequest({
    method: 'GET',
    url: `/content_types?sys.id[in]=foo`
  })

  const anyOtherTool = new AnyOtherTool({ spaceId, accessToken })
}

makeRequest(config)

config : Object - Configuration for the request based on the Contentful management SDK
  • method : string – HTTP method
  • url : string - HTTP endpoint

module.exports = async function (migration, { makeRequest }) {
  const contentType = await makeRequest({
    method: 'GET',
    url: `/content_types?sys.id[in]=foo`
  })
}

spaceId : string

The space ID that was set for the current migration.

accessToken : string

The access token that was set for the current migration.

Example migrations

You can check out the examples to learn more about the migrations DSL. Each example file is prefixed with a sequence number, specifying the order in which you're supposed to run the migrations, as follows:
const runMigration = require('contentful-migration/built/bin/cli').runMigration

const options = {
  spaceId: '<space-id>',
  accessToken: '<access-token>',
  yes: true
}

const migrations = async () => {
  await runMigration({ ...options, ...{ filePath: '01-angry-dog.js' } })
  await runMigration({ ...options, ...{ filePath: '02-friendly-dog.js' } })
  await runMigration({ ...options, ...{ filePath: '03-long-example.js' } })
  await runMigration({ ...options, ...{ filePath: '04-steps-errors.js' } })
  await runMigration({ ...options, ...{ filePath: '05-plan-errors.js' } })
  await runMigration({ ...options, ...{ filePath: '06-delete-field.js' } })
  await runMigration({ ...options, ...{ filePath: '07-display-field.js' } })
}

Writing Migrations in Typescript

You can use Typescript to write your migration files using ts-node! First npm install --save ts-node typescript, then run your migration with ts-node:
node_modules/.bin/ts-node node_modules/.bin/contentful-migration -s $CONTENTFUL_SPACE_ID -a $CONTENTFUL_MANAGEMENT_TOKEN my_migration.ts

An example Typescript migration:
import { MigrationFunction } from 'contentful-migration'

// typecast to 'MigrationFunction' to ensure you get type hints in your editor
export = function (migration, { makeRequest, spaceId, accessToken }) {
  const dog = migration.createContentType('dog', {
    name: 'Dog'
  })

  const name = dog.createField('name')
  name.name('Name').type('Symbol').required(true)
} as MigrationFunction

Here's how it looks inside VS Code:

Troubleshooting

  • Unable to connect to Contentful through your Proxy? Try to set the rawProxy option to true.

runMigration({
  proxy: 'https://cat:dog@example.com:1234',
  rawProxy: true,
  ...
})

Updating Integration tests fixtures

  • To add new/update integration tests, you need to set environment variable NOCK_RECORD=1 which should automatically update fixtures
