# ngx-uploader Angular 2+ File Uploader http://ngx-uploader.com #### Got a Question or Problem? Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on [Stack Overflow](https://stackoverflow.com) where the questions should be tagged with tag `ngx-uploader`. To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow. ## Installation 1. Add `ngx-uploader` module as dependency to your project. ```console npm install ngx-uploader --save ``` 2. Include `NgxUploaderModule` into your main AppModule or in module where you will use it. ```ts // app.module.ts import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { NgxUploaderModule } from 'ngx-uploader'; @NgModule({ imports: [BrowserModule, NgxUploaderModule], declarations: [AppComponent] }) export class AppModule {} ``` **or** include `NgxUploaderModule` into your SharedModule. This could be usefull if your project has nested Modules. ```ts // shared.module.ts import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { NgxUploaderModule } from 'ngx-uploader'; ... @NgModule({ imports: [ CommonModule, NgxUploaderModule, ... ], exports: [ CommonModule, NgxUploaderModule, ... ], ... }) export class SharedModule { } ``` ```ts // app.module.ts import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { SharedModule } from './shared.module'; @NgModule({ imports: [BrowserModule, SharedModule], declarations: [AppComponent] }) export class AppModule {} ``` ## Data Structures of Events and Uploaded Files ```ts export interface UploaderOptions { concurrency: number; // number of files uploaded at the same time allowedContentTypes?: string[]; // content types allowed (default *) maxUploads?: number; // max number of files the user can upload maxFileSize?: number; // max size of the file in bytes the user can upload } export interface UploadProgress { status: UploadStatus; // current status of upload for specific file (Queue | Uploading | Done | Canceled) data?: { percentage: number; // percentage of upload already completed speed: number; // current upload speed per second in bytes speedHuman: string; // current upload speed per second in human readable form, eta: number; // estimated time remaining in seconds etaHuman: string; // estimated time remaining in human readable format }; } export interface UploadFile { id: string; // unique id of uploaded file instance fileIndex: number; // fileIndex in internal ngx-uploader array of files lastModifiedDate: Date; // last modify date of the file (Date object) name: string; // original name of the file size: number; // size of the file in bytes type: string; // mime type of the file form: FormData; // FormData object (you can append extra data per file, to this object) progress: UploadProgress; response?: any; // response when upload is done (parsed JSON or string) responseStatus?: number; // response status code when upload is done responseHeaders?: { [key: string]: string }; // response headers when upload is done } // output events emitted by ngx-uploader export interface UploadOutput { type: | 'addedToQueue' | 'allAddedToQueue' | 'uploading' | 'done' | 'removed' | 'start' | 'cancelled' | 'dragOver' | 'dragOut' | 'drop'; file?: UploadFile; nativeFile?: File; // native javascript File object, can be used to process uploaded files in other libraries } // input events that user can emit to ngx-uploader export interface UploadInput { type: 'uploadAll' | 'uploadFile' | 'cancel' | 'cancelAll' | 'remove' | 'removeAll'; url?: string; // URL to upload file to method?: string; // method (POST | PUT) id?: string; // unique id of uploaded file fieldName?: string; // field name (default 'file') fileIndex?: number; // fileIndex in internal ngx-uploader array of files file?: UploadFile; // uploading file data?: { [key: string]: string | Blob }; // custom data sent with the file headers?: { [key: string]: string }; // custom headers includeWebKitFormBoundary?: boolean; // If false, only the file is send trough xhr.send (WebKitFormBoundary is omit) concurrency?: number; // concurrency of how many files can be uploaded in parallel (default is 0 which means unlimited) withCredentials?: boolean; // apply withCredentials option } ``` ## Upload Restrictions With version 4.2.1 we've introduced restrictions for Content-Types. To not break the behaviour of previous releases, there are no restrictions by default at all. Look at [app-home.component.ts](https://github.com/bleenco/ngx-uploader/blob/master/src/components/app-home/app-home.component.ts) for an example of Content-Type restriction. If you want to toast a message for the rejected file, add this to your onUploadOutput method. ```ts onUploadOutput(output: UploadOutput): void { .... } else if (output.type === 'rejected' && typeof output.file !== 'undefined') { // console.log(output.file.name + ' rejected'); } ... ``` ## Token Authorization If you have to upload files with Token Authorization, you can set the header in startUpload as follows. ```ts startUpload(): void { let token = this.myToken; // <---- get token const event: UploadInput = { type: 'uploadAll', url: 'http://ngx-uploader.com/upload', method: 'POST', headers: { 'Authorization': 'JWT ' + token }, // <---- set headers data: { foo: 'bar' }, includeWebKitFormBoundary: true // <---- set WebKitFormBoundary }; this.uploadInput.emit(event); } ``` ## Example **You can always run working example by cloning this repository, building project with `yarn build:prod` and running server with `node ./dist-app/api/index.js`.** ### Component Code ```ts import { Component, EventEmitter } from '@angular/core'; import { UploadOutput, UploadInput, UploadFile, humanizeBytes, UploaderOptions } from 'ngx-uploader'; @Component({ selector: 'app-home', templateUrl: 'app-home.component.html' }) export class AppHomeComponent { options: UploaderOptions; formData: FormData; files: UploadFile[]; uploadInput: EventEmitter; humanizeBytes: Function; dragOver: boolean; constructor() { this.options = { concurrency: 1, maxUploads: 3, maxFileSize: 1000000 }; this.files = []; // local uploading files array this.uploadInput = new EventEmitter(); // input events, we use this to emit data to ngx-uploader this.humanizeBytes = humanizeBytes; } onUploadOutput(output: UploadOutput): void { switch (output.type) { case 'allAddedToQueue': // uncomment this if you want to auto upload files when added // const event: UploadInput = { // type: 'uploadAll', // url: '/upload', // method: 'POST', // data: { foo: 'bar' } // }; // this.uploadInput.emit(event); break; case 'addedToQueue': if (typeof output.file !== 'undefined') { this.files.push(output.file); } break; case 'uploading': if (typeof output.file !== 'undefined') { // update current data in files array for uploading file const index = this.files.findIndex(file => typeof output.file !== 'undefined' && file.id === output.file.id); this.files[index] = output.file; } break; case 'removed': // remove file from array when removed this.files = this.files.filter((file: UploadFile) => file !== output.file); break; case 'dragOver': this.dragOver = true; break; case 'dragOut': case 'drop': this.dragOver = false; break; case 'done': // The file is downloaded break; } } startUpload(): void { const event: UploadInput = { type: 'uploadAll', url: 'http://ngx-uploader.com/upload', method: 'POST', data: { foo: 'bar' } }; this.uploadInput.emit(event); } cancelUpload(id: string): void { this.uploadInput.emit({ type: 'cancel', id: id }); } removeFile(id: string): void { this.uploadInput.emit({ type: 'remove', id: id }); } removeAllFiles(): void { this.uploadInput.emit({ type: 'removeAll' }); } } ``` ### Template Code For whole template code please check [here](https://github.com/bleenco/ngx-uploader/blob/master/src/components/app-home/app-home.component.html). ```html
