Angular 2+ File Uploader (this includes also Angular 5)
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 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.
We are actively maintain the 4.x branch. The 2.x and 3.x are outdated and you should NOT use this branches any more. Therefore all open issues for that releases will be closed soon.
This module has been completely rewritten from scratch with the version 3.0.0.
If you are looking for documentation for version prior to 3.0.0, please check 2.x.x branch.
- Add
ngx-uploadermodule as dependency to your project.
npm install ngx-uploader --save
- Include
NgUploaderModuleinto your main AppModule or in module where you will use it.
// app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgUploaderModule } from 'ngx-uploader';
@NgModule({
imports: [
BrowserModule,
NgUploaderModule
],
declarations: [ AppComponent ],
exports: [ AppComponent ]
})
export class AppModule {}
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
concurrency?: number; // concurrency of how many files can be uploaded in parallel (default is 0 which means unlimited)
withCredentials?: boolean; // apply withCredentials option
}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 for an example of Content-Type restriction.
If you want to toast a message for the rejected file, add this to your onUploadOutput method.
onUploadOutput(output: UploadOutput): void {
....
} else if (output.type === 'rejected' && typeof output.file !== 'undefined') {
// console.log(output.file.name + ' rejected');
}
...If you have to upload files with Token Authorization, you can set the header in startUpload as follows.
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' }
};
this.uploadInput.emit(event);
}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.
import { Component, EventEmitter } from '@angular/core';
import { UploadOutput, UploadInput, UploadFile, humanizeBytes, UploaderOptions } from 'ngx-uploader';

uploadInput: EventEmitter<UploadInput>;
humanizeBytes: Function;
dragOver: boolean;
constructor() {
this.files = []; // local uploading files array
this.uploadInput = new EventEmitter<UploadInput>(); // input events, we use this to emit data to ngx-uploader
this.humanizeBytes = humanizeBytes;
}
onUploadOutput(output: UploadOutput): void {
if (output.type === 'allAddedToQueue') { // when all files added in queue
// 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);
} else if (output.type === 'addedToQueue' && typeof output.file !== 'undefined') { // add file to array when added
this.files.push(output.file);
} else if (output.type === 'uploading' && 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;
} else if (output.type === 'removed') {
// remove file from array when removed
this.files = this.files.filter((file: UploadFile) => file !== output.file);
} else if (output.type === 'dragOver') {
this.dragOver = true;
} else if (output.type === 'dragOut') {
