Installation

Install via NPM:

Or via YARN:

Initialization

Add the UploaderModule to your app:

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { UploaderModule } from "angular-uploader";

import { AppComponent } from "./app.component";

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule, 
    UploaderModule // <-- Add the Uploader module here.
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

Components & Directives

Choose one of these options:

Option 1: Create an Upload Button — Try on StackBlitz

The uploadButton directive displays a file upload modal on click.

Inputs:

uploader (required): an instance of the Uploader class.
uploadOptions (optional): an object following the UploadWidgetConfig interface.
uploadComplete (optional): a callback containing a single parameter — an array of uploaded files.

import { Component } from '@angular/core';
import { Uploader, UploadWidgetConfig, UploadWidgetResult } from 'uploader';

@Component({
  selector: 'app-root',
  template: `
    <a href="{{ uploadedFileUrl }}" target="_blank">{{ uploadedFileUrl }}</a>
    <button
      uploadButton
      [uploadComplete]="onComplete"
      [uploadOptions]="options"
      [uploader]="uploader"
    >
      Upload a file...
    </button>
  `,
})
export class AppComponent {
  uploader = Uploader({
    apiKey: 'free', // <-- Get production-ready API keys from Upload.io
  });
  options: UploadWidgetConfig = {
    multi: false,
  };
  onComplete = (files: UploadWidgetResult[]) => {
    this.uploadedFileUrl = files[0]?.fileUrl;
  };
  uploadedFileUrl = undefined;
}

Option 2: Create a Dropzone — Try on StackBlitz

The upload-dropzone component renders an inline drag-and-drop file uploader.

Inputs:

uploader (required): an instance of the Uploader class.
options (optional): an object following the UploadWidgetConfig interface.
onComplete (optional): a callback containing the array of uploaded files as its parameter.
onUpdate (optional): same as above, but called after every file upload or removal.
width (optional): width of the dropzone.
height (optional): height of the dropzone.

import { Component } from "@angular/core";
import { Uploader, UploadWidgetConfig, UploadWidgetResult } from "uploader";

@Component({
  selector: "app-root",
  template: `
    <upload-dropzone [uploader]="uploader" 
                     [options]="options"
                     [onUpdate]="onUpdate"
                     [width]="width"
                     [height]="height"> 
    </upload-dropzone>
  `
})
export class AppComponent {
  uploader = Uploader({ 
    apiKey: "free" 
  });
  options: UploadWidgetConfig = {
    multi: false
  };
  // 'onUpdate' vs 'onComplete' attrs on 'upload-dropzone':
  // - Dropzones are non-terminal by default (they don't have an end
  //   state), so by default we use 'onUpdate' instead of 'onComplete'.
  // - To create a terminal dropzone, use the 'onComplete' attribute
  //   instead and add the 'showFinishButton: true' option.
  onUpdate = (files: UploadWidgetResult[]) => {
    alert(files.map(x => x.fileUrl).join("\n"));
  };
  width = "600px";
  height = "375px";
}

The Result

The callbacks receive a Array<UploadWidgetResult>:

{
  fileUrl: "https://upcdn.io/FW25...",   // URL to use when serving this file.
  filePath: "/uploads/example.jpg",      // File path (we recommend saving this to your database).
    
  editedFile: undefined,                 // Edited file (for image crops). Same structure as below.

  originalFile: {
    fileUrl: "https://upcdn.io/FW25...", // Uploaded file URL.
    filePath: "/uploads/example.jpg",    // Uploaded file path (relative to your raw file directory).
    accountId: "FW251aX",                // Upload.io account the file was uploaded to.
    originalFileName: "example.jpg",     // Original file name from the user's machine.
    file: { ... },                       // Original DOM file object from the <input> element.
    size: 12345,                         // File size in bytes.
    lastModified: 1663410542397,         // Epoch timestamp of when the file was uploaded or updated.
    mime: "image/jpeg",                  // File MIME type.
    metadata: {
      ...                                // User-provided JSON object.
    },
    tags: [
      "tag1",                            // User-provided & auto-generated tags.
      "tag2",
      ...
    ]
  }
}

Angular Uploader is a wrapper for Uploader — see the Uploader Docs 📖

Where are my files stored?

Uploader uses Upload.io as a file storage & file hosting backend.

Upload.io benefits developers with:

Zero Setup (Start uploading in the next few minutes!)
Pre-Integrated Storage (All you need is an Upload API key)
Fast File Hosting (Worldwide CDN, 300 Nodes)
Powerful Rules Engine (Rate Limiting, Traffic Limiting, IP Blacklisting, Expiring Links, etc)
File Transformations (Image Resizing, Cropping, Optimization, etc)

🔧 Can I bring my own file storage?

Yes! Upload.io supports custom S3 buckets.

You still need an Upload.io account to use the widget.
