Quick Example

example.component.ts:

import { Component, OnInit} from '@angular/core';
import { SimpleUploadService, SimpleUploadParams } from 'angular-upload-files';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example].component.css']
})
export class ExampleComponent implements OnInit {

  SimpleUploadParams : SimpleUploadParams;
  progress: string;
  fileCount: number;
  files: any[];

  constructor(private SimpleUploadService : SimpleUploadService) {}

  ngOnInit() {
    this.SimpleUploadParams = {
      formDataPropertyName: 'image', 
      extraParams: [{
        paramValueIsFromFile: true,
        paramValue: "name",
        paramName: "filename"
      }]
    }
    this.SimpleUploadService.currentUploadProgress.subscribe(
      (progress)=>{
        console.log(progress);
        this.progress = progress;
      }
    )
  }
  readFiles(event) {
    console.log(event, event.files, event.base64s); //read files from here, and if using images base64s also
    this.fileCount = event.files.length;

    // you can manipulate the files here, or just store them
    this.files = event.files;
  }
  uploadDone(event) {
    console.log(event);
    this.fileCount--;

    if(this.fileCount === 0) {
      //files are COMPLETELY done uploading
    }
  }
}

example.component.html

<app-uploader
(onFilesSelected)="readFiles($event)"
(onUploadComplete)="uploadDone($event)"
[buttonText]="'Choose File'"
[buttonClass]="'btn btn-default'"
[postUrl]="'https://api.imgur.com/3/image'"
[id]="0"
[multiple]="true"
[SimpleUploadParams]="SimpleUploadParams"
></app-uploader>

<p>{{progress}}% uploaded</p>

App Module Setup:

import {SimpleUploaderModule} from 'angular-upload-files'; 

@NgModule({
  declarations: [
    AppComponent,
  ],
  imports: [
    BrowserModule,
    FormsModule,
    SimpleUploaderModule.forRoot(), // <---------------
    HttpClientModule,
    RouterModule.forRoot(Routes) 
  ],
  providers: [
  ],
  bootstrap: [AppComponent],
}) 

In your component:

import { SimpleUploadService, SimpleUploadParams } from 'angular-upload-files';

constructor(private SimpleUploadService : SimpleUploadService) { }

Interfaces:

export interface SimpleUploadParams {
  formDataPropertyName: string;
  extraParams : ExtraParams[];
}
export interface ExtraParams {
  paramValueIsFromFile: boolean;
  paramName: string;
  paramValue: any;
}

You must input a SimpleUploadParams object into each instance of the uploader: formDataPropertyName: string; The uploader will automatically append a FormData object with the file and file name attached, as well as the formDataPropertyName (this is how it looks internally):

formData.append(this.SimpleUploadParams.formDataPropertyName, file, file.name);

Extra Params:

Extra Params is for passing query string parameters to your request:

example:

    this.SimpleUploadParams = {formDataPropertyName: 'image', extraParams: {
      paramValueIsFromFile: true, //paramValue will be accessed as file[paramValue] set false for value to be just paramValue
      paramValue: "name",
      paramName: "filename"
    }}

    this.SimpleUploadParams = {formDataPropertyName: 'image', extraParams: {
      paramValueIsFromFile: false, //paramValue will be accessed as paramValue (params.set(paramName, paramValue))
      paramValue: "name",
      paramName: "filename"
    }}

Inputs:

Events:

Triggering events from your component:

Triggering events from your component: (MULTIPLE UPLOADERS)

NOTE: You may omit the componentId but all uploaders will receive the sent event if you do so.

Upload Progress:

this.SimpleUploadService.currentUploadProgress.subscribe(
    (progress)=>{
        console.log(progress);
    }
)
