Angular PrimeNG FileUpload Auto Uploads

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will see how to use the FileUpload Auto Uploads in Angular PrimeNG.

Angular PrimeNG FileUpload Auto Uploads are used to enable automatic upload, i.e. the file upload begins as soon as file selection is completed or a file is dropped on the drop area when the auto property is enabled.

Syntax:

<p-fileUpload name="..."
                url="..."
                 [auto]="true">
</p-fileUpload>

Creating Angular application & Module Installation:

Step 1: Create an Angular application using the following command.

ng new appname

Step 2: After creating your project folder i.e. appname, move to it using the following command.

cd appname

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: It will look like the following:

Example 1: Below is a simple example demonstrating the use of the Angular PrimeNG FileUpload Auto Uploads.

• app.component.html

HTML

<h2 style="color: green">
  GeeksforGeeks
</h2>
<h4>
      Angular PrimeNG FileUpload
      Auto Uploads
</h4>

<p-fileUpload name="myfile[]"
              url="./upload.php"
              [auto]="true">
</p-fileUpload>

• app.component.ts

Javascript

import { Component, OnInit } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    providers: [],
})
export class AppComponent {
    constructor() { }
    ngOnInit() { }
}

• app.module.ts

Javascript

import { NgModule } from '@angular/core';
import { BrowserModule }
    from '@angular/platform-browser';
import { BrowserAnimationsModule }
    from '@angular/platform-browser/animations';
import { FileUploadModule } from 'primeng/fileupload';
import { AppComponent } from './app.component';
import { HttpClientModule } from '@angular/common/http';
import { ButtonModule } from 'primeng/button';

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        ButtonModule,
        HttpClientModule,
        FileUploadModule,
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
})
export class AppModule { }

Output:

    selector: 'app-root',
    templateUrl: './app.component.html',
    providers: [],
})
export class AppComponent {
    constructor() { }
    ngOnInit() { }
}

• app.module.ts

Javascript

import { NgModule } from '@angular/core';
