Angular PrimeNG FileUpload File Size

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. This article will show us how to use FileUpload File Size in Angular PrimeNG.

Example 1: Below is a simple example demonstrating the use of the Angular PrimeNG FileUpload File Size. In this example, we are setting maxFileSize to 1B.

• app.component.html:

HTML

<h2 style="color: green">GeeksforGeeks</h2>
<h4>Angular PrimeNG FileUpload File Size</h4>

<p-fileUpload
    [maxFileSize]="1"
    mode="basic"
    chooseLabel="Upload">
</p-fileUpload>

• app.component.ts:

Javascript

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

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

• app.module.ts:

Javascript

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

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

Output:

Example 2: Below is another example demonstrating the use of the Angular PrimeNG FileUpload File Size. Here the max uploaded file size is set to 1 MB so files less than 1MB in size can be uploaded.

• app.component.html:

HTML

<h4>Angular PrimeNG FileUpload File Size</h4>

<p-fileUpload
    [maxFileSize]="1000000"
    [multiple]="true">
</p-fileUpload>

• app.component.ts:

Javascript

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

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

• app.module.ts:

Javascript

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

@NgModule({
    imports: [
        BrowserModule,
