How to send files in Angular 9 application?

Hello to all, welcome on therichpost.com. In this post, I will tell you, How to send files in Angular 9 application?

Post Working:

In post, I am sending files or images to my laravel backend in my Angular 9 application.

Here is the code snippet and please use carefully:

1. Here is my HTML code for app.component.ts file:

<form #f="ngForm" (ngSubmit)="onSubmit(f)">
<input type="file" #fileupload [(ngModel)]="myFile" name="myFile" (change)="fileEvent($event)"/>
<button>Upload Image</button>

2. Here is my code for app.component.ts file:

...
import { HttpClient, HttpHeaders } from '@angular/common/http';
import {NgForm} from '@angular/forms';
...

filedata:any;

//File onChange event, where I am getting the file details
fileEvent(e){
        this.filedata = e.target.files[0];
    }

constructor(private http: HttpClient) {}

//Form Submit Function
onSubmit(f: NgForm) {

          var myFormData = new FormData();
          const headers = new HttpHeaders();
          headers.append('Content-Type', 'multipart/form-data');
          headers.append('Accept', 'application/json');

          // store file details into formdata
          myFormData.append('image', this.filedata);

          //HTTP Angular service, which will send call to Laravel API With headers and myformdata
          this.http.post('http://localhost/blog/public/api/sample-restful-apis', myFormData, { headers: headers }).subscribe(data => {
          console.log(data);
      });
        
      }

3. Code for app.module.ts file:

...
import { HttpClientModule } from '@angular/common/http';
import { FormsModule }   from '@angular/forms';
...

...
imports: [
    ...
    HttpClientModule,
    FormsModule,
    ...
  ],
...
