],

imports: [

   BrowserModule,

   AppRoutingModule,

   FormsModule, // required for input file change detection

   ReactiveFormsModule,

   HttpClientModule, // this is required for the actual http request

],

providers: [],

bootstrap: [AppComponent]

})

export class AppModule { }

Set up upload button and set invent in app.component.html

<div class="container"> 
 <div class="row mt-5">  
  <div class="col-md-4">   
   <div class="mb-3">  
      <label for="formFile" 
class="form-label">Upload file 
example</label>        
<input (change)="this.onFilechange($event)" 
class="form-control" 
type="file" id="formFile"> 
       <button (click)="this.upload()" 
type="button" 
class="btn btn-primary mt-3">Upload</button> 
     </div>
    </div>
  </div>
 </div>

Wait for the button to click, and send the selected file to the upload service inapp.component.ts.

import { UploadService } from './upload.service';
import { Component } from '@angular/core';
 
@Component({
 selector: 'app-root',
 templateUrl: './app.component.html',
 styleUrls: ['./app.component.css']

export class AppComponent {
 
 file: File = null;
 
 constructor(

 ){
 
 }
 
 onFilechange(event: any) {
   console.log(event.target.files[0])
   this.file = event.target.files[0]
 }
 upload() {
   if (this.file) {
     this.uploadService.uploadfile(this.file).subscribe(resp => {
       alert("Uploaded")
     })
   } else {
     alert("Please select a file first")
   }
 }
}

Set service controllers for communications and network calls through upload.service.ts this takes care of the upload process

import { Upload Service } from './upload. Service';
import { Component } from '@angular/core';
@Component ({
 selector: 'app-root',
 template URL: './app.component.html',
 styleUrls: ['./app.component.css']
})
export class AppComponent { 
 file: File = null;
 constructor(
   private uploadService: UploadService
 ){
 
 }
 
 onFilechange(event: any) {
   console.log(event.target.files[0])
   this.file = event.target.files[0]
 }
 
 upload() {
   if (this.file) {
     this.uploadService.uploadfile(this.file).subscribe(resp => {
       alert("Uploaded")
     })
   } else {
     alert("Please select a file first")
