Image uploading in Angular

Question

I was trying to upload an image using Angular to a google storage bucket. And everything is working fine with Postman. But I'm stuck with angular typescript. Can anyone suggest to me a way to do this?

.html file

 <input type="file" accept="image/png, image/jpeg" class="form-control upload-btn" formControlName="imageUpload" placeholder="Upload Images" (change)="uploadImage($event)"  required>

.ts file

 uploadImage(event: any) {
if (event.target.files && event.target.files[0]) {
  const uploadImage=event.target.files[0];

  const fileObject = {
    userId: this.userId,
    bucketName: 'Test123',
    image: uploadImage
  };

  this.userService.uploadImage(fileObject).subscribe(data=>{
  },err=>{
    console.log("error occured")
  }
  )
}

}

.service file

uploadImage(fileObject: any){
return this.http.post('http://localhost:1337' + 'upload-image' , fileObject);

}

No any error occurs on the backend side. It worked fine with Postman. Im not sure about the .ts file.

Hi @chintuyadavsara, error is it will never go inside this.userService.uploadImage(fileObject).subscribe(data=>{ } this one. Therefore image didn't add the bucket — Dasaya_Developer

Hi @ManektechKnowledgeBase, I used http://localhost:1337/upload-image this url which is same as in the service file. — Dasaya_Developer

As suggested by @PrasenjeetSymon using FormData will help to upload images in Angular.

Here is the similar thread which demonstrate how to use FormData

You can use the tag from HTML:

<input type="file" name="file" id="file" (change)="onFileChanged($event)" />

and in the component:

public files: any[];

contructor() { this.files = []; }

onFileChanged(event: any) {
  this.files = event.target.files;
}

onUpload() {
  const formData = new FormData();
  for (const file of this.files) {
      formData.append(name, file, file.name);
  }
  this.http.post('url', formData).subscribe(x => ....);
}
