Angular - upload file as base64

json angular rest file-upload base64

For sending big files to server you should use FormData to be able to send it as multi-part instead of a single big file.

Something like:

// import {Http, RequestOptions} from '@angular/http';uploadFileToUrl(files, uploadUrl): Promise<any> {  // Note that setting a content-type header  // for mutlipart forms breaks some built in  // request parsers like multer in express.  const options = new RequestOptions();  const formData = new FormData();  // Append files to the virtual form.  for (const file of files) {    formData.append(file.name, file)  }  // Send it.  return this.http.post(uploadUrl, formData, options);    }
