Amazon Simple Storage Service (Amazon S3) is object storage built to store and retrieve any amount of data from web or mobile. Amazon S3 is designed to make web-scale computing easier for developers. In this tutorial, we’re gonna create an Angular 4 App that can upload files to Amazon S3 Bucket.
More Practice:
– Angular 4 Amazon S3 example – How to get list Files from S3 Bucket
– Angular 4 Amazon S3 example – How to delete File from S3 Bucket
I. Technology
– Angular 4
– AWS SDK
II. How to do
1. Set up Amazon S3
1.1 Create an IAM user
We need to provide access permission bucket. So follow these step to create an IAM user and get Access key ID and Secret access key:
Go to https://console.aws.amazon.com/iam/
In the navigation pane, choose Users and then choose Add user.
Input User name, choose Programmatic access for Access type:
Press Next: Permissions button -> go to Set permissions for jsa-user screen.
Now, choose Attach existing policies directly -> filter policy type s3, then check AmazonS3FullAccess:
Press Next: Review:
Press Create user:
Press Download .csv for {Access key ID, Secret access key}.
1.2 Create Amazon S3 Bucket
– Go to https://console.aws.amazon.com/s3, click on Create bucket:
– Input information for creating bucket, then click on Create:
1.3 Configure CORS for Bucket
– Click on the Bucket we have just created:
– Choose Permission tab, then CORS Configuration:
– Configure CORS for Bucket, then click on Save button.
2. Install AWS SDK
Run this: npm install aws-sdk.
After installing, we can see aws-sdk inside node-modules folder:
3. Use AWS SDK
– import AWS and S3 from aws-sdk:
import * as AWS from 'aws-sdk/global'; import * as S3 from 'aws-sdk/clients/s3'; |
– use accessKeyId & secretAccessKey from the step above to construct S3 bucket.
– call S3 bucket upload() method with input params containing Bucket for bucket’s name, Key for full path, Body for data file.
const bucket = new S3( { accessKeyId: 'YOUR-ACCESS-KEY-ID', secretAccessKey: 'YOUR-SECRET-ACCESS-KEY', region: 'us-east-1' } ); const params = { Bucket: 'jsa-angular4-bucket', Key: 'jsa-s3/' + file.name, Body: file }; bucket.upload(params, function (err, data) { // ... }); |
III. Practice
1. Project Overview
1.1 Goal
We will build an Angular 4 Firebase App that can help user choose file from local and upload it to Amazon S3 Bucket:
1.2 Structure
2. Step by step
2.1 Set up Angular 4 Project integrating with AWS SDK
Create your own Angular 4 Project, then follow the steps above to integrate AWS SDK.
2.2 Setup @NgModule
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { FormUploadComponent } from './form-upload/form-upload.component'; import { UploadFileService } from './upload-file.service'; @NgModule({ declarations: [ AppComponent, FormUploadComponent ], imports: [ BrowserModule ], providers: [UploadFileService], bootstrap: [AppComponent] }) export class AppModule { } |
2.3 Upload Service
import { Injectable } from '@angular/core'; import * as AWS from 'aws-sdk/global'; import * as S3 from 'aws-sdk/clients/s3'; @Injectable() export class UploadFileService { FOLDER = 'jsa-s3/'; constructor() { } uploadfile(file) { const bucket = new S3( { accessKeyId: 'YOUR-ACCESS-KEY-ID', secretAccessKey: 'YOUR-SECRET-ACCESS-KEY', region: 'us-east-1' } ); const params = { Bucket: 'jsa-angular4-bucket', Key: this.FOLDER + file.name, Body: file }; bucket.upload(params, function (err, data) { if (err) { console.log('There was an error uploading your file: ', err); return false; } console.log('Successfully uploaded file.', data); return true; }); } } |
2.4 Form Upload Component
form-upload.component.html
<label class="btn btn-default"> <input type="file" (change)="selectFile($event)"> </label> <button class="btn btn-success" [disabled]="!selectedFiles" (click)="upload()">Upload</button> |
form-upload.component.ts
import { Component, OnInit } from '@angular/core'; import { UploadFileService } from '../upload-file.service'; @Component({ selector: 'app-form-upload', templateUrl: './form-upload.component.html', styleUrls: ['./form-upload.component.css'] }) export class FormUploadComponent implements OnInit { selectedFiles: FileList; constructor(private uploadService: UploadFileService) { } ngOnInit() { } upload() { const file = this.selectedFiles.item(0); this.uploadService.uploadfile(file); } selectFile(event) { this.selectedFiles = event.target.files; } } |
2.5 App Component
app.component.html
<div class="container"> <div style="color: blue; margin-bottom: 20px"> <h1>{{title}}</h1> <h3>{{description}}</h3> </div> <app-form-upload></app-form-upload> </div> |
app.component.ts
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { title = 'JavaSampleApproach'; description = 'Angular4-AmazonS3 Demo'; } |
2.6 Check Result
Run the App, go to http://localhost:4200/.
After uploading files:
– Console:
– S3 Bucket https://console.aws.amazon.com/s3/buckets/jsa-angular4-bucket/jsa-s3:
great article !!! thanks a lot
Thanks, turned hours of work in to 10 mins. Exactly what you want from a tutorial!
Hi, Ali can you please tell how to access the observable array which was returned from service?
I’m seeing a empty array when I try to print,but when clicked it gets expanded and shows data.
big file size issue the uploading files on s3 server. eg. 1GB files size.
Any luck on this one? How to tackle this?

Good article!
I learned easy to upload, thank you
Now I need to download the file. How do you download the file?
Hi wanderson,
You can visit this post for reference:
Angular 4 Amazon S3 example – How to get list Files from S3 Bucket
Regards,
JSA.
Hello,
I need to know if i want to upload to different folders in S3 and I want to make my angular app upload to a specific folder. is such thing can be done?
how could i upload multiple files at once to s3 bucket
Very good article. I am just concerned about security. Is it safe to use secret in Javascript?
accessKeyId: ‘YOUR-ACCESS-KEY-ID’,
secretAccessKey: ‘YOUR-SECRET-ACCESS-KEY’,
are exposed to user. Anyone can take these keys and submit anything to your bucket.
How will you prevent that?
Yes this is definitely a security problem with this approach of directly uploading files from the browser aka angular app. Then again you will have to choose whether you want the file to round trip via your server to S3 since that is lets say uploading a 100MB file first to your server and then to S3.
You are exposing private keys to any attacker and even go as far as providing them full access to your bucket.
i would like the component to receive the data object from the bucket.upload callback function. do you have any thoughts/guidance on this?
Hello Sir,
Thanks for your explanation.
I am getting the following error message when I try to upload using the aws-sdk in my angular 2 code.
zone.js:2935 OPTIONS https://lifelab-assets-main.s3.amazonaws.com/consent-form/abc.pdf 403 (Forbidden)
Failed to load https://lifelab-assets-main.s3.amazonaws.com/consent-form/abc.pdf: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:4200’ is therefore not allowed access. The response had HTTP status code 403.
There was an error uploading your file: Error: Network Failure
Please help me how to resolve this issue.
Thanks
Ankush
Hi Ankush,
Please make sure that you’ve done this step: Configure_CORS_for_Bucket.
Regards,
JSA.
Is there any tutorial for doing the above using AWS Cognito for authentication?
Hello
This works for me but only with smaller files.
I get a 403 (Forbidden) error then a CORS error to do with preflight
Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:4200’ is therefore not allowed access. The response had HTTP status code 403.
But it works with small files (<2mb)
What am I doing Wrong?
Hi, I have to upload at the below path domain_name/bucket_name/file_name i.e., https://s3.amazonaws.com/bucket_name/file_name and by your approach I am uploading at https://bucket_name.s3.amazonaws.com/file_name
How can I fix that? thanks.
Hello,
This works for me but i want add user defined meta data for uploaded file can you please help me with that
Nice tutorial,
This works for me but i want add user defined meta data for uploaded file can you please help me with that

If you look at the aws github bug here: https://github.com/aws/aws-amplify/issues/678 this error is reported as an issue when the library is installed in Angular 6.
Adding this line to polyfill.js will alleviate the issue until Angular 6 is able to resolve the base problem.
(window as any).global = window;
They (Angular) are attempting to deprecate global, so the answer may actually be in an update to aws-sdk. This stopgap worked perfectly for me.
https://github.com/aws/aws-amplify/issues/678 addresses this issue. It is specific to Angular 6, where they are working toward deprecating global.
A workaround is mentioned on that ticket (that worked for me) to add the following line to your polyfills.ts:
(window as any).global = window;
Thanks a lot it working fine for me
add this to head if you get my error
you can thank me on instagram : @dipesious
in pollyfills.ts
(window as any).global = window;I have this error when I tried to use this example Cannot read property ‘Stream’ of undefined and download your example and use my credentials and it work, but with angular 6 is not.

same 🙁
how to restrict to upload only xls file. ??
hey when i’m trying to upload file it gives 400 bad request erroe and then upload the file to aws
Hey All,
I got that buffer error, I did “types”: [“node”], but now I’m getting

What’s going wrong? I’m using angular 6.
Hello,
Thanks for a great tutorial.
But I think making ACCESS_KEY and SECRET_KEY exposed like this then it can a security disaster later. I just want to know how can we not put the keys out in the open and put it in the emvironment variables AWS.
Thank you.
You can define them in your config file and get them by using secured service.
I agree, this is the wrong approach if you need any kind of security. You can get a pre-signed S3 putObject request from some kind of server side environment like lambda that only lets you upload a specific file and exposes nothing to the client.
I’m trying to find a good client side example of that and spotted this article.
great article !!! thanks a lot
Thanks Man !!!! Saved lots of time 🙂
Hi, can some one help in finding the url of the image which is returned from observable.
//
this.fileUploads = this.uploadService.getFiles();
if I try to print “this.fileUploads” in console I get an object as response.
But when value in the object is printed in console,I get a empty array but it has some data when opened.
How to access the observable array for capturing the url’s of the image/file.
Getting the same cors error, and also the forbidden eroor
Which part of the sdk details these upload API ?
it’s extremely time consuming and I still cant find it… 🙁
is there a way that you can show the location right after the successful loading ?
it’s important to save the location path but i cannot figure out how to do it in form-upload.component.ts
1)Return promise in upload.service.ts
Ex:
2) consume promise in component.ts
