Upload, Compress and Delete Images In a AWS S3 Bucket With Node.JS + Express
The goal of this article
By the end of this article you will be able to create a simple API route to take an image and upload that image to your own AWS S3 Bucket, and then do amazing things with those images!
First, some non-code setup
To get started we will need to create an S3 Bucket as well as make some security credentials to be able to interact with the bucket via code.
1. Creating your S3 Bucket
- Log into your AWS account (don’t have one?) and then head over to the s3 service (via the dropdown or search).
- Then we are going to want to click the orange “Create Bucket” button.
- After that you will enter your bucket name along with security settings. Choose the ones that best fit your applications needs!
2. Generate your access keys on AWS
- On the top right you will see your AWS username. Click this and a dropdown should appear, once it does click “Security Credentials”
- Then you will want to click the “Access Keys” dropdown and click on “Create New Access Keys”
- And viola! Just write those down somewhere, we will need them for our code in the next step. ( It should go without saying, don’t share these! )
Our Server Code
For the means of simplicity and readability, the code will all be in a single file. All code is commented, and if you need a starting point on how you may get files on a client, here is a related article I wrote on how to do so in React.JS.
And as always I want my articles to be an entry point. If something is confusing or you are wondering why I did something in a particular way, play around with the code, look at some documentation, and just have fun!
