Streamlined Image Processing with Node.js: Download, Resize, and Upload to S3
In today’s digital world, managing images efficiently is crucial for optimizing performance and saving storage space. If you’re transitioning your image management to the cloud with Amazon S3, you may find yourself wanting to download images, resize them, and then upload them to S3 without the need to store anything locally first. In this post, we’ll tackle how to achieve this using Node.js, along with the node-fetch and sharp libraries.
Understanding the Problem
When migrating images to an S3 cloud storage, you want to ensure that they are resized appropriately. This not only helps save on storage costs but also improves loading times when serving images to users. The challenge lies in processing images directly in memory, avoiding the overhead of saving them to disk. Here, we’ll break down the steps to solve this using Node.js.
The Solution Explained
Required Libraries
Before you dive into the code, ensure you have the following libraries installed in your Node.js project:
dotenv: To manage environment variables.
node-fetch: To fetch images from external URLs.
sharp: To resize the images.
aws-sdk: To interact with Amazon S3 services.
Install these by running:

Conclusion
By following the steps outlined above, you can easily download, resize, and upload images to S3 without saving them to your local machine. This method streamlines the process and helps you manage your resources effectively. Whether you're migrating to S3 or just looking for an efficient way to handle your image assets, using Node.js with node-fetch and sharp is a powerful solution.
Feel free to modify the example to suit your needs, and happy coding!
