If you're a developer working with Amazon Web Services (AWS), you're probably familiar with the AWS SDK for JavaScript. This SDK has been a popular choice for integrating AWS services into web applications for years, but with the recent release of version 3 of the SDK, developers now have access to a number of new and improved features. In this post, we'll take a look at some of the benefits of using the new AWS SDK for JavaScript v3.

Modular Architecture

One of the most significant changes in the AWS SDK for JavaScript v3 is the modular architecture. Unlike version 2, which required developers to import a monolithic package, version 3 is now available as individual modules, allowing developers to only import the modules they need. This results in faster build times and greatly reduced bundle sizes. For example, if you need too use DynamoDB, you download the @aws-sdk/client-dynamodb package.

For instance, if all I need from the SDK in this website is S3 and presigned URLs, I'll download the @aws-sdk/client-s3 and the @aws-sdk/s3-presigned-post packages.

import { S3Client } from "@aws-sdk/client-s3";

const s3 = new S3Client({
  region: env.NEXT_PUBLIC_AWS_REGION,
  credentials: {
    accessKeyId: env.AWS_ACCESS_KEY_ID,
    secretAccessKey: env.AWS_SECRET_ACCESS_KEY,
  },
});

import { createPresignedPost } from "@aws-sdk/s3-presigned-post";

 const { url, fields } = await createPresignedPost(s3, {
          Bucket: env.BUCKET_NAME,
          Key: `${userId}-${randomKey}`,
          Expires: uploadTimeLimit,
          Conditions: [
            ["starts-with", "$Content-Type", "image/"],
            ["content-length-range", 0, maxFileSize],
          ],
        });

Support for TypeScript

The AWS SDK for JavaScript v3 includes full support for TypeScript, making it easier to write type-safe code and catch errors at compile-time instead of runtime.

Improved Browser Compatibility

The AWS SDK for JavaScript v3 has improved compatibility with modern web browsers, making it easier to integrate AWS services into web applications. This means that developers can now use the AWS SDK for JavaScript v3 with confidence that it will work in a wide range of browsers.

Conclusion

The AWS SDK for JavaScript v3 is a major upgrade from version 2, and brings a number of new and improved features to developers working with AWS services. Its modular architecture, support for Promises and async/await, improved error handling, support for TypeScript, and improved browser compatibility all make it a great choice for building modern web applications. If you haven't already, we highly recommend giving the AWS SDK for JavaScript v3 a try for your next AWS integration project.
