sqs-consumer VS Express

You could utilize a wrapper like sqs-consumer. Check out their implementation.

To receive the messages from the queue, we will use the sqs-consumer library. The service will receive messages describing newly created orders. After some processing, it will change the order status in the table to ‘completed’.

As we built out this new system, we looked at the current module ecosystem to determine if anything would fit our needs to keep this queue cleared. Unfortunately, the best module we could find, sqs-consumer, did not support FIFO queues and the issues indicated they did not have any intention to do so. Therefore, we wrote sqsiphon. Our library heavily borrows from the public interface of sqs-consumer, but is implemented in a much different way. In particular, sqsiphon leverages the Node.js event loop through setImmediate to build the polling mechanism instead of relying on SQS's "long polling" feature. Additionally, sqsiphon utilizes the JavaScript prototype to reduce reliance on expensive closures. As a bonus, OpenTracing support is built-in to sqsiphon so that applications built with it can be monitored effectively. The result is a library that can poll SQS extremely quickly while requiring very little overhead.

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Basic Knowledge of Express

Express.js Documentation

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.

Now we can install both Express and Socket.io libraries:

app.listen(3000); ``` Now you can run your server by executing `node index.js`. Your web application will be accessible at http://localhost:3000/, where you'll see "Hello, world!" displayed in your browser. Congratulations! 🎉 You've successfully set up basic routing with Express.js! This guide covered only the tip of the iceberg when it comes to utilizing Express.js features. Explore its extensive documentation (https://expressjs.com/) to discover more possibilities. Remember, with Express.js, you have the power to build efficient and scalable web applications. Happy coding!

Converting a large Express.js application from JavaScript to TypeScript can be a challenging task. For many applications, this represents a significant portion of their technical debt, as the process may span many days, if not months, and new changes are typically not allowed during the conversion.

Nitro is a nice https webserver that you can deploy everywhere. Comparing it to express, it doesn't need weird middlewares for json, it has a simple way to support caching, a file system router, tasks and scheduled tasks that avoid quite a few shell scripts, db:migrations etc, plugins, KV storages, SQL connectors, websockets...
