hyper-express VS Express

Hey, I believe uWebsockets.js does support clustering. I'm the author of https://github.com/kartikk221/hyper-express which is written on top of uWebsockets.js and is pretty much the fastest webserver in Node land with an Express-like API and all of the common features such as middlewares, Router, async/sync, Websockets, Server Sent Events, File Uploading in a single package that is about same size as Express. The only catch is that you lose about 14% performance from the uWebsockets.js peak because of all the features but this is being improved and a well worth trade off for the familiar developer experience with still almost 2.5x performance of Fastify and other similar frameworks.

Yeah I’m personally of the opinion that the performance loss for regular web services is worth it 99% of the time. RAM is cheap, human time is not.

That said I definitely believe your characterization of resource hunger between nginx and traefik.

You are the second person to mention using websockets for requests in as many days… How do you deal with scale out? Sticky cookie routing seems like almost a requirement if you don’t want to deploy a redis-alike.

Also just out of curiosity, do you use hyper-express[0]?

Building your own webserver on top of a lower level networking library in Node.js can be a good way to learn all 3 of those things. I have built a webserver called HyperExpress which is essentially a layer on top of a low level C++ websever called uWebsockets and I had to utilize and progress my knowledge in buffers, emitters and streams to achieve the same API as Express.js and make it usable for Node.js applications: https://github.com/kartikk221/hyper-express Feel free to dig around in the code and make any PRs for improvements!

Are classes absolutely needed in JS? No, not really. Are classes really nice and significantly improve the readability/flow of your code in some cases? Sure, an example could be a webserver I wrote: https://github.com/kartikk221/hyper-express

Now, we will create API using expressjs. When we created application using --ssr flag, the Angular CLI already took care of installing expressjs for us.

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.
