ws VS Express

Before setting up a WebSocket server in Node.js, we need to install the necessary dependencies. Fortunately, Node.js has a vibrant ecosystem with various WebSocket libraries available. In this article, we will focus on using the popular ws library, which provides a simple and efficient WebSocket implementation for Node.js.

WS has a user base of 17.7 million people and over 20,000 forks. It also has clear and concise documentation, with examples and API references, to help developers understand how to integrate it into their projects.

In order to implement websockets, you can use a nodejs library named ws. It provides a fast and simple way to establish a websocket connection.

Next, you can use a library like chokidar to listen for changes in your source directory. Create a ws server, and whenever a file changes, send a message.

I use redis, sequelize and PG Listen/Notify via Robust Listeners with a websocket server coded in ws

With over 19k stars on GitHub and about 60 million weekly downloads on npm, ws is one of the most popular open-source libraries for real-time web application development

Nest supports 2 websocket platforms - socket.io and ws. We're going to be using socket.io.

I'm trying out Render.com as a potential replacement for Heroku to host and run my code, which uses Node, Express, and the ws package to connect a game made on Godot Engine and the webapp, using a Websocket connection. However, when I migrated the code over, I've noticed that the game lasts barely a quarter of the way before the server aborts the Websocket connection for literally no reason. I'm serious, it's what the log says:

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.

express - one of the most popular middleware tools, lightweight and easy to learn. docs

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...

ExpressoTS fully supports Express middleware.

As you might have seen from this PR and in our forums Meteor v3(it is still in beta, but you can follow the progress here) will be released with a new engine, expressjs.
