ws VS Pusher

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:

Pusher Channels is a real-time notifications service that empowers developers to swiftly integrate real-time functionality, like live notifications and chat, into web and mobile apps using WebSockets. Pusher is known for reliability and scalability and is used by Buffer, GitHub, and Datadog.

Pusher

Typically, you don't do websockets. There are some great products out there that give you the same capabilities. I recently started working with Pusher for my Remix applications and am loving it!

According to Vercel's website SocketIO is NOT supported, however Pusher Channels is recommended in it's place. Not sure what it is, but it supposedly is supported by vercel and potentially can help.

Pusher is a hosted service that makes it super-easy to add real-time data and functionality to web and mobile applications. It sits as a real-time layer between your servers and your clients. Pusher maintains persistent connections to the clients — over WebSocket if possible and falling back to HTTP-based connectivity — so that as soon as your servers have new data that they want to push to the clients they can do, instantly via Pusher.

Then watchPosition from @react-native-community/geolocation is definitely the way to go. Here's a link to the example in their repo. This will constantly update the position state variable, which you can then send to a realtime service which other users are subscribed to and consuming. (Depending on your implementation, could be a websocket or some pub/sub service... I've worked with Pusher Channels before for something similar.)

An easy way to start with is to use external Pusher channels service It requires 0 devops and everything works very well, for free at least at the beginning. However, like any external service, it can't scale without paying. "Pay as you grow".

I see that NextJS now recommends a pub/sub approach Vercel Support Your client will need to subscribe to the events from a 3rd party service like Pusher Channels and the Pub should be handled by a serverless function

Centrifugo is very similar to pusher.com Channels product (https://pusher.com/channels) – but self-hosted. Also – somewhat similar to socket.io - but not a library, so can work with any backend. Centrifugo is pretty unique in terms of available features sum – so can't say that there is a direct analogue I've heard about - sth from one product, sth from another, sth unique. And of course there are alternatives which can do what Centrifugo can't since the market of real-time servers is quite big.
