Koa VS Socket.io

Since "Express.js is an old framework that has not evolved for a long time. It's not a good choice for new projects since it can easily lead to security issues and memory leaks." -- H3. Which is also the case for Koa.

In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

The initial step is to create our entry point, from where the page will be rendered. In this case, we will use the koa framework.

Koa.js: By the team behind Express, Koa.js utilized async/await for middleware, resulting in cleaner and more readable code.

Koa -Next Generation Node Microservice Framework

Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

There are lot of different frameworks out there. If you learn one, there is no guarantee that the next job you find will use the same. For example if you learn Express and the next one used Koa or Nest.

Koa.js is a minimal and flexible Node.js web application infrastruc­ture, which provides a robust set of features for web and mobile applica­tions. It is an open-source framework developed and maintained by the creators of Express.js, the most popular web framework for Node.js.

Before diving into this tutorial, if you find microservices mysterious, check out my previous article for a detailed explanation. In this hands-on tutorial, we'll build a real-time chat server using Node.js, Socket.io, RabbitMQ, and Docker. Get ready for a practical journey into the world of microservices! Let's begin.

Socket.io Docs

Now we will be implementing socket logic using socket.io for building websockets. This library provides an abstraction layer on top of WebSockets, simplifying the process of creating real-time applications. For better maintainability, it is recommended to create a separate file for socket calls. To do this, navigate to the src folder, create a folder named services, and inside it, create a file named socket.ts under the services folder.

Hi I made a chat app using socket.io it worked fine locally but when i deployed the app on render.com socket is not working properly i have to refresh the page to see new messages please help...

Nextjs + socket.io.. Planning to use webrtc for video calls later

Implementação em Node usando Socket.io

I am using socket.io for real-time notification service. Previously my frontend part was deployed in Netlify and here the notification was not working properly as Netlify follows serverless architecture.

yes. Im running on DreamCompute currently. Discord.js and socket.io within same app. A dedicated server works too, but pricier.

No, not a library. More like, the frontend and backend just happen to need the same version to be compatible (socket.io is a good example, moment.js was the most basic I could think of).

For apps that require real-time communication, Socket.IO can be a valuable addition. It enables bidirectional, event-based communication between the server and client, making it an ideal choice for implementing real-time chat features.
