Socket.io VS Nodemon.io

Repository: Socket.io

When developing web applications, you might encounter connectivity issues between your client and server when using Socket.io on localhost.

There are various libraries that let you create a ws server (similar to how express lets you create an HTTP server) https://www.npmjs.com/package/websocket https://github.com/websockets/ws https://socket.io/

Previously we created a chat with pusher. but this time we are going to do it with Socket.io. Socket.io is a NodeJS library. With it we can create our own servers. This is cheaper than using pusher server and we have more control on the code.

The first is the script tag in the head of our HTML document that loads the Socket.IO client library. This script tag includes the Socket.IO client library that will communicate with our socket.io server from the code above.

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...

But what is a symbolic link exactly? It comes from programming and I often liken symbolic links to basic redirects but with greater stability. However, not every package needs a place in .bin. Packages like nodemon, webpack, gulp, eslint and create-vue are found in .bin because they need to be executed. On the other hand, packages like animate.css, swiper and express operate at the application layer, so you won't find them in .bin after installation. How does npm determine whether a package is executable or not? It's simple: by using the bin property in your package.json to specify the executable path. If your package is executable, you can set it accordingly. Let's take a look at prettier's package.json file

With the release of Node.js 22, this feature has been stabilized, so this warning no longer appears. While you could previously use a third-party tool like nodemon, this update removes the need for a dependency by adding it directly to Node.js core.

nodemon - enables automatic reload of your server after code change docs

Then, install nodemon (in the VSCode terminal also), which, to my understanding, automatically refreshes the server you'll be sending requests to, whenever you make a change. Using plain node.js, you'd have to manually stop and restart the server after every change.

That's already pretty good, but as you already know it's a PITA to work with this during development. You will have to rebuild your Docker images whenever you change your code, even though your apps will probably support hot-reloading out of the box (or with something like Nodemon if not).

Are you moving your projects to use ES Modules but you are facing some unexpected issues? You are not alone in this fight. In this tutorial, you will learn how to set up nodemon along with ts-node.

We can now use npm run dev to start the server using nodemon, which enables hot refreshing on changes.

Welcome to my blog, where we dive into the intriguing world of Node.js development and tackle one of the common stumbling blocks many developers encounter: the "Nodemon Error - nodemon.ps1 cannot be loaded because running scripts is disabled on this system." If you've ever come across this error while working with Nodemon, fear not! In this article, we will explore the causes behind this issue, understand why scripts are disabled on certain systems and most importantly, provide you with practical solutions to overcome this obstacle and keep your development workflow seamless. So, let's embark on this troubleshooting journey together and empower ourselves to conquer the Nodemon Error!
