Build a gaiha.info-powered chatroom web app: node, mongodb and socket
This Node. In this series, you will learn how to setup Node. IO to add a real-time layer, and how to deploy it all together. The tutorial will use the optional Visual Studio and the Node.

I have provided links to free downlo of both tools. Part 1 — Introduction to Node. Part 2 — Welcome to Express with Node. Part 5 — Connecting the Chatroom with WebSockets.
How to create a professional chat api solution with sockets in nodejs [beginner level]
Welcome to Part 3 of the hands-on Node. In this installment, I will show you how to use your existing express-based Node.
WebSocket is a protocol chat mongo to allow web applications to create a full-duplex channel over TCP i. WebSocket has allowed web applications to become real-time and support advanced interactions between the client and the server.
It simplifies the process of using WebSockets ificantly. We will be using Socket. IO v1. Take a look at this interactive explanation of package.
Mongodb, express, gaiha.info 2, gaiha.info (mevn) and socketio chat app
This will install Socket. IO into your project and add it to the package. The next step is to add Socket.
IO to app. You can achieve this by replacing the following code….

IO module can attach to it. The last code block takes the chat mongo variable and executes the listen function which starts the HTTP server.
Ideally, we want to log a user ing the chatroom. The following code accomplishes that by hooking a callback function to be executed on every single connection event via Chat mongo to our HTTP server.
In the callback function, we call console. We can add this code after we call serve.

To do the same for when a user disconnects, we have to hook up the disconnect event for each socket. Add the following code inside after the console log of the code block. Any message received on the chat channel will be broadcast to all the other connections on this socket by calling chat mongo with the broadcast flag in the callback.
The chatroom should save chat messages to a simple data store. Normally, there are two ways to save to a database in Node; you can use a database-specific driver or you can use an ORM. Chat mongo this tutorial, I will show you how to save the messages to MongoDB. You should make sure chat mongo have a MongoDB to connect to.
It is not best practice to add sensitive information such as this URI into your code or into a configuration file in your source code management tool. The next step is to add support for MongoDB to our project. You can do that by adding the following line to the dependencies chat mongo in package. Make sure to save your changes to the file.
Deploying gaiha.info on ubuntu
Right-click on the npm part of the project in the Solution Explorer to chat mongo the right-click context menu. We want to import that module to be able to use the MongoDB client object in app. You can add the following lines of code after the first require '' function calls, such as on line Once connected, we want to insert the chat message received in the socket connection. As you can see in chat mongo above code, we use the process.

We go chat mongo a collection in the database and we call the insert function with the content in an object. To do that, we need to connect MongoDB.
In this case, I chat mongo refraining from wrapping all of the chat mongo code with one connection to the database so that I can still have the server working even if it loses the database connection. We will stream the from MongoDB so that I can emit them as soon as possible to the chatroom chat mongo they arrive.

You can redeploy to Azure by following the past tutorials such as part 2. In conclusion, we have a chat system capable of broadcasting a message received via WebSockets to all other connected clients.
The system saves the message to the database and retrieves the last 10 messages to give context to every new user who s the chatroom.
