Express chat room

    After the user enters the room and fills the username or nickname then the user enters the chats with other users. Now that our server is up and running, we need to create our database. See part 1 of this tutorial series: Introduction to Node. Express chat room [PUNIQRANDLINE-(au-dating-names.txt)

    During development, socket. That will install the module and add the dependency to package.


    Notice that I initialize a new instance of socket. Express chat room I listen on the connection event for incoming sockets, and I log it to the console. The main idea behind Socket.

    IO is that you can send and receive any events you want, with any data you want. Any objects that can be encoded as JSON will do, and binary data is supported too. The script section in index. Express chat room you want to send a message to everyone except for a certain socket, we have the broadcast flag:. The total client-side JavaScript code now amounts to:. You can find it on GitHub here. The web framework The first goal is to setup a simple HTML webpage that serves out a form and a list of messages.

    MongoDB, Express, Vue.js 2, Node.js (MEVN) and SocketIO Chat App

    The first thing we need to create is a server. In order to create that, we will be making use of a framework named Express. Express provides a robust set of features for web and mobile applications.

    Express provides a thin layer of fundamental web application features, without obscuring Node. In this file we need to require Express and create a reference to a variable from an instance of Express. Now we need to create an HTML file index. I have added bootstrap and JQuery cdn.

    In-order to tell Express that, we will be using a static file. We will add a new line inside server. We will download nodemon using the command.

    Now that our server is up and running, we need to create our database. I am setting up my mongodb in mlab. Our database will contain a single collection called messages with fields express chat room and message.

    In-order to connect this database to the app, we will use another package express chat room Mongoose. Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Mongoose can be installed using the command. We can implement the chat logic now. But before that there is one more package that needs to be added. Body-Parser extracts the entire body portion of an incoming request stream and exposes it on req. The middleware was a part of Express.

    In order to connect these routes to the front end we need to add the following code in the client express chat room script tag in the index. Here the sendMessage is used to invoke the post route of the messages, and save a message sent by the user.


    The message is created when a user clicks the send button. Similarly the getMessage is used to invoke the get route of messages. Next, go to the newly created Vue.

    Build a Chat App With MongoDB & [Part 1]

    Close the running Vue. You will see the previous Vue. We need to access data from MongoDB. For express chat room, we will install and configure Mongoose. On the terminal type this command after stopping the running Express server. Next, you can test the connection to MongoDB run again the Node application and you will see this message on the terminal. If you are still using built-in Mongoose Promise library, you will get this deprecated warning on the terminal.

    Add a models folder on the root of project folder for hold Mongoose. Run again the Express server then open the other terminal or command line to test the Restful API by type this command.
