海外TECH	DEV Community	Making your very own WebSocket Server with Javascript	https://dev.to/smpnjn/making-your-very-own-websocket-server-with-javascript-119a	Making your very own WebSocket Server with JavascriptA lot of the work we do with Javascript involves us sending information back and forth from servers You are probably familiar with the concept of APIs which send data to servers or websites in a particular format to get a specific response back These are known as REST APIs Although useful they are not very good at constant streams of data If you try to do something realtime with REST APIs you re going to have a bad time Fortunately if we want a realtime connection with a user we have an alternative known as WebSockets How WebSockets workFor this tutorial we will assume you are familiar with Node JS WebSockets are essentially constant connections made between the server and your computer When you access a website it can send a GET request to the server to initiate a WebSocket connection between the user and the server WebSocket vs REST APIIf the user leaves the website the connection is cut so the user only has access to the WebSocket as long as they continue to use the website How long can a WebSocket stay open Once a WebSocket is created it can theoretically stay open forever There are a few exceptions to this The server goes down this will break the WebSocket but we can attempt to reconnect to it A power outage or internet connection problem the connection will break if the user s internet stops Inactivity if the user doesn t interact or send data through the WebSocket the connection inevitably times out As such when we design our WebSocket we need to consider how we reconnect to them if the user s connection stops for some reason as to not interupt the user s experience Making a WebSocketA WebSocket therefore consists of two parts the server and the local machine that the user is using For what we are doing we ll be using Node JS as our server but other languages also support WebSockets When the user access our website we load a file with some Javascript which contains a connection string to our WebSocket Meanwhile in our backend we will have WebSocket set up that the user will connect to This is shown in the below diagram Step Creating our ServerLet s start by making our Node JS web server for the WebSocket connection For this we re going to be using an express server with an additional package called express ws This additional package will allow us to use ws in the same way we might use get with express If you don t have Node JS installed you ll need to do that first by going to this link Once installed create a new folder called server websocket Open terminal and use cd to move into that folder if you don t know about cd read my article on it here Create a folder for your WebSocketOnce in the folder you need to install the dependency packages Start installing your dependencies by running each of the following commands npm i expressnpm i express wsnpm i pathnpm i urlAfter that make a file called index js and put in the following code Import path and url dependenciesimport path from path import fileURLToPath from url Get the directory and file pathconst filename fileURLToPath import meta url const dirname path dirname filename Import express expressWs and httpimport express from express import expressWs from express ws import http from http Our portlet port App and serverlet app express let server http createServer app listen port Apply expressWsexpressWs app server app use express static dirname views Get the route app get req res gt res status send Welcome to our app This lets the server pick up the ws WebSocket routeapp ws ws async function ws req After which we wait for a message and respond to it ws on message async function msg If a message occurs we ll console log it on the server console log msg Start listening for messages The last clause app ws refers to the WebSocket and that s what we ll try to connect to on the frontend For the time being the WebSocket only console logs a message whenever it receives one from the frontend Let s change that so it sends something back Get the ws websocket routeapp ws ws async function ws req ws on message async function msg What was the message console log msg Send back some data ws send JSON stringify append true returnText I am using WebSockets Now whenever this WebSocket connection receives data it will send back the object containing append and returnText We ll also console log the message that the server has received We can then manipulate this object in our frontend to display or change views for the user Save that file in your websocket server folder as index js Then from your terminal in the websocket server folder run the following command node index js Step Connect on FrontendNow we have a running WebSocket server but no way to connect to it We want to achieve something like this A user visits our site We initiate a WebSocket connection from our Javascript file The user successfully connects to the WebSocket and sends a message to the WebSocket once connected We can then send data back to the user now that they have a live connection to our WebSocket server creating real time data exchange For our demo let s start by making two files index html and local js both of which will be front end files Next let s put the following in our index html file lt script src local js gt lt script gt lt p gt Welcome to WebSockets Click here to start receiving messages lt p gt lt button id websocket button gt Click me lt button gt lt div id websocket returns gt lt div gt Next we need to connect the user to our WebSocket via the local js file Our local js file will ultimately look like this connect Connect to the websocketlet socket This will let us create a connection to our Server websocket For this to work your websocket needs to be running with node index jsconst connect function Return a promise which will wait for the socket to open return new Promise resolve reject gt This calculates the link to the websocket const socketProtocol window location protocol https wss ws const port const socketUrl socketProtocol window location hostname port ws Define socket If you are running your websocket on localhost you can change socketUrl to http localhost as we are running our websocket on port from the previous websocket code socket new WebSocket socketUrl This will fire once the socket opens socket onopen e gt Send a little test data which we can use on the server if we want socket send JSON stringify loaded true Resolve the promise we are connected resolve This will fire when the server sends the user a message socket onmessage data gt console log data Any data from the server can be manipulated here let parsedData JSON parse data data if parsedData append true const newEl document createElement p newEl textContent parsedData returnText document getElementById websocket returns appendChild newEl This will fire on error socket onerror e gt Return an error if any occurs console log e resolve Try to connect again connect isOpen check if a websocket is openconst isOpen function ws return ws readyState ws OPEN When the document has loadeddocument addEventListener DOMContentLoaded function Connect to the websocket connect And add our event listeners document getElementById websocket button addEventListener click function e if isOpen socket socket send JSON stringify data this is our data to send other this can be in any format This might look like a lot but let s break it down In our connection function we start by constructing our WebSocket URL This can simply be written as ws localhost since our WebSocket server runs on port Above it is configured to adjust automatically should you be using HTTP or HTTPS We then pass some event listeners to our newly created WebSocket All of our event listeners and the URL to connect to the WebSocket server sit within our connect function the purpose of which is to connect to our WebSocket server Our WebSocket event listeners look like this socket onopen if the connection is successful and open this fires socket onmessage any time the server sends a message to us this fires In our example we will append a new element to our user s HTML if they receive data which has append set to true socket onerror if the connection is fails or an error occurs this will fire Now that we have a connect function which lets us connect to our WebSocket server we have to run it We start by waiting for the page to load using DOMContentLoaded Then we connect to our WebSocket using the connect function Finally we attach an event listener to the button on our HTML page which when clicked will now send some data to our WebSocket using the socket send function When the server receives this data it then sends back its own data as the servers message event will fire When the document has loadeddocument addEventListener DOMContentLoaded function Connect to the websocket connect And add our event listeners document getElementById websocket button addEventListener click function e if isOpen socket socket send JSON stringify data this is our data to send other this can be in any format Since our onmessage event handler on our WebSocket fires whenever new data comes from the WebSocket server clicking the button causes the WebSocket server to send a message back to us thus creating a new HTML element ConclusionNow we have a functioning WebSocket which allows you to send data to the server and back to the user This two way connection can be used to allow users to interact with the server itself and even send data to other users should you wish to Here are some useful links to learn more about WebSockets
