Initializing a server

After we've created the application, we are ready to initialize a server for it.

Let's create a server.js file in our project directory:

'use strict';

const jstp = require('@metarhia/jstp');
const chatApp = require('./chatApp');

const PORT = 3000;
const server = jstp.ws.createServer([chatApp]);

server.listen(PORT, () => console.log(`Server listening on port ${PORT}...`));

In this example we are using WebSocket as a transport, other available transports are TCP and Unix domain sockets, secure transports like WebSocket Secure and TLS are also supported.

Here we have passed an array of applications (in our case just one chat app) to createServer because JSTP server can serve multiple applications. As we've chosen WebSocket as transport, jstp.ws module is used.

const server = jstp.ws.createServer([chatApp]);

At the next step, the server starts listening on the specified port and is ready to accept connections. The second argument is automatically set as a listener for the server's 'listening' event, which will be emitted when the server will have been bound.

server.listen(PORT, () => console.log(`Server listening on port ${PORT}...`));

For additional information jstp.Server in API Documentation.

Now you can start your server and see something like this:

$ node server.js
Server listening on port 3000...

So let's now look into how we can connect to the server and work with remote APIs.
