Setting up a simple Node.js Server

You can try Node.js by using your Port Allocation on the The MetaArray to run your own Node.js server. What follows is a bare-bones 'Hello, World' example tailored for the metaarray:

  1. go to a project folder in your user folder, say ~/projects/nodejstest
  2. use your favorite editor to open a new file called app.js
    • paste the following code into the file:
      const http = require('http');
           //const hostname = '*put your mkhomepg-selected meta-array domain name here, remove the // at the beginning and delete next line*'; 
           const hostname = '';
           //const port = *replace this with your UID as port number, uncomment this line, then delete the line below*;
           const port = 8388;
           const server = http.createServer((req, res) => {
           res.statusCode = 200;
           res.setHeader('Content-Type', 'text/plain');
           res.end('Hello World, this is node');
            server.listen(port, hostname, () => {
              console.log(`Server running at http://${hostname}:${port}/`);
  3. run the server with node app.js
  4. OMG that was so easy, right? Check it out with a browser pointed to your metaarray website but at your UID port, for example
    • it should look like the image to the right browser showing 'Hello World, this is node'
  5. quit the server with ctl-c
  6. knock yourself out doing more cool stuff with javascript on the server!
