Purpose: get node.js running on local machine.

WINDOWS

1. create a directory for your project using file explorer and click into that directory. Example: D:\projects\react\testnodeserver
2. In Start type in power and when shown windows Powershell, select the Run as Administrator and enter Y
3. copy and paste the following line into powershell. This allows unsigned apps to run as YOU, not admin. Source URL https://stackoverflow.com/questions/63423584/how-to-fix-error-nodemon-ps1-cannot-be-loaded-because-running-scripts-is-disabl
4. Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
5. Close the powershell by clicking the X in the upper right.
6. Update or install Node and npm with the following lines. Source URL https://nodejs.org/en/download/
7. Download and install fnm:
8. winget install Schniz.fnm
9. Download and install Node.js:
10. fnm install 22
11. Verify the Node.js version:
12. node -v # Should print "v22.14.0".
13. Verify npm version:
14. npm -v # Should print "10.9.2".
15. install nodemon to help with restarting the local node server when your react file changes are detected. Source is Google's Gen AI search for "restart node.js windows". After installing, you run your node.js app with nodemon youappname.js Example: nodemon server.js
16. npm install -g nodemon
17. Save the following lines 18 - 28 into a file named server.js but you can actually call it whatever you want but have the extension named .js URL source https://nodejs.org/en/learn/getting-started/introduction-to-nodejs
18. const { createServer } = require('node:http');
19. const hostname = '127.0.0.1';
20. const port = 3000;
21. const server = createServer((req, res) => {
22. res.statusCode = 200;
23. res.setHeader('Content-Type', 'text/plain');
24. res.end('Hello World');
25. });
26. server.listen(port, hostname, () => {
27. console.log(`Server running at http://${hostname}:${port}/`);
28. });
29. Now run your app with: nodemon server.js
30. Copy the URL from the line displayed starting with "Server running at ". This will run your application which is the simple hello world app above. Example: http://127.0.0.1:3000/
