This is a little example repo of a web page in html, css and javascript that will request an info (in this case a random int between 0 and 100) to a server that is also in the repo.
You can clone the repo or download the zip.
You need to have nodejs 16 or newer installed on your computer to be able to run the server. (tested with nodejs 20)
Once in the project folder, simply run the npm run test command in a command prompt and the server will start to listen on the port 3000
Any request made to http://localhost:3000 will lead to a "hello world" response except for the /random route that will lead to a json formatted response of a random generated number as the result field.
Do not hesitate to modify the scripts ! This is just an example project made for new web devs and where you can understand the basics of a http get request and the server side handling part.
