README.md

a test? experiment? proof of concept?

The NodeJS server renders the pages, we send the requests to the Java server and render the results. That's basically it.

What you need:

1. Nodejs
2. Java 11 (jdk sha when you open vscode it will tell you to download it)
3. VSCode
4. The VSCode Java Extension Pack
5. Maven (not necassary tbh)
6. Download thes Jackson JAR files and save them in something like: c://dev/jarDownloads/*.jar
7. Add the packages to your workspace from VSCode...
8. NPM

I think that's all you need. I will update this sha...

To get started:

1. Fork the repo or something
2. Get it on your local machine
3. Get everything you don't have in "What you need". Pay attention to the versions lol
4. Open 2 vscode windows. One for Client and the other for SocketServer (if you want but I found this to be optimal for now)
5. Run npm install from the Client directory
6. After the Node modules have installed, go to the Java server and click the play button besides SocketServer in the 'Java Projects' panel. (it's bottom left)
7. If it runs successfully you should see 'waiting for connection...'
8. THEN you run the Nodejs server by doing node server.js from the Client directory. The order is important. Always start the Java before the Node.
9. Go to localhost:3000
10. Voila! It should work lol

• the java server might be stuck waiting for the end of the clients request => https://stackoverflow.com/questions/55870574/cant-send-data-from-java-socket-server-to-nodejs-client NOTE: the end of every request from the nodejs server is a new line '\n' because that's how Java will know the line has ended! If there's no new line it will think more data is coming and will hang...
