This is a MERN stack website to help teach java programming by offering a custom in-code statement highlighter to help visualize the program's execution step-by-step. It allows for the creation of exercises by the maintainers which can then be solved by the students. Code is executed on the backend, eliminating the requirements for any additional software having to be installed on the students side. Nevertheless, optionally students can download the Electron App which allows them to run their programs locally to help reduce load on the backend server, however requires additional jdk installation and set JAVA_HOME and PATH=%JAVA_HOME%/bin variables.
All projects require a installation of NodeJS.
Install packages via:
npm install
Create a .env file with JWT_KEY= and a random combination of letters in the backend folder.
Run the backend server in development with
nodemon server
or in production with
npm start
The backend requires a MongoDB installation. Start the server as a service on Linux with
service mongod start
or on windows with
mongod
You also have to create a \data\db folder to save the database into.
And of course the backend also requires a java JDK installation. The java command has to be available on the console.
Install packages via
npm install
Run the server with
npm start
Package the website for production (afterwards available in the \build\ folder) with
npm run build
Install packages via
npm install
npm start
Package the application for production (afterwards available in the \out\ folder) with
npm run make
The Electron App does not wrap a website itself. It still loads the frontend webpage from the specified URL, however intercepts certain HTTP Requests to the backend which are responsible for executing code and writing to console. The Electron App currently does not have an auto-updater for the java executor jar responsible for the custom code execution highlighting.
