1. Initial Commit - a boiler plate code and POC to realize the concept of context
sensitive help
2. Frontend code written in ReactJS
3. Backend code written in Java, Spring Boot Framework
4. Frontend Start:
pre-requisites : node, npm
npm run dev ==> to start the frontend vite server
5. Backend Start:
pre-requisites : java, mvn
mvn spring-boot:run ==> to start the backend server
6. Visit http://localhost:5173/ for basic demo of help, press F1 in textboxes
7. Visit http://localhost:5173/editor and enter "admin123" to add/modify texts.
Happy Coding !!!
Thank you,
Bhargava.
