• It is a clone of Leetcode Ide

Version-1

Understanding Folder Structure [ This was version1 and is moved to another branch ]

• There are two folders client for frontend backend for backend.

• In client folder:

  • app.js is the Home page or main page.
  • components folder have all the components :
    • CodeEditor - The editor for writing codes [ Multiple themes/Language support]
    • CodeInput - For taking user input same as in leetcode ide
    • CodeOutput - For showing the result of the code
    • Navbar - It is the basic navbar above editor for providing features of Run Code and theme selection etc.
  • lib folder contains a file defineTheme.js which is used to define a new theme for the editor
  • boilerCodes contains the initial codes for all the languages in the editor

• In backend folder:

  • index.js is the main file of execution.
  • A post request /run is created using Express inside it which is the main request of this project.
  • It gets the user-code,code-language and user-input as request.
  • Then it creates two separate files one for code [like 'a.cpp','a.py','a.js'] and other file for input ['input.txt'] using generateCodeFile.js
  • Now Node child process [ exec ] is used to compile the compiled language [cpp] or interpret the interpreted languages [py,js] using executeCodeFile.js
  • Return the error or result as promise to frontend.

This was all about the folder structure and working of the files.

For Deploying the project

• As I was not getting any idea how to create a file on mongodb database and then compile that file.
• I researched a lot about it and then I found some online compiler api's that gives support to all languages.
• I will be implementing that in my project and then will deploy it.

Version -2

• I have used RapidAPI and JUDGE0 for compiling the codes.

• Boiler Code for all languages.
• Facility to save code snippets with some keywords and accessing it
• Saving the code in system.
• Save current code in localstorage to avoid loss of code on reload.

• [] Authentication
• [] Settings, snippets for each user
• [] Many more things

• Go to Judge0-rapidApi and signup if needed
• Create a .env file with given keys and values [These values can be taken from above link]
