About the Project

This is a CodeVue - A Leetcode, CodeChief Inspired Platform designed to help developers practice coding challenges in multiple programming languages (JavaScript, Python, Java). The platform includes features such as:

• Problem Descriptions: Detailed problem descriptions, examples, constraints, and hints.
• Test Cases: Predefined test cases for each problem to validate solutions.
• Multi-Language Support: Write solutions in JavaScript, Python, or Java.
• Submission Tracking: View submission history, memory usage, runtime, and status (Accepted, Wrong Answer, etc.).

1. Problem Details

• Each problem includes:
  • Description
  • Examples with inputs, outputs, and explanations
  • Constraints
  • Editorial (hints and optimal solutions)

2. User Authentication

• Secure login and registration for tracking user progress and submissions.

3. Admin Panel

• Admins can add new problems, manage submissions.

Installation and Setup

Prerequisites

• Node.js (v16 or higher)
• npm or yarn
• PostgreSQL database
• Judge0 API

Steps to Run Locally

1. Clone the Repository

   git clone https://github.com/Aestheticsuraj234/chai-or-leetcode.git

   cd backend cd frontend

2. Install Dependencies

   npm install

3. Setup Prisma

   npx prisma init

• This will create a new prisma/ folder with a schema.prisma file inside, and also add a .env file at the root of your project.

• If you haven't installed Prisma yet, first install it with:

  npm install prisma --save-dev

• And if you also want the Prisma Client to query your database:

  npm install @prisma/client

• To start a local PostgreSQL container for development, run the following Docker command:

  docker run --name <databasename> -e POSTGRES_USER=<username> -e POSTGRES_PASSWORD=<password> -p 5432:5432 -d postgres

4. Set Up Environment Variables Create a .env file in the root directory and add the following variables:

   PORT =
   DATABASE_URL=
   JWT_SECRET=
   JUDGE0_API_URL=http://localhost:2358/ || http://localhost:<Your Judge0 Server Port>/ || Your Api link

5. Run the Development Server

   npm run dev
