Set up the database with other environments variables

Tips for install environment

Rust: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Important

Environment need: Rust >= 1.7.0, Node.js >= 18, Postgres >= 15

  1. Set environment variables into .env under the root directory

    KEY VALUE
    DATABASE_URL The database connection string
    REDIS_URL The redis connection string
    SECRET_TOKEN The key for session management

    You can use openssl rand -hex 32 to generate a random string for SECRET_TOKEN. Then run cp .env packages/backend/.env to copy the .env file to the backend directory.

  2. Init the database schema

    git clone https://github.com/AprilNEA/next-online-judge.git
& cd next-online-judge
& npm install -g prisma # pnpm or yarn, -g(--global) is optional
& prisma db push

  3. Run the backend server

    cd packages/backend
& cargo build --release
& cargo run --release
