Getting Started

Prerequisites

• Docker and Docker Compose
• Git

Installation

1. Clone the repository

   git clone <repository-url>
   cd MerchantsOfHope-SupplyANdDemandPortal
   

2. Copy environment template

   cp .env.example .env
   

   The defaults support Docker-based development. Adjust values as needed for local tooling or deployment pipelines.

3. Start the application with Docker (recommended for parity) This single command builds the images, starts all services, runs database migrations, and seeds the database with sample data.

   docker-compose up --build
   

4. Access the application

   • Frontend: http://localhost:12000
   • Backend API: http://localhost:3001 (from host) or http://merchantsofhope-supplyanddemandportal-backend:3001 (from other containers)
   • Database: merchantsofhope-supplyanddemandportal-database:5432 (inside Docker network)

Environment Variables

The backend now derives its DATABASE_URL automatically when the POSTGRES_* variables are present. The following additional variables are available:

# Request throttling defaults (~100 requests / 15 minutes)
RATE_LIMIT_WINDOW_MS=900000
RATE_LIMIT_MAX=100

# Uploads directory (overridable if you mount elsewhere)
UPLOAD_DIR=uploads/resumes

# Optional entrypoint controls
RUN_MIGRATIONS=true
RUN_SEED=false

# Database pool and wait tuning (milliseconds)
DB_POOL_MAX=10
DB_POOL_IDLE_MS=30000
DB_POOL_CONNECTION_TIMEOUT_MS=5000
DB_WAIT_TIMEOUT_MS=60000

Set POSTGRES_PASSWORD and JWT_SECRET before launching the stack. See .env.example for the full list.

Demo Accounts

The application comes with pre-seeded demo accounts:

• Admin: admin@merchantsofhope.org / admin123
• Recruiter: recruiter@merchantsofhope.org / recruiter123
• Employer: employer@techcorp.com / employer123
• Candidate: candidate@example.com / candidate123

Testing

Quality Gates & Tests

npm run lint and npm test must pass in both the backend and frontend. By default, the backend Jest suite bootstraps a disposable Postgres instance via Docker (using docker-compose.test.yml), so Docker must be available on your workstation. To point the tests at an existing database (e.g., CI runners), set USE_DOCKER_TEST_DB=false and supply DATABASE_URL/POSTGRES_*.

Quick commands:

# Backend
cd backend
npm install
npm run lint
npm test -- --runInBand --coverage

# Frontend
cd frontend
npm install
npm run lint
npm test -- --watchAll=false --coverage

To mirror CI in one shot, run the helper script from the repository root:

./scripts/run-ci-tests.sh

The script executes linting followed by the backend and frontend test suites (each with coverage reporting). Coverage thresholds are enforced by Jest to guard against regressions. The helper waits for the ad-hoc PostgreSQL container, honours the backend entrypoint (which now blocks on database readiness, runs migrations, and optionally seeds), and then runs both suites with coverage thresholds enforced.

Continuous Integration

Gitea Actions configuration lives in .gitea/workflows/ci.yml. It:

• Runs backend and frontend unit tests on every push or pull request.
• Builds Docker images on pushes to the main branch, ready to publish to a registry (requires REGISTRY_* secrets).

See inline comments in the workflow for required secrets.

Deployment

Coolify

Follow docs/COOLIFY_DEPLOYMENT.md for guidance on connecting this repository to a Coolify environment, configuring secrets, and enabling automated deploys via Gitea CI.
