Installation Guide (Step-by-Step)

Step 1: Install nvm (Node Version Manager)

nvm lets you install and switch between different Node.js versions.

On macOS/Linux, open Terminal and run:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

After it finishes, close and reopen your terminal, then verify it worked:

nvm --version

You should see a version number like 0.40.1.

Troubleshooting: If nvm: command not found, run this and try again:

source ~/.bashrc

Or if you use zsh (default on newer Macs):

source ~/.zshrc

Step 2: Install Node.js 22

nvm install 22

Verify it installed correctly:

node --version

You should see v22.x.x (e.g., v22.21.1).

Step 3: Clone the Repository

git clone https://github.com/avantifellows/af_lms.git
cd af_lms

Step 4: Use the Correct Node Version

The project includes a .nvmrc file that specifies the Node version. Run:

nvm use

You should see: Now using node v22.x.x

Step 5: Install Dependencies

npm install

This will download all required packages. Wait for it to complete.

Step 6: Set Up Environment Variables

Copy the example file:

cp .env.example .env.local

Open .env.local in a text editor and fill in the values. Ask your team lead for the actual credentials:

# Database (get these from your team lead)
DATABASE_HOST=your-db-host
DATABASE_PORT=1357
DATABASE_USER=postgres
DATABASE_PASSWORD=your-db-password
DATABASE_NAME=your-db-name

# DB Service (get these from your team lead)
DB_SERVICE_URL=https://staging-db.avantifellows.org/api
DB_SERVICE_TOKEN=your-db-service-token

# NextAuth
NEXTAUTH_URL=http://localhost:3000
NEXTAUTH_SECRET=generate-a-random-string

# Google OAuth (get these from your team lead)
GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret

To generate NEXTAUTH_SECRET, run:

openssl rand -base64 32

Copy the output and paste it as the value.

Step 7: Set Up the Database (First Time Only)

npm run db:setup-permissions

This creates the permissions table. It's safe to run multiple times.

Step 8: Start the Development Server

npm run dev

Open your browser and go to: http://localhost:3000

Common Issues

"nvm: command not found"

Close and reopen your terminal, or run source ~/.zshrc (Mac) or source ~/.bashrc (Linux).

"Node version X is not installed"

Run nvm install 22 then nvm use.

"Cannot connect to database"

Check that your .env.local has the correct database credentials. Make sure your IP is whitelisted if connecting to a remote database.

Build fails with Node version error

Make sure you ran nvm use before npm run dev or npm run build.

Daily Development Workflow

Each time you open a new terminal to work on this project:

cd af_lms        # Go to the project folder
nvm use          # Switch to the correct Node version
npm run dev      # Start the development server

Scripts

Command	Description
npm run dev	Start development server
npm run build	Build for production
npm run start	Start production server
npm run lint	Run ESLint
npm run db:setup-permissions	Create/update permissions table

Architecture Notes

Database Access Pattern

This app uses a hybrid approach:

• Reads: Direct PostgreSQL connection (for performance)
• Writes: Via DB Service API (maintains data consistency)

This is intentional technical debt for rapid development. The DB Service is Avanti Fellows' canonical data layer.

Permission System

Permissions are stored in user_permission table:

• email: User's email (unique)
• level: School scope level (1-3)
• school_codes: Array of school codes (for level 1)
• regions: Array of region names (for level 2)
• read_only: Boolean for view-only access

Adding New Admin Users

1. Go to /admin/users (requires admin access)
2. Click "Add User"
3. Enter email and select permission level
4. For Region/School access, select the specific regions or schools
5. Optionally enable "Read-only access"

Or manually via database:

INSERT INTO user_permission (email, level, school_codes, regions, read_only)
VALUES ('user@example.com', 3, NULL, NULL, false);

Deployment

The app is deployed on AWS Amplify. Pushes to main trigger automatic deployments via GitHub Actions.

Environment	URL
Production	https://lms.avantifellows.org

See AMPLIFY_DEPLOYMENT.md for full deployment setup and instructions.

Environment Variables

Environment variables are managed via GitHub Secrets and synced to Amplify by GitHub Actions. See .env.example for the full list.

Google OAuth Setup

The Google OAuth client must have the authorized redirect URI:

https://lms.avantifellows.org/api/auth/callback/google

Configure this in Google Cloud Console.
