Quick Start

Prerequisites

  • Docker and Docker Compose
  • NocoDB instance with API access
  • NocoDB API token

Installation

  1. Get NocoDB API Token

    1. Login to your NocoDB instance
    2. Click user icon → Account SettingsAPI Tokens
    3. Create new token with read/write permissions
    4. Copy the token for the next step
  2. Configure Environment

    Edit the .env file with your NocoDB API and API Url:

    # NocoDB API Configuration
    NOCODB_API_URL=https://db.cmlite.org/api/v1
    NOCODB_API_TOKEN=your-api-token-here
    
    # These will be populated after running build-nocodb.sh
    NOCODB_VIEW_URL=
    NOCODB_LOGIN_SHEET=
    NOCODB_SETTINGS_SHEET=
    NOCODB_SHIFTS_SHEET=
    NOCODB_SHIFT_SIGNUPS_SHEET=

  3. Auto-Create Database Structure

    Run the build script to create required tables:

    chmod +x build-nocodb.sh
    ./build-nocodb.sh
    

    This creates five tables:

    • Locations - Main map data with geo-location, contact info, support levels
    • Login - User authentication (email, name, admin flag)
    • Settings - Admin configuration and QR codes
    • Shifts - Shift scheduling and management
    • Shift Signups - User shift registrations
  4. Get Table URLs

    After the script completes:

    1. Login to your NocoDB instance at https://db.cmlite.org
    2. Navigate to your project ("Map Viewer Project - TIMESTAMP")
    3. Copy the view URLs for each table from your browser address bar
    4. URLs should look like: https://db.cmlite.org/dashboard/#/nc/project-id/table-id
  5. Update Environment with URLs

    Edit your .env file and add the table URLs:

    NOCODB_VIEW_URL=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/m6g7bkzv7s1w2ur
    NOCODB_LOGIN_SHEET=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/mizyc64e4r7ppzh
    NOCODB_SETTINGS_SHEET=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/mix06f2mlep7gqb
    NOCODB_SHIFTS_SHEET=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/mkx0tex0iquus1u
    NOCODB_SHIFT_SIGNUPS_SHEET=https://db.cmlite.org/dashboard/#/nc/pnsalzrup2zqvz8/mi8jg1tn26mu8fj
    
  6. Build and Deploy

    Build the Docker image and start the application:

    # Build the Docker image
    docker-compose build
    
    # Start the application
    docker-compose up -d
    
  7. Verify Installation

Security Considerations

  • API tokens are kept server-side only
  • CORS is configured for security
  • Rate limiting prevents abuse
  • Input validation on all endpoints
  • Helmet.js for security headers

Troubleshooting

Locations not showing

  • Verify table has Geo-Location, latitude, and longitude columns
  • Check that coordinates are valid numbers
  • Ensure API token has read permissions

Cannot add locations

  • Verify API token has write permissions
  • Check browser console for errors
  • Ensure coordinates are within valid ranges

Connection errors

  • Verify NocoDB instance is accessible
  • Check API URL format
  • Confirm network connectivity

Build Script Issues

  • Ensure NocoDB instance is accessible
  • Verify API token has admin permissions
  • Check that the NocoDB database is clean (delete all bases before running)
