Install & Run

Dependencies:

• node 16.x
• python 3.8
• poetry

Run:

• npm install
• npm start
• visit http://localhost:5000/

To use an API key, put it in server/secrets.py or as an environment variable MBTA_V3_API_KEY

Linting

To lint frontend and backend code, run npm run lint in the root directory

To lint just frontend code, run npm run lint-frontend

To lint just backend code, run npm run lint-backend

Server Deployment

Additional requirements:

• nginx

Nginx serves as a reverse-proxy for the app running on localhost:5001. The Flask app is run under gunicorn and controlled by systemd, which will restart after failure or reboot automatically.

For a deploy on AWS (fresh, or not)

1. Make sure AWS CLI is set up and working—i.e. aws cloudformation describe-stacks | wc -l should work.
2. Make sure these environment variables are set up in your shell (ask a Labs member for values if needed):

• TM_NTT_CERT_ARN (for production)
• TM_LABS_WILDCARD_CERT_ARN (for beta)

3. A key named transitmatters-ntt needs to be available in your AWS account and copied to ~/.ssh/transitmatters-ntt.pem.
4. Run cd devops && ./deploy.sh (add -p for production) to deploy.
5. You're all set! Visit:

• https://ntt-beta.labs.transitmatters.org for beta
• https://traintracker.transitmatters.org for production
