TransitMatters Shutdown Tracker

This is the repository for the TransitMatters Shutdown Tracker. Client code is written in Typescript with React and vite, and the minimal backend is written in Python with Chalice.

Requirements to develop locally

• node 22.x and npm 10+ required
  • With nvm installed, use nvm install && nvm use
  • verify with node -v
• Python 3.12 with recent poetry (1.6.0 or later)
  • Verify with python --version && poetry --version
  • poetry self update to update poetry
  • If using pyenv, pyenv install 3.12.0

Development Instructions

1. In the root directory, run npm install to install all frontend and backend dependencies
2. Run npm start to start both the Vite development server and the Python backend at the same time.
   1. npm run dev to just run the Vite development server
   2. npm run start-python to just run the Chalice backend server
3. Navigate to http://localhost:3000 (or the url provided after running npm start)

Deployment Instructions

1. Configure AWS CLI 1.x or 2.x with your AWS access key ID and secret under the profile name transitmatters.
2. Configure shell environment variables for AWS ACM domain certificates.
   • TM_LABS_WILDCARD_CERT_ARN
   • (You may also need to set AWS_DEFAULT_REGION in your shell to us-east-1. Maybe not! We're not sure.)
   • DD_API_KEY (Datadog API key, needed to deploy to TransitMatters stack in prod)
3. Execute ./deploy.sh.

Additional notes:

• If you're on a platform with a non-GNU sed, deploy.sh might fail. On macOS, this is fixed by brew install gnu-sed and adding it to your PATH.
• If you get an unexplained error, check the CloudFormation stack status in AWS Console. Good luck!

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

VSCode

If you're using VSCode, .vscode contains a based default workspace setup. It also includes recommended extentions that will improve the dev experience. This config is meant to be as small as possible to enable an "out of the box" easy experience for handling eslint.
