Development

• yarn dev:mac_os will serve badge renders to http://localhost:3000/:campaign_id/:user_id.png using the default Chrome path on MacOS. For other paths run env CHROME_PATH=<path_to_chrome> nodemon local.js

Deploy

We deploy to a lambda of architecture amd64

Build node_modules

SSH into EC2 instance of architecture amd64 and do:

1. Clone and cd into this repository
2. rm -rf node_modules
3. npm install --only=prod
4. zip -r index index.js render.js node_modules (make sure there isn't any extra stuff in node_modules

Now back on your local machine:

1. scp the .zip that was just created locally
2. Upload the .zip to the Lambda web interface
3. (optional) extract the .zip locally so you can reuse node_modules and skip the EC2 step until package.json changes
