How to deploy

Prerequisitions

• Install node_modules using npm install

• Get your Firebase service account key.
  Create Firebase project, go to settings, Service accounts. Generate a private key and put it under private/firebase-service-account-key.json

• Set Firebase DB url as FIREBASE_DB_URL env variable. To acquire Firebase DB url, go to Firebase project console, Database, then choose "Realtime database" and copy the url provided.

Run locally

To run the server locally, use npm run start.
This will run the server on http://localhost:3000.

First time deploy

To create a new lambda function in a selected region, use the following command:

claudia create --handler lambda.handler --deploy-proxy-api --region eu-central-1

Where eu-central-1 is your selected region.

Push new code to existing lambda

After you've used claudia create and have claudia.json file generated, you can use nmp run deploy
