This project contains 2 main parts:

• Lambda Functions (back end)
• a web application that queries the Algolia index and calls the lambda functions (front end)

All decisions related to this project are located in the ADR folder.

A complete stack of AntiCovid is composed of the following:

• A PostgreSQL database, which contains views of data to expose;
• Firebase Functions, that are used to push data from the PostgreSQL database to the Algolia index, or register a new subscription, or send an email when new trials match a subscription.
• An Algolia index, which is used as database and search engine for the application;
• A Firestore database that is used to store search suggestions and subscriptions.
• Google Cloud Pub/sub, used by functions to communicated with each other.
• A React front-end application, visitor facing, deployed on Firebase Hosting.

If you're not part of Inato, you'll need an Algolia account and a Postgres database with a table filled with required data to be able to fully run all the components of this project.

To build and run on localhost:3000

yarn start

To configure the indices your local app connects to, modify src/config/config.json

To run integration tests use

yarn test

from the root folder for the app tests, and from the functions/ folder for the functions tests.

We use Cypress to run e2e tests. Locally, you can open a cypress window and select the tests to run:

yarn e2e:dev

To run all e2e tests (CI for ex):

yarn e2e

Everything is deployed to Firebase.
