Bootstrap a full stack application with pre-configured: hosting, database, authentication, CI, CD, component library, state management, form utils.

This template tries to make as many opinionated choices as possible about the dev stack in order to quickly build a product that could sustain a significant amount of traffic/users.

For this template to work all you will need is a Firebase project. I recommend using their free tier to start off.

Tech Stack Choices:

create-react-app as the project's starting point, using the cra-template-pwa-typescript template, this includes:
- React
- Typescript
- cra's bundling capabilities
- Jest for testing
- PWA pre-configured
Firebase for Hosting, Database (Firestore) with offline mode enabled, and Authentication
Github Actions to automate tests and deploys
material-ui component library
recoil for state management
react-hook-form for building forms quickly
react-testing-library for writing tests

Getting Started

After starting your repo with this template you need to configure your Firebase project:

Make sure you have enabled all the Firebase services you wish to use in your project
Copy your firebase config located at Firebase Project > Project Settings > Firebase SDK snippet > Config
Paste the firebase config to src/firebase/firebase.ts for the respective environment
Set your Firebase Project as default at .firebaserc

Automate Deploys to Firebase hosting

CI tests are configured out of the box, but to enable deploys to Firebase do the following:

Create a Firebase Auth Token locally: yarn firebase login:ci
Add the Firebase token to Github as a secret called FIREBASE_TOKEN. You can add secrets at Github Project > Settings > Secrets.
Open the file .github/workflows/ci.yml and uncomment the lines 46-51

Every time a commit is pushed to github, Github will automatically run the CI tests; and every time there is a push to master, Github will deploy the new version to Firebase. See the ci workflow in .github/workflows/ci.yml for more details.

Development

In two separate terminal windows run the commands: yarn start:server and yarn start. The Firebase server is run as an emulator locally, which means that it won't use any quota of your Firebase project.

The Firestore object has been extended with Typescript to enforce a database schema whenever you use firebase to access your Database. The schema you define can be hooked up in src/models/FirestoreCollectionPaths.ts.

Testing

I recommend following the react-testing-library advice of writing tests that closely resemble the way your app is used. This means writing more integration tests where you render the whole app and test actual user functionalities.

You can find some functions to help with rendering the app and mocking Firestore collections in the /test-utils folder. Here is an example of a test:

import renderApp from '../test-utils/renderApp'
import { mockCollection } from '../test-utils/firebaseMocks'

test('display all pets', () => {
  mockCollection('pets', { id: 'test', name: 'Abc' })
  const view = renderApp()
  expect(view.getByText('Abc')).toBeInTheDocument()
})
