Flex Spot FF Website Code

This stack is built upon Remix, so if you have questions, the Remix documentation is your best bet.

What's in the stack

• Multi-region Fly app deployment with Docker
• Multi-region Fly PostgreSQL Cluster
• Healthcheck endpoint for Fly backups region fallbacks
• GitHub Actions for deploy on merge to production and staging environments
• Discord Authentication with oAuth2 with remix-auth
• Database ORM with Prisma
• Styling with Tailwind
• End-to-end testing with Cypress
• Local third party request mocking with MSW
• Unit testing with Vitest and Testing Library
• Code formatting with Prettier
• Linting with ESLint
• Static Types with TypeScript

Development

Initial Setup

• Install your NPM modules

  npm install

• Start the Postgres Database in Docker:

  npm run docker

  Note: The npm script will complete while Docker sets up the container in the background. Ensure that Docker has finished and your container is running before proceeding.

• Copy .env.example to .env, and update the following:

  • DATABASE_URL to remove the _test at the end, as that's used for the testing pipeline
  • DISCORD_CLIENT_ID: Go to discord.com/developers, create an application, and then under the OAuth2 tab in settings, use the client ID
  • DISCORD_SECRET: On the same page as above, use the client secret (you may need to reset yours)
  • SESSION_SECRET: Not required but does set a different string for encrypting

• While you're in the discord developer settings, you'll also want to set redirects to the following if you want to test Discord authentication

http://localhost:3000/auth/discord/callback

• Initial setup:

  npm run setup

• Load database dump if you have one.

cat NAME_OF_BACKUP_FILE | docker exec -i NAME_OF_DOCKER_CONTAINER psql -U postgres flexspotff

(you may need to drop/create the db if that gives you a bunch of errors, you can do this to solve it)

docker exec -i flexspotff-postgres-1 dropdb -U postgres flexspotff
docker exec -i flexspotff-postgres-1 createdb -U postgres flexspotff

• Run the first build:

  npm run build

• Start dev server:

  npm run dev

This starts your app in development mode, rebuilding assets on file changes.

If you'd prefer not to use Docker, you can also use Fly's Wireguard VPN to connect to a development database (or even your production database). You can find the instructions to set up Wireguard here, and the instructions for creating a development database here.

Deployment

We use GitHub Actions for continuous integration and deployment. Anything that gets into the main branch will be deployed to production after running tests/build/etc. Anything in the dev branch will be deployed to staging.

Testing

Cypress

We use Cypress for our End-to-End tests in this project. You'll find those in the cypress directory. As you make changes, add to an existing file or create a new file in the cypress/e2e directory to test your changes.

We use @testing-library/cypress for selecting elements on the page semantically.

To run these tests in development, run npm run test:e2e:dev which will start the dev server for the app as well as the Cypress client. Make sure the database is running in docker as described above.

We have a utility for testing authenticated features without having to go through the login flow:

cy.login();
// you are now logged in as a new user

We also have a utility to auto-delete the user at the end of your test. Just make sure to add this in each test file:

afterEach(() => {
  cy.cleanupUser();
});

That way, we can keep your local db clean and keep your tests isolated from one another.

Vitest

For lower level tests of utilities and individual components, we use vitest. We have DOM-specific assertion helpers via @testing-library/jest-dom.

Type Checking

This project uses TypeScript. It's recommended to get TypeScript set up for your editor to get a really great in-editor experience with type checking and auto-complete. To run type checking across the whole project, run npm run typecheck.

Linting

This project uses ESLint for linting. That is configured in .eslintrc.js.

Formatting

We use Prettier for auto-formatting in this project. It's recommended to install an editor plugin (like the VSCode Prettier plugin) to get auto-formatting on save. There's also a npm run format script you can run to format all files in the project.
