Architecture

The diagram is provided by cdk-dia.

Development

You need to have valid AWS credentials to run dev in live reload mode

• Start dev server:

yarn dev

This starts your app in development mode, which hot reloads changes to AWS.

Relevant code

This is a pretty simple note-taking app, but it's a good example of how you can build a full stack app with aws-cdk and Remix. The main functionality is creating users, logging in and out, and creating and deleting notes.

• creating users, and logging in and out ./app/models/user.server.ts
• user sessions, and verifying them ./app/session.server.ts
• creating, and deleting notes ./app/models/note.server.ts

Deployment

Deployments to AWS are managed by the AWS CDK.

yarn cdk deploy

GitHub Actions

The github actions are based on those blogged here:

Secure AWS-CDK deployments with GitHub Actions

Testing

Cypress (WIP)

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.
