A2J - Kommunikationsplattform

Prerequisites

Node.js and Homebrew

We aim to use the current active LTS version of Node.js, which is V20 at the time of writing. There is a .tool-versions file to simplify setup using nodenv (install Node version by running nodenv install) or asdf (check and install used Node version by running asdf current).

Additionally we use Git Hooks that can be installed with Homebrew, please check if brew is available on your machine with brew -v command.

Dependencies

Install the project dependencies using npm.

npm install

Testing

For E2E and a11y testing with Playwright you will need to install the supported browsers:

npx playwright install

Git Hooks

For the provided Git hooks you will need to install lefthook (git hook manager) and talisman (secrets scanner) brew install lefthook talisman. Afterwards execute lefthook install to initialize the hooks or run lefthook run pre-commit before commiting new changes.

See lefthook.yml for more details and have a look at conventional commit messages.

Development

Configure .env variables

Copy the .env.example file and save it as .env within this projects root folder and define the needed environment variables. For example:

BASE_URL=http://localhost:3000

Local development

From your terminal:

npm run dev

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

Testing

The application has

• unit tests (using Jest)
• end-to-end tests (using Playwright)
• accessibility tests (using Playwright and Axe)

Test commands

• Run unit tests: npm test
• Run unit tests with watcher: npm test -- --watch
• Run E2E tests: npm run test:e2e
• Run A11y tests: npm run test:a11y

Code quality checks (linting & formatting)

The project uses ESLint for linting and Prettier. for formatting.

Commands

• Check formatting: npm run format:check
• Autofix formatting issues: npm run format:fix
• Check lint: npm run lint:check
• Autofix lint issues: npm run lint:fix
• Check style (formatting & linting): npm run style:check
• Autofix style issues (formatting & linting): npm run style:fix

Deployment

Build and run the app in production mode:

npm run build
npm start

Docker

The project includes a Dockerfile to create a Docker Image for the project.

You can build the Docker Image using

docker build -t a2j-kommunikationsplattform .

and then start it using

docker run -d -p 3000:3000 --name a2j-kommunikationsplattform a2j-kommunikationsplattform

The website is then available under http://localhost:3000

If you want to include any additional files during the build that are not in the app directories you need to add them to the .dockerignore file.

The .github/workflows/pipeline.yml GitHub Action includes a build-and-push-image job to build the Docker Image and push it to GitHub Packages.

DIY

If you're familiar with deploying node applications, the built-in Remix app server is production-ready.

Make sure to deploy the output of npm run build

• build/

Architecture Decision Records

The docs/adr directory contains architecture decisions. For adding new records the adr-tools command-line tool is useful but not strictly necessary:

brew install adr-tools
