Setup and development

First-time setup

Make sure you have the following installed:

  • Node (at least the latest LTS)
  • Yarn (at least 1.0)

Its automatically installed in the Docker container. Developing inside a Container.

Then update the following files to suit your application:

  • src/app.config.json (provides metadata about your app)
  • .circleci/config.yml (assuming you want to automatically deploy to production with continuous integration)

Installation

# Install dependencies from package.json
yarn install

Dev server

Note: If you're on Linux and see an ENOSPC error when running the commands below, you must increase the number of available file watchers.

# Launch the dev server
yarn dev

# Launch the dev server and automatically open it in
# your default browser when ready
yarn dev --open

# Launch the dev server with the Cypress client for
# test-driven development in a friendly interface
yarn test:e2e:dev

Developing with the production API

By default, dev and tests filter requests through the mock API in tests/mock-api. To test directly against a local/live API instead, run dev and test command with the API_BASE_URL environment variable set. For example:

# To develop against a local backend server
API_BASE_URL=http://localhost:3000 yarn dev

# To test and develop against a production server
API_BASE_URL=https://example.io yarn dev:e2e

Aliases

To simplify referencing local modules and refactoring, you can set aliases to be shared between dev and unit tests in aliases.config.js. As a convention, this project uses an @ prefix to denote aliases.

Globals

Base components

Base components (a.k.a. presentational, dumb, or pure components) that apply app-specific styling and conventions should all begin with the _base- prefix. Since these components are typically used in place of raw HTML element (and thus used as frequently), they're automatically globally registered for convenience. This means you don't have to import and locally register them to use them in templates.

Docker (optional)

If you'd prefer to use Docker for development, it's recommended to install and run Docker Desktop. Once the app is started, you'll be able to run commands like:

# Build and run a containerized version of your app in the background
docker-compose up --detach

Once your container has started, you can run any script from package.json inside the container by prefixing the command with yarn docker instead of just yarn. For example:

# Install dependencies in the container
yarn docker install

# Run the dev environment in the container
yarn docker dev

# Run tests in the container
yarn docker test

To list your containers and their statuses, you can run:

docker-compose ps

To stop your running containers, run:

docker-compose stop

If ever update the following files:

  • .dockerignore
  • docker-compose.yml
  • docker-dev.dockerfile

Then you'll want to stop and remove all containers, networks, volumes, and images created for your app with:

docker-compose down --volumes --rmi all --remove-orphans

This command can also be useful in case something goes wrong with a container and you'd like to start over. All containers, networks, volumes, and images defined in docker-compose.yml will be rebuilt the next time you run docker-compose up.

See the docs for Docker and Docker Compose for more information on how to use and configure Docker tooling.
