plz cli

Toolkit for generating, building & testing packages.

Specifically, it consolidates:

1. Generating new packages & apps.
2. Configuring build pipelines. eg. Webpack, Babel
3. Configuring and running unit & integration tests. eg. Jest + Babel
4. Starting a development server for UI components & Apps.

Usage

$ plz <command> [options]

# CLI help
$ plz help

# Usage for individual commands
$ plz help <command>

Commands

create <name> [--root-path=<pwd>] [--type=<react-component>]

Generates a package called @rexsoftware/<name>.

Uses scaffold templates found in templates/. Defaults to react-component template.

Can create:

• react-component
• react-app
• module

test [options]

Starts a test runner in current directory.

Uses the jest test runner.

stories

Rationale

The CLI is largely a facade around other tools:

• nwb, by insin (module bundler)
• jest, by facebook (test runner)
• storybook, by kadira (ui testing environment)

But, by creating a facade around these tools we can:

• Avoid forcing developer to learn & remember individual tools until they're required to.
• Replace the tools without changing the front-facing API of plz cli
• Optimise package's output over time, without costly refactors in every package

Developing

Modifying dependencies!

Dependencies are managed are the root of the project by lerna.

1. Add/remove a dependency in package.json manually
2. In the root of heidi, run yarn install-deps

Structure

Start by looking into index.js.

The bulk of logic are in the individal command files, in src/commands/. Commands can follow different code paths for different package types.

Configuration for the internal tools can be found under src/configs/.

Testing

# Watch for changes, rerunning tests
$ yarn test

# Run watch once
$ yarn test:once
