Armstrong

Armstrong is a React component library made by Rocketmakers written in Typescript and SCSS.

By default, Armstrong doesn't pre-compile its SCSS into CSS, allowing consuming projects to make use of its various SCSS variables and mixins.

Using Armstrong

Armstrong is installed using npm.

# This repo is currently @rocketmakers/armstrong-edge, writing docs as if deployed as main armstrong package
npm install @rocketmakers/armstrong
# or
yarn add @rocketmakers/armstrong

Then to use a component in your project

import { Button } from '@rocketmakers/armstrong';

const MyComponent: React.FC = () => {
  return (
    <div>
      <Button>I'm a button</Button>
    </div>
  );
};

See Storybook for a list of all available components

Working on Armstrong

Development

First cd into the root of the repo and run

asdf install
npm install

There are two options for working on Armstrong.

• We have a playground, which is just a really simple react app with no linting, which has the Armstrong module linked in using npm link
• We have a Storybook implementation which will pick up any files with the pattern *.stories.tsx

For the playground, run

npm start

# then in separate window from /module run
npm run start-sass

then go to localhost:3001

For Storybook, run

npm run storybook

# then in separate window from /module run
npm run start-sass

then go to localhost:6006

npm run start-sass will spin up a watcher which will watch all SASS files and rebuild them

For more information on using SASS, see SASS Concatenation in [SCSS](STORYBOOK LINK TODO)

Linting

Armstrong uses eslint, style-lint, and prettier for linting.

Packages for these are managed as dev dependencies in NPM, and configuration files can be found in module/

We recommend using the vscode plugins stylelint, eslint, and prettier to make errors show in vscode, and to allow auto fixing functionality.

Testing

Armstrong uses Jest for unit testing, @testing-library/react-hooks for hook testing, and Cypress via Storybook for component testing.

Packages for these are managed as dev dependencies in NPM, and configuration files can be found in module/ and in module/.jest and module/.cypress respectively.

Tests can be run using npm test for all tests, or npm test-jest and npm test-cypress respectively.

Due to the nature of the codebase it is not currently possible to use custom commands in Cypress.

Process

Please work in feature branches named feature/* branched from develop

When your work is ready, submit a pull request into develop and (if you're internal to Rocketmakers) post a link to your pull request in the #armstrong-dev slack channel for someone to review.

Github will run an Action to test linting and to see if Storybook builds before your branch can be merged.

Ensure Commitizen is installed for templating your commit messages.

Release process

When you are ready to release your work, open a pull request from develop into main named Release, and list all upcoming changes. Once all actions have passed, this can be merged in, where it'll be released automatically.

Armstrong uses Semantic release for automatic versioning and publishing based on Commitizen formatted messages from main.

The type of release will be worked out from all of the commit messages in your merge. So the highest of the following will dictate the version

fix: will be a patch 0.0.X
feat: will be minor 0.X.0
breaking: will be major X.0.0
chore: won't trigger a release

So basically, do your work on a branch feature/*, make sure all of your commit messages go through Commitizen, and when you're happy open a PR onto main.

When it gets approved and merged in, the release type will automatically be worked out based on the highest (breaking > feat > fix) of all the commits that are part of that merge and a tag and version will be published to npm automatically.

This release happens in a Github Action labelled release. Logs can be found here

Once a release is complete, please post a cursory message in the #armstrong Slack channel with a list of changes.
