🙏 We would ❤️ for you to contribute to and help make it even better than it is today!
Start by installing all dependencies:
yarn
Run the tests:
yarn test
yarn e2e
Run the playground app:
yarn start
yarn build
To ensure consistency throughout the source code, keep these rules in mind as you are working:
- All features or bug fixes must be tested by one or more specs (unit-tests).
- All public API methods must be documented.
We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the changelog.
Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
The header is mandatory and the scope of the header is optional.
Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.
The footer should contain a closing reference to an issue if any.
Samples: (even more samples)
docs(changelog): update changelog to beta.5
fix(release): need to depend on latest rxjs and zone.js
The version in our package.json gets copied to the one we publish, and users need the latest of these.
