Pull Requests

We welcome contributions via pull requests! Here are some guidelines to help you get started:

Fork the repository and clone it to your local machine.
Create a new branch for your changes: git checkout -b my-new-feature.
Ensure you have the required dependencies installed by running: pnpm install (assuming pnpm version 8.x).
Make your desired changes and, if applicable, include tests to validate your modifications.
Run the following commands to ensure the integrity of your changes:
- pnpm check: Verify that the code compiles.
- pnpm test: Execute the tests.
- pnpm circular: Confirm there are no circular imports.
- pnpm lint: Check for code style adherence (if you happen to encounter any errors during this process, you can use pnpm lint-fix to automatically fix some of these style issues).
- pnpm dtslint: Run type-level tests.
- pnpm docgen: Update the automatically generated documentation.
Create a changeset for your changes: before committing your changes, create a changeset to document the modifications. This helps in tracking and communicating the changes effectively. To create a changeset, run the following command: pnpm changeset. Always choose the patch option when prompted (please note that we are currently in pre-release mode).
Commit your changes: after creating the changeset, commit your changes with a descriptive commit message: git commit -am 'Add some feature'.
Push your changes to your fork: git push origin my-new-feature.
Open a pull request against our main branch.

Pull Request Guidelines

Please make sure your changes are consistent with the project's existing style and conventions.
Please write clear commit messages and include a summary of your changes in the pull request description.
Please make sure all tests pass and add new tests as necessary.
