Bazel is a large project and making a change to the Bazel source code can be difficult.
You can contribute to the Bazel ecosystem by:
- Helping rules maintainers by contributing pull requests.
- Creating new rules and open-sourcing them.
- Contributing to Bazel-related tools, for example, migration tools.
- Improving Bazel integration with other IDEs and tools.
The most helpful contributions fix bugs or add features (as opposed to stylistic, refactoring, or "cleanup" changes). Your change should include tests and documentation, keeping in mind backward-compatibility, portability, and the impact on memory usage and performance.
