Write Documentation

grpc-web-proto-compile could always use more documentation, whether as part of the official grpc-web-proto-compile docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue on GitHub.

If you are proposing a feature:

  • Explain in detail how it would work.

  • Keep the scope as narrow as possible, to make it easier to implement.

  • Remember that this is a volunteer-driven open source project, so contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up grpc_web_proto_compile for local development.

  1. Fork the grpc_web_proto_compile repo on GitHub.

  2. Clone your fork locally:

    $ git clone
  3. Install development dependencies into a virtual development environment (assuming you have pipenv installed):

    $ cd grpc_web_proto_compile/
    $ pipenv install --dev
    $ invoke install-hooks
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you are ready to make changes. Remember to add tests to tests/ and make sure all existing tests pass:

    $ pytest                                    # Run all tests
    $ pytest tests/    # Run one specific test
    $ tox                                       # Run the tests for different python versions
  5. When you’re done making changes, run all pre commit steps to make sure your changes pass all checks:

    $ invoke pre-commit
  6. If you are done, commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  7. Submit a pull request through the GitHub website so your changes can be merged into the master.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.

  2. If the pull request adds functionality, the documentation (docs/) should be updated. Put your new functionality into a function with a docstring and add the feature to the list in README.rst.

  3. The pull request should work for python 3.5+. Check the build status of your pull request and make sure that all tests pass for all supported python versions.

Publishing (Maintainers only)

After merging the changes, tag your commits with a new version and push to GitHub:

$ bump2version (major | minor | patch)
$ git push --tags
