We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.
Contributions to this project must be accompanied by a Contributor License Agreement. You (or your employer) retain the copyright to your contribution, this simply gives us permission to use and redistribute your contributions as part of the project. Head over to https://cla.developers.google.com/ to see your current agreements on file or to sign a new one.
You generally only need to submit a CLA once, so if you've already submitted one (even if it was for a different project), you probably don't need to do it again.
One way to ensure that your PR will be accepted is to add functionality that has been requested in Github issues. If there is something you think is important and we're missing it but does not show up in Github issues, it would be good to file an issue there first so we can have the discussion before sending us a PR.
In general, we're trying to add functionality when driven by use-cases instead of adding functionality for the sake of parity with TensorFlow python. This will help us keep the bundle size smaller and have less to maintain especially as we add new backends.
When adding ops to the library and deciding whether to write a kernel implementation in backend.ts, be sure to check out the TensorFlow ops list here. This list shows the kernels available for the TensorFlow C API. To ensure that we can bind to this with node.js, we should ensure that our backend.ts interface matches ops in the TensorFlow C API.
All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose. Consult GitHub Help for more information on using pull requests.
We require unit tests for most code, instructions for running our unit test suites are in the documentation.
