Contributing

This repo is setup so that all contributors follow Conventional Commits conventions when writing commit messages.

You will not be able to merge your PR without following these conventions.

Important:

  • Please ensure that you have read and understood the Contributing guidelines before creating a PR.
  • This project is currently focused on bug fixes, nit fixes, documentation, and tests.
  • We are NOT accepting pull requests for new features or refactor contributions at this time.

How to file a bug report.

To file a bug report, please head over to the issues tab of this repository, create a new issue and in the issue template please select bug report.

A short primer on conventional commit messages

Prefix your commit messages with:

  • For minor version bumps: feat: some commit message
  • For patches / fixes: fix: some commit message
  • For major bumps (note the !): fix!: a major / breaking change

Note

Keel is currently pre-release (semver < 1). Do not commit any major releases using conventional commits to bump the version to v1 until we have decided that this is the case

Development

Nix

We use nix to manage our development environment. To install nix on MacOS run:

$ curl -L https://nixos.org/nix/install | sh

Once you have nix installed you can start a nix shell by running nix-shell in the root of the repo. The first time you run this it will install all the required dependencies so might take a while to run, but subsequently should be fast. When developing in this repo always start by starting a nix-shell.

Docker

You also need Docker (for runnning Postgres) which needs to be installed separately. Once installed the Docker daemon needs to be running, which you can check by running:

$ docker ps

Installing project dependencies

Running make install will install project level dependencies.

Setting conventional commits git hook (Optional)

This repo follows conventional commits, which means commits must be written in a certain way. If you want you can run make setup-conventional-commits to install a pre-commit hook which will check your commit messages as you make them.

Running Go tests

To run tests first make sure you have running Postgres using Docker:

docker compose up -d

Then use make test to run the tests.

# run all tests
$ make test

# run all test in the schema package (and all sub-packages)
$ make test PACKAGES=./schema/...

# A specific test from the integration package
$ make test PACKAGES=./integration RUN=TestIntegration/built_in_actions

Running JS tests

There are units tests in each of the JS packages in the ./packages directory. In each of these directories you can run pnpm run test but to run all the tests from all the packages you can use the make command make test-js.

Other useful make commands

  • make lint - lint Go code
  • make testdata - re-generate fixture data (check the diff carefully after doing this)
  • make proto - re-generate Go code in the ./proto package (run this after changing the .proto file)

Using the CLI in development

go run cmd/keel/main.go [cmd] [args]

Configuring a private key in development

The -private-key-path argument on the run command lets you pass in the path to a file containing a private key in PEM format. This may be useful if you need to perform development or testing with signed tokens.

go run cmd/keel/main.go run -private-key-path private-key.pem

You can generate a private key in PEM with openssl genrsa -out private-key.pem 2048 or using some online RSA key generator.

Building from source

You can build the CLI by running:

make build

To then use the built CLI binary you can run:

./bin/keel validate -f ...

Testing

Keel has a built-in testing framework that allows you to test the functionality of the Keel runtime end-to-end.

Complete documentation and examples for the @teamkeel/testing package can be found here.

Generating new schema test cases

There is a handy helper script to generate the relevant test case files if you'd like to write a new test case for something in the schema / validation rules:

sh ./scripts/new-test-case.sh test_case_name

This will generate:

  • A blank schema.keel file
  • An errors.json file where you can assert what errors you are expecting

Updating test cases

If you have made a change to error message copy, then you can run make testdata and all of the test case JSON files will be updated to the latest copy.

A note on test cases

Naming convention for test cases should describe the units you are testing in a hierarchical manner. Test cases covering validations should begin with validation_ for example, and subsequent fragments should describe which validation is being tested.

If a test case is complex, or the name itself doesn't adequately describe what it is testing, then either reconsider the naming, or consider adding a description.md file into the directory where the test case lives to provide more colour.
