# Contributing to karma
## Getting Started
To get started follow `Building from source` section of the [README](README.md)
file.
## Git tags and branches
Every release tag name will follow `vX.Y.Z` naming scheme, example: `v0.1.0`.
All releases are tagged against the `master` branch.
## Commit messages
[Conventional Commits](https://www.conventionalcommits.org) format is required
for all commits.
## Testing changes
To run included tests and linters run:
make test
## Vendoring dependencies
[Go modules](https://github.com/golang/go/wiki/Modules) are used for managing
dependecies. After adding new or removing exitsting depenencies please run
go mod tidy
to update `go.mod` and `go.sum` files.
## Javascript & CSS assets
UI is written using [React](https://reactjs.org), follow user guide for
[create-react-app](https://github.com/facebook/create-react-app) to make
changes to the UI code.
Some UI tests are using [snapshots](https://jestjs.io/docs/en/snapshot-testing).
After making changes that affect how existing components are rendered please
run:
cd ui && npm test -- -u
to update all snapshots. Remember to commit those changes when making a pull
request.
## Running
To build and start `karma` from local branch see `Running` section of the
[README](README.md) file.
When working with assets (templates, stylesheets and javascript files) `DEBUG`
make variable can be set, which will recompile binary assets in debug mode,
meaning that files from disk will be read instead of compiled in assets.
See [go-bindata docs](https://github.com/jteeuwen/go-bindata#debug-vs-release-builds)
for details. Example:
make DEBUG=true run
make DEBUG=true run-docker
Note that this is not the same as enabling [debug mode](/README.md#debug) for
the [gin web framework](https://github.com/gin-gonic/gin) which is used
internally, but enabling `DEBUG` via this make variable will also enable gin
debug mode.
When running docker image via `make run-docker` with `DEBUG` make variable set
to `true` volume mapping will be added (in read-only mode), so that karma
instance running inside the docker can read asset files from the sources
directory.
