Development

For an optimal developer experience, it is recommended to install Nix and direnv.

Alternatively, install Go on your computer then run make deps to install the rest of the dependencies.

Make sure Docker is installed with Compose and Buildx.

Run project dependencies:

make up

Build a binary:

make build

Run the test suite:

make test
make test-e2e

Run linters:

make lint # pass -j option to run them in parallel

Some linter violations can automatically be fixed:

make fmt

Build artifacts locally:

make artifacts

Once you are done either stop or tear down dependencies:

make stop

# OR

make down
