Hacking on the Registry

The registry needs a persistent store, and for local development we have a docker image with PostgreSQL setup to automatically create tables and users. To make things super simple, in the hack/ directory there is a docker-compose file already configured to setup the basic containers needed for local developemnt. Simply run

$ docker-compose up

in the hack/ directory to get them going. Also in the hack/ directory is a script for connecting to the MySQL that is running in the docker container, for ease of poking around.

$ compose up

Also in the hack/ directory are some sample configuration files. By default, the included run-dev.sh script will use the hack/configs/registry-local.postgres.json file, which works well with the included docker-compose.yaml file.

Hacking on the Proxy

The proxy component is more simple than the registry in that it does not connect to anything (other than the registry itself). It does however maintain its data-store of downloaded modules on disk, and by default it saves modules in the /tmp directory.
