supabase-init

Initialize configurations for Supabase local development.

A supabase/config.toml file is created in your current working directory. This configuration is specific to each local project.

You may override the directory path by specifying the SUPABASE_WORKDIR environment variable or --workdir flag.

In addition to config.toml, the supabase directory may also contain other Supabase objects, such as migrations, functions, tests, etc.
