Use yarn cli:test to run the CLI in the TEST environment. This will use the test DB and will likely run some code a bit differently than in prod/dev.

Creating new commands

CLI is defined using yargs.We use it to define hierarchical trees of commands which allows for better organization both for command definition and for using the CLI.

All commands are created in the commands directory. Commands should be defined using command modules.

Any top-level modules under commands will be assumed to be command modules. If you want to define a child command for a top-level command, then configure the top-level command to look for further child commands using .commandDir().

Then put those child command modules in a subdirectory that is named after the top level command. So if the top level command is "db", then all of its child commands should be put inside a "db" subfolder.

Example commands dir:

- commands
    - db
        - migrate.js
    - db.js

In this case, db.js is the command module for the top-level db command. And then inside the db folder there's a command module migrate.js for the migrate child command of db.

This results in 2 commands - db and db migrate.
