Allow creating custom cli commands

[hardfire]

I very often see myself creating the first user (or other db objects) using the blitz console. It would be pretty cool if we could create custom cli commands to do activities that are repeated often. I see this pattern being used extensively in laravel.

PS: apologies if this has already been discussed before, couldn't find that discussion.

Hey! Yeah we could add a blitz task command that make it easy to do this stuff.

Currently the best way is to write Typescript scripts that you run via ts-node via package.json scripts. Check out this comment on how to make it work with absolute paths.

Another great thing about blitz task (or similar) would be that we could start other processes without building out a separate TypeScript tool chain.

For instance, I would love to be able to start BullMQ workers using Blitz itself.

I also use blitz console for this kind of stuff, and would create a "scripts" folder with service functions that are easy to import and invoke.

// blitz console
await require('scripts/devUserCreator').create()

It's a little more clunky than a pure CLI solution, but you get type safety on the function arguments.

This is a good way to handle it! I would imagine you can write tests for your scripts that are executed by the out-of-the-box jest setup too which is something else I want.

I would be happy as well if I could just pass a script to blitz console instead of having a new command.

For the same needs i created (need some time to finish the recipe) https://github.com/anolilab/blitzjs-cli-recipe/tree/feature/cli and https://github.com/anolilab/cerebro/tree/alpha

Im using a custom webpack config to search the commands like blitz for pages (preview https://discord.com/channels/802917734999523368/843912213399601192/875063361115656212)
