feat: Lifecycle hooks

[ieedan]

Now you can hook into the jsrepo lifecycle using the before and after hooks. Run codemods, formatters, linters, you name it.

You just configure the hooks in your config like so:

import { defineConfig } from "jsrepo";

export default defineConfig({
	hooks: {
		before: ({ command }) => {
			console.log(`Running ${command}...`);
		},
		after: "echo done",
	},
});

You can run arbitrary code or commands by setting them up in your config.

Any before hooks that fail will cause the user to be prompted on whether or not they wish to continue. After hooks will simply log a warning and continue.

It's possible we will introduce more commands in the future but I think for now before and after are a good start...

FAQ

Where does this leave transforms?

Transforms are still the preferred way to modify your code as it's added to your project they run before the code is actually added to your project. Because of this we can show diffs with formatted code when using transforms like oxfmt, biome, and prettier. That being said hooks will be extremely nice for those cases where a transform plugin doesn't yet exist for your use case.

Side note: Pretty impressed with this. This is 100% composer-1.5 after creating a plan with Opus. Not one shot unfortunately but I would say this is pretty much exactly what I would've wrote.
