chore(CRWA): convert to ESM #8159

jtoar · 2023-04-28T05:52:01Z

Edit: I've since added a .babelrc.js file for testing in a separate PR so the reasons for this PR detailed above aren't as valid. This package being a suitable build-tool playground is still pretty valid though.

I want to add more unit tests to CRWA, but since I've removed Babel from the equation, I've also removed Jest. I could add back the .babelrc.js file, but CRWA is a really nice package to try things out in since its 1) a binary like the CLI, not a library (so it's never imported from) and 2) uses very few other @redwoodjs/* as dependencies.

So I want to try out writing tests using the new node test runner, and to do that in a nice way, this package needs to be ESM so that I can just import the functions straight from src.

I manually published the changes in this PR under a different package name (and then deleted that pacakge) just to try it out, and it worked using both yarn 1 and yarn 3. After merge we can confirm again via canary, then I could get started on more unit tests.

esbuild sets NODE_ENV to production if minify is true, and here it is. See https://esbuild.github.io/api/#platform. (But more generally, I'm sure NODE_ENV really does anything here.)

To use require now, we'd have to create it using createRequire.

I thought snapshots were added to Node's test runner (or assert module), but I couldn't find them, so maybe I misread or they've been pulled out since

Seems like they were added here, but I can't find any docs on them: nodejs/node#44095

This comment here hints that it was removed, but still can't find the commit: nodejs/node#47392 (comment)

I tried yarn node --test at first, but when we run yarn test from the root, this command fails because it's fed bad options (jest related ones, like colors and maxWorkers). Something to figure out, but for now this works

I changed the esbuild logLevel to info from it's default of warning. Docs here https://esbuild.github.io/api/#log-level but I like info more as it's the default value when used with the cli and it shows at least a little success message when running yarn build from within the package.

I set --test-reporter spec because I was getting the tap reporter on my vscode terminal. I don't really think it'll make that much difference to switch it as we're not passing these test logs into anything programmatic?

We can tidy up things like the yarn test command later as things evolve and become clearer. I don't think it holds this back.

This was interesting to me, so I did some digging.
It's still experimental even in Node 20: https://nodejs.org/docs/v20.0.0/api/esm.html#json-modules

It looks like it'll change syntax slightly before it fully ships (assert will change to with)
https://github.com/tc39/proposal-import-attributes
Scrolling to the very bottom there's an interesting "History" section. That section also mentions that compatibility with assert will probably remain even after the official syntax switches to with

TIL 🙂

jtoar · 2023-07-14T19:59:08Z

This was mostly an experiment; we learned a lot. This will still probably happen one way or another eventually (along with the rest of the packages) but this doesn't need to stay open at the moment.
