This bootstraps ESM loaders in the ShadowRealm with ShadowRealm.prototype.importValue as its entry point and enables loading ESM and CJS modules in the ShadowRealm. The module is imported without a parent URL and resolved with the current process's working directory.

Rebased on the tip of the main branch and removed dependencies on #48510 (with known limitation on memory leaks). Marking as ready to be reviewed. This PR would unblock the verification of built-in modules support in the shadow realm.

We’re working on eventually removing the CommonJS loader, leaving only the ESM loader as the single module loader (as it can load both CommonJS and ESM code). Is it possible to refactor this so that ShadowRealm always loads everything only through the ESM loader? Then this part of things won’t need refactoring when the CommonJS loader goes away, and there would also be more uniformity in how modules are loaded within ShadowRealm.

@GeoffreyBooth The ShadowRealm interface only exposes ESM ShadowRealm.prototype.importValue(speficier) and no CJS equivalent. The test case in the PR merely shows that the modules imported in the ShadowRealm can create a require function, just like what we can do in the principal realm.

Are you suggesting this PR didn't load modules in ShadowRealm.prototype.importValue(speficier) with the ESM loader? If so, could you share a hint of how I can fix that?

I was just responding to the PR description, “This bootstraps ESM and CJS module loaders in the ShadowRealm.” Did what you mean to say that it allows for loading ESM and CJS modules in the ShadowRealm?

I don’t really follow what a lot of the code in this PR does. If its only internal interactions with module loaders are through the ESM loader, then we’re good.

Yes, CJS support in ShadowRealm is enabled by ESM loaders. It seems that the PR description is misleading somehow, I've fixed the wording.

The module is imported without a parent URL and resolved with the current process’s working directory.

We had a similar situation with node:module register, of needing to resolve relative to process.cwd as an unfortunate default that we dislike but couldn’t find a better alternative for. We added a second parameter to register allowing the user to pass parentURL to resolve against, so that most usage would be like register('ts-node', import.meta.url). You might want to consider the same here.

Also please make sure that the string is interpreted as a file URL and not as a path, because import specifiers must be file URLs and you’re calling this API importValue. Then users can do things like realm.importValue(import.meta.resolve('./file.js'), 'foo').
