Deno.bundle uses cache

[amatiasq]

I'm creating a script:

deno --allow-read=. --allow-net https://amatiasq.com/deno/web.ts my-script.ts

That watches the file system and bundles my-script.ts into a frontend-ready file.

The issue is that when a file system event is detected Deno.bundle bundles again from cache. Making the tool unusable.

I wasn't able to find a way to clear cache, I tried starting a process deno bundle my-script.ts but that doesn't allow me to pass a custom tsconfig to add lib: ["DOM"].

As a workaround, maybe you could run deno cache before deno bundle, each time the watcher triggers.

@sholladay good idea!

I tried this before the bundle:

  await Deno.run({
    cmd: ['deno', 'cache', file],
  }).status();

And now suddenly Deno.bundle is ignoring the lib parameter:

  const [diagnostics, content] = await Deno.bundle(file, undefined, {
    lib: ['dom'],
  });

Since it throws:

error: TS2584 [ERROR]: Cannot find name 'document'. Do you need to change your target library? Try changing the `lib` compiler option to include 'dom'.
const potato = document.querySelector('canvas');

That same error doesn't happen if I comment the deno cache execution 😮

Same problem as in #4743 and #5253
