Error: ENOENT: no such file or directory

[draylegend]

Which @angular/* package(s) are the source of the bug?

compiler, compiler-cli

Is this a regression?

Yes

Description

I'm trying to use elysia instead of express and the application is loading properly, but I encountered an error while building the app.

It seems the build is expecting a browser directory in the .angular/prerender-root path, which is missing.

Please provide a link to a minimal reproduction of the bug

The issue arises during the build process when static assets are missing, causing @elysiajs/static to fail if the directory does not exist.

To resolve this, you can either register the plugin when isMainModule(import.meta.url) returns true or implement a safety check to ensure the directory exists.
Here's a refined version of your note for clarity and precision:

Side note: I noticed that the AngularAppEngine is initialized for every request, which negatively impacts performance.

Consider instantiating it once and reusing the instance:

-  .get('/*', c => new AngularAppEngine().handle(c.request));
+  const appEngine = new AngularAppEngine();
+  .get('/*', c => appEngine.handle(c.request));
