Description

Node 20 has added support for require() to load ESM files, though only ESM files that don't use top-level await.

This breaks the angular CLI loading those modules, since it now fails with with ERR_REQUIRE_ASYNC_MODULE rather than ERR_REQUIRE_ESM

angular-cli/packages/angular_devkit/architect/node/node-modules-architect-host.ts

Lines 322 to 335 in 259f8c5

	// The file could be either CommonJS or ESM.
	// CommonJS is tried first then ESM if loading fails.
	try {
	return localRequire(builderPath);
	} catch (e) {
	if ((e as NodeJS.ErrnoException).code === 'ERR_REQUIRE_ESM') {
	// Load the ESM configuration file using the TypeScript dynamic import workaround.
	// Once TypeScript provides support for keeping the dynamic import this workaround can be
	// changed to a direct dynamic import.
	return (await loadEsmModule<{ default: unknown }>(pathToFileURL(builderPath))).default;
	}
	throw e;
	}

Minimal Reproduction

Have a builder that uses top-level await, try to use the builder

Exception or Error

Error: unexpected top-level await at file:///home/jenkins/workspace/<redacted>
     esbuild = await import("esbuild");
               ^

An unhandled exception occurred: require() cannot be used on an ESM graph with top-level await. Use import() instead. To see where the top-level await comes from, use --experimental-print-required-tla.
