bun build linked sourcemap option

[sk337]

What is the problem this feature would solve?

source map external does not link to the source map preventing browser from automatically loading them

What is the feature you are proposing to solve the problem?

add an option to the source map flag named linked the will add a source mapping comment like this
//# sourceMappingURL=index.js.map

What alternatives have you considered?

I made consider internal but I don't serve source maps to users that don't have a enough permission and I cant limit the internal sourcemap

My workaround for now is to just append the sourcemapping line myself after calling bun.build() in my build script -

	await Bun.build({
		entrypoints: ['src/index.ts'],
		outdir: 'dist',
		sourcemap: 'external'
	});
	await appendFile("dist/src/index.js", '\n//# sourceMappingURL=index.js.map');
