Looks like ignored can also be of type string when only one entry is needed, or a regex. I don't find proper docs for it, maybe it is better to first send this change to chokidar so it is properly discussed there, and then we can port it here?

Yes, you are right. But it seems to introduce another problem. we make the assumption that it is just an array. It will be throw error '/foo/ is not iterable' if the user just writes ignore: /foo/.

vite/packages/vite/src/node/server/index.ts

Lines 320 to 322 in eef51cb

	const { ignored = [], ...watchOptions } = serverConfig.watch || {}
	const watcher = chokidar.watch(path.resolve(root), {
	ignored: ['**/node_modules/**', '**/.git/**', ...ignored],

I will close this and open another PR to fix it. Thanks for all the guidance.

wow. Not expected PR(paulmillr/chokidar#1140) being merged immediately.

Warning: types/chokidar.d.ts:124:3 - (ae-forgotten-export) The symbol "AnymatchMatcher" needs to be exported by the entry point index.d.ts

API Extractor completed with warnings

The warning is killing me. I couldn't solve it by reading the warning and doc. Simply re-export it in ' types/chokidar.d.ts' doesn't solve the problem and I fail to find location of entry point index.d.ts.

exporting warning types from packages/vite/src/node/index.ts solve it.
