О чём код?
import * as fs from "fs"; if (process.argv.length < 3) { process.exit(1); } const directoryName = process.argv[2]; // main reason why we need separate process to check if it is safe to watch some path // is to guard against crashes that cannot be intercepted with protected blocks and // code in tsserver already can handle normal cases, like non-existing folders. // This means that here we treat any result (success or exception) from fs.watch as success since it does not tear down the process. // The only case that should be considered as failure - when watchGuard process crashes. try { const watcher = fs.watch(directoryName, { recursive: true }, () => ({})); watcher.close(); } catch { /*ignore*/ } process.exit(0);
