What is @types/which?
The @types/which package provides TypeScript type definitions for the 'which' npm package. 'which' is a utility that locates and returns the path to an executable in the system path, similar to the Unix 'which' command. The @types/which package does not contain functionality itself but provides type definitions to help TypeScript developers use the 'which' package with type safety.
Type definitions for finding an executable in the path
This code sample demonstrates how to use the 'which' package with TypeScript type definitions provided by @types/which. It attempts to locate the 'node' executable in the system path and prints its location or an error if not found.
import which from 'which';
which('node', (err, resolvedPath) => {
if (err) {
console.error('Node executable not found');
return;
}
console.log('Node executable located at:', resolvedPath);
});
