Very cool snippet showing the use of a JS generator to walk a directory recursively. Yields the path of files found.
Raw
recursive-file-lister-generator.js
/**
* @param {string} rootPath
* @returns {Generator<string>}
*/
function* walk(rootPath) {
for (const entry of fs.readdirSync(rootPath, { withFileTypes: true })) {
const filePath = path.join(rootPath, entry.name);
if (entry.isDirectory()) yield* walk(filePath);
else yield filePath;
}
}
