Walking a directory in Node.js

To recursively walk through the directory tree and get the path of each file in the tree, use the following code snippet:

const fs = require("fs");
const path = require("path");

function walkDirectory(directoryPath: string) {
return fs.readdirSync(directoryPath).flatMap((fileOrSubdirectory) => {
const fileOrSubdirectoryPath = path.join(directoryPath, fileOrSubdirectory);
if (fs.statSync(fileOrSubdirectoryPath).isDirectory()) {
return walkDirectory(fileOrSubdirectoryPath);
}
return [fileOrSubdirectoryPath];
})
};

const files = walkDirectory("/path/to/directory");
