vfile utility to find files by searching the file system downwards.


What is this?

This utility lets you find one or many files downwards.

When should I use this?

You can use this utility if you want to find files in, say, a folder. One example is all markdown files. If you instead want to find files upwards, such as config files, you can use vfile-find-up.


This package is ESM only. In Node.js (version 12.20+, 14.14+, 16.0+, or 18.0+), install with npm:

npm install vfile-find-down


import {findDown} from 'vfile-find-down'

console.log(await findDown('.md'))


[ VFile {
  data: {},
  messages: [],
  history: [ '/Users/tilde/projects/oss/vfile-find-down/readme.md' ],
  cwd: '/Users/tilde/projects/oss/vfile-find-down' } ]


This package exports the identifiers findDown, findDownOne, INCLUDE, SKIP, and BREAK. There is no default export.

findDown(tests[, paths][, callback])

Search for tests downwards. Calls callback with either an error or an array of files passing tests, or returns them as a promise if no callback is passed.

👉 Note: files are not read (their value is not populated).


Things to search for (string|Function|Array<Tests>).

If an array is passed in, any test must match a given file for it to be included.

If a string is passed in, the basename or extname of files must match it for them to be included (and hidden directories and node_modules will not be searched).

Otherwise, they must be Assert.


Place or places to search from (Array<string> or string, default: process.cwd()).


Function called with all matching files (function cb(error[, files])).

findDownOne(tests[, paths][, callback])

Like findDown, but either calls callback with the first found file or null, or returns a promise that resolved to a file or null.

function assert(file, stats)

Check whether a file should be included. Called with a vfile and a stats object.


The different flags can be combined by using the pipe operator: INCLUDE | SKIP.


This package is fully typed with TypeScript. It exports the additional types Assert and Test.
