Find vfiles by searching the file system upwards.

Install

This package is ESM only: Node 12+ is needed to use it and it must be imported instead of required.

npm:

npm install vfile-find-up

Use

import {findUp} from 'vfile-find-up'

findUp('package.json', console.log)

Yields:

null [ VFile {
  data: {},
  messages: [],
  history: [ '/Users/tilde/projects/oss/vfile-find-up/package.json' ],
  cwd: '/Users/tilde/projects/oss/vfile-find-up' } ]

API

This package exports the following identifiers: findUp, findUpOne, INCLUDE, BREAK. There is no default export.

findUp(tests[, path][, callback])

Search for tests upwards. Calls callback with either an error or an array of files passing tests. Note: Virtual Files are not read (their contents is not populated).

Sigantures
Parameters
tests

Things to search for (string, Function, or Array.<tests>).

If a string is passed in, the basename or extname of files must match it for them to be included.

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

Otherwise, they must be function.

path

Place to searching from (string, default: process.cwd()).

callback

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

findUpOne(tests[, path][, callback])

Like findUp, but either calls callback with the first found file, or null or without callback resolves to a file or null.

function test(file)

Check whether a virtual file should be included. Called with a vfile.

Returns

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