vfile-find-down

Find vfiles by searching the file system downwards.

Install

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

npm install vfile-find-down

Use

var findDown = require('vfile-find-down')

findDown('.md', console.log)

Yields:

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

API

This package exports the following identifiers: findDown, findDownOne, INCLUDE, SKIP, 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. Note: Virtual Files are not read (their contents is not populated).

Signatures

(tests: Tests, paths?: string|Array.<string>, callback: Callback): void
(tests: Tests, paths?: string|Array.<string>): Promise.<Array.<VFile>>

Parameters

`tests`

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 function.

`paths`

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

`callback`

Function called with all matching files (function cb(err[, 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 test(file, stats)`

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

Returns

true or INCLUDE — Include the file in the results
SKIP — Do not search inside this directory
BREAK — Stop searching for files
anything else is ignored: files are neither included nor skipped

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