vfile utility to find files by searching the file system upwards.
This utility lets you find one or many files upwards.
You can use this utility if you want to find, say, a config file.
If you instead want to find files downwards, such as all markdown files in a
folder, you can use vfile-find-down
.
This package is ESM only. In Node.js (version 16+), install with npm:
npm install vfile-find-up
import {findUp} from 'vfile-find-up'
console.log(await findUp('package.json'))
Yields:
VFile {
cwd: '/Users/tilde/Projects/oss/vfile-find-up',
data: {},
history: [ '/Users/tilde/Projects/oss/vfile-find-up/package.json' ],
messages: []
}
This package exports the identifiers findUp
and
findUpAll
.
There is no default export.
Find the first file or folder upwards.

value
is not populated). useto-vfile
for that.

Nothing when callback
is given (undefined
), otherwise a promise that
resolves to a file (VFile | undefined
).

Projects maintained by the unified collective are compatible with maintained versions of Node.js.
When we cut a new major release, we drop support for unmaintained versions of
Node.
This means we try to keep the current release line, vfile-find-up@^7
,
compatible with Node.js 16.
