What is this?

This package is a utility to add different data-driven ways to rename files.

When should I use this?

This package is mostly useful when creating higher level tools that include support for renaming files to end users.

Install

This package is ESM only. In Node.js (version 16+), install with npm:

npm install vfile-rename

In Deno with esm.sh:

import {rename} from 'https://esm.sh/vfile-rename@3'

In browsers with esm.sh:

<script type="module">
  import {rename} from 'https://esm.sh/vfile-rename@3?bundle'
</script>

Use

import {VFile} from 'vfile'
import {rename} from 'vfile-rename'

const file = new VFile({path: 'readme.md'})
file.path // => readme.md

// Set extname:
rename(file, '.html')
file.path // => readme.html

// Set basename:
rename(file, 'main.md')
file.path // => main.md

// Set path properties:
rename(file, {stem: 'index'})
file.path // => index.md

// Change path properties:
rename(file, {stem: {suffix: '.bak'}})
file.path // => index.bak.md

// All together:
rename(file, ['readme.md', '.htm', {stem: 'index', extname: {suffix: 'l'}}])
file.path // => index.html

API

This package exports the identifiers convert and rename. There is no default export.

convert(renames)

Create a function (the move) from renames, that when given a file changes its path properties.

Parameters

• renames (Renames, optional) — rename instructions

Returns

A move (Move).

rename(file, renames)

Rename a file.

When given something, returns a vfile from that, and changes its path properties.

Parameters

• file (VFile) — file to rename
• renames (Renames, optional) — rename instructions

Returns

Nothing (undefined).

Move

Move (TypeScript type).

Parameters

• file (VFile) — file to change

Returns

Nothing (undefined).

Renames

Rename instructions (TypeScript type).

• if the bound rename is a normal string starting with a dot (.), sets file.extname
• otherwise, if the bound rename is a normal string, sets file.basename
• otherwise, if the bound test is an array, all renames in it are performed
• otherwise, if the bound rename is an object, renames according to the Spec

Type

type Renames = Array<Move | Spec | string> | Move | Spec | string

Spec

An object describing path properties to values (TypeScript type).

For each property in spec, if its value is string, the value of the path property on the given file is set. If the value is object, it can have a prefix or suffix key, the value of the path property on the given file is prefixed and/or suffixed.

Fields

• basename (SpecAffix or string, optional) — change basename ('index.min.js').
• dirname (SpecAffix or string, optional) — change dirname ('~').
• extname (SpecAffix or string, optional) — change extname ('.js').
• path (SpecAffix, URL, or string, optional) — change file path ('~/index.min.js').
• stem (SpecAffix or string, optional) — change stem ('index.min').

SpecAffix

Define prepending and/or appending (TypeScript type).

Fields

• prefix (string, optional) — substring to prepend before the field
• suffix (string, optional) — substring to append after the field.

Types

This package is fully typed with TypeScript. It exports the types Move, Renames, Spec, and SpecAffix.

Compatibility

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-rename@^3, compatible with Node.js 16.

Security

Use of vfile-rename is safe.
