Normalize and validate Node.js versions.

Takes any version range as inputs such as 8, 8.5.0 or >=8 and returns a "major.minor.patch" string. Throws if the Node.js version does not exist.

Example

import normalizeNodeVersion from 'normalize-node-version'

await normalizeNodeVersion('8') // '8.17.0'
await normalizeNodeVersion('8.5.0') // '8.5.0'
await normalizeNodeVersion('v8.5.0') // '8.5.0'
await normalizeNodeVersion('<7') // '6.17.1'
await normalizeNodeVersion('8.5.2') // Error: Invalid Node version
await normalizeNodeVersion('not_a_version') // Error: Invalid Node version

// All available options
await normalizeNodeVersion('8', {
  // Use a mirror for Node.js binaries
  mirror: 'https://npmmirror.com/mirrors/node',
  // Do not cache the list of available Node.js versions
  fetch: true,
  // Cancels when the signal is aborted
  signal: new AbortController().signal,
})

Install

npm install normalize-node-version

This package works in Node.js >=18.18.0.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.

Usage

normalizeNodeVersion(versionRange, options?)

versionRange: string
options: object?
Returns: Promise<string>

options

mirror

Type: string
Default: https://nodejs.org/dist

Base URL to fetch the list of available Node.js versions. Can be customized (for example https://npmmirror.com/mirrors/node).

The following environment variables can also be used: NODE_MIRROR, NVM_NODEJS_ORG_MIRROR, N_NODE_MIRROR or NODIST_NODE_MIRROR.

fetch

Type: boolean
Default: undefined

The list of available Node.js versions is cached for one hour by default. If the fetch option is:

• true: the cache will not be used
• false: the cache will be used even if it's older than one hour

signal

Type: AbortSignal

Cancels when the signal is aborted.
