Codecov Build Node Twitter Medium

Resolve Node.js version aliases like latest, lts or erbium.

Those aliases are used by Node.js version managers like nvm, nvs, n, nave, nodeenv or nodist.

This resolves them to a "major.minor.patch" version string. The following aliases are supported:

Normal version ranges (like 12.1.0, 12 or >=10) are valid inputs too.

Examples

import nodeVersionAlias from 'node-version-alias'

// Note: the following examples might be out-of-sync with the actual versions
console.log(await nodeVersionAlias('latest')) // 13.13.0
console.log(await nodeVersionAlias('lts')) // 12.16.2
console.log(await nodeVersionAlias('lts/erbium')) // 12.16.2
console.log(await nodeVersionAlias('erbium')) // 12.16.2
console.log(await nodeVersionAlias('lts/-2')) // 10.20.1

// Normal version ranges
console.log(await nodeVersionAlias('10.0.0')) // 10.0.0
console.log(await nodeVersionAlias('10')) // 10.20.1
console.log(await nodeVersionAlias('^10')) // 10.20.1
console.log(await nodeVersionAlias('>=10')) // 13.13.0

// Allowed options
await nodeVersionAlias('latest', {
  // Use a mirror for Node.js binaries
  mirror: 'https://npm.taobao.org/mirrors/node',
  // Do not cache the list of available Node.js versions
  fetch: true,
})

Install

npm install node-version-alias

This package is an ES module and must be loaded using an import or import() statement, not require().

Usage

nodeVersionAlias(alias, options?)

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

The return value resolves to a "major.minor.patch" version 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://npm.taobao.org/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
