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.


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: '',
  // Do not cache the list of available Node.js versions
  fetch: true,
