ehmicky/node-version-alias

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:

• latest,

stable, node, current: latest version

• lts or

lts/: latest LTS version

• lts/-1,

lts/-2, etc.: first/second/etc. latest LTS version

• lts/erbium,

erbium, etc.: specific LTS, using its name (case-insensitive)

• nvm custom aliases (including default)
• system: Node.js

version when nvm is deactivated

• iojs: always 4.0.0
• unstable: always 0.11.6

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')) // 19.3.0
console.log(await nodeVersionAlias('lts')) // 18.12.1
console.log(await nodeVersionAlias('lts/erbium')) // 12.22.12
console.log(await nodeVersionAlias('erbium')) // 12.22.12
console.log(await nodeVersionAlias('lts/-2')) // 14.21.2

// Normal version ranges
console.log(await nodeVersionAlias('10.0.0')) // 10.0.0
console.log(await nodeVersionAlias('10')) // 10.24.1

console.log(await nodeVersionAlias('=10')) // 19.3.0
