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

const normalizeNodeVersion = require('normalize-node-version')

await normalizeNodeVersion('8') // '8.16.0'
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://npm.taobao.org/mirrors/node',
  // Do not cache the list of available Node.js versions
  fetch: true,
})

Install

npm install normalize-node-version

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://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

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
