Normalize and validate Node.js versions.

Can load the current project's version using its .nvmrc.

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('8.5.2') // Error: Invalid Node version
await normalizeNodeVersion('<7') // '6.17.1'
await normalizeNodeVersion('*') // Latest Node version, e.g. '12.8.0'
await normalizeNodeVersion('_') // Node version used by current process
await normalizeNodeVersion('.') // Node version from a '.nvmrc', '.node-version' or '.naverc' file in the current directory or any parent directory
await normalizeNodeVersion('not_a_version') // Error: Invalid Node version

// All available options
await normalizeNodeVersion('8', {
  cache: false,
  mirror: 'https://npm.taobao.org/mirrors/node',
})

npm install normalize-node-version

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

versionRange can be one of the following aliases:

• _ : Current process's Node.js version
• . : Node version from a .nvmrc, .node-version or .naverc file in the current directory or any parent directory. Defaults to the current process's Node.js version

Type: boolean
Default: true

Cache the HTTP request to retrieve the list of available Node.js versions. The cache is invalidated after one hour.

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

Base URL. 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.

Type: string
Default: process.cwd()

When using the . alias, start looking for a Node.js version file from this directory.

• nve: Run a specific Node.js version (CLI)
• nvexeca: Run a specific Node.js version (programmatic)
• get-node: Download Node.js
• all-node-versions: List all available Node.js versions
• fetch-node-website: Fetch releases on nodejs.org
