get-nodeDownload a specific version of Node.js
Download a specific version of Node.js.
The Node.js release is downloaded, uncompressed and untared to an executable file ready to run.
Fast:
- the download is cached
- the best compression algorithm available on your machine is used
- everything is streamed
Reliable:
- the binary is checked against official checksums
- can be safely run concurrently
- atomic writes
Features include:
- Linux/Mac/Windows support
- works with old Node.js versions
- progress bar
- using version ranges
- specifying a mirror website for nodejs.org
- helpful error messages
- can guess the current project's version using its
.nvmrc
orpackage.json
(engines.node
field)
Example
import getNode from 'get-node'
// Download a specific Node.js release
const { path, version } = await getNode('8')
console.log(path) // /home/user/.cache/nve/8.17.0/node
console.log(version) // 8.17.0
// Download Node.js latest release
const { path, version } = await getNode('latest')
console.log(path) // /home/user/.cache/nve/16.3.0/node
console.log(version) // 16.3.0
// Any version range can be used
await getNode('8.12.0')
await getNode('<7')
// Download latest LTS Node.js version
await getNode('lts')
// Download Node.js version from `~/.nvmrc` or the current process version
await getNode('global')
// Download current directory's Node.js version using its `.nvmrc` or `package.json` (`engines.node` field)
await getNode('local')
// Specify the output directory
const { path } = await getNode('8', {
output: '/home/user/.cache/node_releases/',
})
console.log(path) // /home/user/.cache/node_releases/13.0.1/node
// Use a mirror website
await getNode('8', { mirror: 'https://npm.taobao.org/mirrors/node' })
// Specify the CPU architecture
await getNode('8', { arch: 'x32' })
Install
npm install get-node
node >=12.20.0
must be globally installed. However any Node version can be downloaded.
This package is an ES module and must be loaded using an import
or import()
statement, not require()
.
To use this module as a CLI instead, please check get-node-cli
.
Usage
getNode(version, options?)
version
: string
options
: object?
Return value: Promise<object>
version
can be any version range such as 12
, 12.6.0
or <12
, or one of the following aliases:
-
latest
: Latest available Node version -
lts
: Latest LTS Node version -
global
: Global Node version- Using the home directory
.nvmrc
orpackage.json
(engines.node
field) - Some additional files used by other Node.js version managers are also searched for
- If nothing is found, defaults to the current process's Node version
- Using the home directory
-
local
: Current directory's Node version- Using the current directory or parent directories
.nvmrc
,package.json
(engines.node
field) (or additional files) - Defaults to the
global
version
- Using the current directory or parent directories
Options
output
Type: string
Default: global cache directory such as /home/user/.cache/nve/
.
Output directory for the node
executable.
It the directory already has a node
executable, no download is performed. This enables caching.
progress
Type: boolean
Default: false
Whether to show a progress bar.
mirror
Type: string
Default: https://nodejs.org/dist
Base URL to retrieve Node.js binaries. 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
arch
Type: string
Default: process.arch
Node.js binary's CPU architecture. This is useful for example when you're on x64 but would like to run Node.js x32.
All the values from process.arch
are allowed except mips
and mipsel
.
cwd
Type: string
Default: process.cwd()
When using the local
alias, start looking for a Node.js version file from this directory.
Return value
The returned Promise
resolves to an object with the following properties.
path
Type: string
Absolute path to the node
executable.
version
Type: string
Normalized Node.js version.
