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:
Example
const getNode = require('get-node')
const { path, version } = await getNode('8')
console.log(path)
console.log(version)
const { path, version } = await getNode('*')
console.log(path)
console.log(version)
await getNode('8.12.0')
await getNode('<7')
await getNode('latest')
await getNode('current')
const { path } = await getNode('8', {
output: '/home/user/.cache/node_releases/',
})
console.log(path)
await getNode('8', { mirror: 'https://npm.taobao.org/mirrors/node' })
await getNode('8', { arch: 'x32' })
Install
npm install get-node
