get-latest-version

Find the latest version of an npm module matching a given semver range

Installing

npm install --save get-latest-version

Basic usage

const getLatestVersion = require('get-latest-version')

getLatestVersion('some-module')
  .then((version) => console.log(version)) // 1.0.0, or whichever is 'latest'
  .catch((err) => console.error(err))

getLatestVersion('some-other-module', {range: '^1.0.0'})
  .then((version) => console.log(version)) // highest version matching ^1.0.0 range
  .catch((err) => console.error(err))

// Returns both the highest in the given range and the actual `latest` tag
// Note that this differens in that the return value is an object
getLatestVersion('@sanity/base', {range: '^1.0.0', includeLatest: true})
  .then((versions) => console.log(versions)) // {inRange: '1.150.8', latest '2.23.0'}
  .catch((err) => console.error(err))

Disabling authenticated requests

By default, this module will read the authorization token for whichever registry the module belongs to, based on local npm configuration. To disable this and always send unauthenticated requests to the registry, provide auth: false to the options:

getLatestVersion('some-module', {auth: false})
  .then((version) => console.log(version))
  .catch((err) => console.error(err))

Using custom registry

By default, module utilizes registry-url to resolve registry URL from NPM configuration files. However, if you need to set up the registry programmatically, you can make use of the registryUrl option:

getLatestVersion('some-module', {registryUrl: 'https://some-custom-registry.com'})
  .then((version) => console.log(version))
  .catch((err) => console.error(err))
