[![npm version](https://img.shields.io/npm/v/get-latest-version.svg?style=flat-square)](https://www.npmjs.com/package/get-latest-version)[![Build status](https://img.shields.io/github/actions/workflow/status/rexxars/get-latest-version/test.yml?branch=main&style=flat-square)](https://github.com/rexxars/get-latest-version/actions/workflows/test.yml)

## Requirements

- Node.js 20 or higher
- This package is now ESM-only and uses named exports. If you need CommonJS support, use version 5.x.

## Installing

```
npm install --save get-latest-version
```

## Basic usage

```js
import {getLatestVersion} from 'get-latest-version'

// Get the latest version
try {
  const version = await getLatestVersion('some-module')
  console.log(version) // 1.0.0, or whichever is 'latest'
} catch (err) {
  console.error(err)
}

// Get highest version matching a semver range
try {
  const version = await getLatestVersion('some-other-module', {range: '^1.0.0'})
  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 differs in that the return value is an object
try {
  const versions = await getLatestVersion('@sanity/base', {range: '^1.0.0', includeLatest: true})
  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:

```js
import {getLatestVersion} from 'get-latest-version'

try {
  const version = await getLatestVersion('some-module', {auth: false})
  console.log(version)
} catch (err) {
  console.error(err)
}
```

## Using custom registry

By default, module utilizes [registry-url](https://www.npmjs.com/package/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:

```js
import {getLatestVersion} from 'get-latest-version'

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

## Developing

```bash
git clone git@github.com:rexxars/get-latest-version.git

npm install
npm test
```
