Package Exports

latest

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (latest) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

latest

Quickly determine the latest available version of a package in npm

Useful for command line tools that want to check for available upgrades

Example

Get the latest version number of autocast

var latest = require('latest');

latest('autocast', function(err, v) {
  console.log(v);
  // => "0.0.3"
});

Errors passed directly from npm

var latest = require('latest');

latest('i-hope-this-package-never-exists', function(err, v) {
  console.error(err.message);
  // => "404 Not Found: i-hope-this-package-never-exists"
});

Convenience Function

Check for upgrades in an app

var latest = require('latest');
var p = require('./package.json');

latest.checkupdate(p, function(ret, message) {
  console.log(message);
  // => "you are running the latest version 0.0.1"
  process.exit(ret);
  // => 0
});

checkupdate(package-json-obj, cb(ret, message))

A convenience method that will check for newer versions of a module in npm given a package.json object as the first argument.

The callback fires with a return code suitable for exiting with, and a message to print
