npm install bump-file

import bump from 'bump-file';

bump(file, [increment='patch']);

The second argument can also be an object:

bump(file, {
  increment,
  preId,        // Prerelease identifier (such as "alpha", "beta", "rc")
  get,          // Function to get version. Default: pkg => pkg.version
  set           // Function to set version. Default: (pkg, version) => pkg.version = version
});

You can install this globally (npm install -g bump-file), and use from CLI:

bump file [increment] [preId]

bump('package.json', 'minor'); // 1.0.0 → 1.1.0

bump('package.json', {         // 1.4.2 → 2.0.0-beta.0
  increment: 'premajor',
  preId: 'beta'
});

See the tests for more example.
