v0.14.0

Breaking

• Require Node.js 8 25be9db

Enhancements

• Export shim if running on browser in production (#129) acc5c9b
  Note: If you intend on using ow for development purposes only, use require('ow/dev-only') instead of the usual import 'ow', and run the bundler with NODE_ENV set to production (e.g. $ NODE_ENV="production" parcel build index.js). This will make ow automatically export a shim when running in production, which should result in a significantly lower bundle size.

v0.11.0...v0.11.1

v0.11.0

Add support for optional predicates (#124) 44272ab 🎉

This means you can now validate the input if it exists and ignore it if it doesn't.

// This passes
ow(2, ow.optional.number);

// This passes too
ow(undefined, ow.optional.number);

// This fails
ow(true, ow.optional.number);

We chose to only allow undefined and not null as that's how default parameters work too.
