• Include the dev-only file in the package 64ab6b8

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.

• Check for optional first before running validator (#125) 3de78ad

https://github.com/sindresorhus/ow/compare/v0.11.0...v0.11.1

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.

• Only infer label when predicate fails (#119) 67a06cb
• Add support for checking C style integer data types (#120) 410e567

• Import the fs module only in Node.js environments (#117) d24f2ef

Breaking

Ow now infers the label automatically on Node.js. For browser usage, the .label() method is removed in favor of an optional second ow() argument. 7eb02af

If you only use Ow in Node.js, you can change it like this:

- ow(foo, ow.string.minLength(5).label('foo'));
+ ow(foo, ow.string.minLength(5));

If you need browser support, you can change it like this;

- ow(foo, ow.string.minLength(5).label('foo'));
+ ow(foo, 'foo', ow.string.minLength(5));
