ow-lite supports the most practical ow usage and is 30x smaller, which is really important for browser usage.

ow-lite has the following drawbacks:

• less verbose error messages
• less support for uncommon types and predicate methods

Usage

You may use ow-lite as a mostly drop-in replacement for ow. It supports the following types:

• number
• string
• object

Webpack's resolve.alias is a solid option for replacing ow with ow-lite at build time. See also ow-shim if you want to replace ow usage with noops in production.
