ow-lite

Lightweight replacement for the ow validation library meant for browser usage.

Install

npm install --save ow-lite

Why

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

Library	Size	Minified	GZip
ow@0.5.0	119.61kb	65.95kb	17.58kb
ow-lite	6kb	2.2kb	903b

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.
