# fbjs-scriptsThis is a collection of tools and scripts intended to be used in conjunction with `fbjs`. Previously these were shipped as a part of `fbjs`.```js// before (fbjs@0.1.0)varinvariant=require('fbjs/lib/invariant');vardevExpression=require('fbjs/scripts/babel/dev-expression');// after (fbjs, fbjs-scripts@0.2.0)varinvariant=require('fbjs/lib/invariant');vardevExpression=require('fbjs-scripts/babel/dev-expression');```## Why?This ensures that production code consuming `fbjs` library code does not need to install script dependencies, unless you explicitly use them via the `fbjs-scripts` package.
