# fbjs-scripts This 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) var invariant = require('fbjs/lib/invariant'); var devExpression = require('fbjs/scripts/babel/dev-expression'); // after (fbjs, fbjs-scripts@0.2.0) var invariant = require('fbjs/lib/invariant'); var devExpression = 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.
