**browserify-global-shim** is a browserify transform that replaces module `require()` calls with references to global variables, making it ideal for developers who want to exclude large, already-included libraries like jQuery or lodash from their browserify builds. It's particularly useful for those working with existing web apps that already include these libraries globally and want to avoid bundling them again. This tool is for developers using browserify who need a lightweight way to handle dependencies on global libraries without duplicating them in their build output.
