Class ProcessCommonJSModules

java.lang.Object

com.google.javascript.jscomp.ProcessCommonJSModules

All Implemented Interfaces:

CompilerPass

public class ProcessCommonJSModules
extends java.lang.Object
implements CompilerPass

Rewrites a CommonJS module http://wiki.commonjs.org/wiki/Modules/1.1.1 into a form that can be safely concatenated. Does not add a function around the module body but instead adds suffixes to global variables to avoid conflicts. Calls to require are changed to reference the required module directly. goog.provide and goog.require are emitted for closure compiler automatic ordering.
