Package com.google.javascript.jscomp

Class InjectTranspilationRuntimeLibraries

java.lang.Object

com.google.javascript.jscomp.InjectTranspilationRuntimeLibraries

All Implemented Interfaces:

CompilerPass

public final class InjectTranspilationRuntimeLibraries
extends Object
implements CompilerPass

Injects JS library code that may be needed by the transpiled form of the input source code.

The intention here is to add anything that could be needed and rely on RemoveUnusedCode to remove the parts that don't end up getting used. This pass should run before type checking so the type checking code can add type information to the injected JavaScript for checking and optimization purposes.

TODO(b/120486392): consider merging this pass with InjectRuntimeLibraries and RewritePolyfills.
