For most of us, the Angular compiler is just a part of the build - it's that thing that happens before the "real" work of compilation: 92% chunk asset optimization. But how does it actually work? What does the Angular compiler _do_ when it's taking our Angular code and generating Javascript? Alex Rickabaugh has been preparing ngc for Ivy, and will unwrap some of the _deep_ mysteries of the compiler. How does @NgModule really work? What are metadata.json files? Come learn these and many more secrets of the Angular compiler.
