Hidden Gems of TypeScript compiler
summary
Shows the compiler’s actual internals—scanner, parser, binder, checker and emitter—and how the TypeScript Compiler API gets used to build real tools: semantic linting (TSLint/Codelyzer), code transforms (Angular CLI schematics, build optimizer), documentation (Compodoc, TypeDoc) and language-service plugins. Demonstrations include a working 3D dependency visualization derived from ASTs and a playful AST-to-music demo that maps decorators to notes, proving the transforms and analyses run end-to-end and produce useful, inspectable outputs.
