Typescript meta programming from 0 to 100
summary
A demo shows concrete claims and working code: TypeScript compiler metadata plus reflect-metadata and simple decorators let an injectable decorator record constructor dependencies so a small recursive injector resolves instances at runtime; a 4.5 kilobyte bundle example emphasizes low overhead. The build includes a provider override (a stub replacement) and an Express-style controller router generated from method decorators; the live coding compiles and runs, proving the techniques work.
