I'm building an app in TypeScript for Angular2.alpha27.
Was trying to get rid of my own forged angular2.d.ts definition by using the angular2.api.ts from the node_modules/angular2/ts. Everything compiles, but I get an error in the browser "Module angular2/src/core/compiler/interfaces not declared as a dependency".
On the other hand when I try the definitions from es6 or just main directory of angular2 from node_modules I get plenty of compilation errors.
Main motivation for this is angular2/forms, which initially is not supported by definitions obtained from DefinitlyTyped or angular2-seed project.
