Search for modules with type definitions #137
Description
It'd be really cool to be able to search modules that have TypeScript definitions. These modules can be identified by types or typings as a string pointing to a .d.ts file at the root of package.json. I'd be happy to attempt this if there's a pointer on where to start and whether it sounds like an acceptable feature. It could be implemented as a new option, or something is is:types. There's also the @types namespace on NPM which are third-party definitions, those could be included with is:@types (being a inferior alternative to native types).
