@unindented Are you a maintainer of normalizr? Would you be interested in keeping the type definitions inside the repo itself instead? Doing that would provide immediate value for TypeScript users instead of making them use Typings.

[unindented]

@blakeembrey You are right, that's the better option. Adding a typings field to the package.json that points to the .d.ts file would be enough, right?

[blakeembrey]

Yes, that's all you need to do and TypeScript users will appreciate it 😄

You're welcome to ping me too, if you need a definition review.
