Types not resolving to `.js.flow` files

[](https://oss.issuehunt.io/r/gajus/flow-runtime/issues/27)

I'm using an npm package that transpiles its files then uses `flow-copy-source` to copy its flow annotated files to the package's `lib` folder. The result is there's an `index.js` file and an `index.js.flow` file. `index.js.flow` contains custom types exported by the application, while `index.js` has these stripped.

At compile time, the `flow-bin` binary resolves to `index.js.flow` instead of `index.js`, allowing the flow compiler to pick out the custom types. However, the flow-runtime babel plugin doesn't resolve `index.js.flow`first, causing flow-runtime to throw the error `Error: Could not reference the given type.`

If you could point me in the right direction in the code base I might be able to help submit a PR. If you have another suggestion on how I could fix this though I'd appreciate it!
