Reactjs client for Swagger / OpenAPI API specification

问题

Background

Using Swagger Editor, I created a spec for my API. I see that Swagger also provide a "Generate a client" option in their Swagger Editor (probably using Swagger Codegen).

Objective

I want to generate a client and use it in my React app (created with create-react-app), and preferably enjoy some static typing capabilities (currently using flow).

Currently

None of the options in Swagger Editor there seem to work:

javascript - provides a vanilla node module that you need to npm install it as a dependency to your project. Now, not only this doesn't have any classes / types, but also fails with: Uncaught Error: Cannot find module "ApiClient" at webpackMissingModule (index.js:17) at exports.ApiClient (index.js:17) at Object.<anonymous> (index.js:22) at __webpack_require__ (bootstrap 75f547b…:555) at fn (bootstrap 75f547b…:86) at new Index (index.js:87) at ReactCompositeComponent.js:295 at measureLifeCyclePerf (ReactCompositeComponent.js:75) at ReactCompositeComponentWrapper._constructComponentWithoutOwner (ReactCompositeComponent.js:294) at ReactCompositeComponentWrapper._constructComponent (ReactCompositeComponent.js:280)
typescript-* options are not compatible with js, and I don't necessarilty know how / want to add TypeScript to my project.
*-angular options are of course irrelevant.

Approaches

Generate .ts file and covert it to flow. How??
Manually adding the generated .js files to my project. Currently doesn't work as the generated code comes with its own dependencies.
Add TypeScript to my project (should I replace flow then?). How??

Thanks
