OpenAPI React Query Codegen

Node.js library that generates React Query (also called TanStack Query) hooks based on an OpenAPI specification file.

Features

• Supports generation of custom react hooks that use React Query's useQuery and useMutation hooks
• Supports generation of query keys for query caching
• Supports the option to use pure TypeScript clients generated by OpenAPI Typescript Codegen

Example Usage

Command

$ openapi-rq -i ./petstore.yaml

Output directory structure

- openapi
  - queries
    - index.ts <- custom react hooks
  - requests <- output code generated by OpenAPI Typescript Codegen

In your app

// App.tsx
import {
  usePetServiceFindPetsByStatus,
} from "../openapi/queries";
function App() {
  const { data } = usePetServiceFindPetsByStatus({ status: ["available"] });

  return (
    <div className="App">
      <h1>Pet List</h1>
      <ul>
        {data?.map((pet) => (
          <li key={pet.id}>{pet.name}</li>
        ))}
      </ul>
    </div>
  );
}

export default App;

You can also use pure TS clients.

import { useQuery } from "@tanstack/react-query";
import { PetService } from '../openapi/requests/services/PetService';
import {
  usePetServiceFindPetsByStatusKey,
} from "../openapi/queries";

function App() {
  // You can still use the auto-generated query key
  const { data } = useQuery([usePetServiceFindPetsByStatusKey], () => {
    // Do something here
  
    return PetService.findPetsByStatus(['available']);
  });

  return (
    <div className="App">
      {/* .... */}
    </div>
  );
}

export default App;
