openapi-react-query

openapi-react-query is a type-safe tiny wrapper (1 kb) around @tanstack/react-query to work with OpenAPI schema.

It works by using openapi-fetch and openapi-typescript so you get all the following features:

• ✅ No typos in URLs or params.
• ✅ All parameters, request bodies, and responses are type-checked and 100% match your schema
• ✅ No manual typing of your API
• ✅ Eliminates any types that hide bugs
• ✅ Eliminates as type overrides that can also hide bugs

Setup

Install this library along with openapi-fetch and openapi-typescript:

npm i openapi-react-query openapi-fetch
npm i -D openapi-typescript typescript

Next, generate TypeScript types from your OpenAPI schema using openapi-typescript:

npx openapi-typescript ./path/to/api/v1.yaml -o ./src/lib/api/v1.d.ts

Usage

Once your types have been generated from your schema, you can create a fetch client, a react-query client and start querying your API.

import createFetchClient from "openapi-fetch";
import createClient from "openapi-react-query";
import type { paths } from "./my-openapi-3-schema"; // generated by openapi-typescript

const fetchClient = createFetchClient<paths>({
  baseUrl: "https://myapi.dev/v1/",
});
const $api = createClient(fetchClient);

const MyComponent = () => {
  const { data, error, isPending } = $api.useQuery(
    "get",
    "/blogposts/{post_id}",
    {
      params: {
        path: { post_id: 5 },
      },
    }
  );

  if (isPending || !data) return "Loading...";

  if (error) return `An error occurred: ${error.message}`;

  return <div>{data.title}</div>;
};

You can find more information about createFetchClient in the openapi-fetch documentation.
