Typesafe APIs Made Simple 🪄

oRPC is a powerful combination of RPC and OpenAPI, makes it easy to build APIs that are end-to-end type-safe and adhere to OpenAPI standards, ensuring a smooth and enjoyable developer experience.

Highlights

• End-to-End Type Safety 🔒: Ensure complete type safety from inputs to outputs and errors, bridging server and client seamlessly.
• First-Class OpenAPI 📄: Adheres to the OpenAPI standard out of the box, ensuring seamless integration and comprehensive API documentation.
• Contract-First Development 📜: (Optional) Define your API contract upfront and implement it with confidence.
• Exceptional Developer Experience ✨: Enjoy a streamlined workflow with robust typing and clear, in-code documentation.
• Multi-Runtime Support 🌍: Run your code seamlessly on Cloudflare, Deno, Bun, Node.js, and more.

export function Setup() {
  const query = useQuery(orpc.planet.find.queryOptions({
    input: { id: 123 }, // Specify input if needed
    context: { cache: true }, // Provide client context if needed
  // additional options...
  }))

  const query = useInfiniteQuery(orpc.planet.list.infiniteOptions({
    input: (pageParam: number | undefined) => ({ limit: 10, offset: pageParam }),
    context: { cache: true }, // Provide client context if needed
    initialPageParam: undefined,
    getNextPageParam: lastPage => lastPage.nextPageParam,
  // additional options...
  }))

  const mutation = useMutation(orpc.planet.create.mutationOptions({
    context: { cache: true }, // Provide client context if needed
  // additional options...
  }))

  mutation.mutate({ name: 'Earth' })

  const queryClient = useQueryClient()

  // Invalidate all planet queries
  queryClient.invalidateQueries({
    queryKey: orpc.planet.key(),
  })

  // Invalidate only regular (non-infinite) planet queries
  queryClient.invalidateQueries({
    queryKey: orpc.planet.key({ type: 'query' })
  })

  // Invalidate the planet find query with id 123
  queryClient.invalidateQueries({
    queryKey: orpc.planet.find.key({ input: { id: 123 } })
  })
