trpc-openapi VS wundergraph

tRPC does not natively export OpenAPI documents, but the trpc-openapi package adds this functionality. We'll start this tutorial by adding trpc-openapi to a project, and then we'll add a script to generate an OpenAPI schema and save it as a file.

While trpc-openapi originally was used to expose REST endpoints of the tRPC router, we will use it to generate an OpenAPI specification for our API.

Sure it can, you can use https://github.com/prosepilot/trpc-openapi

You either have to go with react native or use https://github.com/jlalmes/trpc-openapi to generate rest endpoint using trpc. lol. Not sure how good the trpc-openapi package is though. Read somewhere it was missing stuff

As for exposing the API externally, neither (can) limit this but SvelteKit's API is generally considered to be an internal implementation detail that you don't use directly since it might change between versions. If you want to expose an API you should choose tRPC, probably alongside the OpenAPI plugin or something similar.

In essence, features of the language made for static type checking at compilation are possibly being left favour of tools that act like a superset of the language that provide the static build type checking and offer runtime type checking too. An example I recently saw was the trpc-openapi package which uses Zod for creating the types of the schema for the http request and responses, it takes a zod schema as that is what it can use when compiled to JavaScript to generate the types for the openapi file at runtime, there's scarcely a type or interface in sight when using it but you have full type safety.

Take a look at https://github.com/jlalmes/trpc-openapi which will give you a rest endpoint based on your trpc router. Ymmv in reality but basically this should give you some confidence that your trpc router can be called from another client (not just next).

Ok thanks, I did find a good example here https://github.com/jlalmes/trpc-openapi/blob/master/examples/with-nextjs/src/server/router.ts

There is an OpenAPI Extension for tRPC that can be used to create a more REST-like API from your procedures, and that in turn can be used for auto-generating documentation. But if my app needed to offer third-party API access, I would likely reach for GraphQL again.

tRPC is nice because you have type safety the whole way down. Someone has made a tRPC OpenaAPI for exposing tRPC procedures externally in the OpenAPI format https://github.com/jlalmes/trpc-openapi

I never really got graphql until I stumbled upon Wundergraph. (https://github.com/wundergraph/wundergraph). I have no affiliation with them except that I have been building an app with it. I'm honestly puzzled how it's not more popular. Maybe people are solving these problems in other ways? But I tried out a bunch of stuff: Vapor, Supabase, Hasura, etc. None of it simplifies building complex systems the way WG does.

I think their takes on graphql make sense: https://wundergraph.com/blog/graphql_is_not_meant_to_be_expo...

To demonstrate field usage metrics in Federation, I’ll be using WunderGraph Cosmo — a fully open source, fully self-hostable platform for Federation V1/V2 that is a drop in replacement for Apollo GraphOS.

The inverse is also true. As a technical founder, and maybe even an introvert like me, you should definitely look for a non-technical co-founder who can help you with networking, etc... I found my dream co-founder through YC Co-founder match and what can I say, it's going great. We're focusing on enterprise GraphQL/API solutions (https://wundergraph.com) and I benefit from the networking and communication abilities of Stefan, while I answer all technical questions. Tldr, I highly recommend to team up with people who complement your skills.

GraphQL Gateway is primarily responsible for serving GraphQL queries to consumers. It takes a query from a client, breaks it into smaller sub-queries, and executes that plan by proxying calls to the appropriate downstream subgraphs. When we started our journey, there was only Apollo Federation in the arena, and we used it. Still, now you can look at other options (e.g. Mercurius, Conductor, Hot Chocolate, Wundergraph, Hasura Remote Schemas), compare benchmarks and decide what's important and preferable for your needs. The Gateway provides a unified API for consumers while giving backend engineers flexibility and service isolation.

I'm a big fan of tRPC. It's amazing how it pushed TypeScript only stacks to the limit in terms of DX. Additionally, it made the GraphQL community aware of the limitations and tradeoffs of the Query language. At the same time, I think tRPC went through a really fast hype cycle and it doesn't look like we're seeing a massive move away from REST and GraphQL to RPC. That said, we see a lot of interest in RPC these days as we've adopted some ideas from tRPC and the old NextJS. In our BFF framework (https://wundergraph.com/) we've combined file based routing with RPC. In addition to tRPC, we're automatically generating a JSON Schema for each operation and an OpenAPI spec for the whole set of operations. People quite like this approach because you can easily share a set of RPC endpoints as an OpenAPI spec or postman collection. In addition, there are no discussions around HTTP verbs and such, there's only really queries, mutations and subscriptions. I'm curious what other people's experiences are with GraphQL, REST and RPC style APIs? What are you using these days and how many people/teams are involved/using your apis?
