  • HonoJS: Small, simple, and ultrafast web framework for the Edges
    9 projects | news.ycombinator.com | 15 Apr 2024
    In cases where the client needs to stay separate, we have had a good experience with Orval[1] to generate a fully-typed @tanstack/query client from our OpenAPI spec.

  • Litestar – powerful, flexible, and highly performant Python ASGI framework
    8 projects | news.ycombinator.com | 26 Feb 2024
    - Vite/React/Tailwind for the frontend, with [Orval](https://orval.dev/) to generate FE definitions based on the API spec.

    For non-API/SPA use-cases, it also has good HTML support, with built-in Jinja and HTMX integrations. The docs are great (https://docs.litestar.dev/latest/ - not quite Django-tier but that's the gold standard), however the reference application is a tad too complex imo (https://github.com/litestar-org/litestar-fullstack).

    https://github.com/litestar-org/awesome-litestar has a list of useful extensions - highly recommend trying it out if you are starting a new Python web project.

    In order to generate the API client, there are a few options available, but we are going to use (Orval)[https://orval.dev]. Orval is a CLI tool that generates API clients based on an OpenAPI specification. It supports TypeScript, JavaScript, Axios, React, Vue, Angular and Svelte and it's highly customizable.
  • Getting the most out of vscode

    I would use "reveal": "never" if I don't care about the results of the command, for example, I generate swagger types using orval.dev on every folder open, but I want this to run in background as it's not that important, so I use "reveal": "never" for it.
  • Mock Service Worker(msw) releases 2.0
    8 projects | news.ycombinator.com | 23 Oct 2023
    we started using (and now contributing to) https://orval.dev/ this year which both generates the mocks using MSW as well as the client-side networking code (React Query in our case). It removes so much boilerplate its amazing.

  • Ask HN: Why isn't JSON-RPC more widely adopted?
    11 projects | news.ycombinator.com | 2 Jan 2023
    Personally, find gRPC-Web very attractive but the current state of TypeScript/JS code-gen is very confusing and lacking.

    I would love something like https://orval.dev for gRPC-web. Have I missed something or is it just early to expect it?

    I tried a few libraries but couldn't get them to work or would generate unappealing results. I believe I'm hitting this issue with my local experiments. https://github.com/grpc/grpc-web/issues/535

    If you have OpenAPI specs to work with you could also use Orval (https://orval.dev/) to generate a lot of code. We’re just starting to evaluate it at work but so far the team that’s trialing it is liking it.

    On the frontend we can use the OpenAPI docs to generate the TS types for our data structures. Not only types but fetch functions as well as react-query hook can be generated as well. And in this blog post you can see how to do that with a library called Orval.
