rtk-query VS orval

The Redux library is quite a common choice thanks to its broad ecosystem. Luckily, there is now a very useful Redux Toolkit that mitigates the amount of boilerplate you have to usually write. RTK Query is a very new Redux solution for data fetching and caching, hopefully making our lives even easier. Though the web seems to slowly be moving away from Redux to React Query, SWR or other solutions, mobile is a different story; Redux is holding on to its popularity, as it integrates well with libraries that persist and rehydrate the global state for users when they relaunch the app.

rtk query is built-in to the redux toolkit starting from v 1.6

For api data. Check out rtk query https://rtk-query-docs.netlify.app/ It is supposed to better for api data with redux. I have not yet tried it.

I haven't looked at Kea in a while, but I'll toss out some comparisons based on my knowledge of RTK and what I remember about Kea + looking at its docs.

Kea's main selling point is that it lets you define self-contained chunks of Redux logic. Initially, this is similar to RTK's `createSlice`, in that you're writing a set of "case reducers" + action creators. However, it also build in Redux-Saga as a general-purpose side effects approach, and lets you write "listeners" that respond to dispatched actions.

Where it particularly differs from RTK is in the amount of abstraction included. RTK tries to stay "visibly Redux" [0], and the abstractions are fairly thin - the focus is on simplifying the typical Redux code patterns, without hiding the fact that you're using Redux. Kea is much more heavily abstracted. It does use a number of Redux terms ("actions", "reducers", etc), but the code that you write looks noticeably different than a "typical" Redux app. Also, RTK focuses on thunks as the default async approach, rather than sagas [1]

I believe Kea also has some mechanisms for combining together those "logic" chunks in various ways, including doing so dynamically at runtime, and it appears to have some "lifecycle"-type callbacks for handling when those chunks get mounted and unmounted.

RTK Query [2] [3], on the other hand, is a purpose-built data-fetching abstraction, most similar to React Query and Apollo. Its only purpose is to fetch data from whatever URL endpoints you've defined, handle the loading state, update the cache with the results, and re-render whatever components care about that data.

I haven't actually used Kea myself, but it does appear to have some meaningful thought and development put into it. I would still recommend RTK as the default approach for anyone wanting to use Redux (and of course I'm biased there), but Kea has some interesting approaches.

tl;dr Apollo, URQL, SWR, react-query, nor even RTK Query are meant to be wholesale replacements for Redux which is meant for global state.

You may want to look into our upcoming "RTK Query" API, which is specifically designed to abstract the process of fetching and caching data for Redux. We've got one more alpha release coming up that we're finalizing now, and then we'll be merging the APIs back into Redux Toolkit itself and releasing it.

Redux provides state management that has been widely used across many different web ecosystems for a long time. NgRx provides a more opinionated, batteries-included framework for managing state and side effects in the Angular ecosystem based on the Redux pattern. Redux Toolkit provides users of Redux the same batteries-included approach with conveniences for setting up state management and side effects. The Redux Toolkit (RTK) team has recently released RTK Query, described as "an advanced data fetching and caching tool, designed to simplify common cases for loading data in a web application", built on top of Redux Toolkit and Redux internally. When I first read the documentation for RTK Query, it immediately piqued my interest in a few ways:

Check out RTK Query since you are already using Redux.

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.

[1] https://orval.dev/

- 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.

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.

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.

wrote up the basics of our workflow few weeks ago https://betaacid.co/blog/api-contracts

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

This is a Library I've used in the past, https://github.com/anymaniax/orval

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.

On this page, we’ll use a code generator called Orval.
