fquery VS react-query

Similar benefits without codegen (based on decorator magic) for a python based stack:

* Use dataclasses for both database schema and the user facing operations

Re: Conways law at Facebook

I was at Facebook when GraphQL was invented, maintaining a backend storage service where a core assumption was that storage should be reorganized based on access patterns and that predicates should be pushed down to storage where they can be executed more efficiently.

GraphQL was hard to push predicates down, because you don't know which of the edges were written in PHP.

My response was fquery[1], which is like what's being discussed here but with python as the source language instead of swift and amenable to preserving the largest possible query structure for backend optimizers, including SQL optimizers.

It has some early demos converting a GraphQL/fquery into SQL where possible. It should be possible to add enough metadata to fquery to identify if an edge is non-trivial (calls into another microservice) or trivial (can be optimized to a storage backend or SQL).

react-query

React Query: This library makes it easy to manage data in your React applications, from fetching to caching and updating data. It offers a simple, powerful, and flexible API for handling data and keeping your UI in sync with your data. https://github.com/tannerlinsley/react-query

useQuery (react-query) (+) all from above (+) even more features (-) more complex, even the examples are complex, has more aggressive defaults (re-fetching every 2s)

see here Overview

Rapini is a new tool that can generate custom React Query hooks using OpenAPI (Swagger) files.

React Query is the gold standard for using async data declaratively with hooks. I ended up needing to modify even my simple useTimer hook to work more like useQuery to take multiple keys in order to work as an inner observable for other operators.

For most situations, I would recommend using a library like React Query. It handles a lot of common data-fetching boiler plate and already accounts for this useEffect() issue. Also, it supports Suspense if you want to use that.

At this point, I want to move on to the react-query cache management library. Give a brief overview and see how you can improve your developer experience with cache using this library.

There isn't the "service" concept in React. If you need to send off data you can just do so with fetch. If you need to load data and cache it so it can be used across components and unmounts, then something like react-query is what I'd recommend. But it's basically a combination of React Context, useEffect, and useState to manage the cache and lifecycle of a request.

react-query is pretty neat too. I default to that for most projects unless it's something unusual
