Kingfisher VS react-query

The 3rd party library I use GRDB SwiftyUserDefaults Kingfisher SwiftDate Popovers

Saving URLs definitely the way to go. Would recommend using a library such as Kingfisher to do the image loading/ caching for you.

I also looked into this github library but wanted to first ask if anyone's had any experience using it.

You can checkout Kingfisher library (it downloads image, and caches it). Usage is fairly simple but I would recomment that you create extension for the UIIMageView, somthing in line like this:

In native iOS, most people use Kingfisher, and i'd love to have something as good as that on our RN app. Perhaps just some pure JS library that you could plug on the existing image component, and that would handle the saving-to-disk and fetching of the image?

Kingfisher - Download and cache images

We are using https://github.com/onevcat/Kingfisher for smooth image loading in collection view. If the image data are not in regular text file, how can we integrate CoreData's blob data with Kingfisher?

Make sure the proper target is selected in the Add to target in the dialog as shown above, then click Add Package button. The package should successfully be added to your project. Now following the same process, this time search for the Kingfisher package using the GitHub URL as the following https://github.com/onevcat/Kingfisher.

Kingfisher - A lightweight, pure-Swift library for downloading and caching images from the web. Language: Swift.

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
