react-query VS formik

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)

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

Additionally, there are more npm packages such as Formik and zod that come equipped with a range of features that can enhance the form validation process.

7. Formik and Yup

Forms are often tricky to get right with React. While there are great libraries like formik or React Final Form to do the heavy lefting for us, handling file upload still isn't always straightforward.

Formik is a well known React library that allows to create forms, manage, and validate their state. It comes with built-in support for Yup, a schema builder for value parsing and validation.

Formik is a small group of React components and hooks for building forms in React and React Native. Formik helps with the three most annoying parts: Getting values in and out of form state. Validation and error messages. Handling form submission. npm i formik

Formik

In the first part of this tutorial, we took a look at how to build React forms with custom HTML elements and form state and logic provided by Formik. In the second part, we switched to Formik components and build form with them. In this final part we will make another change, a small step back.
