Testing React Components: A Comprehensive Overview of Testing Libraries
Enzyme is another popular testing utility for React. It allows you to manipulate and traverse React components' output, making it easier to write comprehensive tests.

Speeding up the JavaScript ecosystem – Polyfills gone rogue
ljharb is an extremely interesting person. There’s no doubting the positive impact he’s had on the OSS community and the work he’s done.
However, there are some things he does that are incomprehensible.
For example, Enzyme. Over three years ago this issue was opened for Enzyme on React 17: https://github.com/enzymejs/enzyme/issues/2429
Nothing moved for a while, and I think he said something along the lines of “if you want React 17 support, stop complaining and help”. So the community got involved. There are multiple PRs adding React 17 support. Many unofficial React 17 adapters. A lot of people have put a lot of work into this, ensuring compatibility, coverage etc. Yet to this day, none of them have been merged. Eg https://github.com/enzymejs/enzyme/pull/2564
Given the amount of time that has passed, and the work the community has put in, something is amiss. It feels like he’s now intentionally avoiding React 17+ support. But why? I don’t understand why someone would ask for help then ignore the help when it comes in. That isn’t much better than the swathe of rude/entitled comments he was getting on the issue before he locked it.
I ended up migrating to RTL, but this made many of my tests more complicated (especially compared to shallow rendering).

How To Scale Your React Applications
One way to do this is by writing tests for your React components. Tools like Jest and Enzyme make it easy to test your component's behavior, rendering output, and state changes. By writing tests for your components, you can ensure that they behave as expected and prevent issues before they reach production.

Difference Between JEST and Enzyme?
Enzyme offers two types of API for shallow rendering and full rendering. Both are preferred for different test scenarios and functionalities.

Testing with Jest and React Testing Library
At Visa, I was writing unit tests for a Next.js project using components designed with Chakra UI. That's where React Testing Library came in handy. Unlike other solutions like Enzyme, I did not have to worry about the application snapshot but could instead focus on each UI element, its expected behaviour and the data it would render upon user interactions.

Superset: Testing and Enzyme to RTL conversion
Superset uses Jest and React Testing Library (RTL) to write unit and integration tests. In the past we used Enzyme, but now that we're currently converting all of our class components to functional components, Enzyme cannot support our testing needs. Since RTL is better for testing functional components, we're converting all of our test files to RTL. This can be quite a learning curve - I've gone through a lot of the process so I'd like to share what I've learned so far.

Build Dynamic Forms with React Hook Form
The idea here is to first define an array of field names for each provider. We'll also need a map with more detailed information about each field. This map will contain the field name, label, type, and validation options. We'll use this map to render the form fields and also to validate the form. Finally, we'll have a Form component that will render the form fields based on their type and handle the form submission. We'll use React Hook Form to handle the form state and validation.

React: A Mess That Shouldn't Exist In Web Development
Imagine someone unknowingly unleashing heavy computation on a component without useMemo. That computation will run on every component re-render. Not only that, The dependency array in your hooks (useEffect, useMemo, useCallback) are also checked in each re-render. It's like a double whammy for performance pitfalls! I know that you can avoid this by some technique like what react-hook-form done, but remember thats an extra complexity.

New client-side hooks coming to React 19
This will greatly simplify the handling of AJAX forms in React - like for instance for a search form. But again, this may not be enough to get rid of third-party libraries like React Hook Form, which does much more than just handle form submission (validation, side effects, etc).

UpsertDialog in React
We could consider to do all these steps specifically for each data-set; of course this isn't an efficient approach due to the amount of repeated code involved. So what if we could abstract all this in a single management? A way to do this could be using a simple configuration in which we specify each aspect for each input (its type, validations required and so on). And we can do this thanks to the extreme flexibility provided by React Hook Form.
