react-native-intl-phone-field VS why-did-you-render

I created a library that simplifies the validation and formatting process of international phone numbers: react-native-intl-phone-field. It's built using Google's library libphonenumber and phonenumber-js & it's not much by it's honest work.

Check out why-did-you-render. It may tell you some more information.

It's a combination of many things, but imo one of the worst is all the footguns regarding state and the rerenders they cause

It's so easy, that we monkey patch react to debug it https://github.com/welldone-software/why-did-you-render

Plus the vdom... Isn't great, the bundle size puts react at an inherit disadvantage, and the community has a knack for over reliance on bloated packages

When we implemented the MVP of the fintech app, we had a quite complicated form. At that time, I was still young and inexperienced. And eventually, we realized that our project was slowing down. We had to spend additional hours figuring out the reason. We had many unnecessary re-renders because we ignored basic rules related to props in React. I wanted to do everything possible to avoid such situations in the future. So, I added to the project linters like this and an additional starting configuration to package.json to run why-did-you-render. In short, this plugin issues a warning if something is re-rendered unnecessarily and suggests how to avoid it. Also, we included running Lighthouse in headless mode. Some people say that premature optimizations are bad, but for me, it's a principle: do it right from the start.
