SWR is a React Hooks library for remote data fetching.
The name “SWR” is derived from stale-while-revalidate, a HTTP cache invalidation strategy popularized by RFC 5861. SWR first returns the data from cache (stale), then sends the fetch request (revalidate), and finally comes with the up-to-date data again.
It features:

Building Todoist from Scratch Using React (Custom Hooks, Context), Firebase & React Testing Library
This application (a Todoist clone) was built using create-react-app as a base, and the technologies used were React (Custom Hooks, Context), Firebase & React Testing Library. I’m hoping this gives people a better understanding of React, and I’ve also included SCSS in this tutorial, but the main focus is to build a real application using React! If you clone this application, click the Pizza icon on the top right, it enables dark mode!
Subscribe to my YouTube channel here: http://bit.ly/CognitiveSurge where I build projects like this! And don’t forget, you can contribute to this project (highly encouraged!). One thing I didn’t get time to do was incorporate accessibility into this application, so I’d love to see that added!

React Hooks were introduced in version 16.8.0. They are a complete departure from class component lifecycle events. For more information, see the official React Hooks API Reference.

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.
Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

In this article, you will learn what are hooks in React JS? and when to use react hooks? React JS is developed by Facebook in the year 2013. There are many students and the new developers who have confusion between react and hooks in react. Well, it is not different, react is a programming language and hooks is a function which is used in react programming language.

While coding this week, I had to convert one of my class components in React to a functional component.
Why would I need to do that? After all, the parent component sees the two types of components as identical. Sure, functional components can be shorter, require less boilerplate, and maybe even perform better. But that’s not why I needed to do it. I was using an npm package that had React hooks and hooks are for functional components only. React Hooks, added in React 16.8, allow functional components to manage state and replace lifecycle methods. To use the hook I needed I had to convert my class components to a functional.
Here are the steps I followed to change my class component to a functional component:
#react-hook-useeffect #useeffect #react-hook #react-hook-usestate #react

Validating inputs is very often required. For example, when you want to make sure two passwords inputs are the same, an email input should in fact be an email or that the input is not too long. This is can be easily done using React Hook From. In this article, I will show you how.
The most simple, yet very common, validation is to make sure that an input component contains input from the user. React Hook Form basic concept is to register input tags to the form by passing register() to the tag’s ref attribute. As we can see here:
#react-native #react #react-hook-form #react-hook

In this post, I will share my own point of view about React Hooks, and as the title of this post implies, I am not a big fan.
Let’s break down the motivation for ditching classes in favor of hooks, as described in the official React’s docs.
we’ve found that classes can be a large barrier to learning React. You have to understand how "this"_ works in JavaScript, which is very different from how it works in most languages. You have to remember to bind the event handlers. Without unstable syntax proposals, the code is very verbose […] The distinction between function and class components in React and when to use each one leads to disagreements even between experienced React developers._
Ok, I can agree that
this
could be a bit confusing when you are just starting your way in Javascript, but arrow functions solve the confusion, and calling a_stage 3_feature that is already being supported out of the box by Typescript, an “unstable syntax proposal”, is just pure demagoguery. React team is referring to theclass fieldsyntax, a syntax that is already being vastly used and will probably soon be officially supported
class Foo extends React.Component {
onPress = () => {
console.log(this.props.someProp);
}
render() {
return <Button onPress={this.onPress} />
}
}
As you can see, by using a class field arrow function, you don’t need to bind anything in the constructor, and
this
will always point to the correct context.
And if classes are confusing, what can we say about the new hooked functions? A hooked function is not a regular function, because it has state, it has a weird looking
this
(aka_useRef_
), and it can have multiple instances. But it is definitely not a class, it is something in between, and from now on I will refer to it as aFunclass. So, are those Funclasses going to be easier for human and machines? I am not sure about machines, but I really don’t think that Funclasses are conceptually easier to understand than classes. Classes are a well known and thought out concept, and every developer is familiar with the concept ofthis
, even if in javascript it’s a bit different. Funclasses on the other hand, are a new concept, and a pretty weird one. They feel much more magical, and they rely too much on conventions instead of a strict syntax. You have to follow somestrict and weird rules, you need to be careful of where you put your code, and there are many pitfalls. Telling me to avoid putting a hook inside anif
statement, because the internal mechanism of hooks is based on call order, is just insane! I would expect something like this from a half baked POC library, not from a well known library like React. Be also prepared for some awful naming like useRef (a fancy name forthis
),useEffect ,useMemo,useImperativeHandle(say whatt??) and more.
The syntax of classes was specifically invented in order to deal with the concept of multiple instances and the concept of an instance scope (the exact purpose of
this
). Funclasses are just a weird way of achieving the same goal, using the wrong puzzle pieces. Many people are confusing Funclasses with functional programming, but Funclasses are actually just classes in disguise. A class is a concept, not a syntax.
Oh, and about the last note:
The distinction between function and class components in React and when to use each one leads to disagreements even between experienced React developers
Until now, the distinction was pretty clear- if you needed a state or lifecycle methods, you used a class, otherwise it doesn’t really matter if you used a function or class. Personally, I liked the idea that when I stumbled upon a function component, I could immediately know that this is a “dumb component” without a state. Sadly, with the introduction of Funclasses, this is not the situation anymore.
