Top 4 Custom Hooks to Boost React application

Make your code cleaner and more reusable with custom React hooks.

After 9 months since the first stable release, React Hooks have changed the way frontend developers write React components. It’s a normal step in the evolution process of libraries like this, the introduction of new features decides which libraries and frameworks survive over others in the continuous race of frontend development. React was already a highly regarded frontend library, but with the React Hooks introduction, it made a big step.

Why React Hooks?

They help developers to keep control of side effects for our functional components without the need for using a class approach and lifecycle methods such as componentDidMount, componentDidUpdate, etc. Furthermore, they allow developers to share logic across components, reducing code duplication and human errors.

React has built-in hooks that provide functionality around the component control process, but the most amazing feature is the ability to combine them to create custom hooks and the ability for hooks to interact with the browser’s API.

There are numerous libraries that provide custom hooks, and some of those may handle the functionality we’re creating here and in a better way. However, it’s always good to see what happens behind the scene of functions that you already use every day! Let’s write our custom hooks!

usePrefetch

The usePrefetchhook can help you improve the loading time of the main app page by lazy loading other secondary components that don’t need to render on the first view. The goal is to reduce bundle size and make your application respond quicker.

For our example, let’s assume that we have a page with some information and a button that opens a modal. Before we press the button, the modal shouldn’t render and we don’t need it yet. But if we import it at the beginning of the main component, we will need more time to download its JavaScript code because it will be included in the original bundle. What we want to do is lazy load the modal component to split its code from the main component and prefetch it when the main component has rendered the first time.

Q.A. Why do we define an **importModal** function? Because if we write the import inline, it will happen every time a new function is called, and it will run the useEffect inside the hooks on every render.

useGeo

This hook gets the current position and the updated value whenever the user moves:

Q.A. Why do we define an **isLoad**variable? Since getting the position is an async operation, it is possible that your component re-renders. So we run the cleanup function before it effectively retrieves the location. With this workaround, we can prevent running the onSuccess or onFailurehandlers if the component has been unmounted too soon.

useInterval

The useInterval effect is probably the best known custom React hook, but here I’ll show its implementation by Dan Abramov since we’ll use it for the next hook:

useTimer

Occasionally developers face the need to implement an efficient way to get a countdown timer, so let’s create a countdown timer starting from a timestamp that represents the amount of time we want to countdown in milliseconds:

Comments, shares, and discussion about the topic are always appreciated and I’ll be glad to answer any of your questions!

Thanks!

How native is React Native? | React Native vs Native App Development

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.

A brief introduction to React Native

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:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

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:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

The Ugly Side of React Hooks

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.

Motivation #1: Classes are confusing

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

thiscould 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 anifstatement, 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.
