A better alternative to useEffect

My experience with React hooks have been amazing. In this article, I will precisely talk on one of the most prominent hooks that we use on a daily basis which is useEffect.

I am assuming the readers coming to this article has good understanding on useEffect. If not, please first go through the concept at reactjs.org.

So essentially, useEffect react to changes in dependency list. They have replaced **_componentDidMount, componentDidUpdate, componentWillUnmount and componentWillReceiveProps in _**class based react components.

It’s very common to react to changes in props values or state values over the lifetime of a component. we also need to compare previous values and current values when reacting to changes often. In the class based component, we had componentDidUpdate for the similar use-cases.

It has following interface:

componentDidUpdate(prevProps, prevState, snapshot)

You have access to prevProps(previous props) and**_ prevState(previous state)_**, which can be used to make comparisons and react appropriately.

What about useEffect, how would you do those kind of comparison with them?

You can have a usePrevious custom hook which will always give you the previous value and that you make use in your useEffect to complete the comparison. Let’s see some code.

Notice, how usePrevious hook helps us by keeping a track of previous value. Now think about scenario, when there are more than one dependency in our useEffect. We need to make use of **_usePrevious _**hook that many times or we have to re-define our usePrevious hook to track an array of dependency.

Isn’t it too much of work every time ?

Android Vs iOS - Which is Better for App Development?

Welcome to our Android tutorial, in this tutorial, we are here with something that is a very hot topic of all time. In this article, we are going to discuss a very interesting topic that is Android VS iOS. We know that these days iOS is on fire, and so is Android. The growth rate of both the operating systems has been increasing rapidly for the last few years. Regardless of this, the growth of Android is found to be on the totally next level. So, we are very well prepared here to jot down the difference between Android and iOS

An Alternative to React's useEffect Hook

After spending almost three months working on a multistep form for one of my clients, I found that the existing react hooks are insufficient for creating a personalized form.

Just to give you a little bit of insight, my client wanted a seven-step form that included bullets on the left side for each form. The bullets had to be decoupled from the forms and needed a different color based on the state of the form.

The client also wanted that actions like coloring the bullets to be triggered only after the user leaves each form. When being unmounted, the form would send its state to another component.

Knowing that we were in need to create some custom solutions, we ended up implementing the following two hooks that saved us a lot of time. The first one is:

#useOnUnmount()

The useOnUnmount() hook is a functional React alternative to the ComponentWillUnmount lifecycle method that allows us to mutate values between renders so that it can be used outside the component. This hook saved us a lot of effort than just trying to change the business logic or installing other packages that might have helped us.

But why not just use the useEffect() return callback functionality?

If we go back to basics, the return function inside the useEffect() is a cleanup function, therefore we can't check a condition or set a new value for the state.

The hook looks like this:

https://codesandbox.io/s/useonunmount-sbttm?file=/src/App.js

Pay close attention to what value the console outputs inside the useEffect cleanup function and the useOnUnmount() hook.

How does it work?

useOnUnmount() uses a useRef() that allows the state to mutate between renders. The useEffect() will clean up the previous state before applying the next one.

#useOnUpdate()

This is another useful hook for when we want to trigger an action when the component state changes, and not when the component mounts. You can consider it the ComponentWIllUpdate alternative for functional React.

This one - calls the callback each time the state changes, triggering an action.

Why is this useful?

Well, imagine needing to trigger a modal, change the text on a button, etc., or any action you need - instead of keeping the logic inside the component, you can reuse it by having a custom hook.

The hook can be found here:

Hope this article will help you while developing forms in React and will ease your path.
