React Hooks and the Evolution of State Management

In this post, I would like to share a brief history of ReactJS and its solutions to state management. You may probably know these already, but I think it would give a glimpse of how React evolves all the way long for those who are new to this framework, or a quick refresh if you are a veteran.

Two Camps of Components

React has two types of components — Class-based and Functional. As the names suggest, class components inherit React.Component and implement methods such as constructor and render for React to invoke, while function components are literally “functions” that take some inputs “props” and return the component to be rendered.

Prior to React v16.8, only class components can maintain a state and expose a handler to update the state. What’s more, there is a full set of methods to perform state management, side effects, and calculations at different time points throughout the component lifecycle. Class components can do everything you need to render a single-page application, even with performance optimization with thePureComponent, and it is the only way to do these jobs.

Function components, on the other hand, are pure functions that cannot have state and side-effects, but just rendering. One may call them “dumb components”, in contract to “smart components” that can contain much more business logic, side-effects, state manipulation, and controls on child components.

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.

What are hooks in React JS? - INFO AT ONE

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.

React State Management: Class vs Hooks Components

What is State?

In React, state is the relationship between data, rules you’ve given to the app, and what shows on the page. It can be broken down into five categories: model state, view/UI state, session, communication and location state. For example, if you are creating an e-commerce web application, here’s how to interpret each kind of state under this context:

  • Model State: The nouns (things) in your app, the list of your apparel (products), each individual product, the price/ description of those products that’s likely stored on the server. Model state is the thing that’s persisting in your application.
  • View/UI State: How is the list of products sorted (ascending/descending)? Is the list currently being filtered? We have the info of the product from model state, but how do we view it? Are we viewing the products by how popular they are? Or are we viewing them by their price from high-low? Unlike model state, information about UI state is not usually stored in the database but on the client-side of the app.
  • Session State: Is the user logged in? What kind of user are they? Are they a consumer user or an admin user? This determines what information they can see while using the app.
  • Communication State: Are we loading the app? Has it already loaded? Are we updating it? Was there an error? Are we in the process of fetching model state from the server? Communication state is the process of communicating with other kinds of state mentioned.
  • Location State: Where are we in the application (think URL)? Are we browsing products? Are we in the shopping cart? Are we on the checkout page?

Validating React Forms With React-Hook-Form

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.

Required Fields

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:
