Why Should You Use React Redux?

As the technology advances, users expect more advanced features and improved performance to the software they are using. Every month new framework, tool, libraries came to the market for web development. But it is not a sensible thing on your part to jump on every single one of them without knowing their benefits. Though redux is not a new concept, it is nevertheless quite popular. Here we’ll discuss all about react redux, and Why you should use React Redux?

What Is Redux?

Redux has been created to help you write javascript apps consistently across server, client and native environments. It is mostly used as a state management tool with ReactJS development services and can be used with other javascript libraries or frameworks. It is a lightweight and hence there is no need for you to be concerned about it making the asset size of your app larger. Your app’s state is kept within a astore with Redux and every component can access any state required by it from the store.

Advantages Of Using Redux-

1. Simple Debugging And Testing-

Redux DevTools can be used for better understanding of what is taking place in the application.

2. Hook Monitoring Tools-

It can be possible to hook monitoring tools to the state of app to monitor in real-time. This will improve your app’s visibility, and you can monitor different metrics.

3. Predictable Results-

Each action generates a predictable result. State store works as a sole source of truth. So it is possible for you to stay away from data inconsistency faults and you need not be concerned about data synchronization issues between components.

4. Rapidly Test Reducer Functions-

Reducer functions happen to be your functions, and accordingly, they will deliver the identical output for the identical input. Subsequently, it is easy to test unadulterated capacities. Consequently, it is easy to test pure functions.

Why Should You Use React Redux?

1. Community-

React Redux is supported by a huge community of users. This makes it quite easy to ask for help, use libraries building on top of Redux, understand most effective practices and use your knowledge in various app development.

2. Redux UI Bindings-

While it is possible to use Redux with any UI layer, it was initially intended for React use. You’ll come across UI binding layers for many other frameworks, but the redux team is responsible to maintain directly React Redux. 

As React’s official Redux binding, React-redux is updated with any changes in API from both libraries to ensure that React components behave as expected. Design principles of React are adopted by its intended use, that is creating declarative components. 

3. Optimizations In Performance-

Despite the fact that React is fast, any update made to a component will make it render every component within that part of the component tree again. It requires some work and if there is no modification in the information for any particular component, then re-rendering will be wasted as there will be no change in requested UI output.

One of the best way to improve the performance will be to avoid unwanted re-renders like components re-render only when their data has been modified. Various performance optimizations are implemented by React Redux internally so that component re-renders only when it is imperative to do so.

Additionally, you will ensure that each connected component just extracts the specific snippets of data from the store state required by that component by connecting a few components in the React component tree. Meaning that it will be imperative to re-render your component less frequently since, on most instances, those specific parts of information have not been changed.

When Should You Use Redux?

In the front-end world, there is a significant debate regarding the redux. Many individuals preferred it but some others criticized it. 

Redux allows you to manage the state of your app in one place and keep the modifications in the app as easily traceable and predictable. Such a way, it becomes simpler to reason about modifications taking place in the application. But all those advantages come with constraints and trade-offs. For instance, it has been seen that Redux is responsible to add boilerplate code that helps in making simple things somewhat overwhelming. But, it significantly depends on architecture decisions. Simple reply to this query is that you will understand it for yourself once you require redux. 

In case you are still confused whether you need it, there is no need to do so. This happens when your app will develop to the scale where it will become difficult to manage the app state, and you will be starting to search how to make it simple and easy.

When Should You Not Choose Redux?

If you’re a beginner, it will be a good decision to go with Redux. Applications that have simple UI changes will not need a complicated pattern like Redux on most occasions. But outdated sharing of state between various components works very well and improves code’s maintainability.

If the data is derived from one data source in each view, you can avoid use of Redux. If you don’t require data from multiple sources, it is not necessary to introduce redux. Because it will not result in data inconsistency problems while accessing one data source in each view.

Also, ensure to verify whether you need redux prior to applying its complexity. Keep in mind that, Redux happens to be in-memory state store. Meaning that you will be losing the complete app state if the app crashes. Also, it means that you need to use a caching solution to create a backup for app state, that will create extra overhead.

Best Practices For Redux-

Here are some best practices to follow while building large scale applications with React and Redux.

• Differentiate Presentational Components and Container Components.
• Use bindActionCreators for dispatching actions
• Try to avoid using setState and component lifecycle hooks when using Redux
• Using .bind() in best way
• Use Accessor Functions
• Write cleaner code using ES6 Features
• Use Flow Types
• Use axios library for http requests over jQuery ajax
• Test your React components
• Use styled-components to style your components
• Use ES Lint for better coding conventions.

Wrap Up-

Though react redux is not that much new, but still most of you get confused about whether to choose it or not. Hence here we came with a detailed information about React Redux, its advantages and when to use it or not to use. If you are going to develop app and confused about Redux, this blog will surely help you in your best decision.

React Best Practices To Follow In 2021

 

React is a well known open-source JavaScript library that is used to create unique and innovative applications. It was created by Facebook and allows integration with many exciting components, libraries and frameworks. Also, developers can make their own components. Developing an app with React is not as simple as it looks. Knowing the react best practices will help you to develop an effective app within less time. Still, if you are not aware of the react best practices, then this blog is for you. Let us see the React best practices.

React Best Practices To Follow In 2021-

1. Project Structure-

1.1 Folder layout-

Architecture mainly focuses on reusable components of react developer architecture so as to share the design pattern among multiple internal projects. So the component-centric file structure should be used that means all the files related to a different component (Javascript, assets, CSS etc.) should be kept under a single folder. 

Components
	|
	--Login
		|
		--tests--
		--Login.test.js
		--Login.jsx
		--Login.scss
		--LoginAPI.js

This one is another approach used in grouping the file types. In this, the same type of files is kept under one folder. Here, same type of files is kept under one folder. For instance,

APIs
  |	
  --LoginAPI
  --ProfileAPI
  --UserAPI

Components
  |	 
  --Login.jsx
  --Login.test.js
  --Profile.jsx
  --Profile.test.js
  --User.jsx

Above structure is the basic example. The folders can be further nested based on requirements.

1.2 Css in JS-

In huge projects, theming and styling can be challenging tasks like maintaining nig scss files. Hence, the concept of CSS-in-JS solutions comes into focus. Following libraries are based on it-

• EmotionJS
• Styled Components
• Glamorous

Among those libraries, you can use as per your requirement such as, for complicated themes, you can select styled-components or Glamorous.

2. Coding Style Best Practices-

2.1 Naming Conventions-

When you work with React, generally you are using JSX(Javascript extensions) files. A component that you create for React should be named in Pascal case, or upper camel case. This translates to names without spaces and capitalizing the first letter of every word. If you have to create a function that submits a form, you should name it SubmitForm in upper camel case, instead of SubmitForm, submit_form. Generally, Upper camel case is called the Pascal case.

For globally used Constant fields in the application, try to use only capital letters. For example, PI = “3.14”;

2.2 Avoid unnecessary DIV-

When there is a single component to be returned, no need to use <div>.

return (
   <div>
   <Button>Close</Button>
   </div>
);

Whenever there are multiple components to be returned, use in shorthand form <> as below-

React Vs Vue: Which One To Choose In 2021?

 

These days web applications are ruling the development landscape and will continue in the future too. When it comes to choosing Javascript frameworks and libraries, developers came up with many options including React and Vue. The challenging part is deciding to use Vue or react for use  in your tech stack. Both use a Virtual DOM and possess a reactive and component-based structure. Here we will compare two very popular web app frameworks React and Vue on the basis of various parameters such as, user-experience, performance, testability, security, developer availability and so on. Before digging to the comparison, let us see each one in detail.

React-

React.js is an open-source javascript library used to build web apps with rich user interfaces. It offers flexibility to create reusable custom components that encourage rapid development processes. Also, it is user friendly due to its ability to allow quick rendering of a web page. This library promotes the development of light-weight and complex business applications.

One can create not only web apps with React.js, but also media sites, video streaming platforms, software as a service tools, mobile apps, desktop apps, progressive web apps, JAMstack sites etc. Paypal, BBC, Facebook, Netflix, Twitter are some of the examples of popular apps created with React.

Vue-

It is a lightweight and flexible JavaScript-based framework that provides advanced web tools to develop modernistic SPAs and front-end web apps. Vue is also considered a versatile and progressive JavaScript framework because it allows change creation in an application code without influencing any core feature built and this provides an opportunity to create progressive UI. With decoupling, Vue also offers opportunities to extend functionalities of web app with customized modules and visual components.

Know the advantages of reactjs for building interactive user interfaces at- 7 Advantages of ReactJS for Building Interactive User Interfaces.

One can create single-page apps, progressive web apps, small project apps, large scale enterprise apps, existing app design extension, existing app functionality extension with Vue. Behance, Gitlab, adobe portfolio, laravel spark, grammarly are some of the apps created with Vue.

React Vs Vue- A Comparison

1. Learning Curve-

React-

React adopts the JSX format, where HTML is written in JavaScript. Though JSX is inline with functional programming, developers are saddled with the responsibility of figuring out this new approach. React heavily depends on other third party components for effective use. This can be an issue for developers since they news to grasp a lot of information just to get things done. React has a good documentation.

Vue-

Vue is easy to learn as compared to React. It separates concerns so that web developers are already used to, decoupling HTML, CSS and JavaScript. Vue allows the use of JSX for those who want to adopt that style. It is easy to get accustomed with Vue because it picked out the good parts of React and Angular. So it is easy for developers from either of the two backgrounds to fit in perfectly. Vue has a well detailed documentation.

2. Performance-

React-

React app’s performance is faster, a lightweight performance in user experience with individual components working in a fine functional way. It’s component based architecture helps to build more robust single page apps, reusability removes code clutter and reduced DOM manipulation speeds up the page loading. This reflects seamless app performance and pleasing user experience. Library works on updating the necessary changes to the webpage without reloading the entire page. Hence it eliminates the unnecessary loading of page and rather refreshes the data. To build react apps by setting some programming practice, you can use minimal approach.

Vue-

When each new feature added or extension of a component, Vue app becomes more uncertain that makes it hard for the app to load faster. Whereas, this framework has a virtual DOM, that serves as the default tool which helps in app’s performance optimization. Lazy loading feature of Vue helps to improve load time. Vue deals with third-party library in an asynchronous way by automatically handling the critical dependencies by isolating the libraries into the ones that need to be included in the main application bundle and the ones that can be left in routes away from the core bundle. 

3. Architecture-

React-

It doesn’t have a built-in architecture pattern. React caters to the view layer of app which is made with components. React components work as functions that render the underlying user interface as data changes. Continuous interaction between the users’ actions and state of app components makes internal architecture of Recat.js. The state of the React component is excellent when you need to build applications with limited functionality and scope. React is dependent on external libraries such as Flux, MobX, Reflux, Redux for building real-world applications.

Vue-

It follows the ViewModel approach and supports the pattern on MVVM in case of developing large-scale apps. View part and Model part are connected in two-way binding.

Model- Functions like Model object of JavaScript. When the data object enters the Model part, the data instance is transformed into reactive elements to create appropriate storage layers discretely.

View- There is a management of DOM instances in the View part of Vue. It makes use of DOM-based templating to successfully creating root elements and correspond with required DOM components.

Viewmodel- It handles the synching necessity between Model and View part of code. This Object is the primary part to interact developers with code.

Architecture of Vue and its DOM structures are abstracted into parts- Filters and Directives. Vue is not a full-blown framework so it follows a View layer pattern, handling of app development is made simple and flexible.

4. Scalability-

React-

React apps are made up of pure javascript so developers can depend on traditional easy to organize the code to make projects more scalable. This is a good framework for building scalable UIs pertaining to the concept of virtual DOM and component reusability.

Vue-

Vue is preferred for developing small-time apps and not scalable apps regardless of its ability to extend app with its flexible tools. Scalability can be made possible by forking a vue app by breaking it into multiple multiple repositories to separate the app for convenient scaling as per requirement. As the architecture is little dynamic, scalability is achieved by using web packs and Mixin elements offered by Vue to override the code extending limitations.

5. Application Size-

React- 

It is a library and not a fully featured frontend framework like Angular. React’s app sizes are bigger as compared to other. Latest react versions have reduced bundle size by reducing app size by 30% to previous version.

Also know- Most Common Mistakes To Avoid In React Development.

Vue-

It is a lightweight framework and so its app size might not be heavy like other frameworks. A simple Vue app has a size of between 50kB to 100kB. Vue CLI might make the app size appear large when it loads the code for first time due, but implementing lazy loading components, codes can be broken into smaller parts and improve load time. Tools such as NuxtJS, Vuex, Bit, Vue-router eliminate the need of code writing from scratch with effective state management that predicts unnecessary functions, codes and eliminates them.

6. Code Maintenance-

React-

We know that react has component based architecture and it concentrates on building UI components, custom functionalities in user interface and optimally using logic to build functionalities. While developing app with React, you are developing functional and individual code snippets. Those snippets are reusable to other apps and various modules of the app. Dividing app into specific parts helps to manage app efficiently. 

Vue-

Vue is ever-growing technology and is rising in pace against most frameworks that have existed for a long time. So maintaining a Vue app is not that much hard. Vue lacks good support, creating conventional coding practices help to overcome limitations and obstacles. Vue is future-proof considering its effortless integration abilities and code grafting continuity onto existing DOM and HTML mark-up with zero prerequisites.

When To Choose REACT?

• You can choose react when you want to play around with many libraries, tools or ecosystems.
• Prefer React to develop scalable apps without any hassle for testing and debugging.
• Go with React to build complex app with better time-to-market.
• You can build video streaming platforms and media sites effectively with React.

When To Choose VUE?

• You can prefer Vue to build progressive web apps and single page apps.
• Also, if you want to extend the functionality of existing apps, go with Vue.

Final Words-

The above comparison will surely help you to choose the best one between React and Vue. If you are still confused to choose the best one, consult with solace experts. We are here to help you through consultation and development with experts skilled in modern technologies.

Most common mistakes to avoid when creating a react native app

Applications have taken over our lives. According to Statista, more than 204 billion applications have been downloaded in 2019. It means the application industry is thriving, and many states that it will keep growing later on also!

As an ever increasing number of individuals use smartphones and thus applications, the industry has become a quiet advantageous opportunity for new entrepreneurs. Many wish to become wildly successful in the sector by developing the best application out of the lot.

But, application development is easier said than done!

The primary choice you should make as a developer is which programming tool to use to create a smooth and glitch free application. One alternative you should think about is to use React Native.

Why React Native?

React Native is a mobile application development framework that is developed by Facebook. It is an open-source platform that was launched in 2015.

Compared with all different cross-platform application development frameworks, React Native has proven to be the most preferred by many developers. This is because it allows developers to create an excellent quality application for the iOS and Android simultaneously!

Here are some basic advantages related with React Native:

• It uses JavaScript which almost every developer knows inside and out
• The React Native Framework has a very straightforward installation process
• The live reload feature of the platform allows for a rapid application development
• It is a cross-platform, in this way allowing developers to create solutions that can be adapted to Android, iOS, VR devices, smart TVs, and so on.

Mistakes to Avoid When Developing React Native App-

Here are the most well-known mistakes that an application developer can make when developing an application using React Native.

1. Wrong estimation- 

Layout for iOS and Android version – there will be various reusable components, however there could also be various layouts. Actually, the insignificant structure of an application page can be totally different on iOS and Android.

Forms – you should estimate the validation layout too. At the point when you create an application in React Native, you should write more codes compared to when you create a Hybrid application on suppose Cordova.

If creating Web application – You should check all the various endpoints which are offered by the backend. Also, because you should deal with the logic in the application, it should all be coded accurately. You should understand the database structure, how the entities are connected, and so on.

2. Wrong redux store planning-

Why you should choose ReactJS for your next project?

Facebook introduces ReactJS, which is an open-source platform that optimizes JavaScript library, allowing you to develop interactive interfaces for single-page applications. The objective of ReactJs web development is to provide rendering functionality, and this happens because the framework focuses on separate components. Rather than working on the complete website application, ReactJs allows developers to communicate complex UI into reusable and more accessible components. This was first applied on Facebook in 2011 and afterward in 2012 on Instagram!

Without reloading website pages, developers can make positive changes in web application data. These features are quite simple, rapid, and efficient in building an interactive UI for applications. And hence, developers can use another JavaScript framework like Angular as it consists of great groundwork and an active community behind it. Facebook has built this front-end library.

Why choose ReactJS for your next project?

ReactJS Development

1. Easy & Simple to Learn-

When compared with some other framework, ReactJS is very clear and sophisticated. It is easy to understand. This makes the developer’s work easier as they can use JavaScript just for developing web applications. You can also merge HTML with it through some of its syntaxes. Also, JSX is simpler to use with it.

2. Data binding & Code reusability-

React can create web applications for both the platforms and support the code reusability. It also enhances one-side data binding and fluxes the application architecture to control the data flow from a single point. This feature is helpful for web application development and can help developers to a great extent.

Also know- How you can Boost Your Web Application Performance?

3. Single way data flow-

React boosts the way of data flow in which a few values are approved as components and rendered as properties in the HTML tags. It limits the access or change components directly, but approves a call back that performs this task. This property is about activities streaming up and properties streaming down. This property is about actions flowing up and properties flowing down.

4. Testing & functionality-

One can use the ReactJS framework for browsing ecmascript6 modules that describes dependence and can use it with Babel, reacts-di, and so on. These are easy to test and can be treated as the present state’s function. They can be observed from the triggered functions, events, output, and so on. You have to test before using it, and ReactJS surely makes it very simple to do it.

5. Virtual DOM-

ReactJS development services make the components of memory data structures, which compute amendments and updates the browser. Hence, a strong feature is empowered that helps the developers in coding, and it renders the components, renders, and data that can be processed and used.

Some More Reasons to Go with Reactjs.

Comfort and speed-

At the point when you use separate components on the server, it increases the speed of development. Hence, many people or teams can write each and every part whenever required, and this change in the website won’t cause rewriting of all the logic again.

Supportively, Material-UI also offers React themes and templates, so you can have a custom color theme  for your application.

2. React bootstrap-

Do you remember the previous bootstrap library? It was really a mix  of CSS and JS files, which allowed you to easily include pre-styled and pre-programmed UI components. What better match, then, than bootstrap and react? This specific library deals with bridging gap between the old and the new ways by bringing the power of React to an effectively great library. All that you could do with Bootstrap is- you can do it with this other option, the main difference is that you’ll be following the React components pattern. If you were a user, you’re looking to rapidly improve your CSS/JavaScript skills; at that point you’ll need to double check this alternative. Analysis: React Bootstrap’s GitHub project has over 16.7k stars and is being downloaded from NPM over 470k times each week. This means that it’s very famous!

3. Material Kit React-

Material Kit React is created with motivation from Google’s material design, Material Kit React builds a lot of elements that put consistency as the primary feature. That way, your web project holds a similarity in appearance and functions all through. The general design looks like multiple sheets of paper. This imparts a depth and order to the layouts. Three example pages are included. These pages represent what’s conceivable with this kit, they also serve as templates where you can substitute content and pictures with your own.

The kit contains various essential elements such as, buttons, badges, sliders, menu, pagination, navigation bars, tabs and pills. You can customize the style, size and color for most elements. The JavaScript elements include Modals, tooltips, date-time picker, carousels and popovers. Other than using the kit to start another project, you can also restyle any old Bootstrap project.

Most Common Mistakes To Avoid In React Development

Some mistakes have become common among developers working on React applications. These mistakes might be the result of an oversight, pressure to meet a deadline, or an absence of experience with React/JavaScript. Here you came to know with some common mistakes that you should avoid in react development.

Most common mistakes to avoid in react development–

1. Not creating enough components-

One mistake that React developers frequently make is that they don’t create enough components. Generally, there are two different ways of writing applications: putting everything in one place (monolith), or partitioning everything into smaller pieces (micro-services). To build this dashboard effectively with the use of React, we have to consider it as a set of components that form a page instead of an entire page itself. That way, we can create various sets of components that — when assembled — make up the entire page. This technique saves your time, however it also saves you a lot of stress while debugging since you’ll instantly know which component is associated with each error.

2. Writing logic in components-

While looking for an appropriate method to create components for reusability, the presentational and container component creation pattern is often one of the first to appear.

Presentational components are related with how things look, while container components are related with how things work. A common mistake you’ll see in React applications is that presentation markup and application logic are fused into one component. The drawback of this approach is that you cannot easily reuse any of the components or logic without copying and pasting. If you use the presentational and creation pattern, you can achieve reusability of both the markup and logic more effectively. You can also make UI changes without messing up the behavior.

Let us see the components below:

This is a component that is just needed to get data from props and show it. It is a presentational component.

const Books = props => (
  <ul>
    {props.books.map(book => (
      <li>{book}</li>
    ))}
  </ul>
)

This books component manages and stores its own data, and uses the presentational component books above to show it.

class BooksContainer extends React.Component {
  constructor() {
    this.state = {
      books: []
    }
  }

  componentDidMount() {
    axios.get('/books').then(books =>
      this.setState({ books: books }))
    )
  }

  render() {
    return <Books books={this.state.books} />
  }
}

3. Mutating state variables

Mutation is the ability to change something. Consider the following state:

const person = {
   name : "John",
   gender  : "Male",
}

If you create a new variable in your application at some point and assign the person object to it with the aim of changing it, you might be shocked by the result:

const newPerson = person
newPerson.name = "Jane"
newPerson.gender  = "Female"

If you attempt to log both the person and newPerson object, you’ll see that both now reflect the most recent value that was set. This frequently clarifies unusual component behavior. To solve this, you can use the .slice() method or the ES6 spread administrator ES6 spread operator.

However, the best approach is immutability. You can either implement it yourself, or use Immutable.js and immutability-helper, which is recommended by the React team.

4. Not using absolute paths-

If you have ever worked on a React application that has numerous components, images, CSS files, and other files, you’ll agree that importing files from various directories can be tedious. Commonly, we’ll import files this way:

../../../importone.js
../../../importtwo.js

We have seen that it isn’t neat, and changing the directory of a file will cause the import to fail. With the release of Create React App 3, we would now be able to utilize absolute import paths. To do this, create a jsconfig.json file in your root directory with the following:

// jsconfig.json
{
  "compilerOptions": {
    "baseUrl": "src"
  },
  "include": ["src"]
}

Now, you can import your files this way:

import React from 'react';
import { LINKS } from 'helpers/constants';
import Button from 'components/Button/Button';

function App() {
  return (
    <>
      <Button>
        This is my button
      </Button>

      <a href={LINKS.ABOUT}>About Us</a>
    </>
  );
}
export default App;

Not only is this cleaner, however it also implies you don’t have to update the way in your code after changing the location of a file. Get familiar with CRA V3 here.

5. Not using key on a listing component-

We regularly run into situations where we would need to render a list of things. The code seems to be like this:

const lists = ['one', 'two', 'three'];

render() {
  return (
    <ul>
      {lists.map(listNo =>
        <li>{listNo}</li>)}
    </ul>
  );
}

For smaller applications, this may work. When working with enormous lists, you’ll run into render issues when you attempt to modify or delete an item from the list.

react monitors each of the list elements on the DOM. Without it, it would not know what has changed in the list item. To fix that, you have to add a key to all your list elements like below:

<ul>
  {lists.map(listNo =>
    <li key={listNo}>{listNo}</li>)}
</ul>

6. Not writing unit tests-

This is one of the most well-known mistakes out there. It’s frequently overlooked because applications can still technically work without unit tests. A unit test enables you to test parts of your application freely to ensure a specific functionality works as expected.

For example, you can write a unit test to check if a prop went to a component was rendered on the browser. You may wonder why you’d write such a small test. Some of the time you expect your prop should show appropriately after writing your components, yet occasionally a conflicting CSS style may block it from displaying. 

Writing a unit test saves you the time you’d spend finding that bug by pointing it out immediately. They assist you with debugging rapidly across your application.

7. Not using prop-types-

We regularly observe incorrect data types being passed around in applications. For instance, say you need to pass a number 2 by means of props to another component. Frequently, you’d see it done like this:

<MyComponent value="2" />

This sends the value 2 to MyComponent as a string rather than a number. To send it as a number, write it like follow:

<MyComponent value={2}/>

Defining the types via the prop-types package is the most reliable method for ensuring you send the correct props.

Prop-types are used to document the intended types of properties passed to components. React will check props passed to your components against those definitions, and warn in development if they don’t coordinate.

8. Not using helper classes or functions-

This is most common mistake noticed in many React applications.

Also to reusable components, we also have reusable functionalities in our applications. This functionality is frequently hardcoded on a components to component basis, which prompts inefficient and inconsistent behavior between similar components.

All container components contain logic to get a resource, save it to state, and deal with errors. Many times, this behavior is the same from one container component to another, however it can act inconsistently when not written appropriately. 

Consider the above example where we make an API call to get a resource, set the state, and also handle errors.

If we extract that behavior to a helper class or function, we can reuse a similar logic for API calls, setting state, and error handling.

9. Using Redux or Flux to manage all your application states-

In greater React applications, many developers use Redux or Flux to manage global state. This is extremely helpful, particularly when different parts of the application will benefit from having a shared state.

In any case, it’s inadvisable to utilize Redux or Flux to deal with each state in your application.

Take, for example, a form components. If we need the state of a check button to consistently be checked whenever we visit it, the best approach is to manage it using local state method or useState (for Hooks) instead of using Redux or Flux.

10. Not using React and Redux dev tools-

Applications consistently get buggy after a while. Debugging is regularly a great deal of work, since most of the time many components are involved. With React dev tools, you can assess the rendered tree of React elements, which is incredibly helpful for seeing how different components build up a page.

The Redux dev tools likewise accompany a host of features that let you see each activity that has occurred, see the state changes these actions caused, and travel back to before specific actions occurred. You can include React dev tools as either a dev dependency or as a browser extension. Using them will save you a great deal of development time.
