1. Best Practices to Ace ReactJS Web
Development!
Applications are the crux of every business. Whether you have a food business or
a logistics business, an app makes it easy for you to interact with your customers.
Moreover, it also widens your business scope.
One of the key elements that make an app successful is its UI. 52% of the users
say that they won’t return to a website if it does not look good. Therefore, to make
users stick to your app, you need to build a stunning UI. For that, you will need the
best tools on the market. ReactJS is one such tool that helps you create highly
attractive user interfaces.
ReactJS has some brilliant features that help you get better UIs and in less time.
Many of you might be super proficient in coding, but if you are not, this article is
for you.
To make efficient and performing apps, there are numerous tips and tricks that
you can use. We will discuss all of those tips here in the article. We will also
uncover some brilliant security features of ReactJS.

2. Best Tips and Tricks to Use ReactJS!
If you are looking for some type of instant solution here, it’s not going to happen!
Though these tips will be helpful for React web development, they will not create
something stunning overnight. You need to do some hard work for a good app.
Folder structure
Every book has an index page in the beginning, right! Well, the folder structure in
ReactJS is also similar to that.
If your Reactjs development company is designing a big app for a client, it is
best to keep all the app modules arranged. As there can be countless modules in
an app, a well-sorted list will be the best option if you want to reuse them or
remove them entirely.
In ReactJS, you can divide your entire app into feature modules. There are various
benefits of this such as:
● You won’t have to change the entire app if there is an error in any module as
they all are isolated from each other.
● Thanks to the isolation, the code is super easy to maintain.
● The lazy loading feature can be of great use as you can load individual modules
instead of an entire page.

3. In addition to this, you can choose to keep files in a folder under various
combinations. For instance, you can keep the same type of files under one folder,
such as LoginAPI, ProfileAPI, UserAPI, etc., files under the APIs folder.
You can make various other arrangements based on your needs and preferences.
The key aim is to make the app development process efficient.
Don’t make new components
This does not mean that you entirely stop making new components. The crux is
to ensure that you do not make new components for every function you repeat in
the program. If you come across a component you have used in the program
before, reuse the created component. This will help in maintaining consistency.
For example, if you are using a function named alpha, you create a corresponding
component named icon. The icon component here can be reused repeatedly
across the code. Rather than making a different component every time, reusing
the created one can save a lot of space and make the code more efficient.
It is pretty obvious that if the program is big, the component can also get fussy
and difficult to maintain. It is best to break the component down into multiple
smaller components in a scenario like this rather than making a new one.
Focus on data encryption
As per Cisco, the distributed denial of service attacks will grow by 15.4 million by
2023. The stat clearly suggests that security is the centerpiece for online apps and
websites. Therefore, if you are providing Reactjs development services, it is best
for you to focus on data encryption in your app.
People are becoming more aware of their data security and privacy. Hence, they
will not use your app, no matter how cool it looks. To ensure that your app
garners more users, keep the data in an encrypted format. Some developers
generally store user data and JWT tokens unencrypted, which can be dangerous.
The golden CSS in JS rule
Well, if you are developing an app using ReactJS, the visual elements will be
many. And as the app will scale, the number of these display elements will
increase. In general, all the CSS styles used in making the app are stored in an
SCSS file. This is done to prevent any confusion due to naming. But, when this file
becomes large, it may pose problems.
To solve this issue, CSS in Javascript can be used. ReactJS permits you to write
CSS in JS using some unique libraries such as:

4. ● Glamorous
● Styled Components
● EmotionJS
Here is how EmotionJS is used:
npm install --save @emotion/core
import { jsx } from '@emotion/core'
let Component = props => {
return (
<div
css={{
border: '1px'
}}
{...props}
/>
)
}
The choice of the library can vary based on the complexity of display elements.
For instance, if you are using a complicated theme, go for the Glamorous library.
No extra comments
One of the best things about programming languages is that they allow you to
add comments to the code. This is commonly done to make others aware of
what’s going on in the program. However, they may not be helpful all the time.

5. Too many comments in the code may make it more cluttered. If you want to
make changes to the code in the future, it may be very difficult for you if there are
comments in every line. Therefore, make it a practice to add only relevant
comments.
Keep a close check while naming the components
Naming is critical, not just in ReactJS but in every coding language. ReactJS is
primarily used for the frontend; hence, there are some rules to name its
components.
When using ReactJS, JSX is generally used, and your custom component name
may match any HTML tags. For example, the component name “menu” can
match with the HTML tag. Though React maintains a list of these tags to prevent
matching. You need to name the components with a capital first letter to prevent
this from happening.
For example, if you are naming the component, selecticon, go for SelectIcon.
Similarly, alpha should be named Alpha.
Making the first letter capital for every component is also known as the Pascal
case or upper Camel case.
DRY your code
The literal meaning here is not to repeat yourself. DRY stands for Don’t Repeat
Yourself. Therefore, if you are coding an app, you need to keep the code concise
to avoid any app issues in the future. A short and great way to do this is by
avoiding code repetition.
To ensure that your code does not have any repetition, inspect it carefully. If any
code repetition is found, go for deleting it. You need to rewrite the components’
code to cover up for the code deletion. It is necessary to support the functionality
of the deleted code.
These are some of the best practices that you can follow to ensure that your
application runs smoothly. However, they are not a routine for every developer.
So, when you take up a big app development project, hire Reactjs developers
who are well versed with these methods.
How does ReactJS promise Security?
As mentioned earlier, security is the number one priority of users these days.
Though there are many frameworks, ReactJS trumps other frameworks like
Angular by its following features!

6. 1. React provides the facility to use two-factor authentication. This ensures that
your credentials are secure even if the app crashes.
2. You can add a role-based authentication mechanism in ReactJS backed apps.
It will help you manage unauthorized access and control.
3. DDoS attacks can be dangerous for apps. You can put a bar on the request
access from an IP to prevent this. Adding app-level restrictions will also help a
lot.
4. SQL injections are primarily used for data extraction and manipulation. To
prevent these attacks, you can validate the API call functions against the API
schemas.
With so many development frameworks, it becomes difficult to choose the best
one. However, with ReactJS, you won’t have to worry about anything. It has some
great features like Virtual DOM, one-way data binding, JSX, simplicity, and
whatnot. All of these will help you craft the best.
However, having features is not it. You need to use them so that the created app
offers utility and faster performance. The tips mentioned above are some of the
best ones. As a ReactJS consultant, you need to include them in your app
development process. They will not only enhance your application’s performance
but will also garner big bucks for you.
Your ReactJS development process can experience a number of glitches which is
normal. However, if you use the tips and tricks discussed in this article, you may
forget them forever. Check them out!
