Quick Summary: – In the last couple of years, our web development team has built enterprise-grade React apps of all complexities. We have a team of world-class React experts’ part of our in-house team, who are always keen to acquire more valuable insights and knowledge.

In this article, our React experts will talk about the key tips and practices about React architecture that will enable you to code better and build a performance-driven, scalable and secure React app easily.

Let’s begin!

We all know that ReactJS is one of the best web development frameworks to work with. Whether you want to build a small application or a complex one, a scalable architecture like that of React can help serve that purpose easily. Especially when you want your web app to serve a large number of users.

That’s is why understanding the technical aspect of any architecture, in this case, React architecture to build large-scale websites can enable you to make better, smarter business decisions.
Let’s jump in and see everything important regarding React architecture there is to know:

1. What exactly is React architecture?

Reactjs doesn’t have a rigid architecture pattern, unlike what other UI libraries and web frameworks have.

It is just a view that allocates to the needs of the user interface.

Beneath the UI, there are many React components; a small structural unit- like a label, button, input text label or something as complex as a registration form, etc.

But that’s not even the greatest thing about React: all React components can hold a state; but, it’s not necessary. By state, we mean the necessary data that is needed for the app to work.

So whatever action the user takes, will correspond to the necessary change in the state from time to time.

That means whatever is the current state of the data, will determine the elements displayed on the UI of the app. This is simply how the React architecture functions.

React js architecture is one of the best out of the lot to build large scale web applications. Here’s why:

It has a consistent global state – This global state allows all app data to be stored in it. Any change to this state will automatically update all the corresponding views.

Better scalability – When integrated with a scalable backend like Nodejs, the React js architecture can easily handle increased workloads and meet business needs more efficiently.

Better testing – All the React components and features are independent, therefore, it is easier for developers to carry out a test quickly for the particular part of the application they need to check.

Decoupled components –Redux-saga is used by React to tie decoupled components together. This helps support asynchronous flow for better testing.

4. React Architecture Best Practices- As Per Industry Experts

We can’t stress this fact enough; it is integral to follow the best practices of React architecture to build a large application that stands the test of time.

From using the high-quality coding standards to organizing the folder structure for different teams, if you ask us, best practices can never see the end of the light.

Some developers would like to give names they can remember to their files, while for others, it could be using the best ReactJS libraries to enhance and increase the efficiency of the app.

Here are the best practices to follow using React architecture:

1. Avoid using a lot of nested files & folders

For some developers, giving meaningful names to your files could be the best practice, whereas, for others, it could be as simple as using the best libraries that optimize the workflow.
We reached out to several Reactjs experts and contributors to find out the practices they follow to scale large web applications. Here’s what they shared with us:

2. Reuse your components

The golden rule in React is to create one component for each function so that you can use it over and over again. This means that if you need to build a new component for a function that is the same as before, use that instead of creating the new one.
If the size of the component becomes large, it’s better to break them up into smaller components.
Reusing React components in your project or across multiple projects you develop will help you achieve better reliability.

3. Put CSS in JavaScript

When you start with your React project, industry experts say that it’s best to keep all your CSS styles you are going to implement in one SCSS file.

Some libraries like EmotionsJS & Glamorous will allow you to write CSS in JavaScript.

If you’re thinking that some CSS names might collide, using global prefixes can help avoid that. But if your project size increases, this might not be a practical approach.

4. Comment only where necessary

You should always add comments to your code, but only where you think it is an absolute must. This is one of the best React practices you should follow.
It will help:

– Keep the codes easier to read.
– If you are going to edit the code, later on, it can help avoid a conflict between the comment and code.

5. Use capitals for Component Names

The majority of React developers use JSX (a JavaScript extension). If you are also planning to use that then you should make sure that the names of the components you create need to begin with uppercase letters.

For instance, you’ll name components as “SelectButton”, and not “ selectbutton”.By carrying this out, the JSX will automatically identify them uniquely from the default HTML tags.

The early React versions used to have a list of all built-in names to differentiate them from custom names. Since the list needed to be updated regularly, capital letters became the new standard.

However, this is specifically if you go with JSX. If you use any other language you can use lowercase letters. But keep in mind that it might help reduce the reusability of components beyond the scope of your project.

6. Use React’s Bit tool

The Bit tool is one of the best React tools that will help you better organize React components in your project easily.

This tool also helps to increase the reusability of code, along with promoting teams to collaborate to build components.

7. Use snippet libraries

React architecture best practices also involve using code snippets.

When you use code snippets, it will make it easy for you as a developer to keep up with the latest syntax. You’ll also be able to keep the code relatively bug free, which is why as a developer, this is one of the React bet practices to follow.

Some snippet React libraries you can use are:

– ES7 React
– Redux
– JS Snippets

The Takeaway

Technological innovations have become fast-paced in this era.

The expectations of your customers will always be more. So when it comes to creating a new website or an app for your business or even releasing a new enhanced feature for your app, being at par with the demands of your users becomes crucial to success.

That’s why it’s necessary to build your digital product with a scalable architecture pattern.

And React architecture is one of those scalable frameworks for web development. In this piece, we went over React JS architecture’s best practices to build remarkable and highly-performing React web apps.

We hope it helped you gain valuable insights and understand React architecture better.
