How to write SAAS in ReactJs

Hi Guys, In this article, you will discover how to leverage SAAS in a ReactJS Application. We will use the node-sass module to work with SASS in React js environment.

Introduction to Saas

The sophisticated module Node-sass provides binding for Node.js to LibSass, the current version of the well-known Sass stylesheet preprocessor. Through a connect middleware, it enables your react to generate .SCSS files to CSS at an astoundingly quick rate natively.

SASS provides practical and simple ways to style contemporary web applications. SASS opens the door to simplicity and enables us to create CSS code that is easier to maintain and more modular.

It may be a little troubling at first if you are new to React and having trouble adding SASS to React, but if you follow the instructions, you should have no trouble configuring SASS in React.

How to use SAAS in a React Application

For this example, I will be showing you how to add SAAS to a new React application as well as adding SAAS to an already existing React application.

Adding SAAS/SCSS using Node SASS Module to a new React application

To add SAAS to a new React application follow the steps as illustrated below;

Create React App
Install Node SASS Package
Write SASS in CSS File
Create Component File
Update App Js File
View App in Browser

Create React App

You must install the develop react app tool on your computer before you can begin using React.
```
 npm install create-react-app --global
```
Run the following command from the terminal to install a new React app:
```
 npx create-react-app react-demo
```

Next, change into the project folder.

cd react-demo

Install Node SASS Package

To integrate SASS in React, you require to add the node-sass module in React application using the node package manager.

npm install node-sass

Write SASS in CSS File

Search the src folder for the App.css and index.css files, then change both of their extensions from.css to .scss

The styling code provided must be added to the App.scss file:

body{
  background-color: yellow;

  .scssStyling{
    padding: 20px;
    h1{
      background: white;
      text-align: center;
      padding: 10px;
      font-size: 18px;
    }
    p{
      text-align: center;
      font-style: italic;
    }
}
}

Create Component File

In this step, we'll create the components directory in the source folder and a file called Example.js inside of it.

We need to add the scssStyling class to the div so that the React component can have SASS styling.

import React from 'react'

const Example = () => {
  return (
    <div className='scssStyling'>
        <h1>
            Congratulations You are now using SASS in React😁😁
        </h1>
        <p>
            Now you can do more!!!!
        </p>

    </div>
  )
}

export default Example

Update the App.Js File

In order to see the changes of SASS in React component we have to register the React component inside the main React component.

Place the provided code into the open App.js file.

import React from 'react';
import './App.scss';
import Example from './Example';

function App() {
  return (
    <div className="App">
      <Example />
    </div>
  );
}

export default App;

View App in Browser

Open the console in the final step, enter the command, and then click OK:

npm start

After running the command, react server is running, open the given url on the browser to test the app:

http://localhost:3000

and Voilaaa!!!!!.

Adding SAAS/SCSS to an existing react application.

To achieve this you don't have to start by creating a new React application, all you need to do is to :

Install Node SASS Package
```
  npm install node-sass
```
Create a .scss file for the component you will like to add the styling to
Export and render the particular component so that you can see the changes, and that will be all.

Conclusion

This short lesson showed us how to configure Sass in a ReactJS application.

We utilized the Node Sass module to implement SCSS or SASS in React.

I hope this will aid you in your endeavors as a developer and broaden your understanding of React programming.
