Importing Bootstrap into React: Step-by-Step Guide

React is a JavaScript library that lets you build user interfaces (UIs) and single-page applications. It’s loved by developers because it’s flexible and allows them to create UIs using reusable components. As a result, many developers have chosen React as the go-to front-end framework for their tech stacks.

  • However, writing Cascading Style Sheets (CSS) styles for these components can be really tough. CSS is a highly technical language and often involves tedious processes that take up a lot of development time.;
  • For instance, defining CSS styles that are scoped to global components can lead to errors, which means you have to rewrite the same CSS over and over again in different parts of the stylesheet;
  • Luckily, there are tools and libraries available, like Bootstrap CSS, that make working with CSS much easier. Bootstrap is a free and open-source CSS framework specifically designed for mobile-first front-end web development. It’s a comprehensive UI library that provides pre-defined CSS styles and other UI elements, allowing developers to quickly customize their web pages without starting from scratch.

Bootstrap can be easily combined with other front-end technologies, including React. While React helps you build the functionality of your app, Bootstrap simplifies the process of defining and maintaining the appearance of your forms.

In this tutorial, we’ll show you how to add Bootstrap to a React project and take advantage of its CSS-style capabilities.

Using Bootstrap with React

In this project, you’ll utilize React to build a simple counter component. Afterwards, you’ll incorporate Bootstrap CSS into the project to customize the front-end user interface.

To follow along with this tutorial, you’ll need:

  • Node.js installed on your computer;
  • A basic understanding of React’s functionality.

1. Set up a React application.

To create a React application, open the Node.js terminal and execute the following command:

  • npx create-react-app <name-of-your-app-here>

Replace <name-of-your-app-here> with your desired name for the React application. Now, navigate to the directory where your React application is located and locally run the app. Return to the Node.js terminal and execute the following commands:

  • cd <name-of-app>;
  • npm start.

This will launch a development server for previewing your site.

2. Add Bootstrap to the React project.

With your React application up and running, you’re prepared to integrate Bootstrap as the CSS framework. There are multiple ways to do this, but the most convenient option is to include Bootstrap as a dependency in your React application by installing the Bootstrap npm package.

First, navigate to the root directory of your React application in the Node.js terminal and run the following command:

  • npm install bootstrap.

Alternatively, if you’re using yarn, use this command instead:

  • yarn add bootstrap.

These commands will install the latest version of Bootstrap on your React app. Next, add the following line at the top of the ./src/index.js file:

  • import ‘bootstrap/dist/css/bootstrap.css’;

Note: It’s crucial to import Bootstrap at the beginning of your app’s entry file, before other CSS files. This ensures that the styles from your CSS files take precedence over Bootstrap’s styles, making it easier to customize the appearance of your application from Bootstrap’s default theme if needed.

Now, you’re ready to import Bootstrap’s classes and styles into your React application and style your components.

3. Create the counter component.

In this section, you’ll transform your empty React project into a functional counter component with a basic user interface. The finished application will display a numerical value. Below, you’ll create two buttons that increase or decrease the value by one using React’s state management hook.

To create the basic counter component, navigate to the ./src folder of your React application. The above code utilizes React’s useState hook to create the state variable “count” and sets its initial value to 0. Then, it defines the “add()” and “subtract()” functions to modify the value of “count” and assigns them as event handlers to the Add and Remove buttons.

Finally, clear the content to view your Counter component.

4. Styling with Bootstrap classes.

Your counter component is functional now, but it lacks visual appeal. That’s where Bootstrap classes come in handy, allowing you to enhance the appearance of this function.

Bootstrap provides various classes for styling your website or web-based application efficiently. These classes include:

  • Layout classes: Control the layout and positioning of elements in the viewport;
  • Component classes: Aid in styling individual components like navbars, progress bars, and buttons;
  • Utility classes: Enable you to write CSS styles for specific properties such as margins, borders, and colors.

For this project, you’ll utilize all three classes to modify the text’s size, font, and placement, as well as add style to the buttons.

Combining Bootstrap with React

In this tutorial, you’ve transformed a basic React application into something visually appealing using only a few Bootstrap classes, eliminating the need for CSS expertise.

To elevate your React application’s styling further, consider the following questions:

  • Will you be able to avoid conflicts with names and errors in specificity?
  • Can you effectively manage and organize your styles as your application expands?
  • Do you have concerns about the performance of your application? Accumulating a large number of CSS styles across multiple stylesheets can result in a larger CSS bundle size, impacting performance.

It’s crucial to prioritize a styling technique that addresses these concerns and offers a straightforward process for incorporating styles into your React applications. This approach not only saves you time and hassle in the long run but also ensures that styling your application is intuitive, efficient, and hassle-free.

Whether you’re starting a new project from scratch or integrating Bootstrap into an existing application, it can significantly reduce your development time and effort. Additionally, Bootstrap helps you create a more polished and visually appealing website that looks great on all devices.

Styles and components

Styling plays a vital role in enhancing the overall user experience of a web application. However, managing and organizing styles can become quite challenging as your React application grows in complexity. This is where incorporating Bootstrap into your project becomes incredibly valuable.

  • By integrating Bootstrap with React, you gain access to a wide range of pre-defined CSS styles and components;
  • This eliminates the need to start from scratch and allows you to quickly customize the appearance of your application;
  • Bootstrap’s extensive library offers a plethora of layout classes, component classes, and utility classes that simplify the styling process;
  • One of the major advantages of using Bootstrap is the avoidance of name collisions and specificity errors;
  • Bootstrap follows a well-structured naming convention, ensuring that class names do not clash with your custom styles;
  • This helps maintain a clean and organized codebase, preventing confusion and conflicts.

Furthermore, Bootstrap provides a standardized and consistent styling approach across different devices and browsers. Its responsive design ensures that your application looks great on various screen sizes, from desktops to mobile devices. This saves you the trouble of writing media queries and handling different device-specific styles manually.

  • Another benefit of utilizing Bootstrap is the ease of managing and tracking your styles. With Bootstrap, you can centralize your style definitions and easily locate and modify them when needed. This improves the maintainability and scalability of your project, especially when collaborating with other developers;
  • Additionally, incorporating Bootstrap can have a positive impact on your application’s performance. By leveraging Bootstrap’s optimized and minified CSS files, you can reduce the overall file size of your stylesheets. This leads to faster loading times and improved performance, particularly for users with limited bandwidth or slower internet connections.

Moreover, Bootstrap’s grid system allows for effortless creation of responsive layouts. You can easily organize and align your components using the grid classes provided by Bootstrap, saving you the hassle of manually managing complex CSS positioning.

Overall

Bootstrap’s extensive component library is another noteworthy advantage. It offers a wide range of UI elements, including navigation bars, buttons, forms, modals, and more. These pre-designed components not only save you development time but also ensure a consistent and professional look and feel across your application.

In conclusion, integrating Bootstrap with React brings numerous benefits to your styling workflow. It helps you overcome challenges related to name collisions, specificity errors, style organization, and performance optimization.
