React is a widely used library for building modern web applications. It provides powerful features for managing complex states and creating dynamic user interfaces. However, designing visually appealing interfaces can be challenging, especially for developers with limited design experience. This is where Bootstrap comes in handy. Bootstrap is a popular front-end framework that offers a wide range of pre-designed components for creating attractive and responsive web interfaces. By combining React with Bootstrap, developers can create interfaces that are both functional and visually appealing. In this blog, we will explore the best practices for using Bootstrap with React.
Before we dive in, it would be good to know how React works.

Why use React with Bootstrap?
React and Bootstrap are two of the most popular JavaScript and CSS frameworks, and they complement each other well for creating dynamic user interfaces and web applications. Both frameworks offer a variety of features and functionalities that streamline the development process, including reusable components, state management, and routing. Bootstrap provides pre-built CSS styles and components that can be easily integrated into your project. These pre-built UI components include navigation bars, forms, buttons, and more. By combining Bootstrap with React, developers can quickly and easily create dynamic and responsive user interfaces. This allows you to focus on the functionality of the website without worrying about its appearance.
Pre-requisites Node.js is required to set up a React web application on your system. You can check whether Node.js is installed on your machine by running the following command:
Setting up React Project
The initial step is to create a React project which can be done by using create-react-app (CRA). You can create a basic React app by suitably running the following command:
To go to the React directory:
Then, you can run the command to initiate the project:
How to use Bootstrap in React:
Install Bootstrap to React using Bootstrap CDN
The Bootstrap CDN is a free service that lets developers use the latest version of Bootstrap without needing to download or install it. All you need to do is include the Bootstrap CDN link in the head section of your HTML file, and you're set.
To get started, add the following link to the head section of your public/index.html file:
This link fetches the latest version of Bootstrap from the CDN and applies the default styles to your application.
If your application requires JavaScript components, such as dropdowns or modals, you will need to include the following JavaScript libraries at the bottom of the body section, just before the closing </body> tag:
These scripts will undoubtedly provide the necessary JavaScript components to your application, allowing you to utilize them in your code.
You can quickly add Bootstrap to your React application by using the "Bootstrap CDN" without having to download or install anything. This method saves you time and effort, allowing you to concentrate on the developing the functionality and user experience of your application.
Importing Bootstrap in React as a dependency
If we want to import Bootstrap, in React, as dependency then, using a build tool or module bundler such as Webpack is often preferred.
To get started with, one can use the command 'npm install bootstrap' to install the most recent version of Bootstrap in your application. You can then include it in your app's entry file, such as the 'src/index.js' file in a project built with create-react-app, by importing the Bootstrap CSS and associated JavaScript files.
Or if you are using Yarn:
Once Bootstrap’s been enabled, make sure to include this in your app's entry file, such as 'src/index.js':
It's important to note, that the order of these imports is importance. The CSS file should be imported, before any custom CSS, and the JS file should be imported after jQuery and Popper.js (which are dependencies of Bootstrap). Here's an example of how to import all three dependencies in the correct order:
After completing this process, you'll be able to use Bootstrap's pre-built CSS classes and JavaScript components in your React app components.
Install React Bootstrap package (bootstrap-react and reactstrap)
When incorporating Bootstrap, into a React application, it's common to use the React Bootstrap kit. This kit includes various Bootstrap packages that have been reconstructed, as React components. The two most popular packages are:
- react-bootstrap: This package is almost a complete rewrite of Bootstrap components using React. It provides a set of components that can be used in React applications, to achieve the same look and feel as Bootstrap.
- reactstrap: This package is a library of React Bootstrap 4 components, that emphasizes composition and independence from jQuery or the Bootstrap JavaScript library. It provides a set of reusable components, that can be composed together to build complex UIs in React applications.
Both of these packages are great options for incorporating Bootstrap, into React applications, and the choice between them depends on the specific needs of the project.
React-bootstrap
To install Bootstrap in a React project, using npm, execute the following command, in the Bash terminal:
After the installation is complete, one can import the Bootstrap CSS file in the src/index.js file using the following code snippet:
Make sure to add this line at the top of the index.js file, above all other imports.
Then, in the index.js file, you can use the imported Bootstrap components in your React application. Here's an example:
In this example, the bootstrap.min.css file is imported at the top of the index.js file. The App component is then rendered in the rootDOM element, and the registerServiceWorker method is called.
Reactstrap
To install the Reactstrap library, in your React project using npm, run the following command, in your Bash terminal:
Once installed, you can import Reactstrap components into your React application. These components are pretty similar to other React components and can be used in the same way. Here's an example of how to import multiple Reactstrap components:
Using Bootstrap in React Applications
While Bootstrap is excellent for quickly building visually appealing and responsive apps, it's crucial to consider its impact on your application's performance. Bootstrap includes a variety of styles and scripts, which can significantly increase your application's load time and memory usage.
One way to optimize the performance of your Bootstrap-based React application is by using lazy loading. Lazy loading defers the loading of non-critical resources, such as images, scripts, and styles, until they are actually needed. This can help reduce the initial load time of your application and enhance the user experience.
Another technique to optimize performance is code splitting. Code splitting breaks your application's codebase into smaller, more manageable chunks, which can then be loaded on demand. This can reduce the amount of JavaScript and CSS that needs to be loaded upfront and improve the overall performance of your application.
Caching is also a highly effective way to boost performance. By caching frequently accessed resources, such as images and scripts, you can reduce the number of requests made to the server and speed up the rendering of your application. Various caching strategies include browser caching, CDN caching, and server-side caching.
It's also important to avoid unnecessary styles and scripts. While Bootstrap offers a rich set of UI components, you may not need all of them in your application. By selectively importing only the components you actually need, you can reduce the size of your application's CSS and JavaScript files and enhance its performance.
To sum up, when using Bootstrap in React, it's vital to consider its impact on performance and take steps to optimize it. By using techniques such as lazy loading, code splitting, caching, and selective imports, you can improve the performance of your Bootstrap-based React application and provide a better user experience.
Next, let’s discuss some best practices to follow when using Bootstrap in your React project.
Best practices for using Bootstrap in React
- Use the Bootstrap CSS, and, JavaScript files via a CDN or by installing them via npm.
- Use React-Bootstrap, or another third-party library, that provides React components, for Bootstrap, instead of using jQuery-based Bootstrap components.
- Customize Bootstrap styles, by creating a custom CSS file, and overriding the default Bootstrap styles.
- Use a grid system to create responsive layouts that respond to different screen sizes.
- Use the built-in form components to construct forms that are compatible with the overall look of your application.
- Avoid overusing pre-designed components, as this can result in a generic-looking interface that lacks individuality.
- Use Bootstrap's utility classes to add additional styles to elements without the need for original CSS.
- Use a theme, or design system, based on Bootstrap to ensure a more consistent appearance and feel across your application.
- Improve efficiency by only loading the necessary Bootstrap components and limiting the amount of custom CSS. - Test your interface on various screen sizes and devices to ensure it is responsive and looks good on all of them.
- Ensure that your styling approach avoids name collisions and specificity errors. This allows you to manage styles as your application grows, and does not negatively impact your application's performance.
It’s of paramount importance to choose a styling technique that addresses the core of these concerns and makes the process of adding styling to your React application easy and efficient. Following these best practices that will help you create beautiful, responsive, and performant interfaces with Bootstrap and React.
