Build a Complete Typescript React Fitness Application for Beginners | Responsive

Fitness has become an essential part of our lives, and creating a fitness application can be a great way to help people achieve their health and fitness goals. In this article, we will learn how to build a complete TypeScript React fitness application for beginners, making it responsive and easy to use for users on different devices.

Setting up the Project

The first step is to set up our project. We will need Node.js and npm installed on our system. Once we have that, we can create a new React application using create-react-app.


npx create-react-app fitness-app --template typescript


This will create a new TypeScript React application in a directory called “fitness-app”.

Creating the Foundation

Now that we have our project set up, let’s start by creating the foundation for our fitness application. We will create a few components such as a header, footer, and a main content area.

We can create a new folder called “components” in the src directory and create our components inside it.

Header Component

Create a new file called “Header.tsx” and add the following code:


<header>
<h1>Fitness App</h1>
</header>


Footer Component

Create a new file called “Footer.tsx” and add the following code:


<footer>
<p>© 2021 Fitness App. All rights reserved.</p>
</footer>


Main Content Component

Create a new file called “MainContent.tsx” and add the following code:


<main>
<h2>Welcome to Fitness App</h2>
<p>Start your fitness journey today.</p>
</main>


Creating the Layout

Now that we have our components ready, let’s create the layout for our fitness application. We will use a flexbox layout to arrange our components.

Create a new file called “App.tsx” in the src directory and add the following code:


<div>
<Header />
<MainContent />
<Footer />
</div>


Making it Responsive

To make our fitness application responsive, we can use CSS media queries to apply different styles based on the device screen size. We can create a new file called “App.css” in the src directory and add the following code:


@media screen and (max-width: 768px) {
body {
background-color: lightblue;
}
}


Running the Application

Finally, we can run our fitness application using the following command:


npm start


This will start the development server, and our fitness application will be accessible at http://localhost:3000 in your browser.

In this article, we have learned how to build a complete TypeScript React fitness application for beginners. We started by setting up our project, creating the foundation components, and then creating the layout. We also made our application responsive using CSS media queries.
