Welcome to a journey where we’ll develop a simple yet effective Body Mass Index (BMI) calculator using React Hooks. This project will enable users to calculate their BMI and store their results for up to seven days using LocalStorage. Let’s dive into the details!

Getting Started

Before we set sail on the seas of code, let’s make sure you have the right tools at your disposal.

• Node.js installed on your machine.
• npm (Node Package Manager) to manage packages.
• A code editor of your choice (e.g., VS Code).

Installation

To kick off your BMI calculator project, we need to install the necessary packages. Open your terminal and run the following command:

npm install

Usage

Once the packages are installed, you’re all set to run the application. Use the command below:

npm start

Understanding the Code: The Analogy

Think of building our BMI Calculator like constructing a house. Each major component of your app represents a different room, each with its own purpose:

• Foundation (useState and useEffect): The base of your house that keeps everything steady. useState helps manage the state of your application, while useEffect allows you to perform side effects, such as fetching data or interacting with LocalStorage.
• Walls (JSX Layout): The framework that holds everything together, just like how walls provide structure to your home. JSX serves as the visual guide for your users and organizes components.
• Doors (Event Handlers): The points of entry for interaction, much like doors that allow people in and out of your home. Event handlers listen for user inputs and trigger responses in your app.

Enhancements

Once the fundamental structure is in place, consider making the following enhancements for a more polished application:

• Remove the dependency of Materialize-CSS module to achieve a cleaner design.
• Fix any issues with chart behaviors when hovering over old points to improve user experience.

Troubleshooting

If you encounter issues while setting up your BMI calculator, here are a few troubleshooting tips:

• Installation Errors: Ensure you are in the project directory and have all prerequisites installed.
• Running Issues: If the app doesn’t start, verify your package.json for any inconsistencies and rerun npm install to fix any missing dependencies.
• LocalStorage Issues: Ensure that your browser allows LocalStorage and does not have private browsing enabled, which may restrict data storage.
