Markdown is becoming increasingly popular due to its simplicity and ease of use while writing content. React is a native JavaScript library that allows you to create user interfaces. By combining these two technologies, we can develop a Markdown editor that enables users to compose and preview Markdown material in real time. Markdown is one of the most effective methods of formatting information, and it is extensively used on blogging sites to boost visual appeal. In this article, we'll learn how to create a Markdown editor with React. ## Prerequisites Before we begin: - Have a basic understanding of [React](https://react.dev/) - Ensure [Node.js](https://nodejs.org/en) is configured on your system. - A text editor: preferably [VScode](https://code.visualstudio.com/) (I prefer Visual Studio code because of its simplicity) ## What is Markdown? Markdown is a straightforward text format. It presents HTML (Hypertext Markup Language) as a simple, fundamental, and easy-to-write alternative. Users can structure and arrange their content using Markdown. You can use several formatting syntaxes with markdowns, such as headers, emphasis (bold and italic), lists, links, photos, and more in a markdown. ## Why use Markdown? - Markdown simplifies text formatting without complex HTML tags. - Markdown prioritizes readability and separates content from presentation. - Markdown files can be reused across different components or pages. - Numerous libraries and tools support Markdown rendering. - Markdown enhances text formatting, readability, and reusability. ## 1. Setting Up the Project First, let's create a new React project using the `Create React app `or the` Vite tool`. I recommend using the [Vite tool ](https://vitejs.dev/)to create a React boilerplate, although `create react app` is also a good option. The reason for my preference is that `Vite` is not only faster for development but also easier to configure. Additionally, Vite is more versatile than the `create react app.` - Open your terminal and run the following command: ``` npx create-react-app . or npx create-vite@latest . ``` I'm using the period because I'm inside the folder. Using the period (.) is just a shortcut when you're sure you're in the folder. But if you haven't done so, once you've created the project, make sure to navigate into the project directory. ``` cd markdown-editor ``` - Installing Dependencies Next, we need to install a Markdown parser and a React Markdown component. We'll use `marked`, a fast markdown parser, and `react-markdown`, a React component, to render Markdown as React components. Install these dependencies by running: ``` npm install marked react-markdown ``` **Source:**[ react-markdown](https://www.npmjs.com/package/react-markdown) ## 2. Creating the Markdown Editor Component Now, let's create a new file named `MarkdownEditor.js` inside the `src` directory. This component will consist of a textarea for inputting Markdown content and a preview section to display the rendered HTML. ``` import React, { useState } from 'react'; import ReactMarkdown from 'react-markdown'; const MarkdownEditor = () => { const [markdown, setMarkdown] = useState(''); const handleChange = (event) => { setMarkdown(event.target.value); }; return (

<div>
        <h2>Preview</h2>
        <ReactMarkdown>{markdown}</ReactMarkdown>
      </div>
    </div>
  );
};

export default MarkdownEditor;
```

In the code above the **useState()** hook takes the value of the user. It is simply used to store the variable and set an update whenever there is a change and the onChange event is used when there is an update or change.

**3. Integrating the Markdown Editor Component**

Now, let's integrate the `MarkdownEditor` component into our `App` component. Open `src/App.js` and replace its contents with the following code:

App.jsx
```

import React from 'react';
import MarkdownEditor from './MarkdownEditor';

function App() {
  return (
    <div className="App">
      <h1>Markdown Editor</h1>
      <MarkdownEditor />
    </div>
  );
}

export default App;
```

## 4. Running the Application

Once you've saved your code, run our React application, and go back to your browser. You should see something similar to the result below. 
```
For Vite, use npm run dev.
For Create React App, run npm start
```
This command will start the development server, and you should see your Markdown editor running in your default web browser at `http://localhost:5173` or `http://localhost:3000`.

## Conclusion

In conclusion, making a Markdown editor using React is a simple yet effective way to create content. While React works well for many projects, it's important to think about what each project needs and consider other options if necessary. But don't worry, React is popular and keeps getting better, so it's a smart choice for web development.

If you're new to React, don't be afraid to learn and try new things. Knowing React is a valuable skill that can open doors to job opportunities. And by working on projects like those in Co.Lab, you'll see how React can solve real problems.

Now that you've learned how to make a Markdown editor, you can try making other cool things too! Maybe a to-do list app, a weather forecast for your area, or a simple game like tic-tac-toe. Just keep practising and trying new ideas. That's how you'll get good at React.

Keep coding, keep learning, and keep challenging yourself. You'll be amazed at what you can do with React!
