# Create a Build for Your React.js App

In this blog post, I'll show you how to make a build for your React.js app. But first, you might be wondering: Why bother with a build?

Let's talk about why it's important to create a build for your React.js application.

So, you've finished making your website with React.js, and now it's time to get it online. To do that, you'll need to host the build folder.

Here's a simple step to create build folder: Open your React.js project and just type this command:

```bash
npm run build
```

This command does something cool – it makes a new build folder right there in your project. Inside, you'll find all the static files and content ready to roll.

Now, let's test it out:

```bash
npm i -g serve  # Install the 'serve' package globally
npx serve build  # Run the project locally
```

This will let you check how your project looks and behaves in action.
