• React-DOM 18 or later

Installation

Install the package via npm:

npm install react-coderenderer

Or via yarn:

yarn add react-coderenderer

Usage

Import the CodeRenderer into your React component:

import React from "react";
import { CodeRenderer } from "react-coderenderer";
import "react-coderenderer/dist/index.css"; // Import default styles

Pass the required props to the CodeRenderer component:

<CodeRenderer code={code}>
  <MyComponent />
</CodeRenderer>

Basic Example

Here's a basic example of how to use the CodeRenderer component:

import React from "react";
import { CodeRenderer } from "react-coderenderer";
import "react-coderenderer/dist/index.css"; // Import default styles

const code = `
import React from 'react';

function MyComponent() {
  return (
    <div className="p-4 border">
        <h2 className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">My Custom Component</h2>
    </div>
  );
}

export default MyComponent;
`;

const BasicCodeRenderer: React.FC = () => {
  return (
    <CodeRenderer code={code}>
      <div className="p-4 border">
        <h2 className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
          My Custom Component
        </h2>
      </div>
    </CodeRenderer>
  );
};

export default BasicCodeRenderer;

Props

The CodeRenderer component accepts the following props:

Props

Prop	Type	Required	Description
code	string	Yes	The code to display inside the code block.
children	ReactNode	Yes	The content to display when the "Preview" button is selected.
disableDefaultStyles	boolean	No	Disables default Tailwind CSS styles if set to true.
customClassNames	object	No	Custom class names for various elements (e.g., container, button, code block).
enableDarkMode	boolean	No	Enables dark mode for the code block.

Opting Out of Default Styles

If you prefer to use your own styling or are not using Tailwind CSS in your project, you can opt-out of the default styles provided by the package. Here's how:

1. Do Not Import the Default CSS

// import "react-coderenderer/dist/index.css"; // Do not import this

2. Set disableDefaultStyles to true

Pass the disableDefaultStyles prop to the CodeRenderer:

<CodeRenderer
  code={code}
  disableDefaultStyles={true}
  customClassNames={{
    container: "my-custom-container",
    buttonGroup: "my-custom-button-group",
    button: "my-custom-button",
    copyButton: "my-custom-copy-button",
    codeBlock: "my-custom-code-block",
  }}
>
  <MyComponent />
</CodeRenderer>

3. Provide Custom Class Names (Optional)

If you want to apply your own styles, you can pass custom class names via the customClassNames prop. This allows you to fully customize the appearance of the component.

import React from "react";
import { CodeRenderer } from "react-coderenderer";
import "./my-custom-styles.css"; // Your custom styles

const exampleCode = `
import React from 'react';
const HelloWorld = () => <div>Hello, World!</div>;
`;

const MyComponent = () => <div>Hello, World!</div>;

const Example = () => (
  <CodeRenderer
    code={exampleCode}
    disableDefaultStyles={true}
    customClassNames={{
      container: "my-custom-container",
      buttonGroup: "my-custom-button-group",
      button: "my-custom-button",
      copyButton: "my-custom-copy-button",
      codeBlock: "my-custom-code-block",
    }}
  >
    <MyComponent />
  </CodeRenderer>
);

export default Example;
