Simple Usage (Code String)

import { CodeSamples } from '@chargebee/code-samples';
import '@chargebee/code-samples/styles';

function MyPage() {
  return (
    <CodeSamples
      codeString={`curl https://your-site.chargebee.com/api/v2/customers \\
  -u test_api_key: \\

Additional Components & Hooks

For advanced usage, you can import sub-components and hooks to build custom implementations:

Sub-Components

import { 
  CodeBlock,           // Syntax-highlighted code display
  CodeSampleHeader,    // Header with title and copy button
  Carousel,            // Multi-sample navigation
  LanguageSwitcher     // Language dropdown
} from '@chargebee/code-samples';

// Use CodeBlock for simple code display
<CodeBlock 
  code="const x = 1;" 
  language="typescript" 
  theme="github-light" 
/>

Custom Hooks

import { 
  useSampleLoader,      // Load and normalize samples
  useLanguageSelection   // Manage language state
} from '@chargebee/code-samples';

function MyCustomComponent() {
  const { samples, loading } = useSampleLoader({ /* ... */ });
  const { language, setLanguage } = useLanguageSelection();
  // ...
}

Constants

import { 
  AVAILABLE_LANGUAGES,  // List of supported languages
  DEFAULT_LANGUAGE,      // Default language ("curl")
  DEFAULT_THEME          // Default theme ("github-dark")
} from '@chargebee/code-samples';

Development

Architecture

• generators/: Language-specific code generators (Go, Node.js, Python, etc.)
• metadata/: OpenAPI metadata extraction
• components/: React UI components
• styles/: CSS themes and animations

Code Generation vs Display

Important: The CodeSamples component is a display component - it renders pre-generated code strings. It does NOT generate code from OpenAPI specs.

To generate code from OpenAPI specs, use the generateCodeSample or generateCodeSamples functions (see Pure Function API below), then pass the result to the component:

import { CodeSamples } from '@chargebee/code-samples';
import { generateCodeSamples } from '@chargebee/code-samples';

// In your loader/server component (SSG/SSR)
export async function loader() {
  const samples = await generateCodeSamples({
    languages: ['curl', 'node-v3', 'python-v3'],
    operation: 'create_a_customer',
    apiVersion: 'v2',
    pcVersion: 'v2',
    site: 'acme-test',
    apiKey: 'test_api_key',
    request: {
      uri: '/customers',
      method: 'POST',
      params: { first_name: 'John', last_name: 'Doe', email: '[e-mail]' }
    }
  });

  return { samples };
}

// In your React component
function MyPage({ samples }) {
  return <CodeSamples samples={samples} />;
}

Browser Export (Client-Side Generation)

For browser environments that need to generate code dynamically, use the browser export:

import { createCodeGenerator } from '@chargebee/code-samples/browser';

// Create a generator instance
const generator = createCodeGenerator({
  apiVersion: 'v2',
  pcVersion: 'v2',
  site: 'acme-test',
  apiKey: 'test_api_key',
  cache: 'memory' // Only 'memory' or 'none' supported
});

// Generate code for a specific operation
const result = await generator.generate({
  language: 'curl',
  operationId: 'create_a_customer',
  requestSample: {
    params: { first_name: 'John', last_name: 'Doe', email: '[e-mail]' }
  }
});

console.log(result.code); // Generated code string

Note: The browser export uses bundled operation descriptors (no external fetching required) with optional memory caching.

Pure Function API (Server-Side)

For Node.js, LLMs, Deno, Bun, or server-side generation (SSG/SSR), use the pure function API:

import { generateCodeSample, generateCodeSamples } from '@chargebee/code-samples';

// Generate code for a specific language
const result = await generateCodeSample({
  language: 'node-v3',
  operation: 'create_a_customer',
  apiVersion: 'v2',
  pcVersion: 'v2',
  site: 'acme-test',
  apiKey: 'test_api_key',
  request: {
    uri: '/customers',
    method: 'POST',
    params: { first_name: 'John', last_name: 'Doe', email: '[e-mail]' }
  }
});

console.log(result.code); // Generated Node.js code string
console.log(result.language); // 'node-v3'

// Generate code for multiple languages
const allSamples = await generateCodeSamples({
  languages: ['curl', 'node-v3', 'python-v3', 'java'],
  operation: 'create_a_customer',
  apiVersion: 'v2',
  pcVersion: 'v2',
  site: 'acme-test',
  apiKey: 'test_api_key',
  request: {
    uri: '/customers',
    method: 'POST',
    params: { first_name: 'John', email: '[e-mail]' }
  }
});

console.log(allSamples['node-v3']); // Node.js code
console.log(allSamples['python-v3']); // Python code

// Or use pre-generated samples (no generation needed)
const pregenResult = await generateCodeSample({
  language: 'python-v3',
  samples: {
    'python-v3': 'import chargebee\nchargebee.configure(...)'
  }
});

Use Cases:

• LLM/AI code generation tools
• Server-side code generation (SSG/SSR)
• CLI tools and scripts
• Non-React applications
• Testing and validation

Advanced Exports

Code Generators (Server-Side)

The code generators use pre-generated operation descriptors (bundled with the package). No external OpenAPI utils dependency is required:

import { getGenerator, getSupportedLanguages, getOperation } from '@chargebee/code-samples';

// Get list of supported languages
const languages = getSupportedLanguages(); // ['curl', 'node-v3', 'python-v3', ...]

// Get generator for a specific language
const generator = getGenerator('node-v3');

// Get operation descriptor
const operation = getOperation('v2-pcv2', 'create_a_customer');

Type Exports

  CodeSamplesPropsInterface,
