Source: https://context7.com/vuestorefront/vue-storefront/llms.txt

Demonstrates how to extend existing Alokai SDK modules with custom methods, enabling additional functionality like fetching specific product types or custom endpoints. It uses `buildModule` with a custom extension function that can access base methods and the request context. The example shows how to add methods for fetching blue products and custom data, as well as combining operations.

```typescript
import { initSDK, buildModule, middlewareModule } from '@vue-storefront/sdk';
import type { SAPCCModuleType } from '@vsf-enterprise/sapcc-sdk';

// Define extension with custom methods
const customExtension = (extensionOptions, { methods, context }) => ({
  extend: {
    // Add new method that uses existing module methods
    async getBlueProducts(params) {
      const products = await methods.getProducts({
        ...params,
        color: 'blue'
      });
      return products;
    },

    // Use requestSender directly for custom endpoints
    async getCustomData(params) {
      const response = await context.requestSender('customEndpoint', [params]);
      return response;
    },

    // Combine multiple operations
    async getProductsWithReviews(productId) {
      const product = await methods.getProduct({ id: productId });
      const reviews = await context.requestSender('getReviews', [{ productId }]);
      return { ...product, reviews };
    }
  }
});

// Build module with extension
const sdkConfig = {
  sapcc: buildModule<SAPCCModuleType>(
    middlewareModule,
    {
      apiUrl: 'http://localhost:4000/sapcc',
      ssrApiUrl: 'http://localhost:8181/sapcc'
    },
    customExtension
  )
};

export const sdk = initSDK<typeof sdkConfig>(sdkConfig);

// Use extended methods
const blueProducts = await sdk.sapcc.getBlueProducts({ limit: 10 });
const productWithReviews = await sdk.sapcc.getProductsWithReviews('prod-123');
```

### Apply Alokai SDK Interceptors for Cross-Cutting Concerns

Source: https://context7.com/vuestorefront/vue-storefront/llms.txt

Illustrates how to use interceptors with the Alokai SDK to handle cross-cutting concerns such as logging, authentication, and data transformation. Interceptors can modify arguments before a request (`before`) or transform results after a request (`after`). This example shows adding an authorization header and parsing price data.

```typescript
import { initSDK, buildModule, middlewareModule } from '@vue-storefront/sdk';

// Define interceptors extension
const loggingExtension = {
  interceptors: [
    {
      // Before interceptors modify arguments
      before: {
        getProducts: async (args) => {
          console.log('getProducts called with:', args);
          // Add authentication token
          return [{
            ...args[0],
            headers: {
              ...args[0]?.headers,
              'Authorization': `Bearer ${getAuthToken()}`
            }
          }];
        }
      },

      // After interceptors modify results
      after: {
        getProducts: async (result) => {
          console.log('getProducts returned:', result);
          // Transform response data
          return {
            ...result,
            items: result.items.map(item => ({
              ...item,
              price: parseFloat(item.price)
            }))
          };
        }
      }
    }
  ]
};

// Build module with interceptors
const sdkConfig = {
  commerce: buildModule(
    middlewareModule,
    { apiUrl: 'http://localhost:4000/api' },
    loggingExtension
  )
};

export const sdk = initSDK<typeof sdkConfig>(sdkConfig);

function getAuthToken() {
  return localStorage.getItem('auth_token') || '';
}
```

### Axios Request Sender for HTTP Operations (TypeScript)

Source: https://context7.com/vuestorefront/vue-storefront/llms.txt

The AxiosRequestSender class simplifies HTTP operations by providing a fluent API for configuring requests. It includes automatic fallback from GET to POST for large payloads (414 URI too long errors) and allows custom error handlers and configurations.

```typescript
import { AxiosRequestSender } from '@vue-storefront/sdk-axios-request-sender';
import axios from 'axios';

// Create axios client
const client = axios.create({
  baseURL: 'https://api.example.com',
  timeout: 5000
});

// Use request sender in SDK method
async function getProducts(props, options) {
  try {
    const result = await new AxiosRequestSender(client)
      .setUrl('/products')
      .setMethod('GET')
      .setProps(props)
      .setConfig(options?.axiosRequestConfig)
      .send();

    return result;
  } catch (error) {
    console.error('Failed to fetch products:', error);
    throw error;
  }
}

// Custom error handling
async function searchProducts(searchTerm, filters) {
  const result = await new AxiosRequestSender(client)
    .setUrl('/search')
    .setMethod('GET')
    .setProps({ q: searchTerm, filters })
    .setErrorHandler((error) => {
      if (error?.response?.status === 404) {
        return { items: [], total: 0 };
      }
      throw error;
    })
    .send();

  return result;
}

// POST request with custom config
async function createOrder(orderData) {
  const result = await new AxiosRequestSender(client)
    .setUrl('/orders')
    .setMethod('POST')
    .setProps(orderData)
    .setConfig({
      headers: {
        'X-Api-Version': '2.0',
        'Content-Type': 'application/json'
      }
    })
    .send();

  return result;
}

// Automatic fallback for large GET requests
async function complexSearch(params) {
  // If URI too long (414), automatically retries as POST
  const result = await new AxiosRequestSender(client)
    .setUrl('/search/advanced')
    .setMethod('GET')
    .setProps(params)
    .send();

  return result;
}
```

### Implement Middleware Extensions with Request Hooks in TypeScript

Source: https://context7.com/vuestorefront/vue-storefront/llms.txt

Illustrates how to create middleware extensions using `ApiClientExtension` for Vue Storefront. It defines various lifecycle hooks (`beforeCreate`, `afterCreate`, `beforeCall`, `afterCall`) to intercept and modify API client configurations and responses, including adding authentication headers and transforming data. It also shows how to add custom API methods.

```typescript
import { ApiClientExtension } from '@vue-storefront/middleware';

// Define extension with all lifecycle hooks
const authenticationExtension: ApiClientExtension = {
  name: 'authentication-extension',
  isNamespaced: false,

  hooks: (req, res) => {
    return {
      // Modify configuration before API client creation
      beforeCreate: async ({ configuration, logger }) => {
        const token = req.cookies['auth-token'];

        logger.info('Adding authentication token to configuration');

        return {
          ...configuration,
          auth: {
            token,
            type: 'Bearer'
          }
        };
      },

      // Modify configuration after API client creation
      afterCreate: async ({ configuration, logger }) => {
        logger.info('API client created with config:', configuration);
        return configuration;
      },

      // Modify arguments before API method call
      beforeCall: async ({ configuration, callName, args, logger }) => {
        logger.info(`Calling ${callName} with args:`, args);

        // Add authentication headers to all requests
        if (args[0]) {
          args[0].headers = {
            ...args[0]?.headers,
            'Authorization': `Bearer ${configuration.auth.token}`
          };
        }

        return args;
      },

      // Modify response after API method call
      afterCall: async ({ configuration, callName, response, logger }) => {
        logger.info(`${callName} returned:`, response);

        // Transform response format
        return {
          data: response,
          timestamp: Date.now(),
          cached: false
        };
      }
    };
  },

  // Add custom methods available in integration namespace
  extendApiMethods: {
    async validateToken(context, params) {
      const { client } = context;
      const response = await client.post('/auth/validate', params);
      return response.data;
    }
  }
};

// Use extension in middleware config
export const middlewareConfig = {
  integrations: {
    commerce: {
      location: './integrations/commerce',
      configuration: {
        api: { url: 'https://api.example.com' }
      },
      extensions: (baseExtensions) => [
        ...baseExtensions,
        authenticationExtension
      ]
    }
  }
};
```

### Subscribe to SDK Events for Reactive Behavior (TypeScript)

Source: https://context7.com/vuestorefront/vue-storefront/llms.txt

This snippet demonstrates how to subscribe to SDK method lifecycle events ('before', 'after', 'error') to trigger side effects like analytics tracking or debugging. It shows defining modules with event subscribers and programmatically emitting/listening to custom events using the 'eventManager'. Dependencies include '@vue-storefront/sdk'.

```typescript
import { initSDK, buildModule, eventManager } from '@vue-front/sdk';

// Define module with event subscribers
const moduleWithEvents = (options) => ({
  connector: {
    async getProducts(params) {
      // Method implementation
      return fetch(`${options.apiUrl}/products`, {
        method: 'POST',
        body: JSON.stringify(params)
      }).then(res => res.json());
    }
  },
  subscribers: {
    // Subscribe to before event
    'MyModule_getProducts_before': (args) => {
      // Send analytics event
      window.analytics?.track('Product Search Started', {
        filters: args[0]
      });
    },

    // Subscribe to after event
    'MyModule_getProducts_after': (result) => {
      // Track successful completion
      window.analytics?.track('Product Search Completed',
        {
          count: result.items?.length
        });
    },

    // Multiple subscribers for same event
    'MyModule_getProducts_error': [
      (error) => {
        console.error('Product fetch failed:', error);
      },
      (error) => {
        window.analytics?.track('Product Search Failed',
          {
            error: error.message
          });
      }
    ]
  }
});

const sdkConfig = {
  myModule: buildModule(moduleWithEvents, { apiUrl: 'http://localhost:4000' })
};

export const sdk = initSDK<typeof sdkConfig>(sdkConfig);

// Programmatically emit and listen to events
eventManager.on('custom_event', (data) => {
  console.log('Custom event triggered:', data);
});

eventManager.emit('custom_event', { message: 'Hello from event system' });

```

### Configure Changesets for Custom Changelog Format

Source: https://github.com/vuestorefront/vue-storefront/blob/main/packages/changesets/README.md

Configures the Changesets CLI to use the custom changelog format provided by `@vue-storefront/changesets`. This involves adding the `changelog` property to the `changeset/config.json` file.

```json
{
  "changelog": "@vue-storefront/changesets"
}
```

### Fetch Physical Stores with Location Filter (JavaScript)

Source: https://github.com/vuestorefront/vue-storefront/blob/main/packages/changesets/reference-changelog.md

Illustrates the new getPhysicalStores method, which allows fetching a list of physical stores and filtering them by location. This method was added in a minor version update. The 'commerce' tag can be replaced with any eCommerce platform tag.

```javascript
// get list of physical stores in germany, "commerce" can be replaced with any eCommerce platform tag
const storesInGermany = sdk.commerce.getPhysicalStores({ location: 'germany'})
```

--------------------------------

### Update getPhysicalStores Filtering (JavaScript)

Source: https://github.com/vuestorefront/vue-storefront/blob/main/packages/changesets/reference-changelog.md

Demonstrates the change in how filters are passed to the getPhysicalStores method. Previously, filters were passed as main parameters, but now they should be passed within the 'filter' parameter. This change aims to prevent breaking changes and allow for non-filter parameters in the future.

```javascript
// Before, filters passed as main parameter
const storesInGermany = sdk.commerce.getPhysicalStores({ location: 'germany'})

// After, filters passed into `filter` parameter
const storesInGermany = sdk.commerce.getPhysicalStores({ filter: { location: 'germany'} })
```

```javascript
// Before, filters passed as main parameter
const storesInGermany = sdk.commerce.getPhysicalStores({ location: 'germany'})

// After, filters passed into `filter` parameter
const storesInGermany = sdk.commerce.getPhysicalStores({ filter: { location: 'germany'} })
```
