Data Provider Update - PUT Method Implementation

Overview

Successfully updated the BYOP dashboard to use PUT method instead of PATCH for update operations, ensuring compliance with the API specifications.

✅ Changes Made

1. Custom Data Provider (/src/dataProvider/index.ts)

• Created a custom data provider that extends the default @refinedev/simple-rest provider
• Update Method: Changed from PATCH to PUT for all update operations
• Enhanced Authentication: Consistent Bearer token authentication across all methods
• Error Handling: Improved error parsing and user-friendly error messages
• Full CRUD Support: Implemented all CRUD operations with proper headers and error handling

2. HTTP Methods Used

• GET: getOne(), getList() - Retrieve single/multiple resources
• POST: create() - Create new resources
  
• PUT: update() - Update existing resources (changed from PATCH)
• DELETE: deleteOne() - Delete resources

3. App Configuration (/src/App.tsx)

• Updated imports to use custom data provider
• Replaced dataProvider(apiUrl) with customDataProvider(apiUrl)
• Maintained all existing functionality while using PUT for updates

🔧 Technical Implementation

Data Provider Features

Authentication Handling

const getAuthHeaders = () => {
  const token = localStorage.getItem(TOKEN_KEY);
  return token ? { Authorization: `Bearer ${token}` } : {};
};

PUT Update Method

update: async ({ resource, id, variables, meta }) => {
  const response = await fetch(`${apiUrl}/${resource}/${id}`, {
    method: "PUT", // Using PUT instead of PATCH
    headers: {
      "Content-Type": "application/json",
      ...getAuthHeaders(),
      ...meta?.headers,
    },
    body: JSON.stringify(variables),
  });
  // ... error handling and response parsing
}

Enhanced Error Handling

• Attempts to parse JSON error responses
• Falls back to plain text error messages
• Extracts meaningful error messages from API responses
• Throws descriptive errors for better user experience

Consistent Header Management

• Automatic Bearer token inclusion for authenticated requests
• Support for custom headers via meta.headers
• Content-Type headers for JSON requests

🌐 API Compliance

Endpoints Affected

All component, app, deployment, and other resource update operations now use:

PUT /api/v1/{resource}/{id}

Instead of:

PATCH /api/v1/{resource}/{id}

Request Format

• Method: PUT
• Headers:
  • Content-Type: application/json
  • Authorization: Bearer {token}
• Body: Complete resource object (JSON)

Response Handling

• Supports both JSON and empty responses
• Graceful handling of different response formats
• Proper error status code handling (400, 401, 404, 500, etc.)

🎯 Benefits

API Compliance

• Matches BYOP Engine API specifications exactly
• Uses PUT for full resource replacement semantics
• Consistent with RESTful conventions

Improved Reliability

• Better error handling and user feedback
• Consistent authentication across all operations
• Robust response parsing

Developer Experience

• Clear error messages for debugging
• Extensible through meta headers
• Type-safe implementation

🔍 Testing Recommendations

1. Update Operations: Test component, app, and deployment updates
2. Authentication: Verify Bearer tokens are included correctly
3. Error Handling: Test various error scenarios (401, 404, 500)
4. Response Parsing: Test with different API response formats

📝 Usage Examples

Component Update

// This will now use PUT instead of PATCH
await update({
  resource: "components",
  id: 5,
  variables: {
    name: "updated-component",
    description: "Updated description",
    type: "microservice"
  }
});

Custom Headers

await update({
  resource: "components", 
  id: 5,
  variables: data,
  meta: {
    headers: {
      "X-Custom-Header": "value"
    }
  }
});

The implementation ensures that all update operations in the BYOP dashboard now use the PUT method as required by the API specifications, while maintaining full backward compatibility and improving error handling throughout the application.
