Best Practices

Implementing a CDN upload/download API

When implementing a CDN upload/download API, consider the following best practices:

• Authentication & Authorization: Ensure that your API endpoints require authentication and proper authorization checks to prevent unauthorized access.

• Validate Input: Strictly validate file types and sizes to prevent uploads of potentially harmful files.

• Chunked Uploads: Implement chunked uploading for large files to enhance reliability and user experience.

• Asynchronous Processing: Consider using asynchronous processes for uploading and downloading to avoid blocking API calls, especially for large files.

• Rate Limiting: Implement rate limiting to prevent abuse and ensure service availability for all users.

• Progress Indicators: Offer real-time feedback for upload and download progress to improve user experience.

• Error Handling: Clearly communicate any errors during file operations, with descriptive messages to assist in troubleshooting.

• Data Encryption: Encrypt files at rest and in transit to protect sensitive information such as user data or intellectual property.
