🚀 Day 333 of #365daysofcode 📚 5 Ways to Improve API Performance Efficient API performance is crucial for providing a seamless user experience and ensuring your applications run smoothly. Here are five strategies to enhance your API performance: 1. Pagination: - Improves Data Handling: Instead of loading large datasets all at once, pagination breaks down data into manageable chunks. - Reduces Load Time: By retrieving only a subset of data, you decrease the response time and reduce server load. - Enhances User Experience: Users can navigate through data more efficiently without overwhelming the server or the client. 2. Asynchronous Logging: - Non-Blocking Operations: Perform logging asynchronously to avoid blocking the main application thread. - Improves Performance: Asynchronous logging ensures that your application continues to run smoothly while logging operations are handled in the background. - Use Case: Ideal for applications that need to log extensive information without compromising performance. 3. Caching Requests: - Speeds Up Response Time: Store frequently accessed data in a cache to serve repeated requests faster. - Reduces Server Load: Decreases the number of requests to the server by reusing cached data. - Improves Scalability: Helps your application handle more requests efficiently, especially during peak times. 4. Database Pooling: - Efficient Resource Management: Use a pool of database connections to manage connections more effectively. - Reduces Latency: Minimizes the time spent establishing database connections by reusing existing ones. - Enhances Scalability: Allows your application to handle more simultaneous connections without overloading the database. 5. Payload Compression: - Reduces Data Size: Compress the data sent over the network to decrease the amount of data transferred. - Speeds Up Transmission: Smaller payloads mean faster data transfer, leading to quicker response times. - Optimizes Bandwidth: Conserves bandwidth, especially for mobile users or applications with limited network resources. Implementing these strategies can significantly boost the performance of your APIs, ensuring faster response times and a better user experience.

Hello Backend Developers → Let's level up together! Here are 5 essential backend tips to ensure clean, scalable, and efficient systems: • Consistent API Design: Use lowercase letters with hyphens for URLs (e.g., /order-history instead of /OrderHistory) to ensure uniformity. Keep endpoints RESTful and avoid verbs in URLs—use POST /users for creation, PUT /users/{id} for updates, etc. • Handle Large Datasets Efficiently: Always paginate endpoints that deal with bulk data (e.g., /orders?limit=50&offset=100) to avoid overloading the server and the client. Bonus: Implement cursor-based pagination for better performance with massive datasets. • Secure Your Endpoints: Validate inputs, sanitize data, and apply authentication and authorization rigorously. Use rate limiting to prevent abuse, especially for public APIs. • Database Schema Standards: Stick to snake_case for table fields (e.g., order_status, not orderStatus) for clarity. Always include created_at and updated_at timestamps to track the record's lifecycle. When possible, add a deleted_at field for soft deletes. • Version Your APIs: Introduce API versioning from day one (e.g., /v1/users). This ensures you can deploy breaking changes without disrupting existing consumers of your API. What other tips would you add? Share your thoughts!

Building a REST API is a fundamental task for a backend developer. If you are determined to learn how to develop REST APIs, you need to follow these concepts. 1. Proper URL path name and parameter convention - Follow RESTful conventions, and ensure the path is descriptive enough so devs/anyone can understand its purpose. Example: domain/api/v1/products 2. Proper REST method - Learn the purpose of each REST method and use them appropriately. For example, use GET for fetching data, PUT for updating, and POST for creating new entries. While there can be exceptions, it's crucial to master the basic usage of these methods. 3. Authorization / Authentication - If your API requires restricted access, ensure you include authentication and authorization checks. Additionally, understand the difference between authentication (verifying identity) and authorization (determining access permissions). 4. Validation Middleware - There are typically standard libraries/packages for API request validation. Use them! Each request should be properly validated while returning proper error messages to ensure the backend is not unnecessarily processing invalid data. 5. Controller / Service separation - Don't put all your eggs in one basket. i.e. separate your routes/controllers from your logic into separate service files. This is paramount for your code to be more modular, maintainable, reusable, and testable. Keep your controllers lean. 6. Logging - Implement application logs for key steps to help debug in production. Balance logging to avoid excessive logs but ensure enough detail to troubleshoot issues. Always log error messages and stack traces. 7. Error handling - Users don't want to see "Internal server error" or "something went wrong". Always try/catch your code wherever it can break (which is almost everywhere), and be sure to return proper error messages to inform the client accordingly. 8. Proper REST return status codes - There are specific REST response status codes for a reason. Study up on their use cases, learn the most commonly used ones, and keep the context of the API in mind while returning the response. 9. Consistent response formats - One API responds with { data: { items: [] } }, and another one responds with { items: [ ] } - this can be confusing and troublesome for frontend engineers to integrate your APIs. Use a utility function to centralize response formatting. hashtag #backenddevelopment #restapi

𝐖𝐡𝐚𝐭 𝐢𝐬: 𝐆𝐫𝐚𝐩𝐡𝐐𝐋 🤔 Most software engineers are familiar with REST and SOAP (oof...), but GraphQL remains unfamiliar to many, even though it's been around publicly since 2015. But what exactly is GraphQL, and why should you use it? In short, GraphQL is a powerful query language for APIs that allows clients to request exactly the data they need. Nothing more, nothing less. While with REST you retrieve a fixed structure of data and might need multiple calls to get exactly what you need, with GraphQL you have one endpoint, one call and one response, to get exactly what you need. Only the relevant pieces of information. 𝐖𝐡𝐲 𝐬𝐡𝐨𝐮𝐥𝐝 𝐲𝐨𝐮 𝐮𝐬𝐞 𝐢𝐭? 👉 𝐄𝐟𝐟𝐢𝐜𝐢𝐞𝐧𝐭 𝐝𝐚𝐭𝐚 𝐟𝐞𝐭𝐜𝐡𝐢𝐧𝐠 Get exactly what you need. There's no over-fetching or under-fetching. 👉 𝐒𝐢𝐧𝐠𝐥𝐞 𝐞𝐧𝐝𝐩𝐨𝐢𝐧𝐭 Only one endpoint is needed to get all your data. This also means less network calls between the client and server. 👉 𝐍𝐨 𝐦𝐨𝐫𝐞 𝐛𝐚𝐜𝐤-𝐚𝐧𝐝-𝐟𝐨𝐫𝐭𝐡 𝐛𝐞𝐭𝐰𝐞𝐞𝐧 𝐟𝐫𝐨𝐧𝐭-𝐞𝐧𝐝 𝐚𝐧𝐝 𝐛𝐚𝐜𝐤-𝐞𝐧𝐝 𝐝𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫𝐬 With GraphQL, front-end developers can easily tweak their queries to get the exact data they need - no need to ask the back-end developers for custom endpoints. 👉 𝐑𝐞𝐚𝐥-𝐭𝐢𝐦𝐞 𝐝𝐚𝐭𝐚 GraphQL supports subscriptions natively, enabling real-time updates. I'm currently learning to use GraphQL with .NET and so far it is a very interesting tool. Have you used GraphQL before?
