Building Modern APIs: REST, GraphQL, and gRPC Choosing an API style depends on what you build. REST, GraphQL, and gRPC each fit different goals. Understanding their strengths helps you design interfaces that last. The right mix can speed development and improve the experience for developers and users alike. REST treats data as resources. Use clear nouns in the URL, such as /users or /orders. Use HTTP methods to act on resources: GET, POST, PUT, DELETE. REST calls are stateless, cache-friendly, and easy to test in the browser. For public APIs, REST often remains the simplest path. ...

APIs and Middleware: Building Connected Systems APIs connect apps, services, and teams. Middleware sits between them, translating formats, handling retries, and enforcing policies. When designed well, you get reliable communication, better security, and easier maintenance. What are APIs? They are contracts that let one system request data or actions from another. What is middleware? It is the software layer that sits in the middle: API gateways, message queues, service meshes, and integration services that route, transform, or protect messages. ...

Building Secure Web Services: From Design to Deployment Security should be part of every step, not an afterthought. It starts with a clear view of what you protect, who can access it, and how you respond when things go wrong. From API design to deployment, small choices add up to a safer service. In practice, you can combine simple, proven ideas into a strong foundation. Designing for security from the start Build with least privilege for all parts, defend with multiple layers, and keep defaults strict. Validate inputs at every edge, fail safely, and use secure defaults that minimize exposure. ...

The Shape of APIs: REST, GraphQL, and gRPC Uncovered APIs are the quiet plumbing of modern software. They let apps, services, and devices talk to each other. REST, GraphQL, and gRPC offer different ways to shape that conversation. Understanding their core ideas helps teams pick the right tool for the job. REST helps you work with resources using standard HTTP. Each endpoint represents a resource and uses methods like GET, POST, PUT, and DELETE. Because HTTP is widely understood, REST endpoints are easy to explore with simple tools, and they often benefit from built‑in caching and clear status codes. A typical REST call might fetch a user with GET /users/42 and return JSON like { “id”: 42, “name”: “Alex” }. REST shines when you want predictable URLs and broad client support. ...

APIs and Middleware: Building Bridges Between Systems APIs and middleware act as bridges between systems. They help teams move data, automate workflows, and add features without rewriting every app. An API defines a contract: what you can ask for, and what you will receive. Middleware sits between services to handle tasks that cut across programs, such as security, data transformation, and reliable messaging. Together, they keep systems flexible and easier to maintain. ...

Building Secure APIs and Services APIs connect apps and services. A secure API reduces risk, protects user data, and builds trust across teams and customers. Good security should be baked in from the start, not added after a breach. Begin with threat modeling. Map data flows, identify who uses the API, and where data travels. List threats like broken access control, injection, and misconfiguration. The goal is clear protection and measurable risk. ...
