Micro Frameworks
Micro frameworks are lightweight web application frameworks that provide minimalistic, core functionality for building web services and APIs, typically focusing on routing, HTTP request/response handling, and middleware support without built-in components like ORMs or templating engines. They are designed for simplicity, flexibility, and low overhead, allowing developers to add only the features they need through plugins or extensions. Examples include Flask for Python, Express.js for Node.js, and Sinatra for Ruby.
Developers should use micro frameworks when building small to medium-sized web applications, RESTful APIs, or microservices where performance, minimalism, and rapid development are priorities, as they reduce boilerplate code and offer fine-grained control over dependencies. They are ideal for prototyping, single-page applications, or projects requiring integration with specific libraries, as they avoid the bloat of full-stack frameworks and enable faster deployment with less resource consumption.
