Router.cr: The Minimal Yet Powerful HTTP Router for Crystal

Router.cr is a minimalist HTTP router that is tailored for the Crystal language. It stands as a lightweight, yet powerful, library that is designed to undefine the complexities of building applications or APIs using the Crystal Language. Its relevance comes from the need for a simple and visible implementation of routing - a key aspect in the development of web applications.

Project Overview:

Router.cr aims to provide developers who use the Crystal language with an easy-to-use yet powerful HTTP router. This package addresses the need for effective routing functionality, something that is integral while creating APIs or building web-based applications. Crystal developers who want to simplify their development processes without compromising on performance are the primary users of Router.cr.

Project Features:

Some key features of Router.cr include defining routes with variables, query parameter support handling, HTTP methods restrictions and the ability to organize routes with scopes. These features help to simplify handling HTTP requests and organizing routes which is a crucial element in developing applications in Crystal. For example, defining a route with a variable allows you to have a dynamic URL, so each time the URL is accessed differently, the router is capable of managing it without each potential route having to be hard-coded.

Technology Stack:

Router.cr is implemented in Crystal language. Crystal was chosen due to its similarity to Ruby, both in terms of readability and simplicity, but with the performance advantages of compiled languages like C. Moreover, Crystal offers efficient type checks during compile time and lesser memory containment errors at runtime which makes it a suitable choice for router.cr project.

Project Structure and Architecture:

Router.cr follows an organized modular structure that makes understanding the project easier. A route’s only argument is a block (or a Proc) and this allows the coder to make direct requests such as 'get', 'post', or 'put'. Path parameters and query parameters are handled in a quite straightforward way, enhancing the clarity in routing procedure.
