About

Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. By leveraging async functions, Koa allows you to ditch callbacks and greatly increase error handling. Koa does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable. A Koa application is an object containing an array of middleware functions that are composed and executed in a stack-like manner upon request. Koa is similar to many other middleware systems that you may have encountered such as Ruby's Rack, Connect, and so on - however, a key design decision was made to provide high-level "sugar" at the otherwise low-level middleware layer. This improves interoperability, and robustness, and makes writing middleware much more enjoyable.

About

Over the past two decades, Rails has taken countless companies to millions of users and billions in market valuations. Over six thousand people have contributed code to Rails, and many more have served the community through evangelism, documentation, and bug reports. Rendering HTML templates, updating databases, sending and receiving emails, maintaining live pages via WebSockets, enqueuing jobs for asynchronous work, storing uploads in the cloud, providing solid security protections for common attacks. Databases come to life with business logic encapsulated in rich objects. Modeling associations between tables, providing callbacks when saved, encrypting sensitive data seamlessly, and expressing SQL queries beautifully. Controllers expose the domain model to the web, process incoming parameters, set caching headers, and render templates, responding with either HTML or JSON.
