core.io provides a structure to quickly prototype Node.js applications by providing an eco-system of packages alongside a set of guidelines and conventions to ease development and prototyping.
In a way core.io aims to be a workflow rather than a framework by providing a common application structure regardless if your project is a web application, a desktop application, a terminal application, a microservice or data processing pipeline.
core.io provides basic building blocks which are useful in any context and help with common tasks like configuration and dependency management, logging, and basic needs of most applications.
It also provides a set of tools to ease development like the built in REPL which you can access remotely and execute commands or query data.
The heart of core.io is the application context, which loads and manages a set of core modules and which you can extend directly with custom logic or indirectly with application specific or more generic community modules.
In a sense, the application context is the kernel around which your application will grow with custom features.
Modules are intended to encapsulate code and make it portable between projects. They also serve as glue to integrate libraries like Socket.IO or AMQP into your project.
Following simple conventions on how files should be named and where those files should be placed core.io will auto-load, auto-configure, and auto-wire components while leaving to the developer the choice of overriding default behaviors. Developers can also create custom modules to replace functionality provided by core modules.
The following sections would introduce you to different topics from which you can learn more about how core.io works.

Many of the bundled modules are available to be used outside of core.io. Some of them might have up to date documentation and examples:
You can find and search for more modules in the modules page.
In order to develop core.io applications you will need to have Node.js and npm installed. You can follow instructions in the [Node.js][node] website to download and install these dependencies on your computer.
Make sure to go through the getting started guide to get a sense of what you can do with core.io.
