Node Error ========== _Node.js project_ #### Exposes the errno codes #### [Show me!](#showme) | [Availability](#availability) | [Compatibility](#compatibility) | [Documentation](#documentation) Version: 1.0.2 When you are writing a node.js module you"ll probably deal with errors. If you get a predefined error you can just throw it via a callback but if you want to instantiate a predefined one you need an errno code. Node.js does not expose these errors. Furthermore, they"re not the standard errno codes. They are defined at [`deps/uv/include/uv.h`](https://github.com/joyent/node/blob/master/deps/uv/include/uv.h). This module eases the error management providing predefined `Error` instances for every errno code and the ability to create customized errors. #### Show me!
