Components

This page is our old "registry". If you want to add your component to our new registry crawler, available via component-search(1) and http://component.github.io please visit our crawler app and type in your username at the bottom or use the CLI: component crawl <user>

The eventual goal of components is that you use only the pieces that you need, not large libraries like jQuery or underscore, these should be application-level dependencies, if used at all. However if you must use them for now, design your APIs in such a way that these are merely implementation details, for example $(selector).mylibrary(options) is not a good choice, so that they can be phased out. Try your best to create components everyone may use, then create backbone-<name> based on that code when possible, otherwise the community will remain fragmented.

If you would like to help maintain any component/* components, please ping @jongleberry!
