Component Namespace

Every component is part of a namespace, which is used to group related components together.

Another component or application can reference a component by adding <myNamespace:myComponent> in its markup. For example, the helloWorld component is in the auradocs namespace. Another component can reference it by adding <auradocs:helloWorld /> in its markup.

You must register a namespace to use the Lightning Component framework in your organization. See Before You Begin.
