# addHandler()

Deprecated. Use `addEventHandler()` instead.

## Signature

`addHandler(String eventName, Object valueProvider, Object actionExpression, Boolean insert, String phase, Boolean includeFacets)`

## Parameters

***eventName*:** Type: `String`. The name of the event to handle. For a component event, set this argument to match the name attribute of the `aura:registerEvent` tag. For an application event, set this argument to match the event descriptor, `namespace:eventName`.

***valueProvider*:** Type: `Object`. The value provider to use for resolving the `actionExpression`.

***actionExpression*:** Type: `Object`. The expression to use for resolving the handler action against the given `valueProvider`.

***insert*:** Type: `Boolean`. If `true`, put the handler at the beginning instead of the end of the handler array.

***phase*:** Type: `String`. Optional. The event bubbling phase for which to add the handler. The default value is `"bubble"`.

***includeFacets*:** Type: `Boolean`. If `true`, attempts to catch events generated by components transcluded by facets; for example `v.body`.
