Transition Class

A Transition is a thennable (a promise-like object) that represents an attempt to transition to another route. It can be aborted, either explicitly via abort or by attempting another transition while a previous one is still underway. An aborted transition can also be retry()d later.

Constructor

Transition

(
  • router
  • intent
  • state
  • error
)
private

Parameters:

  • router Object
  • intent Object
  • state Object
  • error Object

Methods

abort

() Transition public

Aborts the Transition. Note you can also implicitly abort a transition by initiating another transition while a previous one is underway.

Returns:

Transition:

this transition

catch

(
  • onRejection
  • label
)
Promise public

Forwards to the internal promise property which you can use in situations where you want to pass around a thennable, but not the Transition itself.

Parameters:

  • onRejection Function
  • label String

    optional string for labeling the promise. Useful for tooling.

Returns:

Promise:

finally

(
  • callback
  • label
)
Promise public

Forwards to the internal promise property which you can use in situations where you want to pass around a thennable, but not the Transition itself.

Parameters:

  • callback Function
  • label String

    optional string for labeling the promise. Useful for tooling.

Returns:

Promise:

followRedirects

() Promise public

Transitions are aborted and their promises rejected when redirects occur; this method returns a promise that will follow any redirects that occur and fulfill with the value fulfilled by any redirecting transitions that occur.

Returns:

Promise:

a promise that fulfills with the same value that the final redirecting transition fulfills with

method

(
  • method
)
Transition public

Sets the URL-changing method to be employed at the end of a successful transition. By default, a new Transition will just use updateURL, but passing 'replace' to this method will cause the URL to update using 'replaceWith' instead. Omitting a parameter will disable the URL change, allowing for transitions that don't update the URL at completion (this is also used for handleURL, since the URL has already changed before the transition took place).

Parameters:

  • method String

    the type of URL-changing method to use at the end of a transition. Accepted values are 'replace', falsy values, or any other non-falsy value (which is interpreted as an updateURL transition).

Returns:

Transition:

this transition

retry

() Transition public

Retries a previously-aborted transition (making sure to abort the transition if it's still active). Returns a new transition that represents the new attempt to transition.

Returns:

Transition:

new transition

then

(
  • onFulfilled
  • onRejected
  • label
)
Promise public

A standard promise hook that resolves if the transition succeeds and rejects if it fails/redirects/aborts.

Forwards to the internal promise property which you can use in situations where you want to pass around a thennable, but not the Transition itself.

Parameters:

  • onFulfilled Function
  • onRejected Function
  • label String

    optional string for labeling the promise. Useful for tooling.

Returns:

Promise:

trigger

(
  • [ignoreFailure=false]
  • name
)
public

Fires an event on the current list of resolved/resolving handlers within this transition. Useful for firing events on route hierarchies that haven't fully been entered yet. Note: This method is also aliased as send

Parameters:

  • [ignoreFailure=false] Boolean optional

    a boolean specifying whether unhandled events throw an error

  • name String

    the name of the event to fire

Properties

data

Object public

Custom state can be stored on a Transition's data object. This can be useful for decorating a Transition within an earlier hook and shared with a later hook. Properties set on data will be copied to new transitions generated by calling retry on this transition.

promise

Object public

The Transition's internal promise. Calling .then on this property is that same as calling .then on the Transition object itself, but this property is exposed for when you want to pass around a Transition's promise, but not the Transition object itself, since Transition object can be externally aborted, while the promise cannot.
