Interface HookMatchCriteria

Each property (to, from, exiting, retained, and entering) can be a state Glob string, a boolean, or a function that takes a state and returns a boolean (see HookMatchCriterion)

All properties are optional. If any property is omitted, it is replaced with the value true, and always matches. To match any transition, use an empty criteria object {}.

Example:

// This matches a transition coming from the `parent` state and going to the `parent.child` state.
var match = {
  to: 'parent',
  from: 'parent.child'
}

Example:

// This matches a transition coming from any substate of `parent` and going directly to the `parent` state.
var match = {
  to: 'parent',
  from: 'parent.**'
}

Example:

// This matches a transition coming from any state and going to any substate of `mymodule`
var match = {
  to: 'mymodule.**'
}

Example:

// This matches a transition coming from any state and going to any state that has `data.authRequired`
// set to a truthy value.
var match = {
  to: function(state) {
    return state.data != null && state.data.authRequired === true;
  }
}

Example:

// This matches a transition that is exiting `parent.child`
var match = {
  exiting: 'parent.child'
}
