    Mount Events can inform you about certain stages of the Node's lifecycle, letting you perform the required initialization / cleanup.

    Mount Events can inform you about certain stages of the Node's lifecycle, letting you perform the required initialization / cleanup.

    They are also used internally for managing the lifecycle of stream subscriptions.

    A Node is considered mounted if it's present in the DOM, i.e. it has dom.document among its ancestors. A node that is not mounted is considered unmounted.

    All MountEvent-s are cascading: if a certain event is fired on a node, it will also fire on all descendants of that node.

    NodeDidMount event fires when a previously unmounted (or newly created) node becomes mounted.

    NodeDidMount event fires when a previously unmounted (or newly created) node becomes mounted.

    Internally, Laminar will activate the node's subscriptions when it's mounted.

  2. object NodeWasDiscarded extends MountEvent

    NodeWasDiscarded event fires after NodeWillUnmount unless the end user specified that the node should not be discarded when it's unmounted.

    NodeWasDiscarded event fires after NodeWillUnmount unless the end user specified that the node should not be discarded when it's unmounted.

    A discarded node is defined as a node that is unmounted and will not be mounted again. The latter is a promise by the end user, not enforced by Laminar.

    Internally, when discarding a node Laminar kills all of the subscriptions that it owned. NodeWasDiscarded event is your last chance to do any cleanup related to this node.

    Note: There currently is no way for the end user to specify that the node should not be discarded, so the end user implicitly promises to not re-mount nodes which have been unmounted.

  3. object NodeWillUnmount extends MountEvent

    Permalink

    NodeWillUnmount event fires when a previously mounted node is about to be unmounted.

    NodeWillUnmount event fires when a previously mounted node is about to be unmounted. Note: when the even fires the node is still mounted.

    Internally, Laminar will deactivate the node's subscriptions when it's unmounted, except for the internal subscription that listens to mountEvents (so that we can re-activate the other subscriptions when the node gets mounted again).

    Note: currently, every NodeWillUnmount event is followed by a NodeWillBeDiscarded event which deactivates the subscription that listens to mountEvents
