lifecycle-hook cljs

Dev-only extension point for dev/x-trace-history. Holds a 1-arg function called on each lifecycle callback (connected, disconnected, attribute-changed). nil by default — each callback site is a single atom-deref + nil check when off.

make-element-class cljs

(make-element-class {:keys [observed-attributes connected-fn disconnected-fn
                            attribute-changed-fn form-associated?
                            form-disabled-fn form-reset-fn setup-prototype-fn
                            internal?]})

Create a custom element class from a declarative options map.

Required keys: :observed-attributes — #js [...] array of attribute names :connected-fn — (fn [el] ...) called on connectedCallback :attribute-changed-fn — (fn [el name old new] ...) called on attributeChangedCallback

Optional keys: :disconnected-fn — (fn [el] ...) called on disconnectedCallback :form-associated? — true to mark as form-associated element :form-disabled-fn — (fn [el disabled?] ...) called on formDisabledCallback :form-reset-fn — (fn [el] ...) called on formResetCallback :setup-prototype-fn — (fn [proto] ...) install properties/methods on prototype :internal? — when true, skip firing the dev-tool lifecycle hook on every callback. Set this on elements that are themselves part of the dev tooling (e.g. the x-trace-history dock); otherwise their own connect/disconnect/attribute records would pollute the trace they produce.
