addEvent / removeEvent
Imperative event-listener helpers. Use them outside JSX (in effects, lifecycles, or standalone code) when you need DOM.addEventListener-like control but tied to the reactive scope.
# addEvent Arguments
Returns an off() function that removes the listener. The same removal is also registered as a cleanup on the current reactive scope, so the listener is torn down automatically when the scope is disposed — you don't have to call off() manually in most cases.
| name | type | description |
|---|---|---|
| node | node | reference to the node on which to add the event listener |
| type | string | event listener to add, example click. Types are case sensitive, as regular event listeners |
| handler | fn | {handleEvent:fn, once?:bool, passive?:bool, etc?:bool} | handler to run once the event is triggered |
# removeEvent Arguments
Returns a handy on function that uses no arguments, to add the event back
