removeEventListener

removeEventListener

Removes a previously registered event listener.

Signature

removeEventListener(eventName: string, callback?: (value: any) => void): Promise<void>

Parameters

Parameter	Type	Required	Description
eventName	string	Yes	Name of the event
callback	function	No	The callback function to remove. If not provided, removes all listeners for this event name

Returns

Promise<void>

Usage

// Define callback as a named function
const handleClick = (value) => {
  console.log("Clicked:", value);
};

// Add listener
await api.addEventListener("product_clicked", handleClick);

// Remove specific listener
await api.removeEventListener("product_clicked", handleClick);

// Or remove ALL listeners for this event
await api.removeEventListener("product_clicked");

Notes

• To remove a specific listener, pass the exact same function reference used in addEventListener()

• Anonymous functions cannot be removed individually — store the function in a variable first

• Call without callback to remove all listeners for the given event name
