Exposing parameter types for standalone listeners outside of addListener #72
Description
Currently the parameters for addListener are inlined, i.e. types/hints are available only in an inline listener:
chrome.webNavigation.onHistoryStateUpdated.addListener(info => { ...... });but we can't use types in a standalone listener function outside of addListener (e.g. to toggle it somewhere else):
chrome.webNavigation.onHistoryStateUpdated.addListener(onNav);
function onNav(info) { ...... }Here's the current generated code for reference:

export const onHistoryStateUpdated: CustomChromeEvent<(
callback: (
details: {
/**
* The ID of the tab in which the navigation occurs.
*/
tabId: number,
url: string,
/**
* The ID of the process that runs the renderer for this frame.
*/
processId: number,
/**
* 0 indicates the navigation happens in the tab content window; a positive value indicates navigation in a subframe. Frame IDs are unique within a tab.
*/
frameId: number,
/**
* The ID of the parent frame, or `-1` if this is the main frame.
*
* @since Chrome 74
*/
parentFrameId: number,
/**
* Cause of the navigation.
*/
transitionType: TransitionType,
/**
* A list of transition qualifiers.
*/
transitionQualifiers: TransitionQualifier[],
/**
* The time when the navigation was committed, in milliseconds since the epoch.
*/
timeStamp: number,
/**
* A UUID of the document loaded.
*
* @since Chrome 106
*/
documentId: string,
/**
* A UUID of the parent document owning this frame. This is not set if there is no parent.
*
* @since Chrome 106
*/
parentDocumentId?: string,
/**
* The lifecycle the document is in.
*
* @since Chrome 106
*/
documentLifecycle: extensionTypes.DocumentLifecycle,
/**
* The type of frame the navigation occurred in.
*
* @since Chrome 106
*/
frameType: extensionTypes.FrameType,
},
) => void,
filters?: {
/**
* Conditions that the URL being navigated to must satisfy. The 'schemes' and 'ports' fields of UrlFilter are ignored for this event.
*/
url: events.UrlFilter[],
},
) => void>;Suggesting to auto-generate a dummy type for each object parameter:
export const onHistoryStateUpdated: CustomChromeEvent<(
callback: (details: OnHistoryStateUpdatedDetails) => void,
filters?: OnHistoryStateUpdatedFilters,
) => void>;These dummy types would be also exported, so we can use them in typescript:
chrome.webNavigation.onHistoryStateUpdated.addListener(onNav);
function onNav(info: chrome.webNavigation.OnHistoryStateUpdatedDetails) { ...... }as well as in jsdoc:
chrome.webNavigation.onHistoryStateUpdated.addListener(onNav);
/** @param {chrome.webNavigation.OnHistoryStateUpdatedDetails} info */
function onNav(info) { ...... }
