0.3.2 • Public • Published

webext-menus

A library helping you create dynamic menus in webextensions. Used by Image Picka.

Installation

Via npm

npm install webext-menus
const webextMenus = require("webext-menus");
const menus = webextMenus([
  {
    title: "My command",
    contexts: ["browser_action"]
  }
]);

Pre-built dist

You can find it under the dist folder, or download from unpkg.

Compatibility

If the browser supports the visible property when creating the menu item, the library update the item when oncontext is changed.

Otherwise, the library destroy/recreate the item to hide/show the menu.

API reference

This module exports a single function to initialize a dynamic menu.

webextMenus

webextMenus(options: Array<Object: MenuProps>, useVisible: Boolean | null)
  => ({update: () => void})

options is an array of property object for menus.create. The property object may contain following properties:

  • Any property used by browser.menus.create.
  • checked - function, which should return a boolean indicating whether the menu item should be checked. If checked is not a function, it is considered static.
  • oncontext - function, optional. oncontext should return a boolean indicating whether the menu item should be shown.

useVisible decides whether to hide menu items by updating the visible property. If false, it will remove/recreate the menu item to mimic hide/show effect. If undefined or null, it will use the visible property if supported.

Note: There is an empty menu bug in Chrome so I suggest setting this argument to false.

The function returns an object with an update method. When called, it invokes each item's oncontext/checked and show/hide/toggle the menu item.

update is usually hooked to a change event. For example:

// assume there is a preference library
const menus = webextMenus([
  {
    title: "My command",
    contexts: ["pages"],
    onclick: () => console.log("clicked"),
    oncontext: () => pref.get("shouldShowCommand")
  }
]);
pref.onChange(() => {
  menus.update();
});
