electron-extended-WebExtensions
Extend the built-in functionality of Electron Web Extensions with additional features commonly used by browsers.
Application APIs
Here's what you need to use in order to integrate this module
const { ExtendedExtensions } = require('electron-extended-WebExtensions')
// Pass in an Electron `Session` object you wish to attach to.
// If you're not sure, use the default one `session.defaultSession`
const extensions = new ExtendedExtensions(session, {
// Handle when the system expects a new tab to be created
// `popup` is set to `true` when it's a popup for a browser action
// `openerTabId` is set to the id of the parent tab (if applicable)
// You should return an Electron WebContents instance so it can be tracked
onCreateTab: async ({url, popup=false, openerTabId}) => WebContents,
})
// Pass an absolute path to load an extension
// This will also attach necessary injected APIs to it
const extension = await extension.loadExtension(path)
// You can unload an extension at runtime by passing it's id
await extensions.unloadExtensions(extension.id)
// Listen for context menu events and get the list of menu items to add
webContents.on('context-menu', (event, params) => {
const extensionMenuItems = extensions.contextMenus.getForEvent(webContents, event, params)
// You might want to add some of your own context menu items
// Could be useful in combination with https://github.com/sindresorhus/electron-context-menu
Menu.buildFromTemplate(extensionMenuItems).popup()
})
// When you set up browser windows, you'll likely want to render browser actions
extensions.browserActions.list()
// Extensions may set custom browser actions for a tab
// You can fetch the tab-specific actions with this:
extensions.browserActions.list(webContents.id)
// Browser Action objects look something like this:
const action = {
// Track this to notify the system of clicks
extensionId,
extensionURL,
// Disabled items aren't usually listed
enabled: true,
// This text is usually displayed as image alt text upon hovering
title,
// This is the popup URL if one exists
// Mostly handled internally by the system
popup,
// This is the "badge text", it can get update periodically
text: '0',
// This is the icon you should render for the browser action
icon: 'chrome-extension://idhere/image.png',
}
// When users click on the Browser Action UI, notify the system with this:
// The `webcontents.id` should be the id of the web contents that the click was performed for (the active tab)
extensions.browserActions.click(extensionId, webContents.id)
TODO
Items with a question mark might not happen or are low priority
- Try to reuse the Electron Extensions API
- Manifestv2
- Support APIs used by WebRecorder
- Support background pages - x Spawn background page - x Provide extension APIs to it - x Tabs - x Debugger - x Context Menu - x Browser Action - x webRequest (doesn't work on custom protocols yet, built in)
- Support content scripts
- x Run content scripts (doesn't work on custom protocols yet, built in)
- x Provide extension APIs
-
runtime.connect
and friends - Support popup APIs
- Support BrowserActions - x Ability to specify BrowserAction in manifest - x List browser actions from electron app, listen for triggers - x Send browser action event to background page - x Open link on browser action - chrome.browserAction.setBackgroundColor
- contextMenu API - x create() - x update() - x remove() - x onClicked() - Support url patterns for filtering (todo)
- webNavigation API - x onBeoreNavigate - x onCommitted - x onDOMContentLoaded - x onCompleted - x onErrorOccured - x getFrame() - x getAllFrames() - Support url patterns for filtering (todo) - historyStateUpdated/createdNavigationTarget,referenceFragment will be TODO
- Extend Tabs API: - x Built in support has sendMessage, reload, executeScript, update - x get, query, create, remove - x onActivated/onCreated/onRemoved/onUpdated - x executeScript got overrided in order to support custom protocols (for Agregore) - captureTab? - insertCSS / removeCSS? - getCurrent? - goBack/goForward?
- Support debugger API needed by WebRecorder
- Support interacting with pages using Custom Protocols Handlers
- Notifications API? https://www.electronjs.org/docs/latest/api/notification
- Other APIs? Open an issue or a PR.
