RENDERER for Electron Window: Browser View

Allow the renderer to use browserView with ElectronWindow

NPM link: @el3um4s/renderer-electron-window-browser-view

Use @el3um4s/ipc-for-electron and @el3um4s/electron-window to allow communication between Electron and a web page

Install and use the package

To use the package in a project:

npm i @el3um4s/electron-window

Then in a file:

import ElectronWindow from "@el3um4s/electron-window";
import windowControls from "@el3um4s/renderer-for-electron-window-controls";

const createWindow = async (options: {
  url: string;
  preload: string;
  themeSource?: "system" | "light" | "dark";
  settings?: Electron.BrowserWindowConstructorOptions;
}): Promise<ElectronWindow> => {
  let window: ElectronWindow;

  const { url, themeSource = "system", preload } = options;

  const settings = {
    ...options?.settings,
    title: "GEST DASHBOARD",
  };
  window = new ElectronWindow(settings);

  window.createWindow({ url, themeSource, preload });

  await window.setIpcMain([windowControls]);

  await window.addBrowserViewHidden();
  await window.setIpcMainView([windowControls]);

  window.addAutoUpdater();
  return window;
};

let electronWindow: ElectronWindow;

electronWindow = await createWindow({
  url,
  preload,
  themeSource: "light",
  settings: {
    x: Math.floor(Math.random() * 64),
    y: Math.floor(Math.random() * 64),
  },
});

To use in the renderer install:

npm i @el3um4s/electron-window @el3um4s/renderer-electron-window-browser-view  @el3um4s/ipc-for-electron

Then in the preload file:

import { generateContextBridge } from "@el3um4s/ipc-for-electron";
import { browserView } from "@el3um4s/electron-window";

const listAPI = [browserView];

generateContextBridge(listAPI, "ipc");

Then in the renderer:

import browserView from "@el3um4s/renderer-electron-window-browser-view";

browserView.openInBrowserView({ url: "https://www.google.com", apiKey: "ipc" });

browserView.showBrowserView({
  bounds: {
    paddingLeft: 64,
    paddingTop: 64,
    paddingRight: 128,
    paddingBottom: 128,
  },
  apiKey: "ipc",
});

browserView.on.browserViewCanBeShowed({
  callback: (data) => {
    console.log(data);
  },
});

API: main process

new ElectronWindow(settings?: Electron.BrowserWindowConstructorOptions):ElectronWindow: create a new instance of ElectronWindow

import ElectronWindow from "@el3um4s/electron-window";

let window: ElectronWindow;

import ElectronWindow from "@el3um4s/electron-window";

let window: ElectronWindow;

const options = {
  url: "https://www.google.com",
  themeSource: "light",
  preload: "path/to/preload.js",
};

window = new ElectronWindow();
window.createWindow(options);

async setIpcMain(api: Array<IPC>): Promise<void>: set the ipcMain for the window

Use el3um4s/ipc-for-electron (GitHub, NPM) to set the ipcMain for the window

import ElectronWindow from "@el3um4s/electron-window";
import windowControls from "@el3um4s/renderer-for-electron-window-controls";

• el3um4s/renderer-for-electron-auto-updater (GitHub, NPM)

npm i @el3um4s/electron-window @el3um4s/ipc-for-electron @el3um4s/ipc-for-electron-auto-updater @el3um4s/renderer-for-electron-auto-updater

In the main process:

import ElectronWindow from "@el3um4s/electron-window";

let window: ElectronWindow;

window = new ElectronWindow();
window.createWindow();

window.addAutoUpdater();

In the preload file:

import { generateContextBridge } from "@el3um4s/ipc-for-electron";

const listAPI = [autoUpdater];

generateContextBridge(listAPI, "ipc");

  bounds: {
    paddingLeft: 64,
    paddingTop: 64,
    paddingRight: 64,
    paddingBottom: 64,
  },
};

await window.addBrowserView(options);

async addBrowserViewHidden(options?: CreateBrowserView): Promise<void>: add a browserView to the window and hide it

import ElectronWindow from "@el3um4s/electron-window";

let window: ElectronWindow;

window = new ElectronWindow();
window.createWindow();

const options = {

  preload: "path/to/preload.js",
};

await window.addBrowserViewHidden(options);

async setIpcMainView(api: Array<IPC>): Promise<void>: set the ipcMain for the browserView

import ElectronWindow from "@el3um4s/electron-window";
import systemInfo from "@el3um4s/ipc-for-electron-system-info";

let window: ElectronWindow;

window = new ElectronWindow();
window.createWindow();
