How to open new window in place of current window in Electron

Opening a new window to replace the current one in Electron is a common operation, especially when developing multi-window applications. I will detail how to implement this functionality below.

Step 1: Create a New Window

First, we need to create a new BrowserWindow instance. This new window can use a different HTML file or the same as the current window, depending on your application's needs.

javascript
const { BrowserWindow } = require('electron');

function createNewWindow() {
    let newWin = new BrowserWindow({
        width: 800,
        height: 600,
        webPreferences: {
            nodeIntegration: true
        }
    });

    newWin.loadURL('https://example.com/new-page.html'); // Load content for the new window
    return newWin;
}

Step 2: Replace the Current Window

Next, we need to close the current window and display the new one. There are several approaches to achieve window replacement; a straightforward method is to close the current window immediately after creating the new one.

javascript
const currentWindow = BrowserWindow.getFocusedWindow();  // Get the currently focused window

function replaceWindow() {
    const newWin = createNewWindow();

    // Ensure the new window is ready before closing the current window
    newWin.on('ready-to-show', () => {
        currentWindow.close();  // Close the current window
        newWin.show();          // Show the new window
    });
}

Example

Suppose we are developing an application where users need to be redirected to a new confirmation page after completing a task. We can call the replaceWindow function after the user submits a form, which will transition the user from the current task window to the confirmation window, rather than opening a new window layered over the existing one.

Notes

• Ensure proper handling of resource release and data persistence issues when closing windows.
• Consider fallback strategies for when the new window fails to load, based on your application's requirements.
• If your application supports multi-window operations, ensure the window management logic is correct and robust.

By using the above methods, you can effectively replace the current window in an Electron application, providing users with a smooth and consistent interface experience.
