Electron.js 面试题与答案
问题 11. Explain the concept of 'Electron Prebuilt' and 'Electron' packages.
'Electron Prebuilt' and 'Electron' packages are npm packages that provide Electron binaries. 'Electron Prebuilt' is an older version, while 'Electron' provides the latest stable release. Developers can use these packages to run Electron apps without having to manually install Electron globally.
问题 12. How can you handle menu creation in Electron?
Menus in Electron can be created using the 'Menu' module. You can define menu items, submenus, and their functionality. Menus can be attached to specific windows or the application as a whole.
问题 13. What is Electron's 'autoUpdater' module used for?
The 'autoUpdater' module is used to enable automatic updates for Electron applications. It allows apps to check for updates and download new versions from a server.
问题 14. Explain how Electron handles security and sandboxing.
Electron uses the Chromium browser, which employs a multi-process architecture with a main process and renderer processes. Each renderer process is sandboxed to enhance security, preventing direct access to Node.js modules and system resources.
问题 15. What is the 'contextIsolation' option in Electron and why is it used?
The 'contextIsolation' option, when set to true, isolates the renderer processes by running JavaScript code in a separate context. This enhances security by preventing the renderer processes from directly accessing the 'require' function and other Node.js modules.
