Electron.js perguntas e respostas de entrevista
Pergunta 1. What is Electron.js?
Electron.js is an open-source framework developed by GitHub for building cross-platform desktop applications with web technologies like HTML, CSS, and JavaScript.
Pergunta 2. Explain the main process and renderer process in Electron.
The main process manages the lifecycle of the application and creates web pages using renderer processes. Renderer processes are responsible for rendering the UI and run in separate instances for each opened window.
Pergunta 3. How can you communicate between the main process and renderer process in Electron?
Inter-process communication (IPC) is used to communicate between the main process and renderer processes. Electron provides modules like 'ipcMain' and 'ipcRenderer' for sending and receiving messages.
Pergunta 4. Explain Electron's 'Main' and 'Renderer' threads.
The 'Main' thread manages the Electron application and runs the main script. The 'Renderer' thread runs the web page content and is responsible for rendering the UI. Each Electron window has its own 'Renderer' thread.
Pergunta 5. What is the purpose of the 'preload' script in Electron?
The 'preload' script is a JavaScript file specified in the Electron BrowserWindow options. It runs in the renderer process and has access to Node.js APIs before the DOM content is loaded. It allows customization of the environment for the renderer process.
