Preload & IPC
Lesson 2 of 5
Preload scripts and contextBridge expose a narrow, hand-picked API to the page, and invoke/handle carries requests to main and answers back.
What you'll learn
- Expose a minimal API to the page with a preload script and contextBridge
- Round-trip requests with ipcRenderer.invoke and ipcMain.handle
- Understand why nodeIntegration stays off and contextIsolation stays on
