Simple cross origin requests in Electron

electron-fetch-via-main

Why

This module helps you bypass restrictions when making cross origin requests in renderer process, by delegate the requests to main process.

Install

npm install electron-fetch-via-main

Usage

Note that this module only work with contextIsolation: false

In main process

import { setupMainFetchlistener } from 'electron-fetch-via-main'

setupMainFetchlistener()

In preload scripts, expose fetchViaMain to renderer

import { fetchViaMain } from 'electron-fetch-via-main'

window.fetchViaMain = fetchViaMain

In renderer process, just replace fetch with fetchViaMain

const resp = await window.fetchViaMain('https://...', {
  method: 'POST',
  body: { ... },
})

// read json
await resp.json()

// streaming response
for await (const chunk of resp.body) {
  ...
}
