In electron how to send custom header and value for every request?

Question

I use electronjs for building a cross platform desktop application. I would like to send a custom header with a value for every request from electron. Initially in loadURL(), i could use extraHeaders to set the custom header. How to send it in all subsequent requests?

As recommended by the documentation, you should use session object and the method onBeforeSendHeaders:

const { session } = require('electron')

// Modify the user agent for all requests to the following urls.
const filter = {
  urls: ['https://*.github.com/*', '*://electron.github.io']
}

session.defaultSession.webRequest.onBeforeSendHeaders(filter, (details, callback) => {
  details.requestHeaders['User-Agent'] = 'MyAgent'
  callback({ requestHeaders: details.requestHeaders })
})
