Problem Description
I want to use Session to resolve hostnames using DNS-over-HTTPS setup with configureHostResolver():
import { app, session } from 'electron';
app.whenReady().then(() => {
configureHostResolver({
enableBuiltInResolver: false,
secureDnsMode: "secure", // Forced use of DNS-over-HTTPS servers only
secureDnsServers: [
"https://8.8.8.8/dns-query", // Google
"https://1.1.1.1/dns-query", // CloudFlare
"https://9.9.9.9/dns-query" // Quad9
]
})
session.defaultSession.resolveHost("google.com", {
source: "???", // What source should be used to ensure that DNS-over-HTTPS is using?
queryType: "A"
})
})Proposed Solution
Add more info for such case to the Session doc
Alternatives Considered
Not applicable
Additional Information
Struggling to find the answer by inspecting the codebase. Need help of Electron dev team.
