There's no way you can get a device unique id from the browser; but you can generate one yourself upon startup and save it into localStorage for later re-use!
function generateUUIDV4(): string {
// http://www.ietf.org/rfc/rfc4122.txt
const s = []
const hexDigits = '0123456789abcdef'
for (let i = 0; i < 36; i++) {
s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1)
}
s[14] = '4' // bits 12-15 of the time_hi_and_version field to 0010
// eslint-disable-next-line no-bitwise
s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1) // bits 6-7 of the clock_seq_hi_and_reserved to 01
s[8] = s[13] = s[18] = s[23] = '-'
const uuid = s.join('')
return uuid
}
