Installation

npm install temporal-polyfill

A) Import globally:

import 'temporal-polyfill/global'

console.log(Temporal.Now.zonedDateTimeISO().toString())

B) Import as an ES module without side effects:

import { Temporal } from 'temporal-polyfill'

console.log(Temporal.Now.zonedDateTimeISO().toString())

C) The above techniques try using the built-in Temporal object and fall back to the polyfill. To guarantee using the polyfill, do this:

import { Temporal } from 'temporal-polyfill/impl'

console.log(Temporal.Now.zonedDateTimeISO().toString())

* = the size will shrink as the codebase is cleaned up

** = targets browsers that support BigInt, however, more browser-compatibility work is needed
