Polyfill implementation about proposal-intl-relative-time

[catamphetamine]

Update: Released Intl.RelativeTimeFormat polyfill as a separate package:
https://github.com/catamphetamine/relative-time-format

[catamphetamine]

Also your readme says that "polyfill is in progress".
I could provide the polyfill portion as part of my library since it's already working if you want in which case let me know.

Here's the polyfill.
The tests pass.
See if it fits.
I'm reopening this until response.

https://github.com/catamphetamine/javascript-time-ago/blob/master/source/RelativeTimeFormat.js
https://github.com/catamphetamine/javascript-time-ago/blob/master/source/RelativeTimeFormat.test.js

import JavascriptTimeAgo, { RelativeTimeFormat } from 'javascript-time-ago'
import en from 'javascript-time-ago/locale/en'

JavascriptTimeAgo.locale(en)
// Returns "2 days ago"
new RelativeTimeFormat('en').format(-2, 'day')

Great to hear about this polyfill! This is a great step towards helping people adopt the new API.

From the source, it looks like not all of the methods are implemented--I don't see an implementation of formatToParts, supportedLocalesOf, resolvedOptions, the type parameter, or numeric formatting options. Have you considered adding these?

I implemented formatToParts yesterday, have a look. As for the others, the readme doesn’t seem to say anything about them. Is there a document describing the full AI with examples?

Sorry, there aren't examples written out, but you can find descriptions of all the functions in the specification. I'll leave this bug open to remind me to improve the less formal API documentation here.

I don't see an implementation of formatToParts, supportedLocalesOf, resolvedOptions, the type parameter, or numeric formatting options.

• formatToParts - implemented
• supportedLocalesOf - implemented
• numeric="always"/"auto" - implemented
• resolvedOptions - added a basic version of it

From the README, this looks great! Do you want to make a PR to add a reference to this proposal's README?
