Can Browserslist add a parameter for the current time?

[SilentTiger]

The configuration of mine is "last 6 years". I am curious to discern the discrepancy between the outcome of executing this query today and the result of conducting the same query the previous year.

It seems a little bit similar to #680

We can add environment variable for that. Please send PR.

@ai could you give me more details about the environment variable

Here is section of our docs:

https://github.com/browserslist/browserslist#environment-variables

And a small brief about the whole idea

https://en.wikipedia.org/wiki/Environment_variable

@ai furthermore, have you ever thought about make it can be run in browser?

[ai]

@SilentTiger you can use webpack/vite options to set environment variable for client-side bundle.

But I don’t think it will be popular to replace current time in browser.

[SilentTiger]

@ai oh, I mean not only the environment variable in browser, but also the whole Browserslist, thus maybe the https://browsersl.ist/ won't need a backend for query.

[ai]

Browserslist supports working in browsers except >10% in Ru query, because statistics for all countries will bloat JS bundle size.

I've added the first commit about this feature, the environment variable has been added, and the "last_years" query has been modified. Can you give me some suggestions, I just want to know if I was on the right way.

Thanks.

Looks good. Please create PR for deeper analysis.

[SilentTiger]

Thanks!

I think the "last_years" is not the only query that will be affected by this modification, I'll check other queries, and this will take time.
