Define own chunking pagination function using JS (with variable chunk size)

[nhoizey]

Is your feature request related to a problem? Please describe.

I really don't like paginations using decimal increments, because every time I add new content, all these pages have changing content, while old archive pages should be really stable, both for SEO and UX (bookmarks for example).

I prefer archives per years and/or months.

Describe the solution you'd like

Being able to define my own JS function to slice the paginated data based on the date would allow that.

A slice callback could replace the size attribute (I don't see how they could co-exist), and be run after the new before callback.

So, instead of spliting ["item1", "item2", "item3", "item4"] into [["item1", "item2"], ["item3", "item4"]] (with size: 2), it would allow me to split ["2018-07-12-article1", "2018-12-13-article2", "2018-12-15-article3", "2019-03-23-article4"] into this for month pages:

[
  ["2018-07-12-article1"],
  ["2018-12-13-article2", "2018-12-15-article3"],
  ["2019-03-23-article4"]
]

I could then (I guess, maybe not) use the date of the first item in each slice to define the permalink.

Describe alternatives you've considered

The only other I can imagine right now is creating actual templates for each month/year I have published content (quite a lot, since 2001), and filter the content collections for each.

It would be really cumbersome to initialize, and it requires a new page every month.

@nhoizey I've made year and month collections (see an example here) - you can do it with custom collections.

You use a custom collection to create groups of items sliced how you like. You can then pass this collection to pagination to generate the individual pages.

I posted the code I use to do this in this thread.

Oh dang I like this idea. Practically speaking this would allow me to easily add a Day view to my Twitter archive (browse by tweets day) that I really like.

@edwardhorsford awesome, I'll check that right now! 👍

@zachleat good idea, I also plan to get all my tweets on my site, and daily view will be interesting, because I have quite a few… 😅

Some interesting notes on #2507 around a minimum chunk size for the last page (reminds me of CSS text-wrap: pretty, in a weird way)
