Theres occurring a problem.
This library relies on the Twig_Extension Bundle.

But the Twig/Extensions Bundle is abandoned.
"WARNING: This repository is abandoned in favor of Twig Core Extra extensions."
Source: https://github.com/twigphp/Twig-extensions

The function, that this bundle here is using isn't in the Twig Core Extra extension:
"DateExtension: time_diff filter -> no equivalent"

Has anybody a solution how to make this bundle (or a similar bundle) compatible?

Really, timeago.js may be part of the solution here. But I'm unclear on what the best practices are using Webpack Encore and requiring a javascript library in a bundle.

What I've been doing is

yarn add timeago

Then

Any idea on how to require a js library from within a Symfony Bundle, and integrate it (automatically?). Then the twig extension becomes easy, at least for that part.

Thats because you need to install twig extension bundle (composer require twig/extensions)

But Twig Extension Bundle is incompatible with SF5 ("Your requirements could not be resolved to an installable set of packages.")

So this knp time bundle can't be installed right now.

Should be better in v1.11.0. If you have any problems, please open a new issue :)
