Replace/Remove jQuery in 2.x

LuoTR

jQuery is quite large (https://bundlephobia.com/package/jquery@3.6.4) compared to Mithril itself (https://bundlephobia.com/package/mithril@2.2.10) and is not widely used in Flarum's frontend.

Many jQuery's features are not used very often since we have Mithril.

Also, Mithril itself requires at least IE11, making most of jQuery's compatibility code completely a waste.

So, I suggest we can replace jQuery with cash-dom (a much smaller alternative, https://bundlephobia.com/package/cash-dom@8.1.5), or just remove it if possible.

I can work on this if you think it's good to go.

looks like they already have plans to do such see: orgs/flarumprojects/22?pane=issue&itemId=5300309

LuoTR

Relic System I might just pick this up then 😃

I'm sure they would appreciate a PR that tackles one of the roadmap goals in an effective manner - good luck 🙂

Really appreciate the initiative @LuoTR 👍️

While the plan was to tackle this in 2.0, priorities change, so unfortunately this will have to wait until the next major version (3.0).

LuoTR

Sami (SychO) Actually, I've made some progress on rewriting jQuery parts and upgrading Bootstrap to v5.

However, for 2.0, is it possible to just replace it with something like cash-dom as a temporary solution? I'm not sure about its compatibility with Bootstrap v3 tho.

Sami (SychO)

LuoTR Sorry, it's another breaking change and too late to include now so it's very unlikely to get merged into the 2.x branch. It would be helpful to keep the changes around for the future though (3.0)

LuoTR

Sami (SychO) I'm still working on it, I will create a new branch and you can keep it as long as you like. 😃
