Question: Does unpoly support merge of the head content? #296
|
I used unpoly and i noticed when I switch between pages if the new page has new content in the head it isn't merged with the old. Does unpoly support this feature by some config or api? |

Unpoly will merge |

@janreges I wouldn't be the one making the call to add this to Unpoly (it would be @triskweline). I'm reasonably neutral on the feature itself. |

I'm interested in solving this, in particular to better support splitting large asset bundles without a build tool that can do chunks (like Webpack). However if Unpoly is to have a stronger opinion over how assets (JavaScripts and stylesheets) are delivered, it must either have a solid design or offer a lot of configuration to fit everyone's use case. Some of decisions that need to be made:
Everyone has an answer for these questions in their own projects, but it differs wildly across users.
I have seen htmx' head merging extension. Unfortunately that approach wouldn't work for my own apps without heavy modification. I don't know Turbo's implementation. |

We would also need to distinguish between assets (JS, CSS) and other elements in the head. Assets would need to be updated for every render pass, since they may be needed to compile new fragments. However, elements like |

@triskweline - in two days HTMX will include I think that basically it contains the most essential functions. A few days ago I developed a multi-swap extension for HTMX https://htmx.org/extensions/multi-swap/. I will also try to help expand the head-merge extension. It needs to be more configurable to handle some edge cases, but I believe we can handle it. I will then try to project my acquired knowledge from development in HTMX into development in Unpoly. Both HTMX and Unpoly are great libraries and I see the ability to merge the as really essential. Especially with the advent of access like Astro or Qwik, Unpoly can also gain popularity. |

@triskweline - HTMX already released plugin This implementation is apparently different from the one you looked at in the past - it could have come from a 2-year-old branch that was just someone's attempt. You can check this current implementation https://github.com/bigskysoftware/htmx/blob/master/src/ext/head-support.js Do you see any flaws in this implementation that would prevent it from working in your applications that you mentioned? I consider this implementation to be flexible and allow solving various specific needs in projects. |

I would like to reimplement the merging functionality from HTMX to Unpoly as well. I would process it separately and then send a PR including docs update. @triskweline - as the lead author of Unpoly and its internal architecture, could you describe to me in 2-3 sentences where in Unpoly's architecture you would put this functionality? For now, I implement it by catching the I will be very grateful for any ideas and suggestions you have on how to grasp the implementation. I believe that I will then be able to deliver a PR that will not be too much work for you :-) |

@janreges Thank you for offering to help with this. I spend many evaluating possible approaches to reconcile The result is RFC: Reconciliation of Also it's perfectly fine if you just want to port HTMX' implementation. You can do so in a plugin that hooks into the |
