When Flarum's assets are rebuilt (a deploy, an extension toggle), the running page notices — every API response carries an X-Flarum-Assets-Revision header, and if it differs from the one the page booted with, Flarum pops up a dismissible

A new version of this page is available. [Reload]

That alert appears immediately, right in the middle of whatever you were reading or typing. On a busy forum whose assets change often, it can feel like it's constantly nagging you to reload.

Seamless Refresh takes a gentler approach, proposed by luceos on the Flarum tracker: when newer assets are detected, it doesn't interrupt you at all — it just quietly remembers. The next time you actually navigate — click a link, open a discussion, use back/forward — the browser does a normal full page load of that destination, so the fresh assets come along for the ride. No modal, no timing guesswork, no risk of wiping a draft.

Never interrupts a reading or typing user — nothing appears mid-session.
Always up to date — your very next navigation is already on the new assets.
Zero configuration — enable it and you're done.
No backend — it only changes how the frontend reacts to the revision header Flarum already sends.

How it works

Flarum core detects the new revision in ForumApplication.checkAssetsRevision and shows the alert. This extension overrides that method to set a flag instead of alerting, and registers a capture-phase click listener: while the flag is set, an internal same-origin link click is turned into a full page load (window.location.assign) so the destination boots with the new assets. Back/forward (popstate) reloads too.

It deliberately does not touch: modified clicks (Ctrl/⌘/Shift/middle — "open in new tab"), target="_blank" / download links, in-page anchors (#…), javascript: / mailto: / tel: links, or external links. It also never fires while you're just reading or typing — only a real navigation triggers the refresh, and the browser's own "unsaved changes" guard still protects an open composer.

Install

composer require ernestdefoe/seamless-refresh

Then enable Seamless Refresh in Admin → Extensions. There are no settings.

The behaviour is a direct implementation of the "refresh on the next natural interaction" idea luceos proposed as a middle ground between always interrupt and never warn. If you like it, it's also being proposed for Flarum core.
