dsh-composer-scroll-hide

A DSH browser-side plugin that makes the composer follow the message flow while scrolling.

Features

Scroll up: the input bar slides off-screen at the same speed as the content, so it never covers the history you are reading
Browsing history: while paging down through history, the input bar stays hidden — it never pops in early
Back to latest: the input bar only rides back in over the final stretch of the return to the latest message (about one composer height), settling fully at the bottom
Float tracking: the app's "back to bottom" float button moves together with the input bar and lands 16px above the bottom edge once the bar is fully hidden

dshpm install github:wanglaixiang-cyber/dsh-composer-scroll-hide --profile

For local development, link the package into a profile:

"dsh-composer-scroll-hide": "link:/path/to/dsh-composer-scroll-hide"

Edits to lib/client.js are picked up by client-hmr within about a second — no page refresh, no restart.

Listens to scroll events on the [data-conversation-scroll] scrollport (passive — never blocks scrolling)
Composer offset = min(distance to bottom, composer height): position-driven, so any state (re-attach, jump, resize) converges on the next scroll
Syncs the --dsh-composer-height custom property, which drives the back-to-bottom float's clearance so the float tracks the bar
The seat height is cached via ResizeObserver; the transform is written at most once per frame (requestAnimationFrame)
