syntaqxPages no longer blink as they refresh: a README stays put through a push, coloured diffs keep their colours, and production's picture is replaced rather than blanked. Markdown made its components for each commit (a README's pictures point at the commit shown), so every push to the branch had React take the whole README down and put it back; the components are now made once and read where links and pictures point from context, so a new commit only updates those addresses. A file in a diff (a commit, a pull request's changes, a comparison) dropped its colours on every refresh, since a refresh hands over a new file with the same lines, and drew them again when it scrolled near; it keeps them while its lines are the same. The production picture on a project's overview went back to its empty frame and "Taking a screenshot…" whenever its address changed (a new deploy) until the new one loaded; the old picture now stays under the new one until it has faded in. In Chat, every one of @g1t's answers was drawn afresh whenever a message arrived, since the repository they link into was compared as an object; it is compared by name. Router updates already run in a transition (React Router's RouterProvider wraps them in startTransition), so a refresh never shows a skeleton again once a page has loaded; that is measured below rather than changed. Checked: the site's typecheck, its 904 tests and a production build, and a harness that mounts the real routes with g1t.sh's own responses for flagon-io/g1t, decoded by React Router as the site does, watching the DOM over revalidations. Elements removed per 5 refreshes with the same data, before → after: commit page 2,495 → 0, every other page measured (overview, Code, a folder, a file, Commits, pull requests, issues, a pull request, an issue, Work, Workflows, a run, Deployments, and the same with the signed-in app shell) 0 → 0, with no skeleton shown again and no layout shift, also with deferred data taking 2.5 s. A push (a new head commit), per 4 refreshes: Code 1,077 → 0 (the README), overview's picture 18 removed and a skeleton shown → a 2-element cross-fade and none.8876797History
