From 37a989af442a2f3788669d3e767e0d17f1d76768 Mon Sep 17 00:00:00 2001 From: Valerii Kovalskii Date: Sun, 19 Jul 2026 22:21:43 +0300 Subject: [PATCH] =?UTF-8?q?feat:=20Workspace=20browser=20terminal=20?= =?UTF-8?q?=E2=80=94=20B-0=20walking=20skeleton=20(v7.7.0)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a real terminal in the browser (new "Workspace" view) as the first step of the TermDeck merge. Single pane for now; splits, tmux-less reattach, saved commands and per-project workspaces come next. Architecture (optional feature — core stays dependency-free): - src/terminal.js: lazily loads @lydell/node-pty (prebuilt-only, no node-gyp) and hand-rolls the WebSocket on the stdlib http.Server 'upgrade' event, so `ws` is NOT a dependency. Binary frames carry raw terminal bytes; text frames carry JSON control (resize/ready/exit). - Security: a per-process token + same-origin Origin check gate the WS (it grants shell access), and cwd must pass isSafeLaunchPath. Safe to run in server mode. - server.js: server.on('upgrade') wiring, GET /api/terminal/status (reports availability + serves the token same-origin), a strict allowlisted GET /vendor/* static route (xterm.js served lazily so the base dashboard never carries the ~490KB bundle), and ws:/wss: added to connect-src CSP. - Frontend: src/frontend/workspace.js lazy-loads the vendored xterm.js + fit addon, opens the WS, wires stdin/stdout/resize; nav item, render() dispatch, NAV_HELP entry, teardown on leaving the view, themed CSS. - @lydell/node-pty in optionalDependencies; CLAUDE.md updated to reflect the one optional dep. Vendored @xterm/xterm 6.0.0 + addon-fit (MIT). Tests: 9 new unit tests for the WS frame codec + token compare. Verified end-to-end in a browser (real zsh round-trip, bad-token rejection, teardown on navigate). Full suite 166 pass / 2 skipped / 0 fail.
