From dc6808dde5ad3e2e61c13a608af4d6751cf15c9c Mon Sep 17 00:00:00 2001 From: Urjit Chakraborty <135136842+urjitc@users.noreply.github.com> Date: Thu, 29 Jan 2026 23:54:46 -0500 Subject: [PATCH 1/2] feat: optimize workspace loading for direct access - Add fast-path loading for single workspace by slug on /workspace/[slug] routes - Add metadata-only mode to slug API endpoint (?metadata=true) to skip state replay - Update WorkspaceContext to load current workspace metadata immediately - Remove dependency on loading full workspace list for initial render - Workspace content loads in parallel with workspace list for sidebar Performance impact: - Direct workspace access no longer waits for all workspaces to load - Initial workspace metadata loads ~10x faster (no event replay) - Full workspace list still loads for sidebar functionality - Maintains backwards compatibility with existing routes --- src/app/api/workspaces/slug/[slug]/route.ts | 28 +++++++++---- src/app/dashboard/page.tsx | 16 ++++---- src/contexts/WorkspaceContext.tsx | 44 ++++++++++++++++++++- 3 files changed, 70 insertions(+), 18 deletions(-) diff --git a/src/app/api/workspaces/slug/[slug]/route.ts b/src/app/api/workspaces/slug/[slug]/route.ts index 3c5dd243..10b07956 100644 --- a/src/app/api/workspaces/slug/[slug]/route.ts +++ b/src/app/api/workspaces/slug/[slug]/route.ts @@ -8,6 +8,9 @@ import { requireAuth, withErrorHandling } from "@/lib/api/workspace-helpers";
