chore(deps): Upgrade Express to v5 in the FE server - #2583
chore(deps): Upgrade Express to v5 in the FE server#2583lisa-assistant wants to merge 3 commits into
Conversation
Express 4 is over a decade old and increasingly outside Express's own
support window. Renovate flags major bumps for manual approval, so
this one had been sitting unapplied since Express 5 stabilized.
Bumps express 4.22.2 -> 5.2.1 and @types/express 4 -> 5.0.6 in
@cedarjs/vite, and updates the bare wildcard route paths in
devFeServer.ts/runFeServer.ts to the named '/{*splat}' form Express 5
requires.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe Vite package upgrades Express and its type definitions to version 5. The development and production FE servers use pathless request middleware and named splat patterns for catch-all GET and POST routes. A changeset records the migration. ChangesExpress 5 front-end servers
Merge Risk: ⚪ Minimal · up to The Express 5 upgrade updates catch-all routing and middleware while the stated build, tests, lint, and formatting checks pass. Only a minor changeset wording update remains, so no actionable merge-blocking risk remains. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Rewrite the changeset body as a present-tense summary.
The body describes the migration timeline with past-state wording. State the current behavior and rationale directly: the FE servers use /{*splat} for catch-all GET and POST routes, and pathless app.use applies the per-request store to requests that reach the middleware.
As per coding guidelines: Markdown files must describe the present, not the history.
