What shipped

The final polish batch for the Next.js port landed overnight — five issues covering error handling, performance, UX safety nets, and mobile responsiveness. These were the last items in the “Next.js port” milestone.

Error handling and loading states were added to all server actions and forms, so users now see proper feedback instead of silent failures. The dashboard and account balance calculations had N+1 query patterns that were fixed by adding eager loading and missing database indexes — page loads should be noticeably faster with real data volumes.

Delete actions across the app (accounts, transactions, contacts, categories, promises, statements, projects) now show confirmation dialogs before destructive operations. A hamburger menu was added for mobile viewports, making the sidebar collapse and expand properly on small screens. Finally, Content-Disposition filenames were sanitized to prevent path traversal, and unused shadcn components were cleaned out to reduce bundle size.

Completed

• #52 — Add error handling and user feedback to all server actions and forms
• #53 — Fix N+1 query pattern in dashboard and account balance calculations
• #54 — Add confirmation dialogs to all delete actions
• #55 — Add mobile-responsive sidebar with hamburger menu
• #56 — Sanitize Content-Disposition filenames and remove unused shadcn components

Release progress

• Next.js port: 0 open / 18 closed (milestone complete)
• March 2026: 0 open / 0 closed (empty — predates the port)

Carry-over

• The repo migration happened on 2026-03-23: simplebooks renamed to simplebooks-rails (archived), simplebooks-next became the new simplebooks. The new repo is live on GitHub but needs a fresh npm install after the directory rename (stale node_modules references to old path). The Next.js dev server has Turbopack errors related to missing next/dist/pages/_error and global-not-found modules — likely needs a clean node_modules reinstall.
• No milestones exist on the new repo yet — the old milestones lived on simplebooks-rails.
• CLAUDE.md needs updating for the Next.js codebase (currently has Rails-era content from /init).

Risks

• The SQLite database (db/simplebooks.db) was migrated from the Rails/Postgres dump but has no auth tables (users, companies) — the Next.js port is single-tenant. If multi-tenancy is needed later, the schema will need rework.

Flags and watch-outs

• The node_modules were installed when the project lived at ~/Projects/simplebooks-next. Some cached paths still reference that old location. A clean rm -rf node_modules && npm install in the new location should fix the Turbopack errors.
• The package.json still has "name": "simplebooks-next" — should be updated to "simplebooks".
