How to Build a SaaS Dashboard with Next.js (Stable Delivery Playbook)

Start with auth boundaries: who sees which routes, and how sessions refresh. Sketch that before charts.

Next.js App Router or Pages both work; consistency matters more than trend. Pick one data-fetching pattern and stick to it so junior contributors are not guessing.

Tables beat charts on day one. Operators want sortable, filterable data. Pretty graphs come after the CSV export works.

Instrument errors early: failed API calls should surface to you, not only to a silent console.

Ship a thin vertical slice (one role, one workflow end to end) before you widen scope. Dashboards balloon; slices keep them shippable.

If your existing dashboard is unstable, run a short triage first. Most high-risk failures can be diagnosed within one to three days with proper boundary mapping.
