Performance, security, and Lighthouse: how we keep the bar objective.

Users feel performance before they read a word. Security issues show up as distrust, SEO loss, or an emergency weekend. Wissing Development treats both as measurable product requirements, not polish at the end of a timeline.

Lighthouse and Core Web Vitals

Lighthouse (in Chrome DevTools, PageSpeed Insights, or CI) gives a structured view: LCP, CLS, INP, accessibility hints, and best-practice flags. We run it on representative pages and on key templates, not only the marketing homepage. Targets depend on the project, but we agree them early: for example strong LCP on hero routes and tight JS budgets on content pages.

Lighthouse is not gospel: lab scores differ from field data. Where it matters, we pair it with real-user monitoring or Search Console field metrics so we optimize what your audience actually experiences.

Security in the same pipeline

Baselines include dependency updates, safe headers where applicable, careful handling of secrets and env config, and sane auth/session patterns for anything logged-in. We avoid shipping obvious OWASP foot-guns (injection, broken access control, XSS-friendly templates) and document assumptions for anything that needs a formal audit later.

What you get before go-live

A short performance and security checklist tied to your launch: what we measured, what we fixed, and what to watch after release. That way "production ready" means something we can both point to, not a vibe.
