Client-Side Rendering (CSR)
Rendering UI in the browser via JavaScript — fast subsequent navigations, but slow first load and bad SEO without workarounds.
In long form.
Pure CSR ships an empty HTML shell plus a JavaScript bundle; the browser runs the JS, fetches data, and renders the UI client-side. The penalty: users (and crawlers) see a blank page until the JS executes, which is bad for SEO and bad for users on slow connections or low-end devices. CSR makes sense for authenticated dashboards, embedded widgets, and tools where SEO doesn't matter. For public marketing content, server-rendered or static is almost always better.
We use CSR sparingly — for interactive components inside an otherwise server-rendered page (a glossary filter, a contact form with validation), not for whole pages. The 'use client' directive in Next.js scopes the JS bundle to just the interactive parts.
