SSG vs SSR in Next.js Web Applications: Choosing the Right Rendering Approach

Blog



This article compares Static Site Generation (SSG) and Server-Side Rendering (SSR) in Next.js applications, helping developers choose the right approach for their use case.

  • SSG pre-renders HTML at build time; ideal for static content with fast load times
  • SSR generates HTML on-demand per request; better for dynamic, personalized content
  • SSG offers speed and CDN scalability; SSR provides real-time data and personalization
  • Choose SSG for infrequent content updates; SSR for frequently changing dynamic content
  • SSG build times scale with page count; SSR has latency and scalability challenges
  • Both approaches deployable via AWS Amplify with example code provided
  • Next.js allows mixing SSG and SSR on different pages within same application

The choice between SSG and SSR depends on content frequency, SEO needs, user experience requirements, and acceptable trade-offs between performance and dynamic functionality.
