What’s the difference between SSR and CSR in modern frameworks?
Asked on Nov 12, 2025
Answer
Server-Side Rendering (SSR) and Client-Side Rendering (CSR) are two approaches used in modern web frameworks to render web pages. SSR generates HTML on the server and sends it to the client, which can improve initial load times and SEO, while CSR relies on the browser to render content using JavaScript, providing a more dynamic and interactive user experience after the initial load.
Example Concept: SSR involves rendering the HTML on the server and delivering a fully constructed page to the client, which can be beneficial for SEO and initial load performance. CSR, on the other hand, sends a bare-bones HTML page with JavaScript that builds the content dynamically in the browser, offering a more interactive experience but potentially slower initial load times.
Additional Comment:
- SSR is often used in frameworks like Next.js and Nuxt.js, which are built on top of React and Vue, respectively.
- CSR is typical in single-page applications (SPAs) using frameworks like React, Angular, and Vue.
- SSR can reduce the time to first meaningful paint, while CSR can lead to faster subsequent page interactions.
- Hybrid approaches, like static site generation (SSG), combine benefits of both SSR and CSR.
