Responsive SSR Architectures

Introduction

Server-Side Rendering (SSR) is a technique used in web applications to render content on the server rather than in the browser. This approach enhances performance and SEO by delivering fully rendered pages to clients upon request.

Key Concepts

SSR vs. CSR: SSR generates HTML on the server, while Client-Side Rendering (CSR) generates it in the browser.
Hydration: The process of attaching JavaScript event listeners to pre-rendered HTML.
Routing: Server-side routing versus client-side routing, impacting the user experience and performance.

Advantages of SSR

Improved SEO: Search engines can index fully rendered pages.
Faster First Load: Users receive HTML content quickly, reducing perceived load times.
Consistent Performance: SSR can reduce the load on client devices, especially on lower-end devices.

Design Principles

1. Component-Based Architecture

Utilize reusable components to manage complexity and promote code maintainability.

2. Data Fetching Strategies

Choose between static generation, server-side fetching, or client-side fetching based on the use case.

3. Responsive Design

Ensure that the UI adapts to various screen sizes using flexible layouts and CSS media queries.

Note: A mobile-first approach is recommended for responsive design.

Best Practices

Optimize server performance and response times.
Implement caching strategies at both server and CDN levels.
Use lazy loading for non-critical images and resources.
Monitor and log performance metrics to identify bottlenecks.

FAQ

What is SSR?

What are the disadvantages of SSR?

SSR can increase server load and complexity in managing server-side code compared to CSR.
