Our Optimization Techniques Explained

Static Generation vs. Server-Side Rendering
We utilize both Static Site Generation (SSG) and Server-Side Rendering (SSR) strategically, depending on the use case:
SSG is used for content that doesn’t change frequently, allowing us to generate static HTML at build time for lightning-fast load times.
SSR is employed for pages that require real-time, personalized content. By delivering these dynamically rendered pages as needed, we ensure user-specific data is fresh without sacrificing speed.
For many projects, we implement a mix of Incremental Static Regeneration (ISR) to provide a balance between static performance and content freshness, ensuring your pages stay up-to-date without costly server rebuilds.
To further optimize SSR and client-side rendering, we focus on keeping client-side code to a minimum. Reducing the amount of JavaScript that runs on the client side significantly improves load times and responsiveness, creating a more efficient and faster user experience. This is achieved through techniques like lazy loading non-critical components and server-side handling of as much logic as possible to avoid overwhelming the client browser. For example, in a health industry portal project, we leveraged SSR to ensure real-time accuracy for user-specific educational content while using SSG for static sections, significantly improving the balance between performance and personalization.
Code Splitting and Bundle Analysis
Code splitting is a powerful technique that helps minimize load times by breaking down JavaScript bundles into smaller pieces:
We utilize dynamic imports in Next.js, meaning that code only gets loaded when it's needed, rather than upfront. This makes your website lighter and improves the Time to Interactive (TTI).
Our team performs regular bundle analysis to identify and eliminate unused code or oversized dependencies. By integrating tools like Webpack Bundle Analyzer, we ensure that the application remains optimized and doesn’t burden the end-user with unnecessary payload.
Common issues we address during bundle analysis include oversized third-party dependencies or redundant JavaScript that can significantly bloat the bundle. For example, replacing a large analytics library with a lightweight alternative resulted in a 30% reduction in bundle size and a noticeable improvement in load times.
Edge Functions and Middleware
Edge functions and middleware allow us to move computation and processing closer to users, effectively reducing latency:
Edge Middleware is used to execute lightweight operations, such as redirects and authorization, before the request hits the main server, making responses faster for the user.
We implement solutions like Vercel Edge Functions and Cloudflare Workers to manage resource-heavy computations at the edge, resulting in improved responsiveness and user satisfaction.
Additionally, by serving assets and responses from edge locations closest to the user, we lower the Time to First Byte (TTFB), improving overall load times for users across the globe.
For example, by offloading JWT token validation to the edge using Cloudflare Workers, we reduced the load on the main server and improved authentication response times, providing a more seamless user experience.
Third-Party Script Management
Third-party scripts can have a major impact on performance, and optimizing them is key to maintaining speed:
We audit and manage third-party scripts by using tools like Chrome DevTools to determine which scripts are essential. Unused scripts are removed, and critical ones are optimized.
Where possible, scripts are loaded using async or defer attributes to prevent blocking the main rendering path. We also implement lazy loading for non-essential scripts, which reduces the initial page load burden and speeds up user interactions.
For instance, working on an e-commerce project, we removed non-essential third-party scripts, resulting in an 18% improvement in load speed.
