How can I improve the initial load time of my web application?
Asked on Jan 19, 2026
Answer
Improving the initial load time of a web application involves optimizing various aspects of the front-end and back-end to ensure faster delivery of content to users. This can include techniques like code splitting, lazy loading, and server-side rendering.
- Minimize and compress assets such as JavaScript, CSS, and images using tools like Webpack or Gulp.
- Implement lazy loading for images and components to defer loading until they are needed.
- Use server-side rendering (SSR) with frameworks like Next.js to improve perceived performance.
- Leverage browser caching and set appropriate cache headers to reduce redundant network requests.
- Optimize the server response time by using efficient database queries and employing caching strategies.
Additional Comment:
- Consider using a Content Delivery Network (CDN) to distribute assets closer to users.
- Analyze performance bottlenecks using tools like Google Lighthouse or WebPageTest.
- Ensure that critical CSS is loaded first to improve render times.
- Evaluate third-party scripts and remove or defer non-essential ones.
