About the Client
Yapsody is an online event ticketing platform that allows event organizers to create, manage, and sell tickets for concerts, festivals, conferences, and other live events, with support for reserved seating, box office sales, attendee check-in, and sales reporting. The online ticket store frontend was originally built on AngularJS, which limited performance and search engine visibility. The frontend was migrated to Next.js, a React-based framework that supports server-side rendering and static site generation. Post-migration, the application recorded a Lighthouse Performance score of 98% and an SEO score of 100%, along with improved maintainability of the codebase.
Business Context
The online ticket store was built on AngularJS, a framework officially deprecated by Google in December 2021. Continued reliance on the framework led to growing technical debt, including slow page load times, limited search engine indexing, and reduced flexibility for ongoing development.
Challenges
Maintaining feature parity during a full frontend rebuild
Rebuilding the frontend from AngularJS to Next.js required recreating all components, routes, and user interactions without affecting the live platform. The migration had to ensure that no existing functionality was lost or altered during the transition.
Adapting dynamic ticketing flows to pre-rendered architectures
The platform relied on dynamic data such as event listings, seat maps, and real-time ticket availability. Aligning these with server-side rendering and static generation required deciding which parts could be pre-rendered and which needed real-time data handling.
Making content crawlable without slowing down the interface
The client-side rendering approach limited search engine visibility. Moving to pre-rendered pages required restructuring content delivery so that pages were indexable while still loading quickly and behaving responsively for users.
Solutions We Implemented
Incremental rebuild with parallel validation against the live system
The new frontend was developed in stages, with individual components rebuilt and tested independently before integration. A parallel validation approach ensured that each feature in the Next.js codebase matched the existing AngularJS behaviour before final deployment.
Hybrid rendering model based on data stability and freshness
Rendering strategies were defined at the page level. Static generation was used for stable content such as event listings, while server-side rendering handled pages dependent on real-time data like seat availability. This separation ensured both performance and data accuracy.
Pre-rendered architecture with structured SEO implementation
Pre-rendering capabilities were used to deliver fully crawlable HTML for search engines. Page structures were updated with semantic markup and metadata configurations, improving indexing while maintaining a fast, client-side user experience.
Impact
Significant Performance Gains
The migration to Next.js resulted in significantly faster page loads and improved core web vitals, achieving a Lighthouse Performance score of 98%.
Full SEO Visibility
Replacing client-side rendering with server-side rendering made all pages fully crawlable by search engines, resulting in a perfect Lighthouse SEO score of 100%.
Improved Codebase Maintainability
Moving away from the deprecated AngularJS framework to a modern, actively supported Next.js codebase reduced technical debt and positioned the platform for easier long-term development and scaling.
