Relay is a powerful JavaScript framework developed by Meta (formerly Facebook), designed for efficiently managing GraphQL data in React applications. By abstracting GraphQL queries and managing caching, Relay optimizes data fetching and view rendering, providing a more seamless user experience. However, the framework has undergone significant changes over time, particularly with the introduction of Relay Modern to replace Relay Classic. In this article, we will explore and compare the key specifications of these two versions of Relay, highlighting their respective strengths and weaknesses.
1. Relay Classic vs Relay Modern: Key Differences The most notable difference in the Relay specifications lies in the two versions of the framework: Relay Classic and Relay Modern. While Relay Classic was the initial version and laid the foundation for Relay’s core functionality, Relay Modern offers a more streamlined, efficient, and flexible solution. Relay Classic: This version primarily relied on a traditional approach to managing data and queries. While it provided a stable and efficient framework for applications at the time, its structure became harder to maintain as the complexity of modern applications grew. Relay Classic is no longer recommended for new projects, as it has been officially deprecated by Meta.
