Gatsby, a performance-focused framework, has introduced a significant optimization for large-scale applications by splitting the global page manifest into individual page-specific files to enhance loading times and interactivity. This change addresses the issue where large manifests, in applications with over 5,000 pages, caused slow navigation and interaction due to the significant data load required before any user interface actions could occur. By creating a separate page-data.json for each page, which includes necessary metadata like the React component name and GraphQL query results, Gatsby eliminates the need for a monolithic manifest, thus improving metrics like Time to Interactive (TTI) and reducing perceptible lag in navigation. This update, available in Gatsby v2.9.0, also benefits hosting platforms like Netlify by reducing rebuild times, supports future incremental build capabilities, and remains fully backward compatible, enabling users to maintain fast and efficient site performance simply by upgrading to the latest version.
