Today, Netlify is announcing On-demand Builders, a new solution that improves build times for large sites on Netlify. This release represents the first step forward in a significant evolution of the Jamstack architecture to support larger websites and faster development cycles across any JavaScript framework. The goal of On-demand Builders is to reduce build times so teams can iterate more quickly, while also enabling developers with huge sites to split their site's assets into critical content that's automatically compiled and deployed as part of their traditional Netlify build process, and deferred content built using an on-demand builder when a site visitor requests it for the first time. This approach is designed to work with any framework, including Next.js, Nuxt, and Eleventy, and can be used in various web projects such as e-commerce sites, publishing or media sites, and dynamic applications that generate content based on user request. On-demand Builders are currently available in early access with some constraints, but Netlify is enthusiastic about the future of this solution, which aims to address pressing issues facing developers building large sites and realize the full potential of Distributed Persistent Rendering.
