Building apps using TanStack Start

Starting May 13, new projects built with Lovable will utilize Server-Side Rendering (SSR) and be powered by TanStack Start, a modern React framework designed for building fast, full-stack applications. This transition from Client-Side Rendering (CSR) with React + Vite to TanStack Start enhances search engine optimization (SEO) by serving pre-rendered content to crawlers, improves app performance by reducing load times, and simplifies the integration of server-side logic with client components. Existing projects continue as Single-Page Apps (SPAs) but benefit from improved crawler readability without requiring migration. TanStack Start's isomorphic design allows code to run seamlessly on both server and client sides, enhancing the development process by embedding server-only logic directly within component files and streamlining deployment. The framework's strong type system and adherence to SEO best practices, alongside Lovable's AI-driven code generation, result in a more secure and efficient development environment, with early results showing increased organic search traffic and improved performance from AI tools.
