Vite becomes the shared dev layer while Rolldown replaces multiple bundlers to give 3–16× production build speedups and simpler chunking; Oxc (the Oxidation compiler) supplies a parser 3× faster than SWC and 5× faster than Bun’s parser, a resolver ~20× faster than enhanced-resolve, transformer/minifier and DTS emitter, and Oxlin provides linting 50–100× faster than ESLint; a real run shows Oxlin finishing in 22.5s across 264,925 files with 101 rules, and migration can be as simple as swapping the vite alias to the Rolldown package.
