Vite-hosted Nitro services
Added- Before
- Vite integration did not exist
- After
- Vite hosts configured Nitro services
Vite projects can register Nitro-backed SSR and API services, including Vue and React examples. The plugin creates Nitro and service environments, routes requests to configured services, and builds client assets into Nitro’s public output.
In favour
- In favour: Shares Vite’s build pipeline with Nitro services
- In favour: Routes service requests through one generated dispatcher
The model found nothing to weigh against this.
Development worker coordination
Modified- Before
- Worker types lived with dev server
- After
- Worker types are shared publicly
Development servers now use shared worker lifecycle, request, upgrade, and messaging contracts. They forward traffic to ready workers, relay messages, and record worker addresses in build information.
In favour
- In favour: Centralizes worker lifecycle and messaging contracts
Against
- Against: Creates a two-way dependency between shared types and development code
