The second full reload command is related to vaadin-react.tsx not having support for HMR. By implementing support in a suitable way in https://github.com/vaadin/flow/blob/main/flow-server/src/main/resources/com/vaadin/flow/server/frontend/vaadin-react.tsx, the second reload changes into a HMR for /generated/vaadin-react.tsx, /generated/index.tsx

The first full reload command originates In the Hilla file router plugin:

hilla/packages/ts/file-router/src/vite-plugin.ts

Line 100 in ec4ba7f

server.hot.send({ type: 'full-reload' });
