One note on approach. The review discussion on #15971 raised that the #15574-style environment handling would be more fool proof than per-module |

Thanks! You're alright. The regression was my fault.

Since 2.63.1 (#15971), the init script's eager
import('/@vite/client')was gated onDEVfromesm-env, which folds onNODE_ENV— soNODE_ENV=staging vite buildshipped the dev bootstrap in production output (#16008). Sorry for the regression (awkward emoji face + that one emoji with a sweat drop) #15971.As @Rich-Harris suggested in #16008, this goes back to the
import.meta.hottrick, but in the generated clientapp.jsinstead of per kit module. All user client code is imported throughapp.js, so Vite injecting its client as that module's first dependency guarantees thedefineglobals exist beforehooks.client.js(or anything else) evaluates — static import order, with no possibility of the race the eagerimport()left open. This also keeps #13249 fixed. The start graph already has the same guarantee via the preamble inclient.js.render.jsnow emits no dev-only code at all. The remainingesm-envDEVgates in the runtime still fold with a non-standardNODE_ENV.Fixes #16008
