isDev():
boolean
Defined in: internal/dev.ts:15
Internal
Dev-mode predicate. Returns true unless process.env.NODE_ENV is
"production".
The bare process.env.NODE_ENV token is read on purpose: bundlers (Vite,
esbuild, webpack) replace exactly that token with a string literal at build
time, so a production build folds the predicate to false in a browser as
well as in Node. A typeof process guard would defeat the fold, because
after replacement it would be the only reference to process left and a
browser has none. Loading the packages in a browser without a bundler is
not supported and throws a ReferenceError on the first call.
