isDev
isDev():
boolean
Defined in: internal/dev.ts:12
Internal
Dev-mode predicate. Returns true unless the bundler/runtime has marked
the build as production (process.env.NODE_ENV === "production").
Vite, esbuild, webpack, and tsup all replace process.env.NODE_ENV at
build time with a string literal when NODE_ENV is set, which lets the
if (isDev()) guarded warning paths be tree-shaken out of minified
production bundles.
