esbuild-plugin-env

ESBuild plugin (v1.1.1, maintained) that loads environment variables using dotenv and makes them available via process.env at build time. Key differentiators: automatically sets NODE_ENV based on minify flag, provides PROD/DEV boolean constants, supports custom key prefix (default ESB_), and allows overriding production detection. Ships TypeScript types. Alternative to @jvdx/esbuild-plugin-env or manual define replacements.
