esbuild-plugin-auto-env

An esbuild plugin that automatically replaces environment variable references in source code with values defined at build time. Current stable version is 0.3.0, released September 2023. Update cadence is irregular. Key differentiators: supports glob-based include/exclude patterns for fine-grained control, allows ignoring specific environment variables, and replaces with undefined in browser mode. Alternative to manual Define or envsubst approaches. Ships TypeScript types.
