next-env-dotenv

A simplified implementation of Next.js's next-env package using dotenv. This package loads environment variables from .env and .env.${process.env.NODE_ENV} files.

Features

• Loads .env and .env.${process.env.NODE_ENV} environment files
• Supports variable expansion using dotenv-expand
• Does not override existing environment variables
• Compatible with Next.js's @next/env API

Installation

npm install next-env-dotenv

Using it instead of @next/env

Add to package.json:

{
  ...
  "overrides": {
    "next": {
      "@next/env": "@huksley/[email protected]"
    }
  }
}

Install NextJS again: npm i next@16

Differences from Next.js's next-env

This version loads:

If NEXT_ENV_FILE specified, will load that file instead of NODE_ENV

• .env.${process.env.NEXT_ENV_FILE} - if NEXT_ENV_FILE is specified
• .env.${process.env.NODE_ENV} - if NODE_ENV is set and NEXT_ENV_FILE is not specified)
• .env

The original Next.js implementation also loads:

• .env.local
• .env.NODE_ENV.local
• Additional environment-specific files
