Master the Mystery: What is the .env- File and How Do You Use It? Next.js natively supports .env.development

While almost every developer is familiar with the standard .env file used to store local environment variables, a newer convention has steadily gained traction: the naming pattern.

Managing environment variables is a fundamental part of modern software development. While most developers are familiar with the standard .env file, the use of prefixed or suffixed variations—often referred to under the umbrella of .env- patterns—is crucial for handling complex deployment pipelines, security, and team collaboration.

Next.js natively supports .env.development , .env.production , and .env.test . While it uses a dot ( .env.production ) rather than a hyphen, the concept remains identical. It requires the NEXT_PUBLIC_ prefix for client-side variables.
