.env.local.production May 2026

For example, in a Next.js project, you might have:

The .env.local.production file would contain key-value pairs specific to your production environment that are not version-controlled. For instance:

NEXT_PUBLIC_API_URL=https://api.example.com
SECRET_API_KEY=your_secret_key_here

Loader (Node example)

require('dotenv').config( path: '.env.local.production' )

To understand the outlier, you must first understand the standard. Most frameworks (Next.js, Vite, React Native, Django, Laravel) follow a similar loading order. Files are loaded in sequence, with later files overriding earlier ones.

The typical hierarchy looks like this:

Notice the last one: .env.production.local . This is the species to which .env.local.production belongs. They are essentially the same file with the words rearranged, though different frameworks prefer different patterns. .env.local.production

Most developers are familiar with the standard environment file flow:

This works fine until you need to run a production build on your local machine.

Why would you do this? Maybe you are debugging a performance issue that only appears in the minified build, or you want to test API integrations against a staging or production database without changing your standard development config. For example, in a Next

If you run npm run build (which usually looks for .env.production), you might accidentally use committed, dummy values. Or, you might find yourself constantly editing .env.production locally and hoping you don't accidentally commit your real API keys.

Here is a production-grade template for managing your env files.

A typical .env.local.production file might look like this: Loader (Node example) require('dotenv')
