contains environment-specific settings for the development environment. This file can be committed to version control as it should not contain secrets.
To get the most out of .env.local.production , follow these best practices:
Because .env.local.production is ignored by version control, other developers on your team won't know it exists or what variables it requires. Maintain an .env.example or .env.production.example file in your repository. This file should contain the necessary keys but leave the values blank or filled with placeholder data.
require('dotenv').config( path: `.env.local.$process.env.NODE_ENV`, ); .env.local.production
Assume you are running a production build locally for debugging:
Overriding defaults on a local machine for regular daily development. Production Only
If you need to test this build against live production databases or payment gateways (like Stripe production keys) instead of staging keys, you cannot put those keys in .env.production because that file is tracked by Git and shared with the team. Maintain an
The use of .env.local.production offers several benefits:
docker run --env-file ./docker/prod-override.env myapp:latest
.env.local.production is a local configuration file used to store environment variables that should only be active during a and only on a specific local machine . Production Only If you need to test this
has a robust built-in environment variable system with clear precedence rules. It supports all the standard file names and uses the NODE_ENV variable to determine which environment files to load. One crucial distinction is that server-side variables are read at runtime, while NEXT_PUBLIC_* variables are embedded at build time and become static strings in the JavaScript bundle. If a NEXT_PUBLIC_* variable changes, you must rebuild the application; simply changing it in your hosting environment is not sufficient.
Thus, .env.local.production (which is the same as .env.production.local ) is in production mode.
Since .env.local.production isn't in your repo, other developers (or your future self) won't know which variables are required. Maintain a .env.example file that lists the keys (but not the values) needed for the app to run. Example Scenario: Next.js
