: Environment-specific local overrides.
To "make" or create a .env.local file for your project, you essentially create a plain text file that stores local environment variables (like API keys or database URLs) that should stay on your machine and not be shared. How to Create a .env.local Locate Your Project Root
The standard solution across the web development ecosystem is using environment variables. Among the various configuration files you might encounter, .env.local plays a specific and crucial role.
Below is an example of what a .env.local file might look like. This example assumes you're working on a project that uses environment variables for API keys, database connections, or feature flags: .env.local
# .env.local (Developer A) DATABASE_URL="postgresql://localhost:5432/dev_a"
The .env.local file is a plain text file used by developers to store environment variables locally. Environment variables are key-value pairs that configure your application's behavior without altering the codebase.
Older React apps built with Create React App look for the REACT_APP_ prefix. require('dotenv')

In this example, the .env file defines general environment variables that apply to both development and production environments. The .env.local files define environment-specific variables that override or complement the general variables. Can’t copy the link right now
Since .env.local isn't tracked by Git, new developers won't know which variables they need to set. Create a .env.example file with the keys but dummy values (e.g., API_KEY=your_key_here ) and commit that instead.
