"I updated my .env.local file, but my app is still using the old values."

The primary purpose of .env.local files is to allow developers to override or add environment variables locally on their development machine without committing these changes to the version control system. This is particularly useful for: "I accidentally committed my

Vite uses dotenv under the hood to load environment files into your project root.

Your local machine rarely uses the same databases or third-party services as your production server. For instance, while production points to a live Stripe account, your .env.local points to a Stripe test key. This prevents accidental data corruption in production while you are writing features. 3.

Local overrides for all environments. This file overrides all other .env files except when running tests. By keeping local secrets local, developers can focus

Create a .env.local file for your personal local machine variables.

In this example, when you run your application locally, it will use http://localhost:8000 as the API URL, overriding the default value provided in .env . This way, you can work against a local API without altering the committed configuration.
