# ENV Provider

When building an application, you may want different configuration based upon the environment your code is running in.

To fulfill this requirement, Expresswebjs uses the dotenv library.

Inside the root of every new Expresswebjs project, you’ll find an .env.example file.

You can create your .env file and set up you environment configuration. To do that on terminal, run:

cp example.env .env

Expresswebjs helps you have a maintainable codebase by providing a dedicated location for storing application configuration.

ExpresswebJs uses the config directory, where all files are loaded at boot time.

You can access configuration values in the App/Config directory
