Dotenv won't override them.Deploying an application requires developers to put thought and consideration into how it is configured. Many apps are deployed in a development environment before being deployed to the production environment. We need to ensure each environment is configured correctly, it could be disastrous if our production application was using our development database, for example.

Environment variables allow us to manage the configuration of our applications separate from our codebase. Separating configurations make it easier for our application to be deployed in different environments. Large applications tend to have many environment variables. To better manage them we can use the dotenv library, which allows us to load environment variables from a file.

From programming we know that variables are stored values that can be changed. They're mutable and can vary - hence the name variables. Environment variables are variables external to our application which reside in the OS or the container of the app is running in. An environment variable is simply a name mapped to a value. By convention, the name is capitalized e. The values are strings.

If you open the terminal or command line application in Linux, Mac OS, or Windows and enter setyou will see a list of all environment variables for your user. Environment variables are excellent for decoupling application configurations.

Typically, our applications require many variables to be set in order for them to work. By relying on external configurations, your app can easily be deployed on different environments. These changes are independent of code changes, so they do not require your application to be rebuilt to change. Data which changes depending on the environment your app is running on should be set as environment variables.

Some common examples are:. Sensitive data like API keys should not be in the source code, or known to persons who do not need access to those external services.

Consider a hello world Node.

The Dotenv Component

Create a new file called hello. It is expecting the hostname and the port that the app will run on to be defined by the environment. You will notice the following message on your console:. Creating and reading environment variables is that easy. Let's say we are writing a micro-service which communicates with a MySQL and Redis instance, we would like to have the connection details available in our environment variables as well. Developing with multiple environment variables quickly become unwieldy.

It would be better if the environment variables we had to configure were stored in one central place to the application, like a file. This library does one simple task: loads environment variables from a. Let's use dotenv for the previous example. Now in the same directory of your app, create a new file called.

Your environment variables are declared just as if you were entering them in the shell before running the node command. Instead of separating each variable assignment by a space, we separate them by a newline. Now in your shell, if you enter node hello. Even if dotenv is used in the application, it is completely optional.

If no. You can continue to use environment variables defined outside the file. Note : There are also many variations of dotenv across other programming languages and frameworks.
