expressjsHow can I use dotenv with ExpressJS?
Using dotenv with ExpressJS is a great way to store environment variables in a secure manner. Environment variables are typically used to store sensitive information such as API keys and passwords, and dotenv provides a secure way of storing and retrieving them.
To use dotenv with ExpressJS, first install the dotenv package:
npm install dotenv
Next, create a .env
file in the root of your project and add your environment variables to it. For example:
DB_USERNAME=myusername
DB_PASSWORD=mypassword
Now, in your ExpressJS application, you can require the dotenv package and call the config()
method to load the environment variables from the .env
file.
require('dotenv').config();
You can then access the environment variables using process.env
, for example:
console.log(process.env.DB_USERNAME);
// Output: myusername
