Approach to Implement dotenv npm
- We make a node project and install dotenv package. Create a ‘.env’ file and Environment variables as a key-value pair.
- Integration with Node.js is achieved by importing the dotenv package in the app.js file, and invoked dotenv.config() method. This method reads the .env file, parses its contents, and sets the environment variables in the Node.js runtime environment using process.env. These variables can be accessed throughout the application using process.env.VARIABLE_NAME.
NPM dotenv
Dotenv is a popular npm (Node Package Manager) package used in NodeJS applications to manage environment variables. Environment variables are values that are set outside of an application’s code and are accessible to the application during runtime. These variables often contain sensitive information like API keys, database connection strings, or configuration settings.
