An example of an AI chatbot conversation about managing configuration in Node.js applications.
How can I manage configuration in a Node.js application?
You can manage configuration in Node.js using environment variables, configuration files, or libraries like dotenv.
What is the dotenv library and how do I use it?
The dotenv library loads environment variables from a .env file into process.env. You can install it using npm.
Can you show me a simple example of using dotenv?
Sure! First, install it with npm install dotenv. Then, create a .env file with DB_HOST=localhost, and in your app, add require('dotenv').config(); to access process.env.DB_HOST.
Are there any other libraries for configuration management?
Yes, other popular libraries include config, convict, and nconf, each offering different features for managing configurations.
