An example of an AI chatbot conversation about accessing environment variables in Express.
How do I access environment variables in an Express app?
You can access environment variables in an Express app using the process.env object. For example, process.env.PORT will give you the port number.
What if I want to set default values for these variables?
You can use the dotenv package to load environment variables from a .env file. Just create a .env file and use require('dotenv').config(); at the top of your main file.
Can I access these variables in my route handlers?
Yes, you can access environment variables in your route handlers the same way, using process.env.VARIABLE_NAME.
Is it safe to store sensitive information in environment variables?
Yes, it's generally safe to store sensitive information in environment variables, but ensure your .env file is not included in version control.
