An example of an AI chatbot conversation about Ruby Dotenv for managing environment variables.
What is Ruby Dotenv and how do I use it?
Ruby Dotenv is a gem that loads environment variables from a .env file into your Ruby application. It helps manage configuration settings.
How do I install Ruby Dotenv?
You can install it by adding gem 'dotenv' to your Gemfile and running bundle install. Alternatively, you can install it directly using gem install dotenv.
Can you show me an example of a .env file?
Sure! A .env file might look like this:
DATABASE_URL=postgres://user:password@localhost/dbname
API_KEY=your_api_key_here
Just make sure to add .env to your .gitignore file!
How do I access these variables in my Ruby code?
You can access the variables using ENV['VARIABLE_NAME']. For example, ENV['DATABASE_URL'] will give you the database URL.
