How do I use environment variables in Next.js?
An example of an AI chatbot conversation about using environment variables in Next.js.
How do I use environment variables in Next.js?
In Next.js, you can use environment variables by creating a .env.local file in your project root. You can define your variables there.
What format should I use for the variables in the .env.local file?
You should use the format NEXT_PUBLIC_VARIABLE_NAME=value. Variables prefixed with NEXT_PUBLIC_ will be exposed to the browser.
Can I access these variables in both server and client code?
Yes, you can access them in server-side code directly, and in client-side code, only those prefixed with NEXT_PUBLIC_.
What if I want to use different variables for development and production?
You can create different .env files like .env.development and .env.production, and Next.js will automatically use the appropriate one based on your environment.
