nextjs environment file comment

nextjs

In Next.js, you can create an .env file in the root of your project to set environment variables that can be accessed by your code. These variables can be accessed using process.env.

For example, you might have a line in your .env file that looks like this:

API_URL=https://my-api.com

You can then access the value of API_URL in your code like this:

const apiUrl = process.env.API_URL;

Note that you will need to install the dotenv package and configure it to use the .env file in your project. You can do this by adding the following line at the top of your server.js file or next.config.js file:

require('dotenv').config();

This will allow you to access the variables defined in your .env file in your code.

You can also create a .env.local file to set environment variables for your local development environment, and a .env.production file to set environment variables for your production environment. These files will override the values set in the .env file.
