Next js environment variables
To use environment variables in a Next.js application, you can follow the steps outlined below:
Step 1: Create a .env file
Create a file named .env
in the root directory of your Next.js project. This file will store your environment variables.
Step 2: Define the environment variables
Inside the .env
file, define your environment variables using the KEY=VALUE
syntax. For example, if you want to define a variable named API_URL
with the value https://example.com/api
, you would write API_URL=https://example.com/api
in the .env
file.
Step 3: Access the environment variables
In your Next.js code, you can access the environment variables using the process.env
object. For example, if you defined the API_URL
variable in the previous step, you can access it in your code using process.env.API_URL
.
Step 4: Restart the development server
After defining the environment variables, you need to restart the Next.js development server for the changes to take effect. Stop the server if it's already running, and then start it again.
Step 5: Use the environment variables
You can now use the environment variables in your Next.js application. For example, if you want to use the API_URL
variable from the previous steps, you can use it in your code like this: const apiUrl = process.env.API_URL
.
That's it! You have now set up and accessed environment variables in your Next.js application. Remember to keep your .env
file secure and avoid committing it to version control systems.
