.env file cannot be utilized in JavaScript

Currently, I am working on a project where both the front-end and server are located in one directory. I am using a .env file in the root directory, and the structure of the project looks like this:

project frontend (directory) server (directory) .env (file) When I reference process.env.PORT in the server, it works perfectly fine. However, when I try to reference process.env['PORT'] in the front-end, it returns "undefined".

Interestingly, when I start typing my variables, I do get hints for them https://i.sstatic.net/ouNKe.png

However, when I log them, they show up as undefined https://i.sstatic.net/iB4L9.png

Answer №1

process is a variable specific to Node.js and is not available in browser environments

It seems like you may be using dotenv. This package only populates process.env on the server side. To access environment variables on the client side, you will need to import them. Please provide more information on how your client code is structured so we can offer better guidance.

Personally, I prefer to use an env.json file at the root of my project instead of using dotenv and a .env file. I simply import the env.json file when I need to use its variables, eliminating the need for dotenv and making it work seamlessly on both the client and server side.
