How to Set .env with JS

Question

I have this, from https://npm.io/package/node-calendly-sdk.

calendly_client = new Calendly("YOUR-API-TOKEN")

I'm confused on how to set .env varibles in js

Answer 1

Env variables are a set of values, generally to store sensitive data that shouldn't be in the code.

In nodejs, you can add the npm package dotenv with: npm i dotenv, then, you have to create a file named .env in the root directory of your project and define your variable like:

.env file:

API_KEY_TOKEN = "some value"

Then, at the very beginning of your nodejs file, write: require("dotenv").config(); and that's it, you can access your .env variables with process.env

Full example:

require("dotenv").config();
calendly_client = new Calendly(process.env.API_KEY_TOKEN );
