Environment variables && npm scripts in some scenarios, it is useful to check the value of an environment variable before entering the node.js application in npm scripts. For example, if you want to use node-env-run when you are in a development environment, but node when you are in production. There is a tool that makes it very easy to do this: if-env .

Install it by running: bash copy the code npm install if-env --save make sure you don't install it as a "development dependency" as we will need it in production as 11-digit phone number format philippines well. Now you just need to modify your npm scripts in your package.json: json copy the code "scripts": { "start": ?? Npm run start:prod || npm run start:dev", "start:dev": "nodenv -f .



start:prod": "node ." } this script will then execute npm run start:prod, then node . If node_env has the value production, and otherwise will execute npm run start:dev, then nodenv -f .. You can also use this technique with any other environment variable. For example, try running: bash copy the code # should output "the value of foo is: bar" npm start # should output "the value of foo is: undefined" node_env=production npm start if you want to know more about if-env , check out its documentation .
