Sometimes you have to use other values in a variable when your application is in production as if when you are debugging it. For example you have to use another web service URL.
Here is how can do it:
var webApiUrl;
if (process.env.NODE_ENV === "production") { // use in production webApiUrl = "http://myapp.online/awesome-app/api"; } else { // use on debugging webApiUrl = "/api"; }
If you do it like me and use Webpack, you can start the debug mode with webpack -d
and the production mode with webpack -p
.
