Why is it that my Vue application's environment variables are easily visible in Google Chrome Inspector, instead of being hidden or encrypted?

Hey there everyone,

I recently completed building a Vue application, and everything seems to be functioning as expected when I run npm run build. However, upon inspecting the app using Google Chrome developer tools, I came across an interesting observation.

49650: function(e, t, r) {
            var i = r(74971);
            function a(e, t) {
                if ("string" === typeof e) {
                    if (["legacy", "regional"].indexOf(e.toLowerCase()) >= 0)
                        return e.toLowerCase();
                    throw i.util.error(new Error, t)
                }
            }
            // Other code snippets here...
        },

The functionality of the app is intact, but something caught my attention - the environment variables like VUE_APP_URL_API are displayed in clear text rather than being obfuscated.

Is there a way to address this concern? Any assistance on how to secure the variable values would be greatly appreciated.

I'm hoping for a solution where the values of each variable are properly encrypted or hidden from plain sight.

Answer №1

Is it possible to conceal environment variables in a client-side application? Unfortunately, no.

These variables must be visible to the client in order for the application to function correctly.
The only solution is to utilize a remote proxy on a backend server to protect this information.
