Last active December 23, 2022 08:53
Clearing the console alone is not enough, and a better approach is to disable the developer tool from being opened in any meaningful way
(function() {
'use strict';
Object.getOwnPropertyNames(console).filter(function(property) {
return typeof console[property] == 'function';
}).forEach(function (verb) {
console[verb] =function(){return 'Sorry, for security reasons...';};
});
window.addEventListener('devtools-opened', ()=>{
// do some extra code if needed or ...
// maybe even delete the page, I still like to add redirect just in case
