Intercepting a console.log created by a node_module to display in a toast-CodePudding

I am trying to use a console.log() created from within a node_module to display a toast on screen for the user.

I have my toasts working. I'm just not sure how to capture the log message since it is not being created from my personal code. Is this possible?

CodePudding user response：

WARNING: This is extremely bad practice. It is not recommended to change the behavior of a native function especially not console.log.

That being said you can technically intercept logs by redefining the log function and then using console.info to still log things.

console.log = function(...args) {
   alert("logged")
   console.info(...args);
}

I recommend forking the NPM package instead and implementing your own logic.

CodePudding user response：

Override the global console's log method with a method named log that you define:

var previous = console.log;
console.log = function() {
    // Do whatever you need here:
    // call your own function with the original arguments
    yourFunction.apply(thisObj, arguments);
 
    // do the normal console.log if you want
    previous.apply(thisObj, arguments);
};
