It is a wrapper of the Javascript console: with tee-console.js it is possible to add an additional function to handle console messages. It prints the message via the default console function and it does something more with the it.
A complete and useful example is available in the index.html page.
The following is the minimal code needed to see tee-console.js in action.
<script type="text/javascript" src="tee-console.js"></script>
<script type="text/javascript">
console.setMyConsoleAction((message) => { alert(message) });
console.info('this is an info message');
</script>The expected output of the script above is:
- a default
console.infoprinted message in the browser console - an
alertmessage showing the same text of the console
tee-console.js wraps default methods [log, info, warn, debug] of the Javascript console and re-triggers them transparentrly, but then, right after the original function call, it triggers a custom function.
The goal is to leave unchanged the original behavior in order to have events triggering the console as expected by default. The additional value is to be able to handle the console message as well, to have for instance the possibility to do a server logging via an Ajax POST.
