uncaught

uncaught is the module, which allows you to handle all uncaught errors and promise rejections through only one listener.

How it works

uncaught listens for global object errors and unhandled rejections events:

For browser these are error and unhandledrejection.
And for Node.js these are uncaughtException and unhandledRejection.

After one of these events fires, the module transfers error (and also event for browser mode) object(s) to all registered listeners functions.

Usage examples

Browser

<body>
    ...
    <script src="path_to_your_project_dir/node_modules/uncaught/lib/index.js"></script>
    <script>
        uncaught.start();
        uncaught.addListener(function (error) {
            console.log('Uncaught error or rejection: ', error.message);
        });
    </script>
    ...
</body>

Browser + webpack

var uncaught = require('uncaught');

uncaught.start();
uncaught.addListener(function (error) {
    console.log('Uncaught error or rejection: ', error.message);
});

Node.js

var uncaught = require('uncaught');

uncaught.start();
uncaught.addListener(function (error) {
    console.log('Uncaught error or rejection: ', error.message);
});

API

List of methods for module management:

start Starts handling of uncaught errors and promise rejection.
stop Stops handling.
addListener Adds listener function to list. This function is called with uncaught error or promise rejection information:
- error object.
- In browser mode event object is sent as well.
removeListener Removes listener function from list.
removeAllListeners Removes all listeners functions.
flush Flushes the module: removes all listeners functions and stops handling of uncaught errors and promise rejections.
