Simple and fast logger for client-side errors


# Global
npm -g install kaldr
# Local
npm install kaldr

If you have chosen local installation, check your PATH environment variable. npm creates symlinks to all binaries in ~/node_modules/.bin hidden folder. So you may want to prepend it to PATH.

Server setup

# Log to console
# Log to file
kaldr >> client.log &
# Test kaldr
curl -b 'message=Hello, World!' localhost:8080/kaldr.log

Client setup

Load kaldr

<iframe id="logger" src="http://localhost:8080/kaldr.frame#" style="display:none"></iframe>

Send message to kaldr

var logger = document.getElementById('logger'),
    src = logger.getAttribute('src').split('#')[0];
window.onerror = function (mesage, file, line) {
    logger.setAttribute('src', src + '#' + message + ' in ' + file + ' at line ' + line);
