clean-console v0.4.0

clean-console

Quickly loads a remote page using phantomjs to check if there are any JavaScript console errors.

Install and use

npm install -g clean-console
// assumes phantomjs is installed
clean-console -i <url>

Note: only actual exceptions will be logged, failed console.assert statements DO NOT cause a true browser error (unlike nodejs).

A good pattern to unify nodejs/browser assertion handling is to wrap assertions into helper method:

function really(condition, message) {
    console.assert(condition, message); // stops nodejs execution
    if (!condition) {
        // stop execution in a browser
        throw new Error(condition.toString() + ' failed, ' + message);
    }
}

Update

Seems the latest PhantomJs 2 generates errors when using console.error and console.assert by default.
