Prerequisites

Node.js and NPM
A free port

Installation

$ git clone git://github.com/Lapple/ErrorBoard.git
$ cd ErrorBoard
$ npm install

Configuration

Edit the config section of package.json:

// ...
"config": {
    "dbfile": "db", // path to database file
    "port": 3000    // web application port
},
// ...

Running

After you have everything installed and configured, run:

npm start

Once the app has started successfully, navigate to localhost at specified port (e.g. http://127.0.0.1:3000/) to get the error data. Similar error messages are not grouped, however the one can navigate to Scripts tab to get the idea which file:line pairs produce most errors.

Browser snippet

The first time you visited http://127.0.0.1:3000/ you probably won't see any errors since they were not being sent to the board. To start sending errors, make sure that the following JavaScript snippet is the first code, executed on your pages:

// JavaScript
window.onerror = function( message, url, line, column, error ) {
  var e = encodeURIComponent;
  ( new Image() ).src = 'http://127.0.0.1:3000/error?message=' + e( message ) +
                                                   '&url='     + e( url ) +
                                                   '&line='    + e( line ) +
                          ( error && error.stack ? '&stack='   + e( error.stack ) : '' ) +
                                        ( column ? '&column='  + e( column ) : '' );
};

Replace 127.0.0.1:3000 with the address and the port number your ErrorBoard is running.

Metadata

The error reporting snippet might optionally pass a meta= parameter that can either be a plain or JSON string. Use this parameter if you need to pass other contextual information about the page or user, for example, locale, environment or build number.
