Remote JavaScript Console.Re Connector script for advanced logging, debugging and testing

Send log, debug or test information from any webpage, web application or node.js server to remote logger. View output results on any device: tablet, phone or desktop in a separate browser window at http://console.re/project-channel-name.

Connector script extends console object adding new methods for sending messages to remote logger with:

console.re.log(); console.re.info(); console.re.debug(); console.re.warn(); console.re.error(); console.re.count(); console.re.test(); console.re.assert(); console.re.time(); console.re.timeEnd(); console.re.trace(); console.re.clear();

Moreover, while using in browsers, you can log information about DOM elements, CSS properties, track Media Queries and Window size changes with:

console.re.size(); console.re.css(); console.re.media();

Remote JavaScript Console simplifies front-end (in browsers) and backend (in node.js) web development and testing. No plugins, no browser extensions requred, pure JavaScript.

Console.Re connector (client) script works in all major browsers (desktop or mobile) and node.js servers running on Linux, Mac, and Windows.

Note: This is a client script, not a server. With this code, you can connect and send messages to any project-channel-name you want on our public http://console.re server, you can see your logs at http://console.re/project-channel-name. If you need your own private server with support or API customization, please read this section and contact us.

Warning: Use Console.Re for development and testing environments only. DO NOT USE IT ON PRODUCTION WEBSITES AND SERVERS.

Installation and Use

Node.Js

1) Install module using npm as follows:

$ npm install console-remote-client

2) In your node apps.js, use require to include module and connect to remote server:

var consolere = require('console-remote-client').connect('console.re','80','YOUR-CHANNEL-NAME');

3) [required] change connect function argument YOUR-CHANNEL-NAME to your own your-project-channel-name (any string)

4) add in your code: console.re.log('remote log test');

5) open remote logger in a separate browser: http://console.re/your-project-channel-name

6) restart your app.js, and you should see in logger the following: [log] remote log test

Browser

1) open your template header or main HTML file and include connector.js FIRST thing in <head> tag or BEFORE any other script tags:

<script src="//console.re/connector.js" data-channel="YOUR-CHANNEL-NAME" id="consolerescript"></script>

2) [required] change YOUR-CHANNEL-NAME in attribute data-channel to your-project-channel-name (any string)

3) add in your JavaScript code: console.re.log('remote log test');

4) open remote logger in a separate browser: http://console.re/your-project-channel-name

5) reload your webpage or app, you should see in logger the following: [log] remote log test

Below is an example how to include connector.js in <head>:

<!DOCTYPE html>
  <html>
    <head>
      <script src="//console.re/connector.js" data-channel="my-website-channel" id="consolerescript"></script>
      <script src="/js/lib/jquery.js"></script>
      <script src="/js/your-script1.js"></script>
      <script src="/js/your-script2.js"></script>
    </head>
    ...

Install with inline javascript code. (in case you don't have access to head)

1) include this code JavaScript BEFORE your code :

var consolere = {
  channel:'YOUR-CHANNEL-NAME',
  api:'//console.re/connector.js',
  ready: function(c) {var d=document,s=d.createElement('script'),l;s.src=this.api;s.id='consolerescript';s.onreadystatechange=s.onload=function(){if(!l){c();}l=true;};d.getElementsByTagName('head')[0].appendChild(s);}
};

2) [required] change YOUR-CHANNEL-NAME in key channel to your-project-channel-name (any string)

3) after this, in your JavaScript code, use consolere.ready() callback to wrap console.re API:

consolere.ready(function() {
  console.re.log('remote log test');
});

4) open logger in a separate browser: http://console.re/your-project-channel-name

5) reload your webpage or app, you should see in logger the following: [log] remote log test

API

console.re.log()

Sends LOG level message with object, array, string, number, DOM Element to the remote console.

console.re.log(object|array|selector|'string %s',string|'string %d',number[,object, ...]);

Interpolation allows to insert the value of next argument inside previous string with %s or %d. See usage examples.

console.re.info()

Sends INFO level message to remote console with optional arguments same as console.re.log().

console.re.info(message);

console.re.warn()

Sends WARN level message to remote console with optional arguments same as console.re.log().

console.re.warn(message);

console.re.debug()

Sends DEBUG level message to remote console with optional arguments same as console.re.log().

console.re.debug(message);

console.re.error()

Sends ERROR level message to remote console with optional arguments same as console.re.log().

console.re.error(message);

console.re.size()

Displays size of DOM element(s), width and height for given selector(s) or displays current Window size if called with no arguments. Use any jQuery selectors if jQuery library included in project. This is browser only API.

console.re.size([selector],[,selector,...]);

console.re.css()

Displays value of specified CSS properties in array for given selector(s). Use any jQuery selectors if jQuery library included in project. This is browser only API.

console.re.css(selector,['property','property2', ... 'propertyN']);

console.re.media(['all']);

console.re.time()

Creates a new timer under the given label. To stop timer and display time result, call console.re.timeEnd(label); with the same label.

console.re.time(label);

console.re.timeEnd()

Stops timer and displays time result started before with given label.

console.re.timeEnd(label);

console.re.count()

Displays the number of times count call with given label was executed.

console.re.count(label);

console.re.test()
