CONSOLE REMOTE VER. 2 RELEASED WITH PRIVATE SERVER SUPPORT

Console Remote Server is available here: https://github.com/kurdin/console-remote-server

Try all Console Remote examples at RunJS.co https://runjs.co/s/g7LRa7LU1

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

Send log, debug or test information from any webpage, web mobile app 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.type(); console.re.assert(); console.re.time(); console.re.timeEnd(); console.re.now(); console.re.trace(); console.re.clear(); console.re.mark();

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 required, 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 please look at this: https://github.com/kurdin/console-remote-server

Warning: Use Console.Re for development and testing environments only. IT WONT WORK ON PRODUCTION WEBSITES AND SERVERS.

What's New in Version 2

Console API has new methods

console.re.now(label) - returns the relative distance between two time points, measured in milliseconds

console.re.type() - returns the type of a variable or property

console.re.mark([label]) - action to mark current log position in console output with optional label

Console connector has a new options

redirectDefaultConsoleToRemote (:boolean) - if true, default calls to console.[log|warn|error|debug] methods will be redirected to remote console log calls

disableDefaultConsoleOutput (:boolean) - if true, default console log output will be removed for all remote console log calls

server (:string) - remote console server url, to connect and output remote logs to your own, remote console server, default is http://console.re

Console API shortcuts

relog() shortcut for console.re.log()

instead of using console.re.log('test'), now you can use a shortcut relog('test');

re.[api]() shortcut for console.re.[api]()

instead of using console.re.log('test'), now you can use a shortcut re.log('test'); or console.re.test('test') has shortcuts re.test('test');

console.re.[api] shortcuts

instead of using console.re.log('test'), now you can use a shortcut console.re.l('test') or re.l('test');

Full list of API shortcuts

Installation and Use

Node.Js

  1. Install module using npm as follows:
npm install console-remote-client
  1. In your node.js app, use require to include module and connect to remote server:
const consolere = require('console-remote-client').connect({
  server: 'https://console.re', // optional, default: https://console.re
  channel: 'YOUR-CHANNEL-NAME' // required
});

in case your server supports import, use

import consolere from 'console-remote-client'

consolere.connect({
  server: 'https://console.re', // optional, default: https://console.re
  channel: 'YOUR-CHANNEL-NAME',
})
  1. [required] change connect function argument YOUR-CHANNEL-NAME to your own your-project-channel-name (any string)

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

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

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

Browser

Install with import. (recommended)

  1. install console-remote-client module
npm install console-remote-client
  1. import once into your javascript file. (in your app root index.js file)
import consolere from 'console-remote-client'
  1. connect with options for your server and channel
consolere.connect({
  server: 'https://console.re', // optional, default: https://console.re
  channel: 'YOUR-CHANNEL-NAME', // required
  redirectDefaultConsoleToRemote: true, // optional, default: false
  disableDefaultConsoleOutput: true, // optional, default: false
});

or use can use require

const consolere = require('console-remote-client').connect({
  server: 'https://console.re', // optional, default: https://console.re
  channel: 'YOUR-CHANNEL-NAME' // required
});
  1. [required] change YOUR-CHANNEL-NAME in attribute data-channel to your-project-channel-name (any string)

  2. in your JavaScript code: console.re.log('remote log test'); or console.log('remote log test'); if redirectDefaultConsoleToRemote is true.

Install with single <script> tag.

  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-server="OPTIONAL-PRIVATE-SERVER-URL"
  data-channel="YOUR-CHANNEL-NAME"
  id="consolerescript"
></script>
  1. [required] change YOUR-CHANNEL-NAME in attribute data-channel to your-project-channel-name (any string)

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

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

  4. 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-server="https://console.re"
      data-options="redirectDefaultConsoleToRemote[optional], disableDefaultConsoleOutput[optional]"
      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>
  ...
</html>

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',
  server: 'https://console.re' // optional
  options='redirectDefaultConsoleToRemote,disableDefaultConsoleOutput' // optional
  ready: function (c) {
    var d = document,
      s = d.createElement('script'),
      l
    s.src = this.api
    s.id = 'consolerescript'
    s.setAttribute('data-channel', this.channel)
    if (this.options) {
      s.setAttribute('data-options', this.options)
    }
    if (this.server) {
      s.setAttribute('data-server', this.server)
    }
    s.onreadystatechange = s.onload = function () {
      if (!l) {
        c()
      }
      l = true
    }
    d.getElementsByTagName('head')[0].appendChild(s)
  }
}
  1. [required] change YOUR-CHANNEL-NAME in key channel to your-project-channel-name (any string)

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

consolere.ready(function () {
  console.re.log('remote log test')
})
  1. open logger in a separate browser: http://console.re/your-project-channel-name

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

Public and Private Servers

For moderate use, you can connect and see your logging information on our public server at http://console.re for FREE. No registration required. Just install connector script and use any string as your channel name.

All information sent to the public server will be open for anyone who knows your channel name.

If you need a private and more secure solution, you can download and install your own, private console remote personal server.

https://github.com/kurdin/console-remote-server

Just install server and use standard connector's option server to connector with your private server.

All information sent to the private server will be more secured and no one can see it.

TypeScript Support

We have TypeScript definitions in file ./index.d.ts, this should be automaticly located by TypeScript configuration if your project has TypeScript.

In some cases, global console remote variables relog or re.[method] are not detected correctly by TypeScript and Eslint can start complaining about.

To fix that problem just add those lines to your local project.d.ts file:

declare var relog: (...message: any) => void
declare var re: {
  [key in any]: (...message: any) => void
}
