Logit.io JavaScript Plugin

This JavaScript Plugin provides websites with an interface to send debug information to a Logit.io endpoint.

Contents

Installing

Logit.io can be installed with bower

bower install --save logitio

or pulled from our cdn

<script src="https://resources.logit.io/logit.js"></script>

Using the plugin

Once the plugin is installed, you do not need to reference any JavaScript, the plugin script will add the window.logit object to your window object automatically.

You can then refer to the plugin from anywhere in your code as simply logit or window.logit.

Initialization

Before you can use the plugin, you need to initialize it by passing it some setup options by calling the the init() function. The first parameter is required and the second is a bunch of options:

window.logit.init( apiKey, options );

init() parameters

  • String apiKey - (required) your Logit.io API Key, which grants you app access to the endpoint.
  • Object options - (optional) parameters with the following key names:
    • Object defaultDimensions - JSON object describing default dimensions to send with every message. For example, device/OS details, app version details, user details, etc.
    • Boolean logToConsole - if true, messages will be logged using window.console methods. Defaults to false.
    • Integer verbosity - a value corresponding to an entry in this.LOG_PRIORITIES which filters log messages if the priority value is greater than the verbosity value. Defaults to this.LOG_PRIORITIES.VERBOSE.
    • Integer sendInterval - Interval in ms at which to send queued messages. Defaults to 200ms.
    • Boolean disableSending - if true, sending of messages to remote Logit endpoint is disabled and messages are not added to send queue. This is useful for development phases when it's useful to use the plugin to log to the console but not to the remote endpoint. Defaults to false.

Logging messages

The plugin provides the following logging functions, in order of decreasing priority:

  • logit.emergency( message, dimension );
  • logit.error( message, dimension );
  • logit.warn( message, dimension );
  • logit.info( message, dimension );
  • logit.log( message, dimension );
  • logit.debug( message, dimension );
  • logit.trace( message, dimension );
  • logit.verbose( message, dimension );

Parameters

  • String message - (required) the message to send
  • Object dimensions - (optional) a list of custom dimensions in key/value form

Additional functions

The plugin exposes the following additional functions:

  • logit.pauseSending(); Pauses sending of queued messages. Useful to conserve bandwith if you website is doing a bandwith-heavy operation. Note: if the number of queued messages reaches the configured maxQueueSize while sending is paused, each time a new message is added to the queue, the first message will be lost.
  • logit.resumeSending(); Resumes sending of queued messages.
  • logit.setVerbosity( verbosity ); Sets the current verbosity for logit messages.
    • Mixed verbosity - new verbosity value to set, either as an integer value of 0 to 7, of as the string name of the corresponding priority (case-insensitive), e.g. "error"
  • logit.getVerbosity(); Returns the current verbosity for logit messages.
  • logit.getPriorityName( priority ); Returns the string name of a log priority given the priority value. Returns null if a matching name is not found.
    • Integer priority - numerical priority value to find name for.
