Exceptionless JavaScript/Node client

We are working towards a 1.0 and would love your help! Please note that we may break the api from build to build until we reach a 1.0. Please feel free to create an issue or send us a pull request.

Using Exceptionless

Installing

Please follow the instructions below for installing the exceptionless JavaScript client.

JavaScript

Use one of the below methods to install exceptionless into your web app.

Bower

Install the package by running bower install exceptionless or skip this step and use the scripts hosted on our CDN.
Add the script to your html page. We recommend placing this as the very first script.

<script type="application/javascript" src="bower_components/exceptionless/dist/exceptionless.min.js"></script>

CDN

We will be adding cdn support in the near future.

Node.js

Use this method to install exceptionless into your node app.

Install the package by running npm install exceptionless --save-dev.
Add the exceptionless client to your app:

var client = require('exceptionless').ExceptionlessClient.default;

Configuring the client.

You can configure the exceptionless client a few different ways. The section below will cover the different ways you can configure the ExceptionlessClient. NOTE: The only required setting that you need to configure is the clients apiKey.

JavaScript

You can configure the apiKey or serverUrl as part of the script tag. This will be applied to all new instances of the ExceptionlessClient

<script type="application/javascript" src="bower_components/exceptionless/dist/exceptionless.min.js?apiKey=API_KEY_HERE"></script>

You can set the apiKey or serverUrl on the default ExceptionlessClient instance.

var client = exceptionless.ExceptionlessClient.default;
client.config.apiKey = 'API_KEY_HERE';
client.config.serverUrl = 'http://localhost:50000';

You can create a new instance of the ExceptionlessClient and specify the apiKey, serverUrl or configuration object.

var client = new exceptionless.ExceptionlessClient('API_KEY_HERE');
// or with a api key and server url.
var client = new exceptionless.ExceptionlessClient('API_KEY_HERE', 'http://localhost:50000');
// or with a configuration object
var client = new exceptionless.ExceptionlessClient({
  apiKey: 'API_KEY_HERE',
  serverUrl: 'http://localhost:50000',
  submissionBatchSize: 100
});

Node.js

You can set the apiKey or serverUrl on the default ExceptionlessClient instance.

var client = require('exceptionless').ExceptionlessClient.default;
client.config.apiKey = 'API_KEY_HERE';
client.config.serverUrl = 'http://localhost:50000';

You can create a new instance of the ExceptionlessClient and specify the apiKey, serverUrl or configuration object.

var exceptionless = require('exceptionless');

var client = new exceptionless.ExceptionlessClient('API_KEY_HERE');
// or with a api key and server url.
var client = new exceptionless.ExceptionlessClient('API_KEY_HERE', 'http://localhost:50000');
// or with a configuration object
var client = new exceptionless.ExceptionlessClient({
  apiKey: 'API_KEY_HERE',
  serverUrl: 'http://localhost:50000',
  submissionBatchSize: 100
});

Sending Events

Once configured, Exceptionless will automatically send any unhandled exceptions that happen in your application. The sections below will show you how to send us different event types as well as customize the data that is sent in.

####Sending Events

You may also want to send us log messages, feature usages or other kinds of events. You can do this very easily with our fluent api.

// javascript
var client = exceptionless.ExceptionlessClient.default;
// Node.Js
// var client = require('exceptionless').ExceptionlessClient.default;

client.submitLog('Logging made easy');

// You can also specify the log source and log level.
// We recommend specifying one of the following log levels: Trace, Debug, Info, Warn, Error
client.submitLog('app.logger', 'This is so easy', 'Info');
client.createLog('app.logger', 'This is so easy', 'Info').addTags('Exceptionless').submit();

// Submit feature usages
client.submitFeatureUsage('MyFeature');
client.createFeatureUsage('MyFeature').addTags('Exceptionless').submit();

// Submit a 404
client.submitNotFound('/somepage');
client.createNotFound('/somepage').addTags('Exceptionless').submit();

// Submit a custom event type
client.submitEvent({ message = 'Low Fuel', type = 'racecar', source = 'Fuel System' });

####Manually Sending Errors

In addition to automatically sending all unhandled exceptions, you may want to manually send exceptions to the service. You can do so by using code like this:

// javascript
var client = exceptionless.ExceptionlessClient.default;
// Node.Js
// var client = require('exceptionless').ExceptionlessClient.default;

try {
  throw new Error('test');
} catch (error) {
  client.submitException(error);
}

####Sending Additional Information

You can easily include additional information in your error reports using our fluent event builder API.

// javascript
var client = exceptionless.ExceptionlessClient.default;
// Node.Js
// var client = require('exceptionless').ExceptionlessClient.default;

try {
  throw new Error('Unable to create order from quote.');
} catch (error) {
  client.createException(error)
    // Set the reference id of the event so we can search for it later (reference:id).
    // This will automatically be populated if you call client.config.useReferenceIds();
    .setReferenceId('random guid')
    // Add the order object (the ability to exclude specific fields will be coming in a future version).
    .setProperty("Order", order)
    // Set the quote number.
    .setProperty("Quote", 123)
    // Add an order tag.
    .addTags("Order")
    // Mark critical.
    .markAsCritical()
    // Set the coordinates of the end user.
    .setGeo(43.595089, -88.444602)
    // Set the user id that is in our system and provide a friendly name.
    .setUserIdentity(user.Id, user.FullName)
    // Submit the event.
    .submit();
}
