# (DEPRECATED) Microsoft Application Insights JavaScript SDK

Note: This package has been moved to @microsoft/applicationinsights-web. Please install that package instead to get the latest updates and changes to Application Insights.

Application Insights tells you about your app's performance and usage. By adding a few lines of code to your web pages, you get data about how many users you have, which pages are most popular, how fast pages load, whether they throw exceptions, and more. And you can add code to track more detailed user activity.

Get started

To use this SDK, you'll need a subscription to Microsoft Azure. Application Insights has a free subscription option. In the Azure Preview Portal, create new or open an existing Application Insights resource.

Full documentation for beta version of next SDK release is here . Please try it out and provide feedback/log any issues.

Initializing Application Insights JS SDK script

There are several ways to initialize Application Insights.

| | Dynamic loading. JS script tag is inserted in the head of the page. This is the recommended approach as our CDN is getting frequent updates. | Static loading. You are responsible for including JS script tag or bundling the script with your other scripts. | |------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------| | Using initialization snippet | Dynamic loading with snippet This is default approach used in a new ASP.NET application created in Visual Studio. Use this for MVC applications. | Host AI JS SDK and initialize statically. Cordova applications where you would like to embed scripts into your application for faster loading is an example of when you would use this approach. | | Using module import | Dynamic loading using module import. This is the recommended approach for modern modular applications. | TBD |

Use JS snippet and initialize dynamically (download full Application Insights script from CDN)

Use this method for an MVC application. Get "code to monitor my web pages" from the Quick Start page, and insert it in the head of your web pages. Application Insights script will be downloaded from CDN or you can override the script hosting location by specifying url parameter in the config.

<script type="text/javascript">
    var appInsights=window.appInsights||function(a){
        function b(a){c[a]=function(){var b=arguments;c.queue.push(function(){c[a].apply(c,b)})}}var c={config:a},d=document,e=window;setTimeout(function(){var b=d.createElement("script");b.src=a.url||"https://az416426.vo.msecnd.net/scripts/a/ai.0.js",d.getElementsByTagName("script")[0].parentNode.appendChild(b)});try{c.cookie=d.cookie}catch(a){}c.queue=[];for(var f=["Event","Exception","Metric","PageView","Trace","Dependency"];f.length;)b("track"+f.pop());if(b("setAuthenticatedUserContext"),b("clearAuthenticatedUserContext"),b("startTrackEvent"),b("stopTrackEvent"),b("startTrackPage"),b("stopTrackPage"),b("flush"),!a.disableExceptionTracking){f="onerror",b("_"+f);var g=e[f];e[f]=function(a,b,d,e,h){var i=g&&g(a,b,d,e,h);return!0!==i&&c["_"+f](a,b,d,e,h),i}}return c
    }({
        instrumentationKey: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx"
    });

    window.appInsights=appInsights,appInsights.queue&&0===appInsights.queue.length&&appInsights.trackPageView();
</script>

Learn more.

Import as a module and initialize dynamically (download full Application Insights script from CDN)

Use this method for a modern JS application that is using modules. Just like in snippet scenario the full script will be downloaded from CDN.

• Obtain instrumentation key from your Application Insights resource

• Install applicationinsights-js with npm npm install applicationinsights-js

• Import and call downloadAndSetup to initialize it. You can override the script hosting location by specifying url parameter in the config ` /* import AppInsights */ import {AppInsights} from "applicationinsights-js"

/* Call downloadAndSetup to download full ApplicationInsights script from CDN and initialize it with instrumentation key */ AppInsights.downloadAndSetup({ instrumentationKey: "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx" });

/* example: track page view / AppInsights.trackPageView( "FirstPage", / (optional) page name / null, / (optional) page url if available / { prop1: "prop1", prop2: "prop2" }, / (optional) dimension dictionary / { measurement1: 1 }, / (optional) metric dictionary / 123 / page view duration in milliseconds */ );

/* example: track event */ AppInsights.trackEvent("TestEvent", { prop1: "prop1", prop2: "prop2" }, { measurement1: 1 });

### Include AI JS SDK script and initialize statically
Use this approach if you would like to host AI JS SDK script on your endpoint or bundle it with other scripts. One popular example is Cordova applications (see [this blog post](http://www.teamfoundation.co.za/2016/02/application-insights-and-typescript/). After JS script has loaded, include the following snippet to initialize Application Insights:

`

API reference

Data on users, page views, and exceptions are provided out of the box. You can write your own code to track specific events and metrics.

See:

• JavaScript API reference
• API overview with portal examples

• Check out our Wiki and FAQ for other useful info.
• Follow latest Application Insights changes and announcements on ApplicationInsights Announcements
• Application Insights Home. The main repository for documentation of overall SDK offerings for all platforms.
• SDK Release Schedule

Build and run check-in tests:

• Build

  • npm install -g grunt-cli
  • npm install
  • grunt or Ctrl+Shift+B in VisualStudio Code
  • grunt module to build the npm module
  • compiled files are dropped into a /bundle folder

• Run check-in tests

  • grunt test to build and run tests
  • You can also open JavaScriptSDK.Tests/Selenium/Tests.html directly in your browser to debug failing tests.

To debug tests in PhantomJS use a remote debugger: phantomjs.exe --remote-debugger-port=9000 \JavaScript\JavaScriptSDK.Tests\phantomJS.debug.js. If webkit console isn't working execute the following script in a browser's console: function isEnterKey(event) { return (event.keyCode !== 229 && event.keyIdentifier === "Enter") || event.keyCode === 13; }.

Releases

Note: ES3/IE8 compatibility will be removed in the future v3.x.x releases (scheduled for mid-late 2022), so if you need to retain ES3 compatibility you will need to remain on the 2.x.x versions of the SDK or your runtime will need install polyfill's to your ES3 environment before loading / initializing the SDK.

Potential Breaking Change

• fetch Ajax tracking was also been change to be on by default from this version moving forward, if you are running in an environment without fetch support and you are using an incompatible polyfill (that doesn't identify itself as a polyfill) or the SDK you start seeing recursive or duplicate (fetch and XHR requests) being reported you WILL need to add disableFetchTracking with a value of true to your configuration to disable this functionality.
• TypeScript 4.x required for some typings from the core EnumHelperFuncs.d.ts (Fixed in v2.8.1)

Significant changes

This release adds support for the SDK to

• TelemetryInitializers have been moved to BaseCore so they are now available as part of all Sku's and not just those using the analytics plugin (@microsoft/applicationinsights-analytics-js) using the appInsights.addTelemetryInitializer(...)
• Web Events (addEventHandler) now support "event namespaces" (similar to jQuery) to enable the removing of events by just specifying the namespace and new specific eventOn(...) and eventOff(...) API's.
• Fully unload, removing all internal event handlers (may be re-initialized) via the appInsights.unload(...) function.
• Dynamically add a plugin to an already initialized SDK (optionally replacing an existing) via new appInsights.addPlugin(...) function
• New helper to get any plugin from an initialized SDK via appInsights.getPlugin("...identifier...")
• Dynamically remove a plugin via the appInsights.getPlugin("...identifier..").remove()
• Enable / Disable any plugin (even if the plugin doesn't support disabling itself) via appInsights.getPlugin("...identifier...").setEnabled(true/false)
• The standard name fro the analytics plugin @microsoft/applicationinsights-analytics-js has been renamed and is now exported as AnalyticsPlugin, for backward compatibility it is also exported as it's previous name ApplicationInsights, if you are using it directly it is recommended that you update to use the new exported name.

While this release contains a substantial amount of additional functionality and code, there has also been significant minification efforts (which also drove some of the SDK naming) to keep the minified code around the same size. We intend to keep working on additional improvements to attempt to bring the size changes down further. However, the minification improvements do generally cause a lower level of GZip compression most because of the removal of duplicate names. The main readme for the AISKU has a table of the CDN base SKU sizes, as the CDN version includes all public API's (older versions for backward compatibility and newer smaller versions) when using NPM you should see smaller sizes than those shown.

Note: Due to the above changes required to support the above, there may be some minor TypeScript Type compatibility warnings when you attempt to use components from v2.8.0 with older SDK's (forward compatibility), backward compatibility, using Core v2.8.0 with older components is supported and v2.8.0 is completely backward compatible. This is due to some API's now support both older (for back compat) and new enhanced arguments, we have attempted to keep these changes to a minimum. If you are getting typing errors such as "Argument of type 'XXXXX' os not assignable to parameter of type 'YYYY'", please ensure that you are using all v2.8.0 components and raise an issue if this does not resolve you issue. As a work around casting to work around this warning should not cause any issues.

Due the the size of this change, the above date is the NPM release date and CDN deployment will be over an extended period.

XHR/Fetch enhancement

Adds additional performance data derived from the window.performance.getEntries() for the fetch or XHR request.

Configuration options | Name | Default | Description | |------|---------|-------------| | enableAjaxPerfTracking | false | Default false. Flag to enable looking up and including additional browser window.performance timings in the reported ajax (XHR and fetch) reported metrics. | maxAjaxPerfLookupAttempts | 3 | Defaults to 3. The maximum number of times to look for the window.performance timings (if available), this is required as not all browsers populate the window.performance before reporting the end of the XHR request and for fetch requests this is added after its complete. | ajaxPerfLookupDelay | 25 | Defaults to 25ms. The amount of time to wait before re-attempting to find the windows.performance timings for an ajax request, time is in milliseconds and is passed directly to setTimeout().

Auto track exception React Native Plugin

This has been enabled by default in the updated version. It can be disabled by adding the disableExceptionCollection config value with a value of true.

ES3 Support

With this release the source files can be loaded in an ES3 environment (IE7/8) and send requests to the server.

Enable support for reusing plugins in multiple instances of AppInsights #1132

We have added upport to enable reusing the same plugin in different instances of AppInsights, owned by the same application (but using different Instrumentation keys) is required so that they can reuse a single Plugin instance for all instances.

This changes introduces a new IProcessTelemetryContext interface that is passed to the processTelemetry() method so that the plugins can use the current request context for the event rather than the context during initialization.

To assist with creating plugins we have also introduced a base class that you can use for creating new plugins BaseTelemetryPlugin, details are included on the Readme

You can set enableAutoRouteTracking: true to enable state based route tracking for your Single Page Application (React, Angular, Vue, etc). You do not need to install a separate plugin to use this configuration option.

This setting will cause a new Page View telemetry item to be sent each time your app's route changes (including Hash route changes).

v 2.0.1

trackException Change

This update has a couple of non-breaking API changes. Namely, trackException is now consistent with the Node.js SDK. The only change here is the named argument is renamed from error to exception. A shim is in place so any existing usages of trackException will still work, and the old field is marked as optional, so any type-checked files will still "compile". There are no breaking changes with this change, but you are encouraged to use exception as your named argument field as error will be deprecated in a future major version.

Old

appInsights.trackException({ error: new Error() });

New

appInsights.trackException({ exception: new Error() });

Correlation Header Domain Whitelisting #869

Second, the ability to only send correlation headers to specific, whitelisted domains is now available as a configuration option , correlationHeaderDomains. It accepts an array of domain strings. Wildcards ("") are okay. By populating this array, all other domains which your application makes requests to will *not** have correlation headers included. This setting makes it easy to avoid OPTIONS requests to services outside of your control.

You can use the inclusion list and the exclusion list in conjunction with each other to add correlation headers to a particular domain, example.com, and at the same time exclude headers from a prefixed version of it, no-headers.example.com.

Tag Override Change #903

Performing custom tag overrides is now more consistent with all of the other Application Insights SDKs, in that it is modified via a simple key-value dictionary. There are no breaking changes with this update, and if you are setting any tags via the old way, they will still work as they do now. You are encouraged to update them since the old way will be deprecated in a future major version release.

Old

var telemetryInitializer = (item) => {
  item.tags.push({ "ai.cloud.role": "My Web App" });
};
appInsights.addTelemetryInitializer(telemetryInitializer);

New

var telemetryInitializer = (item) => {
  item.tags["ai.cloud.role"] = "My Web App";
};
appInsights.addTelemetryInitializer(telemetryInitializer);
