Microsoft Application Insights JavaScript SDK - React Plugin

React Plugin for the Application Insights Javascript SDK, enables the following:

• Tracking of router changes
• React components usage statistics

Full documentation for the React Plugin for the Application Insights JavaScript SDK can be found on Microsoft Docs.

Getting Started

Install npm package:

npm install @microsoft/applicationinsights-react-js

Basic Usage

import React from 'react';
import { ApplicationInsights } from '@microsoft/applicationinsights-web';
import { ReactPlugin, withAITracking } from '@microsoft/applicationinsights-react-js';
import { createBrowserHistory } from "history";

const browserHistory = createBrowserHistory({ basename: '' });
var reactPlugin = new ReactPlugin();
var appInsights = new ApplicationInsights({
    config: {
        connectionString: 'YOUR_CONNECTION_STRING_GOES_HERE',
        extensions: [reactPlugin],
        extensionConfig: {
          [reactPlugin.identifier]: { history: browserHistory }
        }
    }
});
appInsights.loadAppInsights();

// To instrument various React components usage tracking, apply the `withAITracking` higher-order
// component function.

class MyComponent extends React.Component {
    ...
}

export default withAITracking(reactPlugin, MyComponent);

For react-router v6 or other scenarios where router history is not exposed, appInsights config enableAutoRouteTracking can be used to auto track router changes.

var reactPlugin = new ReactPlugin();
var appInsights = new ApplicationInsights({
    config: {
        connectionString: 'YOUR_CONNECTION_STRING_GOES_HERE',
        enableAutoRouteTracking: true,
        extensions: [reactPlugin]
        }
    }
});
appInsights.loadAppInsights();

Configuration

React components usage tracking

To instrument various React components usage tracking, apply the withAITracking higher-order component function.

It will measure time from the ComponentDidMount event through the ComponentWillUnmount event. However, in order to make this more accurate, it will subtract the time in which the user was idle. In other words, React Component Engaged Time = ComponentWillUnmount timestamp - ComponentDidMount timestamp - idle time.

To see this metric in the Azure portal you need to navigate to the Application Insights resource, select "Metrics" tab and configure the empty charts to display Custom metric named "React Component Engaged Time (seconds)", select aggregation (sum, avg, etc.) of your liking and apply split by "Component Name".

You can also run custom queries to slice and dice AI data to generate reports and visualizations as per your requirements. In the Azure portal, navigate to the Application Insights resource, select "Analytics" from the top menu of the Overview tab and run your query.

Please note that it can take up to 10 minutes for new custom metric to appear in the Azure Portal.

Sample App

Azure-Samples/application-insights-react-demo.

Example of Measuring Page Duration in an SPA

Measuring the duration for a Single Page Application (SPA) can be challenging when the URL does not change. Therefore, we recommend using startTrackPage and stopTrackPage for accurate duration calculation.

You can find an example in our sample app. After running the app, visit http://localhost:3000/test to see it in action.

React Router

Compatibility Matrix

As part of updating to support ApplicationInsights 3.x we will be bumping the major version number of this extension to match the major version of the supported React-JS version (which will be v17.x for the first release).

Additionally, as part of this change the existing v3.x extension has been moved into the release3.x branch

:bulb: Note If you have encounter error as this:

Type 'ReactPlugin' is not assignable to type 'ITelemetryPlugin'.

Nightly Builds

To aid with testing and validation we also produce and publish nightly builds whenever there is a change from the previous build. These builds are published to the NpmJs registry on a successful build / test pass.

This process also tags the source code so that we can track the specific changes included using a nightly build specific version number which is the format "nightly-yymm-##" eg. nightly-2208-05

These nightly builds will not be retained indefinitely and should only be used for pre-production testing and/or validation of any changes that have not yet been released.

NPM

The NPM builds are tagged as "nightly" and can by downloaded using this as the version number npm install @microsoft/applicationinsights-react-js@nightly or using the nightly specific version number which is "nightly.yyyymm-###" (npm install @microsoft/applicationinsights-react-js@2.7.3-nightly.2112-08) where ## is the specific build number for the month (Note, slightly different version from the source code tag due to compatibility issues between the different systems).

Deployment process

When a new release is deployed the following occurs as part of the release

• NPM packages are created and published to NpmJs
