Webpack

If you are using webpack you might need change config to load package properly.

Alternative 1 (Recommended)

Use webpack-modules plugin

npm i --save-dev webpack-modules

// Add this to your webpack config file
const WebpackModules = require('webpack-modules');
 
module.exports = {
  // ...
  plugins: [
    new WebpackModules()
  ]
}

Alternative 2

Change mainFields setting (may cause issues with other dependencies)

module.exports = {
  //...
  resolve: {
    mainFields: ['module', 'main']
  }
};

Examples

Sample code:

import { ApplicationInsights, RequestData, ApplicationInsightsConnection } from 'applicationinsights-cloudflareworkers'

const requestTest = new RequestData({
    name: 'Test',
    success: true,
    url: 'https://example.com',
    id: '15fadc35-65b2-41da-b86f-998dcb7489e3',
    properties: {
        anyName: 'anyValue',
    },
    duration: '00.00:00:10.000000',
    responseCode: '200',
})

const ai = new ApplicationInsights({
    context: {
        'ai.operation.id': 'testid',
    },
    connection: ApplicationInsightsConnection.fromConnectionString('InstrumentationKey=yourinstrumentationkey;'),
})

// Pass in AvailabilityData, EventData, ExceptionData, MessageData, MetricData, PageViewPerfData, RemoteDependencyData or RequestData
ai.trackData(requestTest, 'RequestData') // type (second) argument might be required if you minify your code(unminified it can be inferred)

const res = await ai.flush() // Flush is not automatic. You need to call .flush()

// After flush it takes ~5 mins before you will see in application insights

console.log(`Status: ${res.status}`) // See response for errors if code is not 200
