Add ApplicationInsights SDK + +```bash +# Install ApplicationInsights +npm install @microsoft/applicationinsights-web +``` + +### 3. Configure ApplicationInsights in Angular + +Update `app.component.ts` to initialize ApplicationInsights: + +```typescript +import { Component, OnInit } from '@angular/core'; +import { ApplicationInsights } from '@microsoft/applicationinsights-web'; + +@Component({ + selector: 'app-root', + templateUrl: './app.component.html', + styleUrls: ['./app.component.css'] +}) +export class AppComponent implements OnInit { + private _appInsights: ApplicationInsights; + + constructor() { + // This initialization alone will cause the issues + this._appInsights = new ApplicationInsights({ + config: { + connectionString: 'PLACEHOLDER_CONNECTION_STRING', + enableAutoRouteTracking: true, + enableCorsCorrelation: false, + enableRequestHeaderTracking: true, + enableResponseHeaderTracking: true, + } + }); + } + + ngOnInit() { + // Even without calling loadAppInsights(), the issue occurs + // this._appInsights.loadAppInsights(); + } +} +``` + +### 4. Configure Server-Side Rendering + +Ensure the application is configured for server-side rendering in `app.route.server.ts`: + +```typescript +import { RenderMode, ServerRoute } from '@angular/ssr'; + +export const serverRoutes: ServerRoute[] = [ + { + path: '**', + renderMode: RenderMode.Server + } +]; +``` + +### 5. Build and Test + +```bash +# Build the Angular application +npm run build + +# Run the application locally using Wrangler +npx wrangler dev +``` + +## Observed Errors + +When running the application, we observe: + +1. Error in the Cloudflare Worker logs: + ``` + Cannot redefine property: name + at defineProperty () + at __name (server.js:7:33) + ``` + +2. The page load hangs indefinitely or is extremely slow. + +## Testing Workarounds + +### 1.

Dynamically Importing ApplicationInsights in Client-Side Only + +Modify `app.component.ts` to conditionally import and initialize ApplicationInsights: + +```typescript +export class AppComponent implements OnInit { + private _appInsights: any; + + constructor() { + this.lazyLoadAppInsights('PLACEHOLDER_CONNECTION_STRING'); + } + + private async lazyLoadAppInsights(connectionString: string) { + try { + // Check if we're in a browser environment (not SSR) + if (typeof window !== 'undefined' && typeof document !== 'undefined') { + const appInsights = await import('@microsoft/applicationinsights-web'); + const ApplicationInsights = appInsights.ApplicationInsights; + + this._appInsights = new ApplicationInsights({ + config: { + connectionString: connectionString, + enableAutoRouteTracking: true, + enableCorsCorrelation: false, + enableRequestHeaderTracking: true, + enableResponseHeaderTracking: true, + } + }); + + this._appInsights.loadAppInsights(); + } + } catch (error) { + console.error('Failed to initialize ApplicationInsights:', error); + } + } +} +``` + +## Analyzing the Built Bundle + +To understand what causes the property redefinition error, we can examine the built bundle: + +```bash +# Find occurrences of property name definition in the bundle +grep -n "defineProperty" server.js +grep -n "__name" server.js +``` + +## Findings and Conclusions + +(This section will be updated after successfully reproducing and analyzing the issue) \ No newline at end of file diff --git a/docs/reproduction/README.md b/docs/reproduction/README.md new file mode 100644 index 000000000..a8f8a80f5 --- /dev/null +++ b/docs/reproduction/README.md @@ -0,0 +1,93 @@ +# ApplicationInsights with Angular SSR in Cloudflare Workers - Issue Reproduction + +This repository contains scripts and tools to reproduce and analyze the issue reported in [ApplicationInsights-JS issue #2523](https://github.com/microsoft/ApplicationInsights-JS/issues/2523), where the ApplicationInsights SDK breaks Angular Server-Side Rendering in Cloudflare Workers. + +## Setup and Reproduction + +This reproducer includes several scripts to help diagnose the issue: + +### 1.

Modifying the esbuild configuration when bundling for Cloudflare Workers -2. Adding specific detection for Cloudflare Workers environments in the SDK -3.
