Getting started

1. Import the module into your app.module.ts

  imports: [
    BrowserModule,
    HttpClientModule,
    NgxCorrelationIdModule
  ],

Tip: NgxCorrelationIdModule provide some customization to the underlying https://www.npmjs.com/package/simple-correlation-id package. See release note sections below for details

2. Make a http request

http.get('https://echook.azurewebsites.net/echo').subscribe();

3. Check the request header. There should be a x-correlation-id present

The https://echook.azurewebsites.net/echo API will echo back all HTTP headers sent to it. The response looks like below (notice the presence of x-correlation-id header)

{
  "method": "GET",
  "path": "/echo",
