Node demo

This demo illustrates using the Crash Analyzer support module in a Node project. This application requires Node 19+ to function. However, it will work correctly on older versions of Node -- it just won't add the Source Modules annotation.

Here's output from this demo in Node 16:

> node dist/index

And from Node 20:

Inclusion

At your application's entrypoint, you can import the installation function from the module:

// CommonJS import:
const { installErrorStackModuleAnnotations } = require('@microsoft/edge-devtools-crash-analyzer-support');
// ES Module import
import { installErrorStackModuleAnnotations } from '@microsoft/edge-devtools-crash-analyzer-support';

// Then install it:
installErrorStackModuleAnnotations(Error);

It's possible that you might need to include a // @ts-ignore or // @ts-expect-error comment ahead depending on whether Node typings for Error.prepareStackTrace function. Alternatively, you can register it with an as any cast:

installErrorStackModuleAnnotations(Error as any);
