What is nested-error-stacks?

The nested-error-stacks npm package is used to create Error objects in Node.js that can encapsulate and display a stack trace from another error. This is useful for debugging and error handling when you want to preserve the original error context while adding additional information or handling an error at a higher level in your application.

What are nested-error-stacks's main functionalities?

Creating nested errors

This feature allows developers to create a new error that includes the stack trace of a previous error. The code sample demonstrates how to catch an error and throw a new NestedError that includes the original error's stack trace.

const NestedError = require('nested-error-stacks');

function doSomethingRisky() {
  try {
    // Code that might throw an error
  } catch (error) {
    throw new NestedError('An error occurred in doSomethingRisky', error);
  }
}
