I have an Angular2 application that uses Leadtools. It uses Angular-CLI and webpack to build.

When I attempt to even place the Leadtools.Documents.d.ts in my application folder structure, I get the following error:
Cannot read property 'length' of undefined
TypeError: Cannot read property 'length' of undefined

Removing this file removes the error.

Any help would be appreciated.

Hello Kevin,

Apologies for the long delay before getting a response from us. There is an issue on the angular-cli github that appears to be exactly what you're experiencing: https://github.com/angular/angular-cli/issues/5053.
Looking through that, it could a number of things, here are two to check for starters:

Ensure any file referenced in the .d.ts files via ///<reference path="./foo.d.ts" /> exists
Check if you have a file environment.prod.ts, below is an example from one of the users on the issue linked above

Code:


export const environment = {
  production: true,
  silent: false
};

Thank you. The references in Leadtools.Documents.d.ts was the problem.
I changed:
/// <reference path="jquery/jquery.d.ts" />

To point to the jquery index file in my node-modules:
/// <reference path="../../../../../node_modules/@types/jquery/index.d.ts" />

This solved my issues.
