Incorporate an external JS file (File A) that is dependent on another JS file (File B) into a TypeScript file within the context of Angular 4

Working on an Angular 4 project, I recently installed two external JS libraries using npm. They are now in the node_modules folder and usable in another TS file within my project. The issue arises because import B requires import A, preventing me from effectively using them together in a single TS file.

Does anyone have a solution to this problem?

I attempted importing both files in the same TS file with no success.

Thank you for any assistance!

When using the Angular CLI and installing packages with NPM, you do not have to include them in the scripts section of your angular-cli.json file. This section is only for scripts included in other ways and essentially means including script tags inline.

All you need to do is add this statement to File A:

import {NameOfModule} from "name of file B";

Typically, this information can be found in the package documentation. If it doesn't work, try locating the main module that the library exports, usually in an index file.

If import A requires import B, it should handle that internally rather than requiring action on your part.
