使用外部JS库Angular 2

Question

I want to use the simple example dropzone js in an angular 2 project: http://www.dropzonejs.com/examples/simple.html

Is there an easy way to use the js for simple drag and drop functionality? I tried adding installing using:

npm i dropzone --save

And referencing the script from node_modules in index.html, but it doesn't seem to work.

Answer 1

Currently, The easiest way to include an external library into an angular 2 project is as follows:

1) include it in your HTML file as a script tag

<script src="js/your-library.js"></script>

2) To use the library you must add the following to one of your ts/js files:

declare var libraryVar: any;

or

var libraryVar

Where libraryVar is the name of a function from the library you're including, so for example, to include jQuery, you would use:

declare let $:any;
