If external library like jQuery is installed using NPM
npm install --save jquery
Add script path into your angular-cli.json
"scripts": [
"../node_modules/jquery/dist/jquery.js"
]
You can also save the library file in your assets/js directory and include the same in angular-cli.json
"scripts": [
"assets/js/jquery.js"
]
Save your main library jquery and their dependencies like jquery-cycle-plugin into the assets directory and add both of them into angular-cli.json, make sure the order is maintained for the dependencies.
To use jquery in your Angular 2.x components, declare a global variable on the top
If using $ for jQuery
declare var $: any;
If using jQuery for jQuery
declare var jQuery: any
This will allow using $ or jQuery into your Angular 2.x component.
