How to use my own custom js plugin with ionic app?

I created a js plugin using jQuery which I already used in my web application. Now I want use it on my IONIC 3 mobile app.
I installed typings and jquery in my project those are working well there then how I can use my custom jquery plugin in my project.

If you don’t get any better answers, mine is “don’t”. Both Angular and jQuery want control of the DOM, and your app will be more confusing if you try to invite them both.

then what I should do?
