I was following JSPM getting started guide and I want to install jquery package so I execute below command.
jspm install jquery
But when I try to import it in typescript like below
import $ from 'jquery'
I'm getting a error from typescript compiler saying error TS2307: Cannot find module 'jquery'. Not only for this library for other libraries I'm getting the same error.
You need to include type definitions for jquery in the compilation context, you can grab them from https://github.com/DefinitelyTyped/DefinitelyTyped
