title: How to import libraries that are not on npm registry in a webpack-built application?
body: <p>I have a react application written in typescript that uses webpack to compile. So far, I could import libraries through the <code>import</code> keyword from node_modules. </p>
  
  <p>However, there are a few libraries I would like to use that are not on the npm registry. So I can't do a npm install of these libraries. For example, Papa Parse is one of those that I can't quite find its npm package. They usually only provide a minified js file which I can't just import into my Typescript file. </p>
  
  <p>For applications that uses webpack to build, how can I use libraries that are not on the npm registry in my code? </p>
