Convert JavaScript code to Typescript code [closed]

  angular, javascript, typescript

I have a huge JavaScript project with over 10000 lines which is a open source project. I am trying it to make it as a angular project so now I need to convert it to Typescript as fast as I can. I tried some npm libraries also to convert them but they did nothing.So somebody help me through how to convert js to ts. Thank you.
