   We will update the `package.json` file to define the main modules in our Meteor app:
  
positive.code: image::https://user-images.githubusercontent.com/2006548/84450825-9c21a300-ac51-11ea-9243-78a13ecad82d.png[]
  
  To fix that, we will add a declaration file:
  ```shell 
  #under meteor-elm-app
  mkdir -p types/meteor
  
negative.code: meteor npm i -D parcel
  ```
  
  === Create a Meteor package
  
  This Meteor package will contain our Elm application.
