The code package in Meteor is a bit special and is divided into five types

The code package in Meteor is a bit special and is divided into five types:

• The Meteor core code itself is divided into core packages, each of which is included in each Meteor application, and you basically don't have to expend effort to maintain them.

• Regular Meteor code packages are called "Isopack", or isomorphic code packages (isomorphic package, which means they can work on the server side as well as the client). The first class of code packages such as Accounts-ui or AppCache are maintained by the Meteor core team, bundled with Meteor.

• Third-party code packages are other user-developed Isopack uploaded to Meteor's code package server. You can access the atmosphere or Meteor search commands to browse these code packages.

• The local package is a self-developed code package that is saved in the/packages folder.
  The NPM Code Pack (NPM package) is a code bundle for node. js, although it cannot be used directly with Meteor, but can be used in several of the above code packages
