Microscope is a simple social news app that lets you share links, comment, and vote on them.

It was built with Meteor as a companion app to The Meteor Book, and is the "little brother" of Telescope, the (much more complex) open-source social news app that was the inspiration for the book.

Microscope itself is free and open-source, and is a good example of common Meteor app patterns such as:

  • Routing
  • User Accounts
  • Notifications
  • Errors
  • Publications/Subscriptions
  • Permissions
