This tutorial is not yet finalized.
In this tutorial you'll be learning about and extending persistent-notes. This application is notes-demo from Tutorial 4 modified to work with MongoDB. The application expects there to be a MongoDB instance running on localhost with notes in the same format as that used by the code in Assignment 5 and Tutorial 5.
Tasks/Questions
- What happens to persistent-notes when mongodb is not running when the app is started? What if it is shut down while the app is running?
- You can stop and start mongodb by typing sudo service mongodb stop and sudo service mongodb start.
- When does the app open a connection to MongoDB? Note that it happens twice.
- You'll notice that restarting the app preserves current sessions. How can you disconnect from a session manually (without "logging out") from the browser? How can you terminate a select session from the server? What about all sessions?
- Implement a delete note button as described in Assignment 6.
