My Journey

Result

Voila!

The next bit…

Calendar

Lightning Extension

My GSoC Project

1. Adding an offline mode

2. Allowing Changes to be made to calendar in offline and

sync them

3. Helps the use case when you want to travel for days

without Internet connectivity

4. A long standing bug in Mozilla since 2008

DEMO

How did we do it?

• Wrote functions on top of the Caching Wrapper

• Modified the data layer to recognize offline flags

• Caching code handles the provider actions

• Don’t get it?

Want to be the “dropbox” of IVLE Workbin so that

you don’t need to download MBs of notes

everytime you feel like studying.

DEMO

How is it done

• Storing symlinks to the actual files
