Default client entry for Ghost frontend

[sebgie]

This belongs to the OAuth Epic: #4004 - please read this for the big picture of what this issue is for :)

This requires #4180 in order to work.

To make life for theme developers a bit easier it would be nice to add a default entry into the client table for the Ghost front end. A theme developer would be able to use the pre populated client_id to implement custom JavaScript functionality.

To allow JavaScript access out of the box for themes a new client entry would have to be added during migration.

What exactly is the goal here? A client side JavaScript API implementation for theme devs so they can fetch public data from the API?

[sebgie]

@halfdan no, not that complicated. I was thinking of a default entry in the client table and maybe a helper that outputs the client_id on the front end. A real JavaScript API would be nice, but I think this is something post 1.0 release.

Potential implementation here.
This implements the casper theme on an angular app. Because open oauth isn't yet available, it does depend on some workarounds.

@patrickdbakke I think you may have misunderstood what this issue is about? I've updated it to make it a little clearer.
