hey @hkirat, how should I proceed with mail verification? I can implement it my way but what would suit you the most???

[hkirat]

No need to verify emails for v0

[devsargam]

hey @hkirat, Do we need to support login with appx as a fallback method?

[devsargam]

Also, just to be sure, content is still comming from appx right?

[hkirat]

No all content is in house currently as well
appx gives us

1. authentication (they store user information)
2. Let us know which user has purchased which course - ref - https://github.com/code100x/cms/blob/main/src/utiles/appx.ts#L15

[devsargam]

oh, makes a lot sense. Thanks

[devsargam]

Removed the entire appx dependency from the project

[hkirat]

hmm this might be tricky we need some backward compatability for the current courses

[devsargam]

yep that was what I was basically worried about but seems doable.
I am here to put every ounce of effort for this pr just let me know!!!!

[devsargam]

As this is v0 a lot of things to be improved. LMK your thoughts on this and I shall continue.

PR already getting a lot large and messy.

[devsargam]

@hkirat hoping it comes to your notifs

[hkirat]

Will review it asap

[devsargam]

Just clarifying a few things
I have left a bunch of TODOs which can be their own issue.
Simple enough to fix not totally necessary but can make the app a lot better and performant
not totally sure thooo

[hkirat]

too many merge confs, gonna close for now
