The problem NBA TOPSHOT Reviews solves

The NBA Topshot Reviews DAPP is built on flow chain using NBA TopShot. Users of our DAPP can rate, review and share their favorite moments with the community. Community will be able to see the ratings and reviews from other users and will be able to make an informed decision before trading.

Challenges we ran into

1. We struggled for almost 2 days to fetch NBA Top Shot Moments data using cadence scripts and also using Graphql queries. We cant get the required data for our app using cadence queries, so we tried to fetch using graphql. Then we got CORS errors from Graphql public end point. We tried different methods, but none of them worked. Then we created a proxy node server to call graphql queries which ultimately worked.

2. Cadence vscode extension is not working in Windows Machine. Also, Flow CLI is not working as expected in Windows machine. So struggled for hours in fixing the issue then finally switched to MAC to do coding of contract.
