In this video I will create an AWS AppSync API with AWS CDK to build out a product API for a basic E Commerce backend.
The API will enable multiple authorization scenarios - both public and private access - to enable unauthenticated users to read and authenticated users who are part of an Admin group to create, update and delete products.
Workshop materials & code:

In this video, youll learn how to build a full stack NFT marketplace on Ethereum with Solidity, Polygon, IPFS, Next.js, Ethers.js, and Hardhat.
Well start from scratch, creating a new project and installing the dependencies. Well then write and test out the smart contracts. Once the tests have passed, well write the front end code to connect the smart contracts.
After testing on a local network, well deploy to the Matic / Polygon network using a custom RPC provider (Infura).
