Weekend project

• Build a web server and API for providing the features using the RESTful architecture
• Run a local node of IPFS
• Upload 10 images to this node
• Create a JSON and build metadata descriptions for 10 NFTs, each using one unique image
• Make a GET method in the API to get the metadata by id
• Deploy a NFT Collection and mint 10 NFTs, and assign the API endpoint to the token URI
• Integrate this NFT Collection contract and APIs in a frontend application to display NFTs metadata and images
• (Bonus) provide wallet functions in the frontend to buy, transfer, allow, transfer from and burn NFTs
