Fast Storage - Netlify Blob challenge

This is a submission for the Netlify Dynamic Site Challenge: Build with Blobs.

What I Built

I want to build a webapp to support freelancer, software engineers to host their digital products quickly for their MVP. Previously, I would host my downloadable resources on S3 and share with my customers or put it into my landing pages. However, I hate the fact that I have to update this link on all my pages every time when I update new version of the file.

So what I want to have is:

1. Easily create a product with a downloadable digital file.
2. Get a fixed + permanent link for the product. Every time I update the product by uploading a new file, the link won't need to be changed.
3. Able to create an auto expiration link for a product so that I can use it for any email or promotion campaigns. The link will live for a period that I defined and then it will be invalidated without me doing any thing.

Demo

All the features I built in last few days are listed in this landing page here: https://regal-madeleine-9b4642.netlify.app/

Platform Primitives

I'm using Netlify Blobs to store both the products' photo and binary files. The products and the Blobs' keys are then stored into a DynamoDB table so that I can manage them properly.

DynamoDB also comes handy with the ability to expire an item. I used this for the short-live link features.

I'm using Next.js Image so it will leverage Netlify Image CDN as well.
