Making static sites dynamic with Cloudflare D1

D1 is an SQL database service that allows developers to store and retrieve data quickly in their applications. It can be used alongside other tools like NoSQL and graph databases. D1 provides indexes for fast data retrieval, joins for complex relationships between tables, and a declarative approach to data validation, creation, and querying. The recent release of D1 in open alpha has made it an instant value-add to applications without needing new tools or stepping out of the Cloudflare ecosystem. It enables developers to create stateful applications locally and deploy them easily. In this blog post, the author demonstrates how to use D1 to add comments to a static blog site by creating a new D1 database and building a simple JSON API for comment creation and retrieval. The separation of D1 from the app allows for easier deployment and abstraction of the static and dynamic pieces of the website.
