Doubling down on local development with Workers: Miniflare meets workerd

Miniflare 3, a local Cloudflare Workers simulator, has been released with improved accuracy and compatibility due to its use of the recently open-sourced workerd runtime. This new version simplifies the implementation by removing over 50,000 lines of code from Miniflare 2 while retaining features like live reload and detailed logging. Additionally, an experimental feature allows developers to access real data from Cloudflare KV namespaces locally. The Wrangler CLI will be updated in the future to make local development the default experience, offering significant performance improvements. The Workers team plans to focus on improving automated testing and creating IDE extensions for easier development of workers.
