Warning This repository is for Miniflare 2, which is only receiving critical security updates. Miniflare 2 simulated the Workers runtime and the rest of the Cloudflare developer platform using Node.js. New versions of Miniflare can be found in the workers-sdk repository, and use the open-sourced Workers runtime workerd. This practically eliminates behaviour mismatches between development and production deployments. We recommend you migrate to Miniflare 3 now if you can. Whilst Miniflare 3 supports most of Miniflare 2's features, one key omission is the unit testing environment. We're actively working on adding support for this to Miniflare 3. Once this is supported, we're planning to deprecate Miniflare 2 and archive this repository.
