This extension makes Miniflare (dev environment for Cloudflare workers) available directly in LocalStack!

⚠️ Please note that this extension is experimental and currently under active development.

localstack extensions install "git+https://github.com/localstack/localstack-extensions/#egg=localstack-extension-miniflare&subdirectory=miniflare"

To publish the sample application to Miniflare running in LocalStack, we can use the wrangler CLI with the following environment variables for local dev mode:

export CLOUDFLARE_API_TOKEN=test
export CLOUDFLARE_API_BASE_URL=http://localhost:4566/miniflare
wrangler publish

Note: if you're having troubles with this configuration, e.g., seeing "Fetch failed" error messages on wrangler publish, try using this API endpoint instead:

export CLOUDFLARE_API_BASE_URL=https://localhost.localstack.cloud:4566/miniflare

Once deployed, the Cloudflare worker can be easily invoked via curl:

$ curl http://hello.miniflare.localhost.localstack.cloud:4566/test
Hello World!
