This sample demonstrates how to use WebAssembly Components within a Spin application.

• ACME - acts as an webhook producer (localhost:3000)
• CYBERDYNE - acts as a webhook consumer (localhost:3001)
• WONKA - acts as a webhook consumer (localhost:3002)

• hmac - provides capabilities to sign data and verify those signatures

• Rust with wasm32-wasi target must be installed
• Cargo Component must be installed
• Wasm Tools must be installed
• Spin must be installed

Use the Makefile to compile and compose all necessary Wasm Components.

Running each of the following in a dedicated terminal session:

• make start-acme
• make start-wonka
• make start-cyberdyne

Run make register-wonka (as of writing this, this removes all previously registered webhooks for demonstration purposes) to register the wonka service as webhook consumer. Run make fire-webhook to make ACME fire a webhook
