Implementing a Wasm Native Database API with Couchbase
summary
Shows a concrete WIT-driven integration: three interfaces (WASI-Keyvalue, Couchbase Subdoc, Couchbase Query) implemented and exposed via a wasmCloud provider, with generated Go bindings used by a newbase component. Workshop uses Gitpod + wash + tinygo to build and run a local Couchbase cluster (admin/password on port 8091) and exercises document CRUD, JSON Patch application, CAS optimistic locking and replace operations. Repo contains runnable dev flow and an unfinished batch upsert handler left for attendees; overall demo runs but required creating a newbase bucket to succeed.
