Clickhouse Js Node Coding

It covers the practical stuff: configuring connections, inserting rows in JSONEachRow or raw formats, querying with proper parameter binding, managing sessions and temporary tables, and handling modern ClickHouse types like Dynamic and JSON. The skill enforces one critical rule: always use query_params for user input and explicitly call out SQL injection risk when showing parameter binding, because developers coming from PostgreSQL or MySQL consistently miss this. It won't help with browser code, Edge runtime, or debugging connection errors. Those have separate skills. If you're building a Node.js backend that talks to ClickHouse, this gives Claude the reference material to generate idiomatic client code instead of generic guesses.
