ClickHouse SDK Patterns

Overview

Production patterns for @clickhouse/client — typed queries, streaming inserts, error handling, and connection lifecycle management. Start from the typed query helper below, then drill into references/implementation.md for the streaming, batching, and lifecycle patterns.

Prerequisites

• @clickhouse/client installed and authenticated (see clickhouse-install-auth)
• Node.js 18+ with a CLICKHOUSE_HOST / CLICKHOUSE_USER / CLICKHOUSE_PASSWORD env set
• Familiarity with async/await and Node.js streams (backpressure, drain, Readable)

Instructions

Apply the pattern that fits your workload. Steps 2–7 live in references/implementation.md with full, copy-pasteable code; the core typed-query skeleton stays here.
