clickhouse-js-node-troubleshooting
Troubleshoot and resolve common issues with the ClickHouse Node.js client (@clickhouse/client). Use this skill whenever a user reports errors, unexpected behavior, or configuration questions involving the Node.js client specifically — including socket hang-up errors, Keep-Alive problems, stream handling issues, data type mismatches, read-only user restrictions, proxy/TLS setup problems, or long-running query timeouts. Trigger even when the user hasn't precisely named the issue; vague symptoms like "my inserts keep failing" or "connection drops randomly" in a Node.js context are strong signals to use this skill. Do NOT use for browser/Web client issues.
Resumen
ClickHouse Node.js Client Troubleshooting
Reference: https://clickhouse.com/docs/integrations/javascript
⚠️ Node.js runtime only. This skill covers the
@clickhouse/clientpackage running in a Node.js runtime exclusively — including Next.js Node runtime API routes, React Server Components, Server Actions, and standard Node.js processes. Do not apply this skill to browser client components, Web Workers, Next.js Edge runtime, Cloudflare Workers, or any usage of@clickhouse/client-web. For browser/edge environments, the correct package is@clickhouse/client-web.
How to Use This Skill
- Identify the issue — match symptoms to the Issue Index below and read the corresponding reference file.
- Lead with the diagnosis — explain what's likely causing the issue before giving the fix.
- Note version constraints — flag if a fix requires a minimum client version and check it against what the user provided.
- Ask only what's missing — if the fix is version-dependent and you don't know their version, ask; otherwise help immediately.
Issue Index
Identify the user's issue from the list below and read the corresponding reference file for detailed troubleshooting steps.
| Issue | Symptoms | Reference file |
|---|---|---|
| Socket Hang-Up / ECONNRESET | socket hang up, ECONNRESET, intermittent connection drops, long-running queries timing out | reference/socket-hangup.md |
| Data Type Mismatches | Large integers returned as strings, decimal precision loss, Date/DateTime insertion failures, CANNOT_PARSE_INPUT_ASSERTION_FAILED inserting a UUID into a UInt128 column | reference/data-types.md |
| Read-Only User Errors | Errors when using response compression with readonly=1 users | reference/readonly-users.md |
| Proxy / Pathname URL Confusion | Wrong database selected, requests failing behind a proxy with a path prefix | reference/proxy-pathname.md |
| TLS / Certificate Errors | TLS handshake failures, certificate verification issues, mutual TLS setup | reference/tls.md |
| Compression Not Working | GZIP compression not activating for requests or responses | reference/compression.md |
| Logging Not Showing Anything | No log output, need custom logger integration | reference/logging.md |
| Query Parameters Not Interpolated | Parameterized queries not working, SQL injection concerns | reference/query-params.md |
FORMAT Clause / SHOW POLICIES Errors | Syntax error from a duplicate FORMAT, or SHOW [ROW] POLICIES failing even with a format provided | reference/query-format-clause.md |

- clickhouse-best-practicesclickhouseMUST USE when reviewing ClickHouse schemas, queries, or configurations. Contains 31 rules that MUST be checked before providing recommendations. Always read relevant rule files and cite specific rules in responses.11.9 k instalaciones en skills.sh0
- clickhouse-architecture-advisorclickhouseMUST USE when designing ClickHouse architectures, selecting between ingestion or modeling patterns, or translating best practices into workload-specific system designs. Complements clickhouse-best-practices with decision frameworks and explicit provenance labels.8,800 instalaciones en skills.sh0
- chdb-sqlclickhouseUse when the user wants to run SQL — especially analytical SQL — on local files (parquet/csv/json), URLs, S3 paths, or remote databases (Postgres, MySQL, MongoDB, ClickHouse Cloud, Iceberg, Delta Lake) without setting up a server. Provides chDB — embedded ClickHouse SQL in Python with 1000+ functions, Session for stateful multi-step pipelines, parametrized queries, and cross-source joins via `s3()`, `mysql()`, `postgresql()`, `iceberg()`, `deltaLake()`, `remoteSecure()` table functions. TRIGGER when: user wants SQL on parquet/csv/files or across remote analytical sources; uses ClickHouse SQL features (window functions, windowFunnel, geoToH3, JSON path ops, Session, parametrized queries); imports `chdb` or calls `chdb.query()`. SKIP this skill for pandas-style DataFrame method-chaining (use chdb-datastore instead) or ClickHouse server administration.7,900 instalaciones en skills.sh0
- chdb-datastoreclickhouseUse when the user has tabular data (pandas DataFrame, parquet, csv, Arrow, json) and wants to filter, group, aggregate, join, or speed up slow pandas. Provides chDB DataStore — same pandas API, ClickHouse engine underneath. Also handles reading from S3, MySQL, PostgreSQL, MongoDB, ClickHouse Cloud, Iceberg, Delta Lake as DataFrames and joining across sources. TRIGGER when: user mentions DataFrame, parquet, csv, "fast pandas", "speed up pandas", or cross-source DataFrame joins; user imports `chdb.datastore` or `from datastore import DataStore`. SKIP this skill for raw SQL syntax (use chdb-sql instead), ClickHouse server administration, or non-Python DataStore API work.7,600 instalaciones en skills.sh0
- clickhouse-js-node-codingclickhouseWrite idiomatic application code with the ClickHouse Node.js client (`@clickhouse/client`). Use this skill whenever a user is *building* against the Node.js client — configuring the client, pinging, inserting rows in JSON or raw formats, selecting and parsing results, binding query parameters, managing sessions and temporary tables, working with data types or customizing JSON parsing. Do NOT use for browser/Web client code.6,700 instalaciones en skills.sh0
