@clickhouse/client - npm Package Versions

0.0.14

New features

• Added support for JSONStrings, JSONCompact, JSONCompactStrings, JSONColumnsWithMetadata formats (@andrewzolotukhin).

0.0.13

New features

• query_id can be now overridden for all main client's methods: query, exec, insert.

0.0.12

New features

• ResultSet.query_id contains a unique query identifier that might be useful for retrieving query metrics from system.query_log
• User-Agent HTTP header is set according to the language client spec. For example, for client version 0.0.12 and Node.js runtime v19.0.4 on Linux platform, it will be clickhouse-js/0.0.12 (lv:nodejs/19.0.4; os:linux). If ClickHouseClientConfigOptions.application is set, it will be prepended to the generated User-Agent.

Breaking changes

• client.insert now returns { query_id: string } instead of void
• client.exec now returns { stream: Stream.Readable, query_id: string } instead of just Stream.Readable

Breaking changes

• log.enabled flag was removed from the client configuration.
• Use CLICKHOUSE_LOG_LEVEL environment variable instead. Possible values: OFF, TRACE, DEBUG, INFO, WARN, ERROR. Currently, there are only debug messages, but we will log more in the future.
