Changelog — @clickhouse/datatype-parser

This file tracks the standalone @clickhouse/datatype-parser package. Entries relevant to it (through @clickhouse/client 1.23.0) were previously recorded in the now-frozen repository-wide CHANGELOG.md.

0.1.3

Migration Notes

  • Node.js 18.x is no longer supported. The engines.node floor was raised from >=18.0.0 to >=20. Node.js 20.x, 22.x, 24.x, and 26.x are supported and exercised in CI. (#906)

0.1.2

New features

  • Initial published release of @clickhouse/datatype-parser: a small, dependency-free standalone parser for ClickHouse data-type strings (the kind sent in the types row of RowBinaryWithNamesAndTypes, e.g. Array(Nullable(UInt64)), Tuple(a UInt8, b String), Enum8('a' = 1)). It is a faithful port of the server's ParserDataType and emits a JSON AST that is byte-identical to the server's EXPLAIN AST json = 1 data-type subtree (parseDataType plus its Node AST). It supersedes the deprecated parseColumnType exported from @clickhouse/client, @clickhouse/client-web, and @clickhouse/client-common. (#893)
