Develop

Validation

The validation script pnpm validate provides basic validation of the config file using Oxlint itself to load, parse, and resolve the config file. It errors on malformed JSON and schema violations including wrong types, rule-name mistakes, bad category names.

Note: Oxlint writes errors to stdout, not stderr, so outputs are captured and printed only on error.

Changelog

v0.4.0 (2026-9-6)

• Add rules.
• Etc.: Improve README and update deps.

v0.3.0 (2026-5-19)

• Disable typescript/prefer-readonly-parameter-types. Agree in theory but too noisy. Too many legitimate readonly types are flagged as mutable due to the rule's strict internal model, e.g. HTMLElement, Date, AbortSignal, etc. Disables the rule rather than maintaining an ever-growing allowlist.

v0.2.1 (2026-5-15)

• Fix prefer-readonly-parameter-types allowlist with comment-explanation.

v0.2.0 (2026-5-15)

• Add Response as exception to typescript/prefer-readonly-parameter-types.
• Update dep: oxlint.
