typebox/changelog/0.18.0.md

0.18.0

Changes:

• Function Type.Intersect(...) is now implemented with allOf and constrained with unevaluatedProperties (draft 2019-09)
• Function Type.Dict(...) has been deprecated and replaced with Type.Record(...).
• Function Type.Strict(...) now includes the $schema property referencing the 2019-09 draft.

Type.Intersect(...)

TypeBox now targets JSON schema draft 2019-09 for expressing Type.Intersect(...). This is now expressed via allOf with additionalProperties constrained with unevaluatedProperties. Note that unevaluatedProperties is a feature of the 2019-09 specification.

Type.Record(K, V)

TypeBox has deprecated Type.Dict(...) in favor of the more generic Type.Record(...). Where as Type.Dict(...) was previously expressed with additionalProperties: { ... }, Type.Record(...) is expressed with patternProperties and supports both string and number indexer keys. Additionally, Type.Record(...) supports string union arguments. This is analogous to TypeScript's utility record type Record<'a' | 'b' | 'c', T>.

0.17.7
