Conformance

To conform to this standard, a package must:

• link to the final published version of this specification
• specify the compiler support policy
• specify the currently-supported versions of TypeScript
• specify the definition of “public API” used by the library (e.g. “only documented types” vs. “all published types” etc.)
• author and publish its types with strict: true, noUncheckedIndexedAccess: true, and exactOptionalPropertyTypes: true in its compiler configuration
• always fully specify optional properties on objects with both ? and | undefined
