TypeScript has been updated to the latest stable version. Additionally, the version range has been updated to use
~
because TypeScript does not follow SemVer (they make breaking changes as minor updates).The configuration has been updated to match the module template, except that two options (
exactOptionalPropertyTypes
andnoUncheckedIndexedAccess
) have been omitted temporarily to reduce the number of changes required for this update. They can be added in later PRs.Just as in the module template, a separate
tsconfig
file has been created to distinguish build settings from settings used to compile unit tests.The one configuration difference is the compilation target. The target is ES2019 here because this is a developer tool, so we don't need to stick to ES2017 for browser compatibility.
