dts-test

Tests TypeScript types to ensure the types remain as expected.

This directory is included in the root tsconfig.json, where package imports are aliased to src directories, so in IDEs and the pnpm check script the types are validated against source code.
When running tsc with packages/dts-test/tsconfig.test.json, packages are resolved using normal node resolution, so the types are validated against actual built types. This requires the types to be built first via pnpm build-types.
