Introduce the ability to define reusable types within CSV files using
comment lines with the format `# TypeName := schema`.
- Support parsing type declarations from comments or schema cells
- Enable recursive expansion of type names within schemas
- Integrate declared types into generated TypeScript definitions
- Allow columns to reference declared types by name
Update the code generation in `csvToModule` to use a more concise
mapping pattern for row resolvers, removing the unnecessary object
spread and nested braces.
Split the monolithic `src/csv-loader/loader.test.ts` into multiple
specialized test files to improve maintainability and readability:
- `parseCsv-basic.test.ts`: Primitive types, arrays, and tuples
- `parseCsv-caching.test.ts`: Table caching logic
- `parseCsv-circular.test.ts`: Circular reference detection
- `parseCsv-combinators.test.ts`: References in unions and tuples
- `parseCsv-noResolveRefs.
Replace the custom `ReferenceValueParser` class with the core
`parseValue` function in `reference-resolver.ts`. This simplifies
the logic for parsing reference IDs and ensures consistency with the
rest of the schema parsing engine.
- Add unit tests for accessor-based output, circular references,
and reverse reference resolution in `csvToModule`.
- Extract fixture loading logic into `test-utils.ts`.
- Refactor `loader.test.ts` to use the new test utilities.
generation
Extract reference resolution logic, type generation, and module
generation into dedicated modules to improve maintainability and
clean up the core loader.
Update `csvToModule` to check if a foreign key value is an object
containing the default primary key before converting it to a string.
This ensures correct key mapping when references are resolved as
objects rather than primitive IDs.
Pre-filter comment lines from the content before passing it to
`csv-parse`. This prevents quote parsing errors when comment lines
contain double quotes and simplifies the record filtering logic.
Support reverse references via ~tablename(foreignKey) syntax,
complementing forward @tablename references. Includes parser,
validator, and CSV loader integration with the new
ReverseReferenceSchema type.
