TS Merge Tools

Purpose and audience: the tool targets TypeScript developers, library authors, and teams maintaining multiple type modules who need a single coherent type surface. It merges interfaces, type aliases, and mapped types into a unified set while preserving structural intent. Conceptual workflow: inputs are parsed into an AST, definitions are indexed by name, and merges are applied per a selected strategy. The system supports conflict reporting and optional strategies to tailor results to project needs. Value proposition: reducing manual edits, minimizing drift between modules, and producing consistent type definitions across repos or packages. Core features include name-based merging, property-level reconciliation, union and intersection support, optional recursion-safe merging, and optional conflict reporting. Use cases include consolidating API surface types from design-time and generated sources, merging domain models across microservices, and aligning public typings for a library across versions. Unique differentiators: TypeScript-aware AST merging, preservation of optional properties, and configurable resolution strategies with clear outputs (merged code and a conflict report). Output formats are pure TypeScript definitions suitable for direct inclusion in codebases and for automated diffing with source control.
