ncode TS Generator

The tool translates a concise high-level specification into TypeScript code templates to scaffold domain models, services, and API clients. Target users are TypeScript engineers, backend architects, and platform teams seeking repeatable boilerplate with consistent structure. A spec provides target_ts_version, module_system, entities with fields, and optional features such as include_validation, include_tests, or client methods; the output consists of ready-to-customize templates that align with project conventions and TypeScript best practices.
Core Logic & Features: Required features include spec parsing and strict validation, template rendering for core artifacts (models/interfaces, services, API clients, and DTOs), type mapping for primitives and user-defined types, and basic dependency resolution to avoid name clashes. Optional features include conditional template sections, customizable naming strategies, versioned template packs, and pluggable backends for file output or in-memory delivery. The system enforces TypeScript syntax rules, reserved keyword checks, and circular dependency detection. It supports ESModule and CommonJS modes and can adapt outputs to a specified TS version.
Inputs & Outputs: Inputs include target_ts_version (string, e.g., '4.9'), module_system (string, 'ESNext' or 'CommonJS'), entities (array of {name:string, fields:[{name:string, type:string, optional:boolean}]}), include_tests (bool), include_validation (bool). Outputs are artifacts such as model.ts, service.ts, client.ts, dto.ts, tests.ts emitted as code strings or file outputs, with standard TS formatting and import/export conventions. Outputs preserve type safety, correct nullability, and consistent naming across artifacts.
Algorithms & Calculations: Internally a template engine applies a spec-driven mapping: entity fields map to interfaces/classes, generators create constructors or factories, derive DTOs when include_validation is true, and build API client templates from endpoint-like specs. Dependency resolution avoids duplicate names and wires types through imports. The approach aims for deterministic results across runs.
Error & Edge Cases: Missing required inputs (e.g., entity name or field type) trigger validation errors. Unknown field types, unresolved dependencies, or conflicting template variants yield explicit errors and revert to safe defaults. Incompatible TS version or module system emits a clear error with guidance.
Industry/Region & Localization: Defaults to US English identifiers; localization hooks exist for future updates. Assumptions & Exclusions: This tool generates scaffold code and does not execute runtime logic; no UI rendering or deployment steps.
