@nudojs/service

Nudo analysis core and emit products: Abs-native file analysis, evaluator host API, interface/dts/schema/guard projections, and session caches.

What is Nudo?

Nudo is a type inference engine for JavaScript. The type system is Abs (shape × term × pred × conf); production analysis is Abs-native via abstract interpretation — no TypeScript, no build step.

This package

@nudojs/service provides the analysis core used by CLI, editor extensions, and build tools, plus the emit faces that project Abs to dts/schema/guard/interface.

Production evaluation is Abs-native evaluator (evalAbsModuleGraph + runTranspiled); the TypeValue AST interpreter is gone. Prefer a focused subpath over the full barrel:

| Subpath | Face | |---|---| | @nudojs/service/analysis | File analysis, diagnostics, call records, Abs module-graph eval | | @nudojs/service/evaluator | Host API surface (env/config/CallRecord) — not the eval engine | | @nudojs/service | Full barrel (stable; analysis face) |

Emit products live in @nudojs/service/emit (interface/contract, dts, schema, guard, case reports). IDE surface lives in @nudojs/lsp; @types harvest in @nudojs/harvester.

Highlights:

• File analysis — analyzeFile returns diagnostics, function analyses, and case results
• Module graph — evalAbsModuleGraph evaluates a file's import closure as Abs
• Session caches — analysis / fn / evaluator caches with eviction and project-config limits

Install

npm install @nudojs/service
