SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents runtime crashes from malformed or unsafe JSON by replacing exception-based parsing with Result-based workflows that fit railway pipelines.

Core Features & Use Cases

Safe parsing without exceptions: Use safeJsonParse to return Result<Json> instead of throwing on invalid input.
Safe stringify with failure reporting: Use safeJsonStringify to return Result<string> and capture common stringify failures like circular references.
Typed parse + validation: Use parseAndValidate with custom type guards (often combining isJson/isJsonObject/isJsonArray) to produce domain-typed results.

Quick Start

Ask your AI to parse the payload with safeJsonParse, validate its shape with parseAndValidate, and return the typed value (or structured errors) for the rest of your pipeline.

FAQPage Schema

How do I parse JSON safely in TypeScript without throwing exceptions?▼

Safe JSON parsing in TypeScript without exceptions uses a safeJsonParse function that returns a Result<Json> object, capturing syntax failures as structured error codes instead of crashing your runtime. This allows pipeline processing to handle malformed input explicitly.

What is the best way to validate JSON shape and structure in TypeScript?▼

Validating JSON shape and structure in TypeScript is best handled by combining custom type guards like isJsonObject and isJsonArray with parseAndValidate, yielding a domain-typed Result. This ensures the parsed payload matches expected structural constraints.

How does Result-based JSON parsing work in railway-oriented programming?▼

Result-based JSON parsing in railway-oriented programming wraps safeJsonParse and safeJsonStringify operations into Result<T> flows, routing success and failure paths separately without throwing. This enables synchronous or async pipelines to propagate errors structurally.

Can I safely stringify JSON with circular references in TypeScript?▼

Safely stringify JSON with circular references in TypeScript by using safeJsonStringify, which returns a Result<string> and reports stringify failures explicitly. This prevents runtime exceptions during serialization of complex or unsafe objects.

How do I handle JSON validation errors structurally in async pipelines?▼

Handling JSON validation errors structurally in async pipelines requires explicit error-code handling for syntax, validation, and stringify failures within the Result<T> flow. This separates error routing from successful payload intake in railway pipelines.
