jsont

What problem does it solve?

This Skill provides a type-safe approach to encoding and decoding JSON in OCaml by leveraging the jsont library. It helps you define codecs for OCaml records, ensuring JSON structures conform to your types and preventing runtime errors during data exchange.

Core Features & Use Cases

• Type-safe object codecs: Define codecs for OCaml records using Jsont.Object to map required fields
• Optional fields and defaults: Use opt_mem to handle missing fields with sensible defaults
• Nested structures and lists: Compose codecs for nested objects, lists, and maps; support null values with Jsont.null
• Practical use cases: Parse JSON responses from APIs, validate configuration files, and serialize OCaml data to JSON

Quick Start

Start by adding the Jsont dependency to your OCaml project, then create a module defining your data types and their codecs. Use decode and encode helpers to convert between JSON and OCaml values.
