SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bridges typed OCaml code with JSON data safely, reducing runtime errors when parsing or generating JSON.

Core Features & Use Cases

  • Type-safe OCaml codecs for Jsont that map between OCaml records and JSON objects.
  • Support for nested structures, optional fields, and lists via composed codecs.
  • Use cases include encoding/decoding configuration, API payloads, and data interchange in OCaml apps.

Quick Start

Create a codec for your OCaml types and use decode/encode to convert between OCaml values and JSON strings.

Frequently Asked Questions about jsont

FAQPage Schema
How do I parse JSON into OCaml records safely?▼

Type-safe JSON encoding in OCaml maps records to JSON objects via composed codecs. You create a codec for your OCaml types and use encode to generate JSON strings for API payloads or configuration files.

Can I handle nested structures and optional fields when decoding JSON in OCaml?▼

Yes, decoding nested JSON structures in OCaml is supported by composing small codecs into larger structures. This approach handles optional fields and lists by mapping typed OCaml code with JSON data safely.

What libraries are required for type-safe JSON encoding and decoding in OCaml?▼

Type-safe JSON encoding in OCaml requires the Jsont and Jsont_bytesrw libraries. These dependencies provide the codec framework needed to map between OCaml values and JSON strings without runtime errors.

What is the best way to avoid runtime errors when generating JSON from OCaml types?▼

The best way to avoid runtime errors when generating JSON from OCaml types is using type-safe codecs. This approach bridges typed OCaml code with JSON data safely by validating structures during the encoding process.

Does type-safe JSON decoding work for API payloads and configuration in OCaml apps?▼

Type-safe JSON decoding works for API payloads and configuration in OCaml apps by mapping JSON objects to OCaml records. It supports data interchange tasks by composing codecs for nested structures and optional fields.
