What is go-jsonschema?

go-jsonschema is a tool for generating Go data types and structs from JSON Schema definitions. It also generates unmarshalling code that validates JSON input against the schema's validation rules. go-jsonschema is written in Go.

Key features of go-jsonschema

  • go-jsonschema generates Go data types and structs corresponding to JSON Schema definitions.
  • go-jsonschema generates unmarshalling code that validates input JSON according to schema validation rules.
  • go-jsonschema can generate code for multiple schemas in one run and write output to different files inside different packages.
  • go-jsonschema supports references against top-level names in the same schema and in external files.
  • go-jsonschema provides SerializableDate and SerializableTime types for JSON serialization and deserialization.
  • go-jsonschema supports validation features including enum, type, numeric constraints, string constraints, array constraints, required properties, properties, and dates and times.

How omissis/go-jsonschema works

Schema files enter through the go-jsonschema command, which can process one or more JSON Schema definitions in a run. The generator creates Go source code for the schema's data types and structs, then emits unmarshalling code for validating JSON input. Generated output can be written to standard output or mapped to files and packages with schema package and schema output options. The pkg directory holds the library code, while the internal directory contains internal implementation code. The tests directory contains test files and golden files used to check generated output, and the scripts directory contains project scripts.

Getting started with go-jsonschema

  1. Generate Go source for schema.json under package main.
    go-jsonschema -p main schema.json

go-jsonschema is a tool that generates Go data types, structs, and validating unmarshalling code from JSON Schema definitions.

How does go-jsonschema work?

go-jsonschema reads JSON Schema files and writes generated Go source to standard output or configured files and packages. The generated unmarshalling code validates JSON input against schema rules.

How do I install go-jsonschema?

go-jsonschema can be installed from source with Go 1.25 or later using go get and go install. It can also be installed with Homebrew.

What language is go-jsonschema written in?

go-jsonschema is written in Go.

How is the go-jsonschema code organized?

go-jsonschema organizes library code in pkg and internal implementation code in internal. Tests and golden files are in tests, and project scripts are in scripts.

Who is go-jsonschema for?

go-jsonschema is for developers who need Go data types and validating unmarshalling code generated from JSON Schema definitions.

What license does go-jsonschema use?

go-jsonschema uses the MIT license.

About this page

Get a page like this for your own codebase

Repowise built this map of omissis/go-jsonschema from its source and git history. It parses every symbol, draws the dependency graph, scores each file's health from complexity, duplication, coverage and churn, finds hotspots and owners in the history, and writes documentation for every module. Your coding agent reads the same index over MCP, so its answers cite real files.
