JSON CLI multitool

Swiss Knife

A CLI app to find unordered diff between two JSON documents (based on swaggest/json-diff), generate JSON Schema and Go/PHP code, pretty print, minify, yaml convert, etc....

Build Status Scrutinizer Code Quality Code Climate Code Coverage Image Size Code lines Comments

Purpose

  • To simplify changes review between two JSON files you can use a standard diff tool on rearranged pretty-printed JSON.
  • To detect breaking changes by analyzing removals and changes from original JSON.
  • To keep original order of object sets (for example swagger.json parameters list).
  • To make and apply JSON Patches, specified in RFC 6902 from the IETF.
  • To convert between YAML/JSON/PHP serialization.
  • To resolve JSON Pointer to data.
  • To resolve JSON Pointer to file position.
  • To validate JSON data against JSON Schema.
  • To generate or update JSON Schema with instance value(s).
  • To generate sample JSON value from JSON Schema.
  • To render JSON Schema as Go structure.
  • To render JSON Schema as PHP classes.
  • To render JSON Schema as JSDoc type definitions.
  • To render JSON Schema as Markdown documentation.

Installation

Docker

docker run swaggest/json-cli json-cli --help
v1.6.1 json-cli
JSON CLI tool, https://github.com/swaggest/json-cli
...

json-cli can load schema from stdin (using - as a file path) which can be handy with docker, for example:

cat ./tests/assets/swagger-schema.json | docker run -i --rm swaggest/json-cli json-cli gen-jsdoc -

Composer

Install PHP Composer

composer require swaggest/json-cli

CLI tool

Usage

v1.9.0 json-cli
JSON CLI tool, https://github.com/swaggest/json-cli
Usage: 
   json-cli <action>

            resolve-pos, validate-schema, gen-go, gen-php, gen-jsdoc, gen-json, build-schema

Input paths can be .json/.yaml/.yml/.serialized files, file format is detected by file extension:

  • .yaml, .yml YAML
  • .serialized PHP serialization format
