JSON Schema

Parser to convert condensed JSON schemas to standard ones.

Overview

This is a parser that generates a fully qualified JSON Schema based on 'condensed' JSON schema input. From Understanding JSON Schema:

JSON Schema is a powerful tool for validating the structure of JSON data.

Rationale

JSON Schema is extremely useful for validation purposes; however, in some use cases it may also be more verbose than necessary. This tool was created to allow users of Fractal to add specifications to their components, whilst hiding some of the complexity of the full specification.

const schemaExpander = require('@frctl/json-schema');

const schema = schemaExpander.expand({ title: 'string', modifier: 'string' });

console.log(schema);

/*
Outputs:

{
  "$schema": "http://json-schema.org/schema#",
  "type": "object",
  "properties": {
    "title": {
      "type": "string"
    },
    "modifier": {
      "type": "string"
    }
  }
}

*/

Installation

npm i @frctl/json-schema --save

API

.expand(schema)

Returns a fully qualified JSON schema.

• schema: A Condensed JSON schema

const schema = jsonSchema.parse({ title: 'string', modifier: 'string' });

• If a valid condensed schema is provided, a converted, fully qualified schema will be returned.
• If an already fully qualified schema is provided, it will return that.
• If an invalid schema is provided, it will return an empty schema (i.e. all data will validate).
