is-json-schema-subset

Check if a JSON schema is a subset of another

Given a schema defining the output of some process A, and a second schema defining the input of some process B, will the output from A be valid input for process B?

Uses ajv and json-schema-merge-allof.

Usage

import isJsonSchemaSubset from 'is-json-schema-subset';

import inputSchema from './input-schema.json';
import outputSchema from './input-schema.json';

async function check() {
	if (await isJsonSchemaSubset(inputSchema, outputSchema)) {
		console.log('OK');
	} else {
		console.log('Fail');
	}
}

API

import isJsonSchemaSubset from 'is-json-schema-subset';

isJsonSchemaSubset(subset: JSONSchema, superset: JSONSchema, allowPartial: boolean = false)

Returns a promise resolving to true if subset is a compatible subset of superset, else false.

If allowPartial is false, subset must provide all required properties for superset.
