Concerto Core

Main library for Concerto model parsing, model manager, JSON instance validation and serialization.

Installation

npm install @accordproject/concerto-core --save

Create a Concerto File

namespace org.acme.address

/**
 * This is a concept
 */
concept PostalAddress {
  o String streetAddress optional
  o String postalCode optional
  o String postOfficeBoxNumber optional
  o String addressRegion optional
  o String addressLocality optional
  o String addressCountry optional
}

Create a Model Manager

const ModelManager = require('@accordproject/concerto-core').ModelManager;

const modelManager = new ModelManager();
modelManager.addModelFile( concertoFileText, 'filename.cto');

Create an Instance

const Factory = require('@accordproject/concerto-core').Factory;

const factory = new Factory(modelManager);
const postalAddress = factory.newConcept('org.acme.address', 'PostalAddress');
postalAddress.streetAddress = '1 Maine Street';

Serialize an Instance to JSON

const Serializer = require('@accordproject/concerto-core').Serializer;

const serializer = new Serializer(factory, modelManager);
const plainJsObject = serializer.toJSON(postalAddress); // instance will be validated
console.log(JSON.stringify(plainJsObject, null, 4);

Deserialize an Instance from JSON

const postalAddress = serializer.fromJSON(plainJsObject); // JSON will be validated
console.log(postalAddress.streetAddress);
