bpmn moddle bpmn20 meta-model

be-moddle

Backend Preffered Moddle

Read and write BPMN 2.0 diagram with blockchain, Hooks & APIs blocks to files in NodeJS and the browser.

solyd-moddle uses the BPMN 2.0 meta-model with extensions for blockchain and APIs to validate the input and produce correct BPMN 2.0 XML.

Usage

Get the library via npm package. Consume it in NodeJS, via UMD or bundle it for the browser using your favorite module bundler.

BPMN2.0 with Blockchain

const BpmnModdle = require('solyd-moddle');

main()
async function main(){
  const moddle = new BpmnModdle();
