Rules

Our documentation lists all currenty implemented rules, the ./rules folder contains each rules implementation.

Do you miss a rule that should be included? Propose a new rule.

Configuration

Create a .bpmnlintrc file in your working directory and inherit from a common configuration using the extends block:

{
  "extends": "bpmnlint:recommended"
}

Add or customize rules using the rules block:

{
  "extends": "bpmnlint:recommended",
  "rules": {
    "label-required": "off"
  }
}

API

Invoke the tool directly from NodeJS:

import Linter from 'bpmnlint';
import NodeResolver from 'bpmnlint/lib/resolver/node-resolver';

import BpmnModdle from 'bpmn-moddle';

const moddle = new BpmnModdle();

const linter = new Linter({ 
  config: {
    extends: 'bpmnlint:recommended'
  },
  resolver: new NodeResolver()
});

const xmlStr = `
  <?xml version="1.0" encoding="UTF-8"?>
  <bpmn:definitions xmlns:bpmn="http://www.omg.org/spec/BPMN/20100524/MODEL" 
                     id="definitions" 
                     targetNamespace="http://bpmn.io/schema/bpmn">
    <bpmn:process id="process" />
  </bpmn:definitions>
`;

const {
  rootElement: definitions
} = await moddle.fromXML(xmlStr);

const reports = linter.lint(definitions);

// {
//    "end-event-required": [
//      {
//        "id": "process",
//        "message": "Process is missing end event"
//      }
//    ],
//    ...
// }

Writing a Plug-in

Create your first plug-in using the plugin creator:

npm init bpmnlint-plugin {PLUGIN_NAME}

Checkout the bpmnlint-plugin-example for details on how to define, test, and consume custom lint rules. Use the bpmnlint playground to implement new rules with quick visual feedback.

Bundling

For browser usage include your linting configuration using your favorite bundler plug-in (Rollup, Webpack).

Visual Feedback

Integrate the linter via bpmn-js-bpmnlint into bpmn-js and get direct feedback during modeling.

To try out visual validation, checkout the bpmnlint playground.
