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.

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"
  }
}

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.

Use the bpmnlint playground to implement new rules with quick visual feedback.

For more details on how to define and consume custom lint rules check out the bpmnlint-plugin-example.
