Camunda FEEL Builtins

Collection of builtin Camunda extensions for FEEL (Friendly Enough Expression Language). These builtins get extracted from camunda-docs.

Installation

Install via npm:

npm install @camunda/feel-builtins

Usage

Feel Editor

In your FEEL editor you can use these builtins to establish the Camunda context:

import { camundaBuiltins } from '@camunda/feel-builtins';
import FeelEditor from '@bpmn-io/feel-editor';

const editor = new FeelEditor({
  container,
  builtins: camundaBuiltins,
  parserDialect: 'camunda'
});

Feel Lint

With @bpmn-io/feel-lint you can also use the builtins to lint expressions in the Camunda world:

import { camundaBuiltins } from '@camunda/feel-builtins';
import { lintExpression } from '@bpmn-io/feel-lint';

lintExpression(expression, {
  builtins: camundaBuiltins,
  parserDialect: 'camunda'
});
