Package Exports

@bpmn-io/element-templates-validator
@bpmn-io/element-templates-validator/dist/index.cjs
@bpmn-io/element-templates-validator/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@bpmn-io/element-templates-validator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

element-templates-validator

Validate element templates based on JSON Schema.

Installation

npm i --save @bpmn-io/element-templates-validator

Usage

Given an example element template:

import { validate } from '@bpmn-io/element-templates-validator';

import sample from './test/fixtures/rpa-broken.json';

const {
  valid,
  errors
} = validate(sample);

if (!valid) {
  console.error('Invalid JSON detected:', errors);
}

This will print detailed information about errors inside the sample:

[
  {
    "keyword": "type",
    "dataPath": "",
    "schemaPath": "#/type",
    "params": {
      "type": "object"
    },
    "message": "must be object",
    "dataPointer": {
      "value": {
        "line": 0,
        "column": 0,
        "pos": 0
      },
      "valueEnd": {
        "line": 177,
        "column": 1,
        "pos": 4825
      }
    }
  }
  ...
]

It's also possible to validate multiple objects at once

import { validateAll } from '@bpmn-io/element-templates-validator';

import samples from './test/fixtures/multiple-errors.json';

const {
  valid,
  results
} = validateAll(samples);

if (!valid) {
  console.error('Invalid JSON objects detected:', results.filter(r => !r.valid));
}
