Validate element templates based on JSON Schema.
npm i --save @bpmn-io/element-templates-validatorGiven 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));
