Error Handling

This guide covers common error scenarios and how to handle them.

Invalid JSONPath

import { JSONPath } from '@jsonpathx/jsonpathx';

try {
  JSONPath.parse('$.invalid..path');
} catch (error) {
  console.error('Invalid path:', error.message);
}

Query Errors

try {
  const result = await JSONPath.query('$.items[*]', data, {
    eval: 'safe',
    ignoreEvalErrors: true
  });
} catch (error) {
  console.error('Query failed:', error.message);
}

QueryBuilder Errors

// Missing .query() will throw
const builder = JSONPath.create(data);
try {
  await builder.execute();
} catch (error) {
  console.error(error.message);
}

Notes

jsonpathx is JavaScript-only. There is no WASM initialization step; init() is a no-op kept for compatibility.
