This package will help parse OData strings (only the Microsoft Dataverse subset). It can be used as a validator, or you can build some javascript library which consumes the output of this library.

import { isGuid } from './validators/isGuid';
import { recognizedGuid } from './validators/recognizedGuid';

/**
 * Parses the {@link ODataSavedQuery.savedQuery savedQuery} or
 * {@link ODataUserQuery.userQuery userQuery} query
 * @returns Returns `false` when the parse has an error
 */
export const getXQueryFromParser = (X, parser, result) => {
  const value = parser.getAll(X);
  if (value.length === 0) {
    return true;
  }
  if (!recognizedGuid(value, result) || !isGuid(value, result)) {
    return false;
  }
  result[X] = value[0];
  return true;
