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 { getTopFromParser } from './getTopFromParser';
import { getSelectFromParser } from './getSelectFromParser';
import { getExpandFromParser } from './getExpandFromParser';
import { getFetchXmlFromParser } from './getFetchXmlFromParser';
import { getXQueryFromParser } from './getXQueryFromParser';
import { getOrderByFromParser } from './getOrderByFromParser';

/**
 * parses the OData query and applies some Dataverse validations
 * @param query The OData query
 * @returns The parsed OData query
 */
export const parseOData = query => {
  const parser = new URLSearchParams(query);
  const result = {};
  getExpandFromParser(parser, result) && getSelectFromParser(parser, result) && getTopFromParser(parser, result) && getFetchXmlFromParser(parser, result) && getXQueryFromParser('savedQuery', parser, result) && getXQueryFromParser('userQuery', parser, result) && getOrderByFromParser(parser, result);
  return result;
