You can verify these findings by [running the project yourself](https://github.com/andykais/json-querying-performance-testing#how-to-run) and adding more perf cases.\n\n## Install\n\n```shell\nnpm install jsonpath-plus\n```\n\n## Setup\n\n### Node.js\n\n```js\nconst {JSONPath} = require('jsonpath-plus');\n\nconst result = JSONPath({path: '...', json});\n```\n\n### Browser\n\nFor browser usage you can directly include `dist/index-browser-umd.cjs`; no\nBrowserify magic is necessary:\n\n```html\n<!-- Polyfill recommended by Babel for items not covered for older\n browsers in dist -->\n<script src=\"node_modules/core-js-bundle/minified.js\"></script>\n\n<script src=\"node_modules/jsonpath-plus/dist/index-browser-umd.cjs\"></script>\n\n<script>\n\nconst result = JSONPath.JSONPath({path: '...', json: {}});\n\n</script>\n```\n\n### ESM (Modern browsers)\n\nYou may also use ES6 Module imports (for modern browsers):\n\n```html\n<script type=\"module\">\n\nimport {\n JSONPath\n} from './node_modules/jsonpath-plus/dist/index-browser-esm.js';\n\nconst result = JSONPath({path: '...', json: {}});\n\n</script>\n```\n\n### ESM (Bundlers)\n\nOr if you are bundling your JavaScript (e.g., with Rollup), just use,\nnoting that [`mainFields`](https://github.com/rollup/plugins/tree/master/packages/node-resolve#mainfields)\nshould include `browser` for browser builds (for Node, the default, which\nchecks `module`, should be fine):\n\n```js\nimport {JSONPath} from 'jsonpath-plus';\n\nconst result = JSONPath({path: '...', json});\n```\n\n## Usage\n\nThe full signature available is:\n\n```\nconst result = JSONPath([options,] path, json, callback, otherTypeCallback);\n```\n\nThe arguments `path`, `json`, `callback`, and `otherTypeCallback`\ncan alternatively be expressed (along with any other of the\navailable properties) on `options`.\n\nNote that `result` will contain all items found (optionally\nwrapped into an array) whereas `callback` can be used if you\nwish to perform some operation as each item is discovered, with\nthe callback function being executed 0 to N times depending\non the number of independent items to be found in the result.\nSee the docs below for more on `JSONPath`'s available arguments.\n\nSee also the [API docs](https://jsonpath-plus.github.io/JSONPath/docs/ts/).\n\n### Properties\n\nThe properties that can be supplied on the options object or\nevaluate method (as the first argument) include:\n\n- ***path*** (**required**) - The JSONPath expression as a (normalized\n or unnormalized) string or array\n- ***json*** (**required**) - The JSON object to evaluate (whether of\n null, boolean, number, string, object, or array type).\n- ***autostart*** (**default: true**) - If this is supplied as `false`,\n one may call the `evaluate` method manually.\n- ***flatten*** (**default: false**) - Whether the returned array of results\n will be flattened to a single dimension array.\n- ***resultType*** (**default: \"value\"**) - Can be case-insensitive form of\n \"value\", \"path\", \"pointer\", \"parent\", or \"parentProperty\" to determine\n respectively whether to return results as the values of the found items,\n as their absolute paths, as [JSON Pointers](https://tools.ietf.org/html/rfc6901)\n to the absolute paths, as their parent objects, or as their parent's\n property name. If set to \"all\", all of these types will be returned on\n an object with the type as key name.\n- ***sandbox*** (**default: {}**) - Key-value map of variables to be\n available to code evaluations such as filtering expressions. (Note\n that the current path and value will also be available to those\n expressions; see the Syntax section for details.)\n- ***wrap*** (**default: true**) - Whether or not to wrap the results\n in an array. If `wrap` is set to `false`, and no results are found,\n `undefined` will be returned (as opposed to an empty array when\n `wrap` is set to true). If `wrap` is set to `false` and a single\n non-array result is found, that result will be the only item returned\n (not within an array). An array will still be returned if multiple\n results are found, however. To avoid ambiguities (in the case where\n it is necessary to distinguish between a result which is a failure\n and one which is an empty array), it is recommended to switch the\n default to `false`.\n- ***preventEval*** (**default: false**) - Although JavaScript evaluation\n expressions are allowed by default, for security reasons (if one is\n operating on untrusted user input, for example), one may wish to\n set this option to `true` to throw exceptions when these expressions\n are attempted.\n- ***parent*** (**default: null**) - In the event that a query could be\n made to return the root node, this allows the parent of that root node\n to be returned within results.\n- ***parentProperty*** (**default: null**) - In the event that a query\n could be made to return the root node, this allows the `parentProperty`\n of that root node to be returned within results.\n- ***callback*** (**default: (none)**) - If supplied, a callback will be\n called immediately upon retrieval of an end point value. The three arguments\n supplied will be the value of the payload (according to `resultType`),\n the type of the payload (whether it is a normal \"value\" or a \"property\"\n name), and a full payload object (with all `resultType`s).\n- ***otherTypeCallback*** (**default: \\<A function that throws an error**\n **when @other() is encountered\\>**) - In the current absence of JSON\n Schema support, one can determine types beyond the built-in types by\n adding the operator `@other()` at the end of one's query. If such a\n path is encountered, the `otherTypeCallback` will be invoked with the\n value of the item, its path, its parent, and its parent's property name,\n and it should return a boolean indicating whether the supplied value\n belongs to the \"other\" type or not (or it may handle transformations and\n return false).\n\n### Instance methods\n\n- ***evaluate(path, json, callback, otherTypeCallback)*** OR\n ***evaluate({path: \\<path\\>, json: \\<json object\\>, callback:***\n ***\\<callback function\\>, otherTypeCallback:***\n ***\\<otherTypeCallback function\\>})*** - This method is only\n necessary if the `autostart` property is set to `false`. It\n can be used for repeated evaluations using the same configuration.\n Besides the listed properties, the latter method pattern can\n accept any of the other allowed instance properties (except\n for `autostart` which would have no relevance here).\n\n### Class properties and methods\n\n- ***JSONPath.cache*** - Exposes the cache object for those who wish\n to preserve and reuse it for optimization purposes.\n- ***JSONPath.toPathArray(pathAsString)*** - Accepts a normalized or\n unnormalized path as string and converts to an array: for\n example, `['$', 'aProperty', 'anotherProperty']`.\n- ***JSONPath.toPathString(pathAsArray)*** - Accepts a path array and\n converts to a normalized path string. The string will be in a form\n like: `$['aProperty']['anotherProperty][0]`. The JSONPath terminal\n constructions `~` and `^` and type operators like `@string()` are\n silently stripped.\n- ***JSONPath.toPointer(pathAsArray)*** - Accepts a path array and\n converts to a [JSON Pointer](https://tools.ietf.org/html/rfc6901).\n The string will be in a form like: `/aProperty/anotherProperty/0`\n (with any `~` and `/` internal characters escaped as per the JSON\n Pointer spec). The JSONPath terminal constructions `~` and `^` and\n type operators like `@string()` are silently stripped.\n\n## Syntax through examples\n\nGiven the following JSON, taken from <http://goessner.net/articles/JsonPath/>:\n\n```json\n{\n\"store\": {\n \"book\": [\n {\n \"category\": \"reference\",\n \"author\": \"Nigel Rees\",\n \"title\": \"Sayings of the Century\",\n \"price\": 8.95\n },\n {\n \"category\": \"fiction\",\n \"author\": \"Evelyn Waugh\",\n \"title\": \"Sword of Honour\",\n \"price\": 12.99\n },\n {\n \"category\": \"fiction\",\n \"author\": \"Herman Melville\",\n \"title\": \"Moby Dick\",\n \"isbn\": \"0-553-21311-3\",\n \"price\": 8.99\n },\n {\n \"category\": \"fiction\",\n \"author\": \"J.

In JSONPath, a filter expression, in addition to its `@` being a\nreference to its children, actually selects the immediate children\nas well, whereas in XPath, filter conditions do not select the children\nbut delimit which of its parent nodes will be obtained in the result.\n1. In JSONPath, array indexes are, as in JavaScript, 0-based (they begin\nfrom 0), whereas in XPath, they are 1-based.\n1. In JSONPath, equality tests utilize (as per JavaScript) multiple equal signs\nwhereas in XPath, they use a single equal sign.\n\n## Ideas\n\n1. Support OR outside of filters (as in XPath `|`) and grouping.\n1. Create syntax to work like XPath filters in not selecting children?\n1. Allow option for parentNode equivalent (maintaining entire chain of\n parent-and-parentProperty objects up to root)\n\n## Development\n\nRunning the tests on Node:\n\n```shell\nnpm test\n```\n\nFor in-browser tests:\n\n- Serve the js/html files:\n\n```shell\nnpm run browser-test\n```\n\n- Visit [http://localhost:8082/test/](http://localhost:8082/test/).\n\n## License\n\n[MIT License](http://www.opensource.org/licenses/mit-license.php).\n" | ||
