# jsonpath-rs
JsonPath engine for NodeJs with Rust native implementation.
[![Build Status](https://travis-ci.org/freestrings/jsonpath.svg?branch=master)](https://travis-ci.org/freestrings/jsonpath)
It is [JsonPath](https://goessner.net/articles/JsonPath/) implementation. The core implementation is written in Rust-lang.

### jsonpath.select(json: string|object, jsonpath: string)
```javascript
let jsonObj = {
"school": {
"friends": [{"id": 0}, {"id": 1}]
},
"friends": [{"id": 0}, {"id": 1}]
};
let ret = [{"id": 0}, {"id": 0}];
let a = jsonpath.select(JSON.stringify(jsonObj), "$..friends[0]");
let b = jsonpath.select(jsonObj, "$..friends[0]");
console.log(
JSON.stringify(ret) == JSON.stringify(a),
JSON.stringify(a) == JSON.stringify(b)
);
```
### jsonpath.compile(jsonpath: string)
```javascript
let template = jsonpath.compile("$..friends[0]");
let jsonObj = {
"school": {
"friends": [ {"id": 0}, {"id": 1} ]
},
"friends": [ {"id": 0}, {"id": 1} ]
};
let ret = JSON.stringify([ {"id": 0}, {"id": 0} ]);
// 1. read as json object
console.log(JSON.stringify(template(jsonObj)) == ret);
// 2. read as json string
console.log(JSON.stringify(template(JSON.stringify(jsonObj))) == ret);
let jsonObj2 = {
"school": {
"friends": [
{"name": "Millicent Norman"},
{"name": "Vincent Cannon"}
]
},
"friends": [ {"id": 0}, {"id": 1} ]
};
let ret2 = JSON.stringify([ {"id": 0}, {"name": "Millicent Norman"} ]);
// 1. read as json object
console.log(JSON.stringify(template(jsonObj2)) == ret2);
// 2. read as json string
console.log(JSON.stringify(template(JSON.stringify(jsonObj2))) == ret2);
```
### jsonpath.selector(json: string|object)
```javascript
let jsonObj = {
"school": {
"friends": [{"id": 0}, {"id": 1}]
},
"friends": [{"id": 0},{"id": 1}]
};
let ret1 = JSON.stringify([ {"id": 0}, {"id": 0} ]);
let ret2 = JSON.stringify([ {"id": 1}, {"id": 1} ]);
// 1. read as json object
let selector = jsonpath.selector(jsonObj);
console.log(JSON.stringify(selector("$..friends[0]")) == ret1);
console.log(JSON.stringify(selector("$..friends[1]")) == ret2);
// 2. read as json string
let selector = jsonpath.selector(JSON.stringify(jsonObj));
console.log(JSON.stringify(selector("$..friends[0]")) == ret1);
console.log(JSON.stringify(selector("$..friends[1]")) == ret2);
```
