## With Javascript (WebAssembly)
|
||||
|
||||
#### `jsonpath-wasm` 라이브리러
|
||||
|
||||
[Demo]: https://freestrings.github.io/jsonpath/
|
||||
|
||||
**(not yet published `jsonpath-wasm`)**
|
||||
|
||||
*(not yet published `jsonpath-wasm`)**
|
||||
```javascript
|
||||
import * as jsonpath from "jsonpath-wasm";
|
||||
|
||||
//
|
||||
// data
|
||||
//
|
||||
let jsonString = "{\"a\" : 1}";
|
||||
|
||||
//
|
||||
// reuse a compiled jsonpath
|
||||
//
|
||||
let template = jsonpath.compile("$.a");
|
||||
// read as json string
|
||||
template(jsonString)
|
||||
// read as json object
|
||||
template(JSON.parse(jsonString));
|
||||
|
||||
//
|
||||
// reuse a json
|
||||
//
|
||||
|
||||
// as json string
|
||||
let reader1 = jsonpath.reader(jsonString);
|
||||
reader1("$.a");
|
||||
|
||||
// as json object
|
||||
let reader2 = jsonpath.reader(JSON.parse(jsonString));
|
||||
reader2("$.a");
|
||||
|
||||
// read every time
|
||||
jsonpath.read(JSON.parse(jsonString), "$.a");
|
||||
jsonpath.read(jsonString, "$.a");
|
||||
```
|
||||
|
||||
#### `read` 함수
|
||||
|
||||
```
|
||||
jsonpath.read(JSON.parse("{\"a\" : 1}"), "$.a");
|
||||
jsonpath.read("{\"a\" : 1}", "$.a");
|
||||
```
|
||||
|
||||
|
||||
#### JsonPath 재사용
|
||||
|
||||
```
|
||||
let template = jsonpath.compile("$.a");
|
||||
|
||||
//
|
||||
// 1. read json string
|
||||
//
|
||||
template("{\"a\" : 1}")
|
||||
|
||||
//
|
||||
// 2. read as json object
|
||||
//
|
||||
template(JSON.parse("{\"a\" : 1}"));
|
||||
```
|
||||
|
||||
#### Json 재사용
|
||||
|
||||
```
|
||||
//
|
||||
// 1. read json string
|
||||
//
|
||||
let reader1 = jsonpath.reader("{\"a\" : 1}");
|
||||
reader1("$.a");
|
||||
reader1("$.b");
|
||||
|
||||
//
|
||||
// 2. read as json object
|
||||
//
|
||||
let reader2 = jsonpath.reader(JSON.parse("{\"a\" : 1}"));
|
||||
reader2("$.a");
|
||||
reader2("$.b");
|
||||
```
