# Json Function

Json-Function provides a lot of useful functions especially for your json data. It contains the methods you need too much to eliminate unnecessary code repetition.

You can use the Json-Function methods separately, but it is possible to use them all together. You can also chain it.

[Github](https://github.com/aykutkardas/Json-Function) repository for your stars.

## Usage

#### Install

```bash
$ npm install json-function
```

#### Import

```javascript
import JsonFunction from 'json-function';
```

#### Usage

Example Data

```javascript
const data = [
  {
    userId: 1,
    id: 1,
    title: "delectus aut autem",
    completed: false
  },
  {
    userId: 1,
    id: 2,
    title: "quis ut nam facilis et officia qui",
    completed: false
  },
  {
    userId: 1,
    id: 3,
    title: "fugiat veniam minus",
    completed: false
  },
  {
    userId: 1,
    id: 4,
    title: "et porro tempora",
    completed: true
  }
];
```

Chaining Syntax

```javascript

JsonFunction
  .where({ completed: false })
  .select(["title", "completed"])
  .orderBy("title", "DESC")
  .limit(2)
  .get(data);
```

Output

```javascript
[
  {
    title: "quis ut nam facilis et officia qui",
    completed: false
  },
  {
    title: "fugiat veniam minus",
    completed: false
  }
];
```

Basic Syntax

```javascript
JsonFunction.where({ completed: false });
JsonFunction.select(["title", "completed"]);
JsonFunction.orderBy("title", "DESC");
JsonFunction.limit(2);
const result = JsonFunction.get(data);
```

###  getQuery

Create a query and use it at any time.

```javascript
const queryTwoIncompleteTasks = JsonFunction
  .where({ completed: false })
  .select(["title", "completed"])
  .limit(2)
  .getQuery();
```

### setQuery

```javascript
JsonFunction.setQuery(queryTwoIncompleteTasks).get(data);
```

or

```javascript
JsonFunction.get(data, { query: queryTwoIncompleteTasks });
```
