### about
handle json data with safe & easy way

### why
Modern web frameworks, such as React and Vue, mostly render based on JSON data.

Ideally, as long as the back-end and front-end render web pages according to the agreed JSON data type, there will be no errors.
However, in the real world, in the mode of agile development, or because of later business adjustments, or changes in personnel, some data types change. At this time, new risks are introduced, such as a white screen and a webpage crash. At this time, if you spend a lot of time and energy to troubleshoot this type of error, it is not conducive to business adjustment and bug follow-up.

It is better to deal with it at the beginning, so as to avoid the problem that the web page crashes and cannot be rendered because of the change of JSON data type.

### install
```
npm install js-safe-json
```

### dev
```
npm run start
```

### run test
```
npm run test
```

### usage
```
import {
  fetchObject,
  fetchBoolean,
  fetchString,
  fetchNumber,
  fetchArray } from 'js-safe-json';

// your json data
let jsonData = {
  a: [
    {
      a1: '',
      a2: true,
      a3: false,
    },
    {
      a1: [1, 2, 3, 4],
      a2: true,
      a3: false,
    },
  ],
  b: {
    b1: 12,
    b2: 12.0,
    b3: 12.01,
    b4: 12.001
  },
  c: 0,
  d: null,
  e: '0'
};

// it is safe,if data not expect value,it will return default value
// object  default value: {}
// boolean default value: false
// string  default value: ''
// number  default value: 0
// array   default value: []

let object = fetchObject(jsonData, 'b');
let boolean = fetchBoolean(jsonData, 'b');
let string = fetchString(jsonData, 'e');
let number = fetchNumber(jsonData, 'b', 'b1');
let array = fetchArray(jsonData, 'a');
```
