npm install copy-to
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
copy(src).to(des);
|
|
copy(src).toCover(des);
|
|
copy(src).override(des);
|
|
|
|
copy(src).pick('proName1', 'proName2').to(des);
|
|
copy(src).pick('proName1', 'proName2').toCover(des);
|
|
copy(src).pick('proName1', 'proName2').override(des);
|
|
|
|
copy(src).and(other).to(des);
|
|
copy(src).and(other).toCover(des);
|
|
copy(src).and(second).and(third).to(des);
|
|
|
|
copy(src).and(other).pick('proName1', 'proName2').to(des);
|
|
copy(src).and(other).pick('proName1', 'proName2').toCover(des);
|
|
copy(src).and(second).and(third).pick('proName1', 'proName2').to(des);
|
|
```

It won't copy access(getter / setter) by default, if you want to copy them, please use:
|
|
|
|
```js
|
|
copy(src).withAccess().and(other).to(des);
|
|
```
|
|
|
|
## Example
|
|
|
|
```js
|
|
var copy = require('copy-to');
|
|
|
|
var src = {
|
|
_name: 'foo',
|
|
set name(val) {
|
|
this._name = val;
|
|
},
|
|
get name() {
|
|
return this._name;
|
|
},
|
|
show: function () {
|
|
console.log(this._name);
|
|
}
|
|
};
|
|
|
|
var des = {
|
|
_name: 'bar'
|
|
};
|
|
|
|
copy(src).to(des);
|
|
copy(src).toCover(des);
|
|
copy(src).pick('_name', 'name').to(des);
|
|
copy(src).pick('_name', 'name').toCover(des);
|
|
```
