> Map `visit` over an array of objects.
|
||||
|
||||
## Install
|
||||
|
||||
Install with [npm](https://www.npmjs.com/):
|
||||
|
||||
```sh
|
||||
$ npm install --save map-visit
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
var mapVisit = require('map-visit');
|
||||
```
|
||||
|
||||
## What does this do?
|
||||
|
||||
**Assign/Merge/Extend vs. Visit**
|
||||
|
||||
Let's say you want to add a `set` method to your application that will:
|
||||
|
||||
* set key-value pairs on a `data` object
|
||||
* extend objects onto the `data` object
|
||||
* extend arrays of objects onto the data object
|
||||
|
||||
**Example using `extend`**
|
||||
|
||||
Here is one way to accomplish this using Lo-Dash's `extend` (comparable to `Object.assign`):
|
||||
|
||||
```js
|
||||
var _ = require('lodash');
|
||||
|
||||
var obj = {
|
||||
data: {},
|
||||
set: function (key, value) {
|
||||
if (Array.isArray(key)) {
|
||||
_.extend.apply(_, [obj.data].concat(key));
|
||||
} else if (typeof key === 'object') {
|
||||
_.extend(obj.data, key);
|
||||
} else {
|
||||
obj.data[key] = value;
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
obj.set('a', 'a');
|
||||
obj.set([{b: 'b'}, {c: 'c'}]);
|
||||
obj.set({d: {e: 'f'}});
|
||||
|
||||
console.log(obj.data);
|
||||
//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }}
|
||||
```
|
||||
|
||||
The above approach works fine for most use cases. However, **if you also want to emit an event** each time a property is added to the `data` object, or you want more control over what happens as the object is extended, a better approach would be to use `visit`.
|
||||
|
||||
**Example using `visit`**
|
||||
|
||||
In this approach:
|
||||
|
||||
* when an array is passed to `set`, the `mapVisit` library calls the `set` method on each object in the array.
|
||||
* when an object is passed, `visit` calls `set` on each property in the object.
|
||||
|
||||
As a result, the `data` event will be emitted every time a property is added to `data` (events are just an example, you can use this approach to perform any necessary logic every time the method is called).
|
||||
|
||||
```js
|
||||
var mapVisit = require('map-visit');
|
||||
var visit = require('object-visit');
|
||||
|
||||
var obj = {
|
||||
data: {},
|
||||
set: function (key, value) {
|
||||
if (Array.isArray(key)) {
|
||||
mapVisit(obj, 'set', key);
|
||||
} else if (typeof key === 'object') {
|
||||
visit(obj, 'set', key);
|
||||
} else {
|
||||
// simulate an event-emitter
|
||||
console.log('emit', key, value);
|
||||
obj.data[key] = value;
|
||||
}
|
||||
}
|
||||
};
|
||||
|
||||
obj.set('a', 'a');
|
||||
obj.set([{b: 'b'}, {c: 'c'}]);
|
||||
obj.set({d: {e: 'f'}});
|
||||
obj.set({g: 'h', i: 'j', k: 'l'});
|
||||
|
||||
console.log(obj.data);
|
||||
//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }, g: 'h', i: 'j', k: 'l'}
|
||||
|
||||
// events would look something like:
|
||||
// emit a a
|
||||
// emit b b
|
||||
// emit c c
|
||||
// emit d { e: 'f' }
|
||||
// emit g h
|
||||
// emit i j
|
||||
// emit k l
|
||||
```
