# lodash-id [![Build Status](https://travis-ci.org/typicode/lodash-id.svg)](https://travis-ci.org/typicode/lodash-id) [![NPM version](https://badge.fury.io/js/lodash-id.svg)](http://badge.fury.io/js/lodash-id)
> `lodash-id` makes it easy to manipulate id-based resources with [lodash](https://lodash.com/) or [lowdb](https://github.com/typicode/lowdb)
* `getById`
* `insert`
* `upsert`
* `updateById`
* `updateWhere`
* `replaceById`
* `removeById`
* `removeWhere`
* `createId`
## Install
```bash
# with lodash
npm install lodash lodash-id --save
# with lowdb
npm install lowdb lodash-id --save
```
__Note__ `lodash-id` is also compatible with [underscore](http://underscorejs.org/)
## API
In the API examples, we're assuming `db` to be:
```js
const db = {
posts: [
{id: 1, body: 'one', published: false},
{id: 2, body: 'two', published: true}
],
comments: [
{id: 1, body: 'foo', postId: 1},
{id: 2, body: 'bar', postId: 2}
]
}
```
__getById(collection, id)__
Finds and returns document by id or undefined.
```js
const post = _.getById(db.posts, 1)
```
__insert(collection, document)__
Adds document to collection, sets an id and returns created document.
```js
const post = _.insert(db.posts, { body: 'New post' })
```
If the document already has an id, and it is the same as an existing document in the collection, an error is thrown.
```js
_.insert(db.posts, { id: 1, body: 'New post' })
_.insert(db.posts, { id: 1, title: 'New title' }) // Throws an error
```
__upsert(collection, document)__
Adds document to collection, sets an id and returns created document.
```js
const post = _.upsert(db.posts, { body: 'New post' })
```
If the document already has an id, it will be used to insert or replace.
```js
_.upsert(db.posts, { id: 1, body: 'New post' })
_.upsert(db.posts, { id: 1, title: 'New title' })
_.getById(db.posts, 1) // { id: 1, title: 'New title' }
```
__updateById(collection, id, attrs)__
Finds document by id, copies properties to it and returns updated document or undefined.
```js
const post = _.updateById(db.posts, 1, { body: 'Updated body' })
```
__updateWhere(collection, whereAttrs, attrs)__
Finds documents using `_.where`, updates documents and returns updated documents or an empty array.
```js
// Publish all unpublished posts
const posts = _.updateWhere(db.posts, { published: false }, { published: true })
```
__replaceById(collection, id, attrs)__
Finds document by id, replaces properties and returns document or undefined.
```js
const post = _.replaceById(db.posts, 1, { foo: 'bar' })
```
__removeById(collection, id)__
Removes document from collection and returns it or undefined.
```js
const comment = _.removeById(db.comments, 1)
```
__removeWhere(collection, whereAttrs)__
Removes documents from collection using `_.where` and returns removed documents or an empty array.
```js
const comments = _.removeWhere(db.comments, { postId: 1 })
```
__id__
Overwrite it if you want to use another id property.
```js
_.id = '_id'
```
__createId(collectionName, doc)__
Called by lodash-id when a document is inserted. Overwrite it if you want to change id generation algorithm.
```js
_.createId = (collectionName, item) => `${collectionName}-${item.prop}-${Date.now()}`
```
