#### createLoadHandler(resourceType: string, options: object): nextState
Use it for handle success data loading

Options:
``js
const options = {
mapToKey: bool|string, // default: false, map result to custom reducer key
withLoading: bool, // default: true, enable/disable loading params
singular: bool, // default: false, get first value and store it
withReplace: bool, // default: false, replace current values instead of merge it
addToState: object, // default: {}, additional props passed to state
keepSorting: bool, // default: true, keep data sorting from meta
}
`

##### Simple example
Initial state looks like:
`js
state = {
posts: {
isLoaded: false,
isLoading: false,
posts: {}
}
}
`
`js
const handlers = {
[LOAD_POSTS.SUCCESS]: createLoadHandler('posts')
}
`
Resulted state looks like:
`js
state = {
posts: {
isLoaded: true,
isLoading: false,
posts: [1]
}
}
`

##### Custom example
Initial state looks like:
`js
state = {
posts: {
isLoadedPostIds: false,
isLoadingPostIds: false,
post: null,
}
}
`
Handler:
`js
const handlers = {
[LOAD_POSTS.SUCCESS]: createLoadHandler('posts', { mapToKey: 'post', singular: true })
}
`
Resulted state looks like:
`js
state = {
posts: {
isLoadedPostIds: true,
isLoadingPostIds: false,
postIds: 1,
}
}
`


#### createDeleteHandler(stateKey: string, options: object): nextState
Use it for handle delete data.

Action payload should have deletedId param with singular ID, or deletedIds with array of IDS

##### Simple example
Initial state looks like:
`js
state = {
posts: {
posts: [1, 2]
}
}
`
Handler:
`js
const handlers = {
[DELETE_POST.SUCCESS]: createDeleteHandler('posts')
}
// action.payload.deletedId = 1
`
Resulted state looks like:
`js
state = {
posts: {
posts: [2]
}
}
`

##### Custom key example
Initial state looks like:
`js
state = {
posts: {
postIds: [1, 2]
}
}
`
`js
const handlers = {
[DELETE_POST.SUCCESS]: createDeleteHandler('postIds')
}
// action.payload.deletedId = 2
`
Resulted state looks like:
`js
state = {
posts: {
postIds: [1]
}
}
`

##### Multiple IDs
Initial state looks like:
`js
state = {
posts: {
postIds: [3, 1, 2]
}
}
`
`js
const handlers = {
[DELETE_POST.SUCCESS]: createDeleteHandler('postIds', {
addToState: {
isDeleted: true
}
})
}
// action.payload.deletedIds = [2, 1]
`
Resulted state looks like:
`js
state = {
posts: {
postIds: [3],
isDeleted: true
}
}
`

$3

#### createRelationAddHandler(type: string, relationName: string): nextState
Use it for add relation to data reducer. Inject it to data. reducer

##### Example
Initial state looks like:
`js
state = {
data: {
posts: {
1: {
id: 1,
relationships: {
comments: {
data: [
{
id: 1,
type: 'comments',
},
],
},
},
},
},
}
}
`
Action looks like:
`js
action = {
type: CREATE_COMMENT.SUCCESS,
payload: {
data: {
comments: {
3: {
id: 3,
relationships: {
post: {
data: {
id: 1,
type: 'posts',
},
},
},
},
},
},
},
}
`

Handler:
`js
const handlers = {
[CREATE_COMMENT.SUCCESS]: createRelationAddHandler('comments', 'post')
}
`
Resulted state looks like:
`js
state = {
data: {
posts: {
1: {
id: 1,
relationships: {
comments: {
data: [
{
id: 1,
type: 'comments',
},
{
id: 3,
type: 'comments',
},
],
},
},
},
},
}
}
`

#### createRelationDeleteHandler(relationsName: string): nextState
Use it for delete relation from data reducer. Inject it to data. reducer

##### Example
Initial state looks like:
`js
state = {
data: {
posts: {
1: {
id: 1,
relationships: {
comments: {
data: [
{
id: 1,
type: 'comments',
},
{
id: 3,
type: 'comments',
},
],
},
},
},
},
}
}
`
Action looks like:
`js
action = {
type: DELETE_COMMENT.SUCCESS,
payload: {
deletedId: 3,
relationId: 1,
},
}
`

Handler:
`js
const handlers = {
[DELETE_COMMENT.SUCCESS]: createRelationDeleteHandler('comments')
}
`
Resulted state looks like:
`js
state = {
data: {
posts: {
1: {
id: 1,
relationships: {
comments: {
data: [
{
id: 1,
type: 'comments',
},
],
},
},
},
},
}
}
