Resting Ducks

REST conventions for single tree stores.

Installation

npm install resting-ducks --save

Example

import { Duck, Api} from 'resting-ducks'
 
const client = new Api({host: 'http://localhost:8000', resource: 'tasks'})
const tasks = Duck(client, {})('myTasks')
const store = createStore(tasks.reducer)
 
store.dispatch(
  task.create({id: 10, name: 'Clean the windows', resolved: false})
).then(() => {
  task.update({resolved: true}, 10, {patch: true})
})

Immutable

The state is stored using immutable.js

API

Duck

The constructor accepts two arguments:

• client an API to interact with your server. You can use the one provided by default in resting-ducks wich uses fetch-please for promise and canceleable requests.
• options
  • indexes An array of attributes you would like your model indexed by. Defaults to ['id']

import { Duck, Api} from 'resting-ducks'
 
const client = new Api({host: 'http://localhost:8000', resource: 'tasks'})
const tasks = Duck(client, {
  indexes: ['id', 'project_id']
})('myTasks')
const store = createStore(tasks.reducer)

Api

Defines how you interact with your server. Must implement fetch, post, put, and del.

Options:

• host Mandatory. The host of your server
• resource Mandatory. The name of your resource
• base Defaults to /. The prefix (for instance versioning) of your API

import { Api } from 'resting-ducks'
 
const client = new Api({
  host: 'http://localhost:3000',
  resource: 'users',
  base: '/v2'
})
 
const {xhr, promise} = client.fetch()
 
promise.then((data) => {
  console.log(data)
})
 
// Timeout of 500ms
setTimeout(() => {
  xhr.abort()
}, 500)

Duck API

Resting ducks come with all the common REST actions so you don't have to re-implement them over and over in your stores.

Reducer

reducer(state, action)

The reducer for your resource. Add this one to your store and you are all set!

Actions creators

set(resources, id|cid = null)

Replace the current resources with the given ones.

If a id/cid is given, it applies only to the given resource

patch(attributes, id|cid)

Patch the resource with the given attributes.

request({label, xhr}, id|cid = null)

Marks the current duck as having an ongoing cancelable request. You can use this to represent a loading transaction and cancel it if needed.

If a id/cid is given, it applies only to the given resource

error({label, error}, id|cid = null)

Marks the current duck as having an error. You can use this to represent it.

If a id/cid is given, it applies only to the given resource.

add(attributes)

Append a new resource on the duck.

remove(id|cid)

Remove a resource.

fetch()

Retrieve your models from your server.

It marks the request object so you can track progress and cancel it if needed.

In case of error it marks the error object.

create(attributes, options)

Send a new resource to your server. The new resource is optimistically added on the client.

It marks the request object so you can track progress and cancel it if needed.

In case of error it marks the error object.

udpate(attributes, id, options)

Send new attributes for your resource to your server. The new attributes are optimistically set on the client.

It marks the request object so you can track progress and cancel it if needed.

In case of error it marks the error object.

Extra options:

• patch: Wether the attributes are a patch or a full representation of the resource. Defaults to false.

TODO Add support for PATCH

destroy(id, options)

Destroy a resource on your server. The resource is optimistically removed on the client.

It marks the request object so you can track progress and cancel it if needed.

In case of error it marks the error object.

Options

create, update and destroy are optimistic by default. You can disable that behaviour passing the optimistic flag to false.

Tree schema

Your tree will have the following schema:

resources: [
  {                    // Information at the resource level
    cid: String,       // Client side id. Used for optimistic updates
    request: {         // An ongoing request
      label: String,   // Examples: 'updating', 'creating', 'fetching', 'destroying' ...
      xhr: Object,     // The xhr object. You can abort it with `xhr.abort()`
    },
    error: {           // A failed request
      label: String,   // Examples: 'updating', 'creating', 'fetching', 'destroying' ...
      error: String,   // A string representing the error
    },
    attributes: Object // The resource attributes
  }
]                      // Information at the collection level
cid: String,           // The latest Client id generated
request: {             // An ongoing request
  label: String,       // Examples: 'updating', 'creating', 'fetching', 'destroying' ...
  xhr: Object,         // The xhr object. You can abort it with `xhr.abort()`
},
error: {               // A failed request
  label: String,       // Examples: 'updating', 'creating', 'fetching', 'destroying' ...
  error: Object,       // A string representing the error
}
