Build Status Coverage Status Dependency Status devDependency Status

NPM

This plugin provides simple methods to add, find, update and remove data.

Usage

Initialisation

var db = new PouchDB('dbname')
var api = db.hoodieApi()

API

// Options 
// emitter: Optionally pass an instance of EventEmitter for hoodieApi to use 
 
var db = new PouchDB('dbname')
var api = db.hoodieApi({
  emitter: existingEventEmitter
})
 
// all methods return promises 
api.add(object)
api.add([object1, id2])
api.find(id)
api.find(object) // with id property 
api.find([object1, id2])
api.findOrAdd(id, object)
api.findOrAdd(object)
api.findOrAdd([object1, object2])
api.findAll()
api.findAll(filterFunction)
api.update(id, changedProperties)
api.update(id, updateFunction)
api.update(object)
api.update([object1, object2])
api.updateOrAdd(id, object)
api.updateOrAdd(object)
api.updateOrAdd([object1, object2])
api.updateAll(changedProperties)
api.updateAll(updateFunction)
api.remove(id)
api.remove(object)
api.remove([object1, id2])
api.removeAll()
api.removeAll(filterFunction)
api.clear()
 
// events 
// Important: the order of when the methods promises resolve and the events get 
//            triggered cannot be guaranteed as we rely on PouchDB’s .changes(). 
//            We would love to enforce promises to resolve after changes get 
//            emitted, but the required complexity to do that is not worth it. 
api.on('add', function(object, options) {})
api.on('update', function(object, options) {})
api.on('remove', function(object, options) {})
api.on('change', function(eventName, object, options) {})
api.on('clear', function() {})
api.one(eventName, eventHandlerFunction)
api.off(eventName, eventHandlerFunction)
 
// returns an API with all methods above, but implicitly scoped to the passed 
// id prefix. Meaning events are only triggered for documents that match the id 
// prefix, and documents are not found unless they have the id prefix. 
// See https://github.com/hoodiehq/discussion/issues/106 for more context. 
var todoStore = api.withIdPrefix('todo/')
todoStore.on('change', renderTodoList)
todoStore.add({text: 'Remember the milk!'})
 
// original PouchDB (http://pouchdb.com/api.html) instance used for the store 
api.db
