Store

A store is created with doura(). It owns named model instances, plugins, and query defaults.

import { defineModel, doura } from 'doura'

const counterModel = defineModel({
  name: 'counter',
  state: { count: 0 },
  actions: {
    increment() {
      this.count += 1
    },
  },
})

const store = doura()
const counter = store.getModel(counterModel)

counter.increment()
console.log(counter.count) // 1

Options

const store = doura({
  initialState: {
    counter: { count: 100 },
  },
  plugins: [[myPlugin, options]],
  query: {
    staleTime: 10_000,
    gcTime: 300_000,
  },
})

• initialState is keyed by model name and applies when a named model is first created.
• plugins is an array of [plugin, options?] tuples.
• query sets store-wide defaults for query cache staleness and garbage collection.

API

Method	Description
getModel(model)	Get or create a named model instance. The instance is cached by model.$options.name.
getDetachedModel(model)	Create an independent model instance that is not cached and is not included in getState().
getState()	Return a snapshot of all named models' state, keyed by model name.
subscribe(fn)	Listen to any named model state change. Returns an unsubscribe function.
destroy()	Destroy model instances, plugin hooks, subscribers, and query coordination.

Multiple Stores

The same model definition can be used in multiple stores. Each store has independent state.

const storeA = doura()
const storeB = doura()

const counterA = storeA.getModel(counterModel)
const counterB = storeB.getModel(counterModel)

counterA.increment()

console.log(counterA.count) // 1
console.log(counterB.count) // 0
