使用 RTDB

¥useRTDB

反应式 Firebase 实时数据库 结合。使本地数据始终与远程数据库保持同步变得简单。

¥Reactive Firebase Realtime Database binding. Making it straightforward to always keep your local data in sync with remotes databases. Available in the @vueuse/firebase add-on.

用法

¥Usage

import { initializeApp } from 'firebase/app'
import { getDatabase } from 'firebase/database'
import { useRTDB } from '@vueuse/firebase/useRTDB'

const app = initializeApp({ /* config */ })
const db = getDatabase(app)

// in setup()
const todos = useRTDB(db.ref('todos'))

你可以通过传递 autoDispose: false 来重用数据库引用

¥You can reuse the db reference by passing autoDispose: false

const todos = useRTDB(db.ref('todos'), { autoDispose: false })

或使用核心包中的 createGlobalState

¥or use createGlobalState from the core package

// store.js
import { createGlobalState } from '@vueuse/core'
import { useRTDB } from '@vueuse/firebase/useRTDB'

export const useTodos = createGlobalState(
  () => useRTDB(db.ref('todos')),
)

// app.js
import { useTodos } from './store'

const todos = useTodos()

类型声明

export interface UseRTDBOptions {
  errorHandler?: (err: Error) => void
  autoDispose?: boolean
}
/**
 * Reactive Firebase Realtime Database binding.
 *
 * @see https://vueuse.org/useRTDB
 */
export declare function useRTDB<T = any>(
  docRef: DatabaseReference,
  options?: UseRTDBOptions,
): Ref<T | undefined>
