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
js
import { useRTDB } from '@vueuse/firebase/useRTDB'
import { initializeApp } from 'firebase/app'
import { getDatabase } from 'firebase/database'
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
ts
const todos = useRTDB(db.ref('todos'), { autoDispose: false })
或使用核心包中的 createGlobalState
¥or use createGlobalState
from the core package
js
// store.js
import { createGlobalState } from '@vueuse/core'
import { useRTDB } from '@vueuse/firebase/useRTDB'
export const useTodos = createGlobalState(
() => useRTDB(db.ref('todos')),
)
js
// app.js
import { useTodos } from './store'
const todos = useTodos()
类型声明
typescript
export interface UseRTDBOptions {
errorHandler?: (err: Error) => void
autoDispose?: boolean
}
/**

export declare function useRTDB<T = any>(
docRef: DatabaseReference,
options?: UseRTDBOptions,
): Ref<T | undefined, T | undefined>
