Set

This page discusses how set works.

onDiconnect's set works in the same way.

Type Checks

RTDB set does not have weird quirks like Firestore, so the type check is straight forward:

import {
    MetaTypeCreator,
    ServerTimestamp,
    NumericKeyRecord,
    Removable,
    createRef,
    set,
    serverTimestamp,
    getDatabase,
} from 'firesagejs'

export type Example = MetaTypeCreator<{
    b:
        | {
                c: boolean | Removable
                d: {
                    e: ServerTimestamp
                }
          }
        | Removable
    f: Record<string, 'a' | 'b' | 'c'>
    i: NumericKeyRecord<boolean>
}>

const exampleRef = createRef<Example>(getDatabase())

;async () => {
    await set(exampleRef('b/d'), { e: serverTimestamp() }) // ok
    await set(exampleRef('b/d/e'), serverTimestamp()) // ok
    await set(exampleRef('f'), { xyz: 'a' }) // ok
    await set(exampleRef('f/xyz'), 'b') // ok
    await set(exampleRef('i'), { 123: false }) // ok
    await set(exampleRef('i/123'), false) // ok

    await set(exampleRef('b/d/e'), 'incorrect value') // not ok, incorrect value
    await set(exampleRef('f'), { 123: 'a' }) // not ok, expect the key to be non-numeric string
    await set(exampleRef('f/123'), 'b') // not ok, expect the key to be non-numeric string
    await set(exampleRef('i'), { abc: false }) // not ok, expect the key to be numeric string
    await set(exampleRef('i/abc'), false) // not ok, expect the key to be numeric string
}
