firebase 错误 TS7006：参数“快照”隐式具有“任何”类型

Question

我收到以下 lint 错误：

error TS7006: Parameter 'snapshot' implicitly has an 'any' type.

在以下 Firebase 云功能上：

exports.createTeamMember = functions.firestore
  .document(`teamProfile/{teamId}/teamMemberList/{newUserId}`)
  .onCreate(async (snapshot, context) => {
    const id: string = snapshot.data().id;
    const email: string = snapshot.data().email;
    const teamId: string = snapshot.data().teamId;
  });

Answer 1

由于您使用TSLint，必须为参数提供类型snapshot和context如下：

import * as admin from 'firebase-admin';
import { EventContext } from 'firebase-functions';

exports.createTeamMember = functions.firestore
  .document(`teamProfile/{teamId}/teamMemberList/{newUserId}`)
  .onCreate(async (snapshot: admin.firestore.DocumentSnapshot, context: EventContext) => {
    const id: string = snapshot.data().id;
    const email: string = snapshot.data().email;
    const teamId: string = snapshot.data().teamId;
  });
