firebase 错误 TS7006：参数 'snapshot' 隐式具有 'any' 类型

Question

我收到以下 lint 错误：

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

以下 Firebase 云函数：

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

由于您使用的是 TSLint，因此必须为参数 snapshot 和 context 提供类型，如下所示：

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;
  });
