javascript - 火力地堡错误 TS7006 : Parameter 'snapshot' implicitly has an 'any' type

Question

我收到以下 lint 错误:

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

关于以下 Firebase 云功能:

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;
  });
