awa*_*iat 1 javascript firebase-authentication google-cloud-firestore
我尝试开始使用 Firebase 9。我使用 VSCode 并使用 npm 导出（在 vscode 中）
<script src="https://www.gstatic.com/firebasejs/9.0.0-beta.5/firebase-app-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.0-beta.5/firebase-analytics-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.0-beta.5/firebase-auth-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.0-beta.5/firebase-firestore-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.0-beta.5/firebase-storage-compat.js"></script>
<!-- init -->
<script defer src="firebase/init.js" type="text/javascript"></script>
<script type="module">
import {
getAuth,
onAuthStateChanged
} from "firebase/auth";
const auth = getAuth(firebaseApp);
onAuthStateChanged(auth, user => {
console.log(user)
});
</script>
错误
未捕获的类型错误：无法解析模块说明符“firebase/auth”。相对引用必须以“/”、“./”或“../”开头。
我遇到了同样的问题，并通过仔细观看 David在 5:40 时间戳左右的视频来解决它。
这是在本地服务时有效的基本样板：
import { initializeApp } from 'https://www.gstatic.com/firebasejs/9.0.0/firebase-app.js';
import { getAuth, onAuthStateChanged } from 'https://www.gstatic.com/firebasejs/9.0.0/firebase-auth.js';
const firebaseApp = initializeApp({
// (insert your Firebase configuration here)
});
const auth = getAuth(firebaseApp);
onAuthStateChanged(auth, user => {
if (user) {
console.log('Logged in as ${user.email}' );
} else {
console.log('No user');
}
});
