As a newcomer to Vue, I decided to tackle my second tutorial which involved integrating Firebase backend with Vue. However, the tutorial was based on Vue 2 and an older version of Firebase. Determined to stay current, I set out to replicate the project using Vue 3 and the latest Firebase version.
I soon discovered that resources for Firebase 9.0.1 were somewhat scarce when it came to integrating with Vue. While browsing through the Firebase documentation, I stumbled upon the signInAnonymously method:
import { getAuth, signInAnonymously } from "firebase/auth";
const auth = getAuth();
signInAnonymously(auth)
.then(() => {
// Signed in..
})
.catch((error) => {
const errorCode = error.code;
const errorMessage = error.message;
// ...
});
It appeared that Firebase 9.0.1 followed an "import only what you use" approach. To utilize the getAuth and signInAnonymously methods from firebase/auth, one would typically write:
import { getAuth, signInAnonymously } from 'firebase/auth';
However, I encountered some confusion while attempting to implement these methods in my .Vue file. After experimenting in my firebase.js file, I settled on the following export setup:
export const auth = getAuth();
export {signInAnonymously};
Within my Login.vue file, I structured the imports and data/methods declarations as follows:
import { auth, signInAnonymously } from '../firebase'
export default {
data() {
return { auth }
},
methods: {
signInAnonymously
}
}
A button within my component's template then triggers the signInAnonymously method upon being clicked:
<button class="button" @click="signInAnonymously(auth)">Sign In</button>
This implementation seemed effective, but I couldn't shake the feeling that there might be a more streamlined or clearer way to structure the code. This led me to ponder two key questions:
- Am I approaching this correctly, or is there a more concise alternative?
- If I need to modify the
signInAnonymouslymethod per the Firebase documentation (i.e., adding.then(() => {}), how should I adjust the method within my export default so that it remains recognizable as the exported function from myfirebase.jsfile?
export default {
...,
methods: {
signInAnonymously(auth) {
...
}
}
