Vue PocketBase: Guide to Authentication and User Management

Vue PocketBase #1 Authentication And User Management

In this tutorial, we will be exploring how to set up authentication and user management in a Vue.js application using Vue PocketBase. Vue PocketBase is a lightweight and flexible library that helps you manage and authenticate users in your Vue.js applications.

Step 1: Installation

To get started, we first need to install Vue PocketBase in our Vue.js project. We can do this by running the following command in the terminal:

npm install vue-pocketbase

Step 2: Set up the Pocketbase instance

Next, we need to create a Pocketbase instance and configure it with our Firebase credentials. Firebase is a popular backend service that provides authentication and database functionalities. To set up the Pocketbase instance, we can create a new file called "pocketbase.js" in our project and add the following code:

import Pocketbase from 'vue-pocketbase';
import firebase from 'firebase';

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  databaseURL: "YOUR_DATABASE_URL",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

const pocketbase = new Pocketbase({
  firebase: firebase
});

export default pocketbase;

Make sure to replace the placeholder values (YOUR_API_KEY, YOUR_AUTH_DOMAIN, etc.) with your own Firebase credentials.

Step 3: Set up authentication

Now that we have set up the Pocketbase instance, we can start implementing authentication in our Vue.js application. To do this, we can create a new component called "Auth.vue" and add the following code:

<template>
  <div>
    <h1>Authentication</h1>
    <button @click="login">Log in</button>
    <button @click="logout">Log out</button>
  </div>
</template>

<script>
import pocketbase from './pocketbase';

export default {
  methods: {
    async login() {
      try {
        await pocketbase.signInWithPopup();
      } catch (error) {
        console.error(error);
      }
    },
    async logout() {
      try {
        await pocketbase.signOut();
      } catch (error) {
        console.error(error);
      }
    }
  }
}
</script>

In this component, we have created a simple user interface with two buttons – one for logging in and one for logging out. We have also added methods to handle the login and logout functionalities using the Pocketbase instance.

Step 4: User management

Once authentication is set up, we can now add user management functionalities to our application. We can create a new component called "User.vue" and add the following code:

<template>
  <div>
    <h1>User Management</h1>
    <p>Welcome, {{ user ? user.displayName : 'Guest' }}</p>
  </div>
</template>

<script>
import pocketbase from './pocketbase';

export default {
  data() {
    return {
      user: null
    };
  },
  created() {
    pocketbase.onAuthStateChanged(user => {
      this.user = user;
    });
  }
}
</script>

In this component, we have displayed the user’s display name if they are logged in, or a default "Guest" message if they are not. We have also used the "onAuthStateChanged" method provided by Pocketbase to fetch the user data when the authentication state changes.

Step 5: Setting up routing

To navigate between the authentication and user management components, we need to set up routing in our Vue.js application. We can do this by creating a new file called "router.js" and adding the following code:

import Vue from 'vue';
import Router from 'vue-router';
import Auth from './Auth.vue';
import User from './User.vue';

Vue.use(Router);

export default new Router({
  routes: [
    { path: '/auth', component: Auth },
    { path: '/user', component: User }
  ]
});

Next, we need to update the main Vue instance in our "main.js" file to include the router:

import Vue from 'vue';
import App from './App.vue';
import router from './router';

new Vue({
  el: '#app',
  router,
  render: h => h(App)
});

Now, we can navigate between the authentication and user management components using the following routes:

• /auth: displays the authentication component for logging in and out
• /user: displays the user management component showing the user’s display name

That’s it! We have successfully set up authentication and user management in our Vue.js application using Vue PocketBase. Feel free to customize and enhance the functionality based on your specific requirements. Happy coding!
