Fast abstract ↬

Quasar is an open-source Vue.js-based cross-platform framework that enables you, as a developer, to simply construct apps for each desktop and cell utilizing applied sciences resembling Cordova and Electron and writing your code as soon as. The app we’ll construct will retailer and get its knowledge from Firebase, that means that we’ll even be seeing the right way to use Firebase in Quasar.

On this article, I’ll clarify the right way to use Quasar Framework and its state-of-the-art UI (which follows Materials tips) to construct a notes app. The app will get its knowledge from and retailer its knowledge to Firebase. This tutorial is supposed for anybody all for constructing cross-platform functions that work nicely throughout all gadgets concurrently. On the finish of the article, you need to have a correct understanding of what Quasar is, the right way to get began creating apps with Quasar, and likewise the right way to use Firebase.

To comply with alongside on this article, you need to have:

  • an understanding of HTML, CSS, and JavaScript;
  • at the very least just a little expertise with Vue.js;
  • Node.js model 10 or above and npm model 5 or above put in in your machine.
  • data of how the command-line interface (CLI) works.

The deployed app is out there for viewing, and the ultimate code is on Github.

What Is Quasar Framework?

Quasar Framework is an open-source Vue.js-based cross-platform framework whose motto is: “write code as soon as and concurrently deploy it as an internet site, a cell app and/or an Electron app”. It has many options that allow you, as an internet developer, to construct apps on desktop and cell and to create progressive internet apps (PWAs) utilizing applied sciences resembling Cordova, Electron, and the net (Vue.js).

Why Quasar Framework?

Quasar is an easy-to-use however highly effective UI package comprising a number of UI elements, format parts, and helpers. Collectively, these parts present a full-featured toolset for constructing responsive front-end apps, with out your having to utilize many alternative UI libraries. It does the heavy lifting for you, permitting you to give attention to options and never boilerplate.

In abstract, Quasar presents assist for a lot of construct modes, together with:

  • single-page functions;
  • progressive internet functions;
  • server-side rendering;
  • cell apps (iOS and Android), utilizing Cordova or Сapacitor;
  • multi-platform desktop apps, utilizing Electron;
  • browser extensions.

Getting Began

To get began, let’s have a look at the right way to set up Quasar in your native machine and arrange a challenge.

Set up

There are 3 ways to start out utilizing Quasar:

  • embedding to an present challenge through a content material supply community (CDN);
  • putting in utilizing the Vue.js CLI Quasar plugin;
  • putting in utilizing the Quasar CLI.

For this tutorial, we will probably be utilizing the third methodology, which is the Quasar CLI. The very first thing to do is set up the Quasar CLI globally in your pc, or examine whether or not it’s put in by operating the next instructions in your CLI:

quasar -v #examine if quasar has been put in beforehand

yarn international add @quasar/cli
# or
npm set up -g @quasar/cli

As soon as that is achieved, now you can transfer on to organising the challenge.

Challenge Set-Up

Run the next command in your CLI:

quasar create <folder_name>

Following this, you’re going to be requested some questions. Right here is my full configuration for the app we will probably be constructing.

Now we are able to transfer into the challenge folder and begin up the appliance utilizing the next instructions:

cd <folder_name>
quasar dev

With the steps above full, our app needs to be operating on http://localhost:8080. That is what we should always see:

Quasar app

Quasar’s Folder Construction

The default software construction for Quasar is meant to be an ideal start line for builders to construct any sort of software. You’ll be able to set up the appliance nevertheless you want and create directories everytime you want them.

.

└── README.md                # readme to your app

The supply folder consists of about seven main directories {that a} newbie ought to care about:

  • quasar.conf.js
    That is the mind behind any Quasar software, as a result of most configurations are achieved on this file. Amazingly, Quasar handles many of the advanced configurations wanted by the varied instruments and packages that you just may use in an software. A few of these configurations are for:
  • src/property
    The property listing incorporates your uncompiled property, resembling Stylus or Sass information, pictures, and fonts.
  • src/elements
    That is the place your whole reusable elements will reside. These elements make up the completely different components of the appliance and may be reused and imported into your pages, layouts, and even different elements.
  • src/css
    You’ll not discover this in Vue.js, however Quasar offers this in order that we are able to have all of our international CSS in Sass kind. It consists of two information: app.sass is the place all of our types will go, whereas quasar.variables.sass incorporates the entire reusable variables we might need to make use of when styling our app. You may ignore the CSS listing should you really feel it’s of no use to you.
  • src/layouts
    This helps us create outlined layouts for an app with out repeating code. That is helpful whenever you need to embrace sidebars or mounted backside bars or have distinct layouts for cell and desktop.
  • src/pages
    The pages listing incorporates our software’s views and routes. Our pages are injected into the app and managed by way of Vue Router in /src/router/routes.js. Because of this every web page must be referenced there.
  • src/router
    This holds the routing configuration of our app. It consists of two folders:
    • /src/router/index.js holds the Vue Router initialization code.
    • /src/router/routes.js holds the routes of the app, loading our layouts alongside the routes or pages within the app.
      You may not must do something to the index.js file in a small challenge, but when your challenge can have routes, you’ll need so as to add them to the routes.js file.

Constructing a Notes App

When constructing an software with Quasar, the very first thing we’ll need to do is create a format. Quasar has made this course of so much simpler than some other framework by making use of a format builder. For our notes app, we’ll need one thing like the next, which is kind of just like the default format however with just a few modifications:

Building a notes app

(Massive preview)

App Format

Within the sidebar of Quasar’s documentation, you will notice the “Format and Grid” choice. Once you click on it, a dropdown will seem with extra choices, certainly one of which is “Format Builder”. Click on on “Format Builder”, which is able to convey you right here:

App layout

(Massive preview)

This enables us to decide on the choices we wish and take away those we don’t. Then, we might generate the code to stick within the format file.

App layout

(Massive preview)

The primary choice helps us to select the format components, whereas the second permits us to configure the format components. Lastly, we export the generated format.

If you need the very same format as mine, use the code beneath:

<template>
  <q-layout view="lHh lpR fFf">
    <q-header elevated class="bg-primary text-white">
      <q-toolbar>
        <q-btn dense flat spherical icon="menu" @click on="left = !left" />
        <q-toolbar-title>
          <q-avatar>
            <img src="https://cdn.quasar.dev/logo-v2/svg/logo-mono-white.svg" />
          </q-avatar>
          Title
        </q-toolbar-title>
      </q-toolbar>
    </q-header>
    <q-drawer show-if-above v-model="left" facet="left" bordered>
      <!-- drawer content material -->
    </q-drawer>
    <q-page-container>
      <router-view />
    </q-page-container>
  </q-layout>
</template>

<script>
export default {
  knowledge() {
    return {
      left: false
    };
  }
};
</script>

Take away the default format and paste the code above or the code that you’ve generated into src/layouts/MainLayout.vue.

The code above is split into three sections: the header (navbar), the drawer (sidebar), and the web page container (which incorporates the router view).

We’ve made use of the state-of-the-art UI to type the entire web page. As I stated earlier, when utilizing Quasar, you received’t want extra heavy libraries resembling Hammer.js, Second.js, or Bootstrap.

We will probably be including knowledge to the sidebar and modifying the navbar. When you’ve saved, you’ll discover our app now appears to be like like this:

Quasar app

(Massive preview)

Let’s work on the format, including some gadgets to the sidebar and altering the title of the app, Should you scan the format code that we added, you will notice the place we’re imagined to edit and add these numerous gadgets.

Here’s what my format appears to be like like after I’ve added gadgets to the sidebar and adjusted the title:

Quasar layout

(Massive preview)

And right here is the code:

<template>
  <q-layout view="lHh lpR fFf">
    <q-header elevated class="bg-primary text-white">
      <q-toolbar>
        <q-btn dense flat spherical icon="menu" @click on="left = !left" />
        <q-toolbar-title class="text-h6">
          My Notes
        </q-toolbar-title>
      </q-toolbar>
    </q-header>
    <q-drawer show-if-above v-model="left" facet="left" bordered>
      <q-list class="q-pt-xl">
        <q-item clickable v-ripple to="https://smashingmagazine.com/">
          <q-item-section avatar>
            <q-icon identify="house" measurement="md" />
          </q-item-section>
          <q-item-section class="text-weight-bold">House</q-item-section>
        </q-item>
        <q-item clickable v-ripple to="/about">
          <q-item-section avatar>
            <q-icon identify="data" measurement="md" />
          </q-item-section>
          <q-item-section class="text-weight-bold">About</q-item-section>
        </q-item>
      </q-list>
    </q-drawer>
    <q-page-container>
      <router-view />
    </q-page-container>
    <q-footer class="bg-grey-2 text-black ">
      <q-toolbar>
        <q-toolbar-title class="text-subtitle2">
          Designed and Constructed For this text.
        </q-toolbar-title>
      </q-toolbar>
    </q-footer>
  </q-layout>
</template>
<script>
export default {
  knowledge() {
    return {
      left: false
    };
  }
};
</script>

We eliminated the emblem within the navbar and edited the textual content, then added an inventory to the sidebar, making use of Quasar’s state-of-the-art UI. Take a look at the listing gadgets, and replica the code of any you want to use.

App Design

Earlier on, I stated I used to be going to make use of Quasar’s state-of-the-art UI (which follows Materials tips) to construct a notes app, and that’s what we will probably be doing now. Explaining the entire course of in an article like that is tough, however the “Model & Identification” part of Quasar’s documentation covers it nicely.

This will probably be a one-page app (index.vue), and right here is the code, with none styling utilized:

<template>
  <q-page class="">
    <div class="q-pa-md">
      <q-input
        bottom-slots
        v-model="newNoteContent"
        placeholder="Write your notice right here..."
        counter
        autogrow
        maxlength="300"
      >
        <template v-slot:after>
          <q-btn spherical dense flat icon="ship" />
        </template>
      </q-input>
    </div>
    <q-separator measurement="10px" />
    <q-list bordered class="rounded-borders" type="max-width: 600px">
      <q-item-label header>You've 3 Be aware(s)</q-item-label>
      <div>
        <q-item>
          <q-item-section high>
            <q-item-label caption class="text-grey-9">
              He who has creativeness with out studying has wings however no ft.
            </q-item-label>
          </q-item-section>
          <q-item-section high facet>
            <div class="text-grey-9 q-gutter-xs">
              <q-btn measurement="13px" flat dense spherical icon="delete" />
            </div>
          </q-item-section>
        </q-item>
        <q-separator measurement="1px" />
      </div>
      <div>
        <q-item>
          <q-item-section high>
            <q-item-label caption class="text-grey-9">
              He who has creativeness with out studying has wings however no ft.
            </q-item-label>
          </q-item-section>
          <q-item-section high facet>
            <div class="text-grey-9 q-gutter-xs">
              <q-btn measurement="13px" flat dense spherical icon="delete" />
            </div>
          </q-item-section>
        </q-item>
        <q-separator measurement="1px" />
      </div>
      <div>
        <q-item>
          <q-item-section high>
            <q-item-label caption class="text-grey-9">
              He who has creativeness with out studying has wings however no ft.
            </q-item-label>
          </q-item-section>
          <q-item-section high facet>
            <div class="text-grey-9 q-gutter-xs">
              <q-btn measurement="13px" flat dense spherical icon="delete" />
            </div>
          </q-item-section>
        </q-item>
        <q-separator measurement="1px" />
      </div>
    </q-list>
  </q-page>
</template>
<script>
import db from "src/boot/firebase";
export default {
  identify: "PageIndex",
  knowledge() {
    return {
      primary: false,
      mounted: false,
      newNoteContent: ""
    };
  }
};
</script>

Within the code above, we’ve got an enter subject from Quasar. We’ve hooked up a v-model to get the info from the enter subject as soon as the “Submit” button is clicked. We even have an inventory of things that will probably be used to show every notice, and every listing merchandise has an icon used to delete that exact merchandise when clicked.

Setting Up Native Information

At this level, the design of our app is in place. The following factor we’ll do is create an array that will include all of our notes. We’ll be certain that we are able to add to and delete from this array earlier than organising Firebase.

Right here is the array that we’ll be making use of in our app for now. Later, we’ll take away this array or remark out the code.

notes: [
  {
    id: 1,
    noteContent: "Lorem ipsum dolor sit amet consectetur adipisicing elit. Ea vereprehenderit aspernatur mollitia saepe cupiditate pariatur natus accusantium esse repudiandae nisi velit provident corporis commodi eius fugiat reiciendis non aliquam."
  },
  {
    id: 2,
    noteContent: "Lorem ipsum dolor sit amet consectetur adipisicing elit. Ea vereprehenderit aspernatur mollitia saepe cupiditate pariatur natus accusantium esse repudiandae nisi velit provident corporis commodi eius fugiat reiciendis non aliquam."
  },
  {
    id: 3,
    noteContent: "Lorem ipsum dolor sit amet consectetur adipisicing elit. Ea vereprehenderit aspernatur mollitia saepe cupiditate pariatur natus accusantium esse repudiandae nisi velit provident corporis commodi eius fugiat reiciendis non aliquam."
  }
]

Fetching Information

We now have our array. Let’s add these knowledge to our app. As a result of we perceive Vue.js, all we’ll do is loop by way of this array utilizing the v-for directive, use the info gotten from the array, after which put the content material wherever we wish it to look.

<div v-for="noteContent in notes" :key="noteContent.id">
  <q-item>
    <q-item-section high>
      <q-item-label caption class="text-grey-9">
        {{ noteContent.notice }}
      </q-item-label>
    </q-item-section>
    <q-item-section high facet>
      <div class="text-grey-9 q-gutter-xs">
        <q-btn
          measurement="13px"
          flat
          dense
          spherical
          icon="delete"
          @click on="deleteNote(noteContent)"
        />
      </div>
    </q-item-section>
  </q-item>
  <q-separator measurement="1px" />
</div>

We additionally added a click on occasion handler to the delete button, in order that it hundreds this operate at any time when it’s created.

Including Notes

Let’s see the right way to add notes to our app by utilizing the enter subject. We’ll use JavaScript’s unShift() strategies, which provides a number of parts to the start of an array and returns the brand new size of the array.

The very first thing to do is so as to add a click on occasion handler to the button.

<q-btn spherical dense flat icon="ship" @click on="addNote" />

Then, proceed to create this methodology within the script space.

strategies: {
  addNote() {
    let newNote = {
      id: this.notes.size + 1,
     notice: this.newNoteContent
    };
    this.notes.unshift(newNote);
    this.newNoteContent = "";
  }
}

Within the code above, we created an object for the brand new notice, which contains the ID and the notice itself, after which we added this newNote to the array of notes through the unShift() methodology.

Deleting Notes

Lastly, earlier than continuing to make use of Firebase in our app, let’s see the right way to delete a notice. The very first thing can be so as to add an occasion listener to the delete icon:

<q-btn
  measurement="13px"
  flat
  dense
  spherical
  icon="delete"
  @click on="deleteNote(noteContent)"
/>

After which we might create a way:

deleteNote(noteContent) {
  let noteId = noteContent.id;

  //doing this to get the true id of the notes
  let index = this.notes.findIndex(noteContent => noteContent.id === noteId);
  this.notes.splice(index, 1);
}

On this code, we obtained the id of the actual notice that we need to delete by way of the parameter handed to the press occasion methodology that was created. Then, we made use of the splice methodology to take away solely that merchandise from the array.

Firebase

Now that these two items of performance work, let’s now see how we are able to use Firebase in Quasar so as to add, fetch, and delete knowledge. Firebase can even give us real-time knowledge syncing throughout all gadgets. The information in our app received’t be very a lot, as a result of it’s only for the aim of studying. In case you’re pondering of one thing large that will be utilized by hundreds of thousands of individuals, try the pricing web page.

Firebase is software growth software program from Google that permits us to develop iOS, Android, and internet apps.

Setting Up Cloud Firestore

To get began, go to firebase.google.com and click on on both the “Go to console” hyperlink within the top-right nook of your display or the “Get began” button (be certain that you check in along with your Google account).

Firebase website

(Massive preview)

This may convey us to the console space, the place we are able to create a challenge. Click on on the “Add a challenge” button, and a kind to create your challenge will seem. The primary query will request the challenge’s identify, which may very well be something; for this text, we’ll name it “notesApp”. Let’s additionally disable Google Analytics as a result of ours is a mini-app.

Google Analytics for your Firebase project

(Massive preview)

Click on on the “Create challenge” button (this may take few seconds, so be affected person). Then, click on on “Proceed”, in order that we are able to create our cloud Firestore.

Within the sidebar, click on on “Firestore”, after which “Create database”.

Cloud Firestore

(Massive preview)

This may convey up a modal. Click on on “Begin in take a look at mode”, which is able to make it straightforward for us to start out working with our database. Keep in mind that, “The default safety guidelines for take a look at mode enable anybody along with your database reference to view, edit and delete all knowledge in your database for the subsequent 30 days”.

Create database

(Massive preview)

Click on on “Subsequent”, go away the default Cloud Firestore location, after which click on on the “Allow” button. As soon as it hundreds, our database will probably be absolutely prepared for us to make use of.

Be aware: The Firebase database is made up of collections, and these collections include paperwork, and every doc is a JavaScript object that has fields in it.

Let’s get began by creating a brand new assortment for our notes.

To create a set, click on on “Begin assortment”. A modal will pop up so that you can enter the gathering ID — that means, a reputation. Then, click on on the “Subsequent” button.

Click on “Start collection”

(Massive preview)

Now you can begin creating the paperwork and fields for every notice. Auto-generate the ID of the doc to make sure that it’s distinctive by clicking “Auto-ID” beside the doc subject.

Add a document

(Massive preview)

Click on “Save”, and proceed to create extra paperwork. Ultimately, that is what my database appears to be like like:

(Massive preview)

Now that we’re achieved, let’s see the right way to join Firebase to our app. Go to “Challenge overview” within the sidebar, and let’s add this to an internet app by clicking the “Internet” button.

Go to “Project overview” in the sidebar, and add this to a web app by clicking the “Web” button

(Massive preview)

A kind will seem for us to “Add Firebase” to our internet app. We’ll give it the identical identify, “notesApp”, and register the app (don’t examine the “Firebase internet hosting” subject).

As soon as it has loaded, it is going to convey up an SDK to assist us initialize our database within the app. We received’t do it this fashion, though we’ll want some data from the generated SDK. The suitable method to do that in Quasar is to import the modules that we want and use a boot file.

So, go away that tab open, and let’s see the right way to add the Firebase SDK and initialize Firebase in our Quasar app.

The very first thing to do can be to put in Firebase in our challenge with npm.

npm set up --save firebase

As soon as set up is full, we’re going to initialize our app’s connection to Firebase by making a boot file, in order that we’ve got rapid entry to the database when our app is prepared.

A boot file helps us to run code earlier than the app’s Vue.js root part is instantiated. Quasar’s documentation has extra details about boot information and when to make use of boot information.

To generate a boot file, we’ll run this command in our CLI:

quasar new boot firebase

Be aware: You don’t want to make use of Firebase because the identify of the boot file.

As soon as that is achieved, you’ll discover that the file is now created within the boot folder. To utilize this newly created boot file, we’ll want so as to add it to the quasar.config.js file’s boot array.

quasar.config.js file’s boot array

(Massive preview)

Let’s return to the newly created boot file. Delete the entire code there as a result of we don’t want it. We’ll import the modules that we want and configure our database. Paste within the following code:

import firebase from "firebase/app";
import "firebase/firestore";

const firebaseConfig = {
  // ...
};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);

Right here, we’ve imported Firebase itself and Firestore, and we’ve initialized Firebase, making use of the config, which we will probably be including now.

At this level, we’re virtually achieved configuring our app. We have to add our distinctive configuration, which was offered within the SDK that was generated after we added Firebase to our internet app. Copy solely the configuration, and paste it into our array.

Add Firebase SDK

(Massive preview)

We should always now have one thing like this:

import firebase from "firebase/app";
import "firebase/firestore";
const firebaseConfig = {
  apiKey: "AIzaSyDRcq5PXJSi5c5C8rl6Q6nudIJqTFaxXeA",
  authDomain: "notesapp-ffd7c.firebaseapp.com",
  projectId: "notesapp-ffd7c",
  storageBucket: "notesapp-ffd7c.appspot.com",
  messagingSenderId: "18944010047",
  appId: "1:18944010047:internet:ddfb46fc6bc8bba375158a"
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);

One very last thing, since we’re making use of Firestore, is that we’ll must initialize the cloud Firestore by including this code to our boot file (the final line):

let db = firebase.firestore();
export default db;

This db will give us entry to our Firestore database. We additionally exported it in order that we are able to use it anyplace in our app.

At this level, you may nonetheless be just a little confused, however when you’ve got adopted this information, then you’ll have correctly initialized Firebase to your software. You’ll be able to learn extra about including Firebase to your JavaScript challenge within the documentation.

Fetching Information From Firebase

When you’ve got adopted the information to date, every little thing ought to work effective when you launch your app. Now let’s seize the notes created within the database and show them in our app.

For this, we will probably be making use of the .onSnapshot hook, which will probably be fired any time the info in our assortment adjustments. This may inform us whether or not a doc has been added, eliminated, or up to date. For this information, we’ll solely cope with the addition and removing of paperwork. Utilizing hooks like this makes real-time syncing throughout gadgets doable. Let’s get began.

The very first thing to do can be for us to get entry to the database by importing it into the index web page of our app.

import db from 'src/boot/firebase';

Then, create a mounted hook, as a result of we need to fetch our knowledge instantly after the app has loaded.

mounted() {
  db.assortment("notes").onSnapshot(snapshot => {
    snapshot.docChanges().forEach(change => {

      let noteChange = change.doc.knowledge();

      if (change.sort === "added") {
        console.log("New notice: ", noteChange);
        this.notes.unshift(noteChange);
      }
      if (change.sort === "modified") {
        console.log("Modified notice: ", noteChange);
      }
      if (change.sort === "eliminated") {
        console.log("Eliminated notice: ", noteChange);
      }
    });
  });
}

Within the code above, we’re merely grabbing our notes assortment, and each time there’s a change within the assortment, the onSnapShot methodology will probably be fired, which is able to return a snapShot of all our knowledge. All of those knowledge will probably be objects with sort properties. These sort properties will inform us the kind of change that has occurred and provides us entry to the info that was both added, modified, or eliminated.

This may sound complicated, however you’ll perceive what we’re doing as you learn on.

Should you save your code and examine the console setting, you’ll discover that every notice has been logged out. We will now push these objects to the notes array that we created earlier, in order that we are able to show real-time knowledge in our software.

The very first thing to do is delete or remark out the objects within the notes array, in order that we’ve got one thing like this:

notes: []

Then, go the objects to this array:

this.notes.unshift(noteChange);

Your code ought to now appear to be this:

if (change.sort === "added") {
  this.notes.unshift(noteChange);
}

At this level, should you load the app, you’ll discover that you’ve efficiently fetched your knowledge from Firebase.

Including Information to Firebase

Let’s see the right way to add a notice to our notes assortment on this app. At this level, should you attempt to use the enter subject so as to add a notice, it is going to work however the notice will disappear when you refresh the web page as a result of it’s not saved in any database.

To do that with Firebase, all that’s wanted is to replace the addNote() methodology that we created earlier.

addNote() {
  let newNote = {
    // id: this.notes.size + 1,
    notice: this.newNoteContent
  };
  // this.notes.unshift(newNote);

  db.assortment("notes")
    .add(newNote)
    .then(docRef => {
      console.log("Doc written with ID: ", docRef.id);
    })
    .catch(error => {
      console.error("Error including doc: ", error);
    });

  this.newNoteContent = "";
},

The very first thing we did right here was take away the ID that’s used after we made use of the earlier array, as a result of we are actually going to auto-generate the ID from Firebase. We additionally eliminated the unshift() methodology; it’s not helpful as a result of knowledge is being fetched for our app as soon as there may be an replace utilizing the snapShot hook.

If we have a look at the code answerable for updating the Firestore db, all we’re passing to the gathering (notes) is the brand new object (newNote), and this operate will robotically generate an ID for every of our paperwork. The documentation has extra data on including knowledge to Firebase.

Deleting Information From Firebase

We’re virtually achieved with our app, however we want to have the ability to delete knowledge in our app from Firebase. Presently, the delete operate works, however should you reload the app, the deleted knowledge will reappear.

As we did earlier than, we’re going to delete these knowledge (or paperwork) from Firebase utilizing the distinctive ID generated by Firebase.

Presently, we don’t have entry to the ID. To entry it, we’ll add it to the noteChange object:

noteChange.id = change.doc.id;

As soon as that’s set, deleting knowledge will probably be as straightforward as including it. All we’ve got to do is go to the deleteNote(noteContent) methodology that we created beforehand, delete the earlier code, and make use of this:

deleteNote(noteContent) {
  let noteId = noteContent.id;
  db.assortment("notes")
    .doc(noteId)
    .delete()
    .then(() => {
      console.log("Doc efficiently deleted!");
    })
    .catch(error => {
      console.error("Error eradicating doc: ", error);
    });
}

This checks the notes assortment for a doc with the desired ID after which deletes it. But when we save our code now and click on the delete icon, the info will delete however received’t go away the app’s interface until we refresh our code, that means that the snapshot hook must be up to date. Go to the snapshot hook for eliminated, and add this code:

if (change.sort === "eliminated") {
  console.log("Eliminated notice: ", noteChange);
  let index = this.notes.findIndex(
    noteContent => noteContent.id === noteChange.id
  );
  this.notes.splice(index, 1);
}

This merely will get the ID of the put up that we deleted and removes it from the interface.

With that achieved, we’ve got constructed an app with Quasar that works with Firebase. One main benefit of Quasar is that it permits us to concurrently deploy our challenge as an internet site, cell app, or Electron app.

To deploy for iOS, Cordova must be put in on our native machine. A MacBook is very preferable. Navigate to your CLI, and set up Cordova globally:

$ npm set up - g cordova

To put in on Home windows, you’d make use of Electron. The documentation correctly explains how to do that.

Conclusion

On this information, we’ve got constructed a notes software utilizing Quasar and Firebase. By following this information, you are actually able to enhance on and add your personal options and performance. Listed below are just a few concepts to get you began:

  • Implement performance to change notes.
  • Add dates, so to order the info by date.
  • Model the app, and make it extra inventive.
  • Add pictures.
  • Much more.
