On-Demand VueJS Developers in Ahmedabad for Scalable Web Applications

In today's fast-evolving digital landscape, VueJS has emerged as one of the most popular JavaScript frameworks for building responsive, dynamic, and highly interactive user interfaces. Businesses in Ahmedabad, one of India's booming IT hubs, are increasingly recognizing the power of VueJS for both web and mobile app development. If you're considering hiring on-demand VueJS developers in Ahmedabad, this comprehensive guide will walk you through everything you need to know.

Why VueJS is the Go-To Framework for Modern Web Development

VueJS stands out for its simplicity, flexibility, and performance. Whether you're building a single-page application (SPA), an eCommerce platform, or a dynamic dashboard, VueJS is versatile enough to cater to a wide range of development needs. What makes VueJS truly remarkable is its ability to create smooth, responsive UIs that enhance the user experience.

For businesses in Ahmedabad, hiring on-demand VueJS developers means leveraging the best technology stack for your front-end development needs without the hassle of long-term commitments.

Hire On-Demand VueJS Developers in Ahmedabad

Hiring VueJS developers is not just about finding someone who knows the framework; it's about finding the right talent who can understand your business objectives and transform them into functional code. Here are the steps to hire the best VueJS developers in Ahmedabad:

1. Define Your Project Scope and Requirements

Before you start your search, make sure you clearly define the project scope. Are you building a single-page application, a dashboard, or perhaps an eCommerce store? Identify the features, functionalities, and user experience that you want to deliver. This clarity will help in finding a developer who fits your specific needs.

2. Choose Between Freelancers and Development Agencies

In Ahmedabad, you have two main options: hiring freelance VueJS developers or working with a development agency like i-Quall. Freelancers may offer flexibility and cost advantages, but agencies bring a wider talent pool, quality assurance, and project management expertise. Depending on the size and complexity of your project, you might find one option better suited to your needs.

3. Evaluate Developer Expertise

Look for VueJS developers in Ahmedabad with a solid portfolio of work. Check if they have experience in your specific industry or in developing applications similar to what you're planning. Look for expertise in front-end technologies like HTML, CSS, and JavaScript, along with experience working with Vue.js’s ecosystem, including Vuex for state management and Vue Router for routing.

4. Conduct Interviews and Technical Tests

Once you've shortlisted candidates or agencies, conduct interviews to gauge their understanding of your project and their development process. A technical test or live coding session can help you evaluate their problem-solving abilities and VueJS expertise.

5. Agree on the Budget and Timeline

Clearly outline the project milestones, deadlines, and payment structure before starting any development work. Whether you choose to work with freelancers or an agency, it’s important to have clear agreements to ensure a smooth development process.

Understanding VueJS Development

When hiring on-demand VueJS developers in Ahmedabad, it's helpful to have a foundational understanding of VueJS and how it works. Here's a quick breakdown:

1. Two-Way Data Binding

VueJS allows for two-way data binding, which means any changes in the UI are reflected in the model and vice versa. This feature simplifies the management of forms and input fields, making VueJS particularly useful for applications with dynamic data entry.

2. Component-Based Architecture

VueJS uses a component-based architecture, meaning you can break down your UI into smaller, reusable components. This modular approach makes your code more maintainable and scalable, which is essential for long-term projects.

3. Virtual DOM

The virtual DOM is a lightweight copy of the actual DOM, and VueJS updates only the parts of the DOM that have changed, which makes it extremely fast. This leads to better performance, especially for complex, high-traffic applications.

VueJS Application in Action

Consider an eCommerce platform built using VueJS. The application needs to handle thousands of products, manage user accounts, and update product availability in real time. Using VueJS developers in Ahmedabad, you can:

Build dynamic product filters that instantly update as the user applies criteria (price range, category, etc.).

Enable real-time cart updates without needing to refresh the page.

Implement an efficient checkout process with client-side validation using VueJS forms.

This modular, component-based approach ensures that each element of the UI works independently, making the app faster and more reliable.

When looking to hire VueJS developers in Ahmedabad, consider i-Quall, a reputed development agency known for its expertise in VueJS development. i-Quall offers a team of experienced developers who understand how to deliver quality code while keeping user experience at the forefront. Whether you're a startup looking for rapid development or an enterprise needing scalable web solutions, i-Quall has a proven track record of delivering high-quality projects on time and within budget.

i-Quall's developers are well-versed in the VueJS ecosystem, including Vuex and Vue Router, ensuring that your application not only meets but exceeds your expectations. By partnering with i-Quall, you can rest assured that you're working with the best VueJS developers in Ahmedabad.

VueJS & Firebase Cloud Firestore Stripped-Back - Tutorial Part 2

In this tutorial series we are using a stripped-back approach to getting started with Vuejs & Firebase Cloud Firestore to build full-stack web applications. No CLIs or build tools just a HTML page.

Putting the ‘C’ in CRUD

Welcome back to our Vue and Firebase stripped back tutorial. If you skipped part 1 of this tutorial you can get it here.

Let’s start straightaway from where we left off in part 1 and start looking at how we can develop our employee tracker app, EmployeeMagic, to let the user add records to their employee database. This represents the C in CRUD (Create, Read, Update, Delete).

We’ll start by adding some input boxes to our template for the user to be able to add employees. The fields we want are first and last names, job title, department and age.

Let’s start by adding a First Name field.

<body>

<h1>{{ appTitle }}</h1>

<label>First Name</label> <input type=“text” v-model=“firstName”>

</div>

</body>

Notice the input element, we’ve added a Vue directive to it called v-model and we’ve assigned it a value of firstName. For AngularJS devs this will seem very familiar. v-model is a data binding directive that binds the input element to a variable in our view model (the data in the Vue Instance Object). Therefore whatever value the user keys into the input box will be automatically assigned to a variable in your Vue Instance Object. Now we don’t presently have a firstName variable in data in our Instance Object so we need to add it and assign it an initial value, in this case an empty string.

Just to prove that our data-binding in Vue is working and is in fact working in both directions (from the template to the Instance Object and from the Instance Object to the template), also called two-way data binding, we’ll stick a double-curly on the end of the input box eg

<input type=“text” v-model=“firstName”>{{ firstName }}

Save the file and refresh the page in your browser. As you begin to type in the First Name box, the name is displayed at the side of it. The input is assigning it to the firstName variable (via the v-model directive) and Vue is watching for changes in the firstName variable and when it detects one it changes anywhere in the page where firstName has a binding, in this case via the double-curly.

OK, enough of the fun and games, let’s add our other fields to the template and create their corresponding variables in the data section. As we’re grouping several fields together to form an employee we’ll change it to put them all in their own object called employee and change the template to bind the input boxes to the relevant properties on the employee object instead. We’ve proved our point with the two-way data binding for now so we’ll remove our double curly.

<body>

<h1>{{ appTitle }}</h1>

<label>First Name</label> <input type=“text” v-model=“employee.firstName”></br>

<label>Job Title</label> <input type=“text” v-model=“employee.jobTitle”></br>

</div>

</body>

Notice that on the Age input we’ve added an extra command to the v-model directive, :number. This is very useful in Vue as, although the type of the input is set to number so the user cannot input anything other than valid numbers, by default when the value is converted by the binding to Vue data properties, it is converted as a string. As we want the age property to remain a number type, the v-model:number directive is required. <script> var app = new Vue({ el : '#app’, data : { appTitle : ‘EmployeeMagic’, mainStyle : { ‘margin’ : ’20px’ }, employee : {firstName : ‘’, lastName : ‘’, jobTitle : ‘’, dept : ‘’, age : 0 } } }) </script> We’ll next add a Save button which will write the entered employee to the database. To carry out the task of saving when the user clicks the Save button we need to hook the button into our Vue Instance Object and call a function that’s run to save our new employee record. To do this we need to use another Vue directive called v-on:click

</div>

</body>

v-on is used to handle events and the :click is the specific event to be triggered on. We then assign the function that we want to run once the event (click) is triggered, in this case saveEmployee().

If you remember, in part 1 of this tutorial we mentioned that when using the v-bind directive along with a colon-command that you could use shorthand instead by dropping the v-bind eg v-bind:style could be entered as just :style for short. The same applies to the v-on directive however as it’s an event, rather than using the colon, you must use a @ instead. Therefore instead of using v-on:click you could use the shorthand version which is @click. Ultimately it’s a matter of preference and usually I would use the shorthand but to provide full explanations in these tutorials we’ll stick to using the verbose style.

We now need to write our saveEmployee() click handler function. This involves declaring functions or methods in our Vue Instance Object which you can do by declaring a new first-level object on the Instance Object called methods. All of your logic for our app will live in functions declared in Vue’s methods object. <script> var app = new Vue({ el : '#app’, data : { appTitle : ‘EmployeeMagic’, mainStyle : { ‘margin’ : ’20px’ }, employee : {firstName : ‘’, lastName : ‘’, jobTitle : ‘’, dept : ‘’, age : 0 } }, methods : { saveEmployee : function() { alert(‘You have saved ‘ + this.employee.firstName + ‘ ‘ + this.employee.lastName) } } }) </script> So, you can see that we’ve declared a saveEmployee function within the top-level methods object. In the above we’re not saving anything, we’re just going to display a standard alert message which includes displaying the last name and first name of the employee we’re saving. Notice that we’re using this to refer to our employee properties. Any variable declared in the data object of our Instance Object that we want to reference in our methods must be referenced using this, otherwise Vue won’t recognise it. As anyone who has worked with Javascript for any length of time knows, using this can be problematic as what it points to can change depending on the context from where it was called. There are ways around using this which we’ll discuss later but we’ll just stick with it as it is for now. Save the file, refresh your browser and enter the details of an employee, click Save and you should see the alert message appear. We’re now at the point of needing to be able to physically save our new employee to our Firebase Cloud Firestore. To get started with this you just need a bog-standard Google account. If you’ve got a gmail account or use any of Google’s products where you need to log-in then you’ve got a Google account. If not then you’ll need to create one which you can do on the Firebase site. To get started go to the Firebase web-site (https://firebase.com) and click Go To Console. If you’re not signed in to your Google account or you don’t have one you’ll then be taken to the usual sign-in/sign-up pages to get going, otherwise you’ll be taken to the Firebase console. Click Add Project and enter a project name and select your region. Once in the main console click the Database option on the left. You’ll be given the option of Realtime Database or Cloud Firestore. Make sure you select Cloud Firestore. You’ll also be asked how you want the security level to be setup, make sure you select Development/Test mode otherwise you’ll have to start setting up security rules manually which are a whole other subject altogether. Your Cloud Firestore will then be setup, which might take a short while. Once your database is setup we don’t need to do anything else in the database console however we do need to grab the code and libraries for getting Firebase into our app. To do this click the Project Overview option on the left. In the Get Started page click on the option for Add Firebase to your web app. In the window that pops up you’ll see a code snippet, just click the Copy button. Go back to your editor and paste the code snippet below the closing </body> tag and above the VueJS CDN script tag as shown below : </body>

A brief explain of Promises

If you’re not familiar with promises, they’re simply a way to handle asynchronous code. Asynchronous functions are just standard functions which carry out some processing but return control back to the caller before completing it’s process (to avoid blocking the app’s execution). Async functions usually return a promise object which enables the code which called the function to implement any tasks that needs to execute only after the async function has fully completed it’s process. In this instance we only want to clear the input boxes once we know that the employee has definitely saved. To do this we call then() which is a function on the returned promise object. then() accepts a function as a parameter which we use to execute any code we want after we know the save has completed, in this case to clear the employee properties and inputs. As we’ve done above you can also chain a call to the promise’s catch() function to execute any code should the async function not succeed. With all of that said, the new changes we’ve just made WILL NOT WORK!! And they will not work because of the this issue that was foretold. The reference to this changes depending on the context in which it was called. Therefore when we come to execute the code that is passed to the then() or catch() functions, this points to something else other than our Instance Object data and we’ll get errors! There are a couple of ways around this. The traditional way is to simply assign this at the beginning of a function to another variable, usually called that, and then reference that instead of this throughout the function to be sure that you’ll always reference the desired object. This works but it means you’re always having to remember to implement it at the beginning of every method. The other way is to reference the Instance Object explicitly where you know this won’t work for you. In this tutorial we declared a variable to contain our Vue Instance Object called app eg var app = new Vue({. You can therefore call app.clearEmployee() instead of this.clearEmployee() in the then() function and it would work. The problem is that context again gets in the way and you cannot use an explicit reference to the Instance Object in it’s own context so saying app.db.collection(‘Employees’).add(app.employee) in the main saveEmployee() function won’t work either, so you’d end up using this in some places and app in others.    The ideal solution would enable us to use one way throughout to refer to the properties and methods on your Instance Object to ensure consistency but without additional workload that you would need to remember to implement on each method. Fortunately ES6/ES2015 introduced arrow functions which help us resolve this problem. With arrow functions we can use an explicit reference to the Instance Object in every context throughout our methods. Arrow functions, from a declarative standpoint, simply change a function declaration from : function() { }

to () => { } So let’s change our saveEmployee() function from a standard function declaration to an arrow function and do the same with the then() and catch() functions. Then replace every reference of this to app. saveEmployee : () => { if ((app.employee.firstName) && (app.employee.lastName)) app.db.collection(‘Employees’).add(app.employee) .then(() => { app.clearEmployee() }) .catch(() => { console.log(‘Error saving employee ‘ + app.employee.firstName + ‘ ‘ + app.employee.lastName) }) else alert(‘You must enter both a first and last name to save.’) }, For consistency purposes we should also change our clearEmployee() method as well clearEmployee : () => { app.employee = { firstName : ‘’, lastName : ‘’, jobTitle : ‘’, dept : ‘’, age : 0 } } The only exception to this rule is the created lifestyle hook function where the VueJS docs expressly recommends not declaring it as an arrow function so we’ll leave it as a standard function declaration (including referencing this rather than app). Like with Promises, arrow functions are a fairly new addition to JS so you must be using an evergreen browser, like Chrome, which implements them natively otherwise you’ll need to use a transpiler such as Babel. We’ve now completed the Create task from our CRUD list. In this tutorial we’ve added input boxes and bound them to properties on our view model to create 2-way data binding. We’ve added events and methods to our Instance Object, created a Firebase Cloud Firestore project and hooked it into our app, covered Vue’s lifecycle hooks to initialise a reference to our database and then covered how to save employees to our Cloud Firestore. Finally we covered the issues with using this and how arrow functions can help us overcome these problems. In the next part of the tutorial we’ll cover the R in CRUD, Reading (or Retrieving) employees from our database. We’ll cover getting data back from our Firestore and explain how to implement realtime updates. I hope you’ll join me.
