Top 7 Interview Questions to Ask when Hiring Front-end Developers

Question 1: What would be the biggest motivation to use the latest standards of HTML5 and CSS3?

This can be a basic question to judge how updated the front-end developer is with the new versions of HTML and CSS. The expected answer would be that the new versions allow developers to add interactive graphics and media content including video and audio without the need of any additional plugins, such as Flash. In response to that, the new versions allow them to build SEO-semantic websites and deliver great cross-platform support.

Question 2: What are the basic steps to optimize the ‘perceived performance’ of a website?

Every front-end developer needs to know the best practices he can follow to optimize the perceived performance of the application. Henceforth, some of the right points would be around:

  • Cleaning up the HTML document
  • Reducing external HTTP requests
  • Sprites, image optimization and compressing images
  • Applying lazy loading functionality
  • Applying preload functionality to specific components
  • Incorporating JS scripts at the bottom of the page.
  • Minifying CSS, JavaScript, HTML.
  • CDN and Caching
  • Remove unused CSS

Question 3: What according to you is the best way for rapid prototyping and development of a web application?

This question allows you as an employer to understand what are the top front-end frameworks and front-end tools the developer prefers over others. In addition, it gives developers the opportunity to explain his favorite UI frameworks, CSS-preprocessors, and does he uses module bundlers. You can further ask him the reasons for his choices.

Question 4: What is the importance or need of a CSS preprocessor?

Most developers know how to use preprocessors and the answer you can expect would be along these lines:

Front-end development has become more interactive and cross-browser compatibility is a prerequisite for every application. In other words, CSS itself has limited capabilities to create cross-browser compatible style sheets and hence CSS preprocessors like SCSS/Sass or LESS offer an optimized way to write style sheets that can be compiled into CSS. They allow web developers to:

  • Define variables
  • Use nested index
  • Build and use mixins (functions)
  • Apply mathematical and operational functions

Question 5: What is the difference between Get and Post?

It is a basic question and the answer you can expect is-

A GET request is used for AJAX calls to an API, while a POST request allows the developer to submit data to the database repository or submit any data via a form.

POST request is more secure as it is used in two steps and it is not visible to the user, while the GET request is a single-step request that can be seen by the user in the URL.

Question 6: What is your approach to handling code testing?

This can be a good hint to find if the developer practices unit tests methods TDD (Test-Driven Development) or is conversant. As a result, you can ask to know the debugging and testing tools the developer uses.

hire frontend developer testing and debugging

Question 7: Have you ever encountered a cross-browser compatibility issue? Which has been your hardest experience with the same?

Top 10 Ways to Fine-tune AngularJS Framework Performance

Top 10 Ways to Fine-tune AngularJS Framework Performance

Leave a reply

AngularJS framework gives front-end developers all that they need for dynamic and impressive results. That’s why this open-source JavaScript framework, developed and maintained by Google, is so popular nowadays.

The modular approach and the huge support community make Angular even more hard-working and functional. Examine some of the world’s most popular websites, from Google to Amazon, and you’ll find Angular behind them.

The Many Benefits of AngularJS framework

According to a recent survey, 30.7 percent of software engineers now use Angular JS for user interfaces. The Angular developer community grew by a staggering 50 percent last year.

The Many Benefits of AngularJS framework performance

Source

Among the reasons that Angular is a preferred framework are:

  • It lets you bind data to HTML using expressions, with easy directives that extend functionality for new constructs. This creates simple and efficient software elements.
  • Because of its versatility, it can be used to create almost any type of web application.
  • The Angular bundle also allows you to manage both the front-end and back-end of projects using JavaScript, which is a big advantage.
  • Angular’s modular nature also allows for the separation of work between various teams. Thus, there is flexibility in the mode of operation as well as results.

How to Make AngularJS framework Even Better

Despite its many advantages, those who work with Angular have often felt the need for tweaks and optimizations in order to get first-class results.

When it comes to larger projects, such methods often make a big difference. The performance can be expected to be zero-issue following these adjustments.

Front-end Developers have come up with various ways to fine-tune Angular, depending on the nature of their projects. Here are ten of the most popular and effective techniques.

1. Use OnPush

Whenever something changes in your project, Angular runs change detection on all components. This could be incoming data or clicks, for example. This means that as the project grows, Angular needs to keep track of all the changes. However, you can adjust the Change Detection strategy to allow it to check only for specified events. This will make it run smoother and faster.

2. Use TrackBy

A component of the AngularJS framework works by identifying object uniqueness according to reference. This means that if you update the contents of the object, the related DOM node has to be recreated again. This happens even if the change is small and affects only a small section. To overcome this, you can use TrackBy, which ensures a better performance by tracking only the items that have been changed.

3. Avoid computing values in the template

Proficient front-end developers know that there are times when a server value has to be displayed in the consumer interface. Since Angular re-runs a function for every change detection cycle, this can become sub-optimal when it comes to resources. A solution is to use pure pipes because Angular executes a pure pipe only when it detects a pure change to the input value.

4. Disable change detection

This step is also linked to the above issue of constantly-evolving data. If you’re working on a component that depends on many such changes, it can become computation heavy. One efficient way to maximize performance is to detach the component’s change detector and configure it to check only at specified intervals.

5. Use lazy loading

In this case, instead of loading the complete app or program, only those modules can be loaded that are required at the time. This so-called lazy loading reduces time and increases efficiency by eliminating the loading of unnecessary components. This strategy is also known as asynchronous loading and can deliver a significant boost to performance.

Hire Dedicated Front-end Developers

6. Use Webpack

Those who use the latest version of Webpack for Angular CLI will find a significantly smaller and more manageable build size. For example, Webpack 4 has a mode option to specify the optimization type without the need for a specific configuration. This delivers great results for the environment. The build-time for Webpack 4 is also considerably less than that of earlier versions, which reduces development time for front-end developers.

7. Server-side rendering

By using Node.js, .Net, or PHP to render the first page of the application on the server as a static page, there is virtually instant rendering. This gives a boost to performance, speed, and overall user experience. For this type of server-side rendering, front-end developers use Angular Universal.

8. Avoid unnecessary third-party packages

It makes sense to check third party packages that are being used every once in a while to see if better options are available to reduce build size. In addition, JavaScript or AngularJS can natively execute small functionalities that eliminate the need for third-party additions. This, too, reduces size and, as such, is a worthwhile step to take.

9. Employ preload and prefetch attributes

With preload and prefetch attributes, front-end developers can load static resources quickly. This not only improves load times but also enhances the user experience. Although both attributes serve the same purpose, preload can be used with the assets necessary to render an initial frame. Prefetching is useful for resources that are required after the site has loaded.

 10. Use pipes instead of methods

The outputs of each relevant input parameter can be cached using pure pipes.

As a result, it will not be necessary to calculate values every time. We will only detect values that change. Naturally, this leads to a huge reduction in duplicate operations, which results in a significant improvement in performance.

What Else to Look when you Hire ReactJS Developers

While you need to check whether the developer has the requisite technical skills or not, there are other capabilities you should seek to ensure that your project will progress seamlessly and well, too.

Among these are:

  • The ability to communicate openly and honestly about the progress of a project, as well as the capacity to take feedback and work according to it.
  • The capacity to work as part of a team. The best developers are those who understand the entire project, their role in it, and the role everyone else plays.
  • A problem-solving mindset goes a long way in separating a basic developer from one who is perfect for your needs. Such developers will not only solve issues but will also be able to anticipate them even before they arise.
  • If your project is a specialized one or belongs to a specialized sector, it would be wise to see if the developer already has experience in that field. This will  go a long way in inspiring confidence.

The Advantages of Offshoring

With the popularity of ReactJS, as well as the high demand for developers, many companies have opted for a result-oriented solution. They offshore the work to skilled and specialized agencies.

The benefits of this are many.

  • Cost-effectiveness – When you outsource, investments in individual developer salaries in terms of keeping up with the latest technology and in providing office facilities are minimized.
  • Global skill sets – You get access to experience and expertise that is not limited to geography. Other aspects, such as adhering to deadlines as well as maintaining security, are also taken care of.
  • Greater focus – While the agency is efficiently taking care of your development goals, you can go ahead and focus on your core activities and meet business goals.
  • Timely delivery – With specialized agencies dedicated to your tasks, you can expect speedy execution and strict adherence to deadlines.
  • Scalability – Should you need to scale up your project, the offshore agency will always be able to add more resources to keep up with requirements. Otherwise, you may find that you have to suddenly invest more to match requirements.

According to a global outsourcing survey, cost-effectiveness is the primary reason for outsourcing.

The Advantages of Offshoring

Other reasons are to enable focus on core business and deal with capacity issues.

Service quality and access to intellectual capital also were important considerations.

  • It’s no wonder then that the global market for outsourcing is worth $85.6 billion and counting.
  • Of the businesses that use outsourcing, 65% say they would increase their outsourcing efforts in the future.
  • 78% of respondents say they feel positive about their outsourcing relationship with other companies.

India has been an industry leader in outsourcing, boasting a large number of skilled English-speaking workers at an affordable cost. According to 2017 outsourcing statistics, India is at the top, with an index of 7.07.

10 FAQs To Consider When Outsourcing Front-end Development

If there’s one thing that has changed the world of work, it’s the practice of outsourcing. Outsourcing has led to greater efficiency and cost savings, as well as flexibility, quality, and speed.

In our time, almost every industry has benefited from outsourcing. According to a recent study:

Global Outsourcing front-end development

Source

  • More than 30% of IT services have been outsourced.
  • The healthcare and finance sectors have seen an outsourcing growth of 36% and 30%, respectively.
  • For the HR sector, the figure stands at 32%.
  • Even in manufacturing, 43% is outsourced.

Nowadays, outsourcing is seen as an essential way for companies to bring about innovation, focus on core competencies, drive change, and keep up with the latest technological practices. 

Are you among those thinking of front-end outsourcing? Here are ten FAQs you should be aware of.

1. What are the Issues with Having the Team in a Different Location?

With a remote team working on your projects, you have access to top-line developers from all over the world. No longer do you have to be content with the developers locally available. You can check the portfolios, abilities, and experience of a wide variety of developers online to decide which one is a perfect fit. Yes, there will be different time zones, and this could mean a concern with instant, real-time responses. These can be overcome with initial planning as well as proper and managed deadlines.

2. Will Outsourced Front-end Developers Have the Skills I’m Looking For?

When you outsource, you have the choice of the most knowledgeable and up-to-date specialists. Their skills are always modernized and available for your benefit. This access to an international talent pool means constant insights, ideas, and innovations. Your digital presence can thus always appear fresh and appealing to your customers. 

3. Wouldn’t it be Less Expensive to Hire In-house Developers?

Hiring in-house developers leads to monthly operating costs – from salaries to office space, not to mention investment in technology and software. When you outsource, on the other hand, costs can be rationalized. A one-time operation means a one-time fee, and you can also negotiate contracts for the long-term to provide optimum savings. So the costs all depend on the scale of the work you have in mind.

4. Will An Outsourced Agency Give My Project Dedicated Attention?

Many businesses have opted for the model of a dedicated remote team in front-end outsourcing. This is when the client and agency agree beforehand on the project specifics and time needed. The agency then earmarks all the resources necessary for successful completion. This dedicated team works full-time on the project. In a manner of speaking, it becomes an in-house development team for the business. It provides the advantages of a crack development division, without the drawbacks.

5. Will there be Complications in Handling An Outsourced Team?

Front-end development is a specialized process, with tools and techniques being constantly updated. With in-house developers, care has to be taken to manage these improvements, with access to training as well as management control. In such cases, outsourcing is a much simpler means of operation. The end result needs to be made clear, and the agency’s development team will take care of the quality without the fuss.

6. What Happens if there is a Growing Amount of Work, and I Have to Keep Adding Resources?

As you must be aware, a company’s digital presence cannot remain constant and unchanged. New techniques and ways of interaction constantly spring up, and these should be incorporated for the best results. With an outsourced team, the initial phase of operations can be easily taken forward to encompass more methods of digital outreach. New skills and manpower can be added, depending on the need. On the other hand, such scalability of operations with an in-house team could mean constant hiring and managing. 

7. How Can I be Sure of a Consistent Level of Attention and Output?

Regular and trusted collaboration with a reliable offshore development team creates a level of consistency in business functions. Progress is regular, techniques and technology are streamlined, and there is uniformity of approach. Further, because the outsourced team is entirely dedicated to the progress of the project, handling deadlines becomes easier, leading to consistent turnaround times. Consistency is also possible with an in-house team, but this could mean giving up other benefits of outsourcing.

8. I Have Many Specialized Needs When it Comes to Front-end Work. Will Outsourcing be Able to Handle This?

An outsourced front-end developers team will comprise of many coding and software experts. Each one of these will be skilled in handling a specific task, with best practices being followed. The team project manager is the person who will bring this all together seamlessly, meaning you get results that are up-to-date as well as robust. 

9. Will An Outsourcing Agency be Equipped to Handle Different Customer Needs and Interfaces?

Today’s customers access the net in a variety of ways. For starters, they use different browsers. Then, there are different screens – from mobile phones to laptops to tablets. Businesses cannot ignore these diverse means of access, as it would mean potentially ignoring a large base. Offshore remote team developers are well-versed in the coding required for your digital presence to seamlessly switch between these modes. In-house developers, on the other hand, could well have the skillsets for only a few. 

10. What About Integration with the Back-end Team? 

Many times, companies find there is a lack of continuous collaboration between front and back-end developers. This can lead to issues of overall responsibility. An expert and experienced offshore development agency can resolve this during the preliminary discussion stage itself. Their team can ensure co-operation between front and back ends with a knowledge of security, server codes, security, and data management. In this way, operations can be coupled together, leading to integrated and hassle-free output.

At Uplers, we’re well aware of all of the above and more. We’re an offshore remote team provider company working with over 7000+ clients worldwide and can help you leverage the true potential of outsourcing for your front-end development requirements. Contact us today!

Outsource Front-end Development: 3 Moments that Sum Up My Experience

Outsource Front-end Development: 3 Moments that Sum Up My Experience

As someone responsible for making sure my company’s digital presence is attractive and engaging, a key part of my job is getting hold of experienced and responsible front-end developers. After all, I was keen for consumers to learn about what we could do for them, gain leads, and increase conversions. 

I knew we had all the data for this, but a great UI is a critical part of the process. It helps people stay interested, and brings out brand values and distinctiveness. A website is like an online shop window. The display has to be the best it can be.

The problem was, I wasn’t sure whether the locally available professional front end developers were a good fit. Some had knowledge of one aspect; others knew about some other technology. 

Some were too expensive, and others were too inexperienced. I kept wondering whether there was someone out there who could do it better.

What also bothered me was what would happen in the case of a breakdown or a critical issue. How time-consuming or expensive would it be to fix it in-house? Maybe a specialized agency with expertise and manpower was what was needed.

After keeping all the pros and cons in mind, I decided to outsource front-end development. Here were some of the things I kept in mind before I chose:

  • Experience – I checked if the agency had developed similar projects and had experience in the industry.
  • Portfolio – I examined the similar work they had done to see if it was up to standards.
  • Tech stack – It was also important to examine the capabilities and tech-stack of the potential vendors.
  • Digital presence – Very often, the vendor’s website and blogs give a good idea of their expertise and capabilities. I made sure to check this.
  • Communication and responsibility – I wanted to know whether there would be a dedicated point of contact in the agency, such as a project manager. And also the system they had in place for communication and feedback.
  • Testimonials – Which companies has the agency worked with before? Are they happy with the results? I spent a little time checking out their websites.

After these steps, I went ahead and chose. Fortunately, it turned out for the best.

Here are my top three learnings, if you’re in the same boat and wondering whether outsourcing makes sense.

Lesson 1: Time and Simplicity

Looking back now, I can see that what came as a relief was how much time I saved. Earlier, when I was going through resumes and co-ordinating interviews, many other IT duties were getting neglected. 

During the interviews, checking out the front-end developers’ hard and soft skills took time. After that came the shortlisting, final selection, salary negotiations, and so much more. 

Another factor was that the world of software coding is growing rapidly. I had to make sure I had knowledge of all the advances and techniques. Without that, I wasn’t able to properly judge which developer had the skills the company needed. 

When I outsourced front end development services, however, it came as a pleasant change. Once I located the right remote team, I had to only explain my needs and requirements. They took care of getting the right specialists and ensuring the right skills. Naturally, there were cost implications, but proper negotiations and planning took care of that aspect.

I must admit that there were a few initial hiccups because they were in a different time zone. Sometimes, there were natural delays in replying to e-mails or coordinating conference calls. 

I must say though that the team was totally dedicated to finishing the project according to the deadline. Fortunately, we didn’t have any time lag in waiting for the website to be ready. 

My expectations were met, without worrying too much about getting the right talent or managing and training them. Or even providing them with company space and access to technology.

Lesson 2: Speed and Flexibility

I’ve already mentioned that with an outsourced team, I didn’t have to worry about meeting deadlines. But another aspect of time-saving was the speed of response. 

At the start, I had to decide on the goals of the project and be very clear about requirements. This meant sharing all relevant information and helping with queries and clarifications. This homework was necessary.

Before everything fell into place, I also had to make sure that our back-end guys were completely aligned. I mean, there’s no point outsourcing the front-end if the rest is not in place. 

In the beginning, that did take some time. But once that was done, I could sit back and see the project taking shape before my eyes. And after that, if I had questions about the development process or any revisions, it was handled without fuss.

I was very clear about requirements from the start, so the team had adequate resources to keep the company’s digital presence in an optimal condition. This flexibility was important to us. Many times, they also came up with innovative solutions to meet our needs. 

Lesson 3: Quality and Robustness

With my outsourced front-end development team, I had access to qualified specialists with knowledge across technologies. There were so many aspects they took care of. For example, consumers with slower browsing speeds or accessing the net across devices and browsers.

Which means I got quality software with state-of-the-art, robust solutions. Problems were taken care of even before they arose.

Scalability was another aspect of this robustness. We started with a website, but I was told of so many other means of digital outreach. For example, a responsive web application with specific UI/UX design, a chatbot, blogs, and lots more.

If I had an in-house team, I’m not sure whether we would have been able to reach across platforms with ease. Who knows, we may even have had to write major portions of the software from scratch.

That didn’t happen, because the project manager of the team was always prepared to take care of issues. The team’s front-end specialists, designers and writers took care of the rest.

It made sense for me to outsource remote teams in terms of cost, because I knew from the start that there was going to be a continuous stream of work. If that hadn’t been the case, I would have had to pay people just to be on standby. 

To Conclude:

To sum it all up, be it capacity and quality, access to the latest skills, cost control or meeting deadlines, the decision to outsource front-end development was one I never regretted. 

Why-Front-end-Developers-are-Hard-to-Find-with-Expertise-in-React.js-Node.js-or-AngularJS

ReactJS Front-end Developers are Hard to Find. What is the Solution?

ReactJS is nowadays one of the most popular JavaScript libraries to create an interactive user interface. It brings together the speed of JavaScript with a new way of rendering webpages, making them dynamic and responsive to user input.

This is why ReactJS front-end developers are so much in demand. Their skills with this framework create quality interfaces. The best ones have:

  • Proficiency in JavaScript and object modelling
  • Knowledge of ReactJS and its core principles
  • Experience in popular workflows such as Flux or Redux
  • Familiarity with specifications of scripting languages

Reasons for the Popularity of ReactJS

ReactJS was one of the first JavaScript-connected projects. It was initially released as open-source by Facebook.

  • A recent developer survey showed that almost 70% felt that it was the most loved framework.
  • Its popularity has only grown with time, with almost 65% saying that they have used it and would love to do so again.
  • One market share study shows that 1,128,346 websites and 289,318 unique domains use it all over the world.

Most Loved Technologies - reactjs front-end developer

Unlike other frameworks, ReactJS doesn’t use a model-view-controller structure. Instead, it encourages the developer to work with reusable UI components. This is ideal for presenting data that changes over time.

This flexibility is why it has been quickly adopted. It has several advantages:

  • It can render views, not templates. These abstractions are important in the case of large applications
  • It can make views easier to maintain because it unifies the markup with corresponding view logic
  • The seamlessness of ReactJS means there’s no need to concatenate strings manually. This leads to fewer vulnerabilities
  • When changes in data are called for, there are only a minimal set of code alterations needed. This downward data flow makes it more stable

ReactJS also has all the advantages of free access. There are several useful applications and additional tools from off-company developers.

In this way, the lightweight and dynamic nature of React JS makes it the preferred choice for front-end development.

Why It’s Hard to Find Good ReactJS Front-end Developers

ReactJS makes it possible to create compelling and immersive interfaces that companies need in order to be noticed online. As such, ReactJS developers are in great demand.

As it was introduced by Facebook only in 2013, most people have limited experience in ReactJS. It is based on JavaScript, and it is simple to learn, but that doesn’t mean it’s easy to gain proficiency.

Typically, such developers are already working with companies and start-ups that have seen the value of ReactJS and are keen to capitalise on it.

Some of these are: Facebook, Dropbox, Khan Academy, Netflix, Airbnb, PayPal, Walmart, and Tesla Motors. In addition, there are many current apps that also use ReactJS.

All of this means that a proficient ReactJS front-end developer is in an enviable position. He or she is likely to be snapped up quickly by a well-regarded company, in a fulfilling position.

Hire Dedicated Front-end Experts

In fact, studies show that the annual average ReactJS developer salary is USD 72,681 in the United States, and GBP 36,097 in the United Kingdom. In India, it is approximately INR 5,61,606 for a developer to INR 10,68,760 for a technology lead.

Careful. Not All ReactJS Front-end Developers are the Same

You can certainly come across people who know JavaScript and also have some experience with ReactJS. Before you rush to work with such developers, there are some things you should know.

For starters, here are some of the skills that good ReactJS developers should possess:

  • They should be able to work with semantic HTML tags, CSS selectors, and understand the box model
  • They should have experience working with JSX, an indispensable part of ReactJS
  • They should understand Ecma Script 6, with its variables, arrays, and functions, among others.
  • Redux is a state management library, and mastering its principles is key to good front-end development with ReactJS

It’s clear, of course, that a professional and experienced JavaScript developer will be more skilled with ReactJS. It’s also important for such a person to have exposure to front-end development, which not all of them have.

For these reasons, you should make sure that the ReactJS front-end developer you’re thinking of hiring is really the right choice. They have varying levels of experience and expertise.

The Consequences of Choosing the Wrong ReactJS Developer

The time taken to hire just the right developer can cause anxiety levels to rise. However, choosing the wrong one can lead to very unfortunate results.

These are some of the issues that can crop up:

Issues of Authentication and Authorisation: These are critical in today’s security-conscious time. If such concerns are not handled properly, the company information and operations could be at risk.

Issues of Scalability: Once the operation grows, it’s a waste of time and effort to rewrite parts of the application. These need to be built-in from the start so that scalability does not turn into a web development problem.

Issues of SEO: As with scalability, proper SEO ought to be kept in mind from the start. Too often, an inexperienced developer will leave this for the final stages, when content is created. Sometimes, this can mean that large parts of the system need rewriting.

Issues of Bandwidth: When it comes to development and testing, fast connection speeds are the norm. But this may not be the case in a real-time consumer environment. If not addressed, this leads to frustration.

Issues of Screens and Browsers: Today’s customer accesses the web in a variety of ways. There are tablets, mobile phones, and desktops, and there are also a variety of web browsers. The front-end development needs to optimise for all of these.

The Solution: Hiring Offshore Front-end Developers

As you’ve just seen, ReactJS is a great way to render your webpages. Its popularity means that good developers are hard to come by, and choosing the wrong one could lead to undesirable consequences.

Is there a way out? Yes, there is. All you need to do is look at on-boarding an efficient team of offshore developers, such as Uplers.

There are several advantages to this. Among them are:

  • Access to a global talent pool
  • Working with developers who have the experience and expertise to suit your needs
