Well, it will help you plan your growth and innovation strategies to take on the competitive challenges. With this blog, you will be paving your path to understand the complex roadmap to web application development. 

From practical insights to step-by-step processes adopted by professionals, this blog will be your comprehensive guide to web app development. 

What is Web Application Development?

In simple words, web application development is the approach, referring to the process of designing, developing, testing, and launching dynamic apps that are accessible through web browsers. 

The web applications are integrated or installed onto the remote servers and executed through server-side or client-side programming. Users don’t have to install the web apps on their devices. Instead, they can simply use their internet browsers for seamless accessibility. 

Professionals working on web app development projects often use technologies such as JavaScript, CSS, HTML, Django, Node.js, and others. Beyond that, web applications are also built using sophisticated architectures, ensuring seamless usability and functionality. For instance, companies like Dashdevs often take this approach, helping businesses shape software that are not only functional but also flexible enough to grow with their needs.

A web application can be a simple website or a complex software solution, depending on your unique business needs. 

What are the Different Types of Web Apps?

Before getting along with the different types of web apps you should know, it is important you understand what they actually are. 

A web application, or commonly referred to as a web app, is a software program designed to provide interactive functionalities to Internet users. Every web app serves the unique purpose of representing the associated brand and adhering to the respective needs. But at the helm of everything that a web app does, the aim is to offer satisfactory user experiences. 

Now, to help you better understand what is web application development, here are some of the different types of web apps you can consider for your brand needs:

1. Single Page Applications (SPA)

You might have come across websites like Facebook or Gmail! Have you noticed that the content on those web pages loads without the need for frequent refreshing? Well, that’s single-page applications for you! 

SPAs serve the purpose of delivering a seamless and fast experience with dynamic parts that update themselves, responding to users’ interactions. This way, users get the feeling of using a desktop application when they are simply visiting a website on a browser. 

An SPA can ensure faster loading, reduced server load, and seamless user experience. You must consider single-page web applications if you want a responsive and quick app, freeing users from the hassle of navigating through multiple web pages. 

2. Multi-Page Applications (MPA)

To give you an example, think of websites like eBay or Amazon. Every time you select a product from their landing pages, you are redirected to an entirely different webpage. It is because they are multi-page applications. 

Multi-Page Applications, or MPAs, might not be as fast as SPAs, but they are ideal for content-heavy business platforms. The benefit of having multi-page applications is, they can deal with larger datasets and complex interactions. 

If you are a brand facing the need for in-depth content management, while ensuring the platform offers rich UI, adopting MPAs can be an ideal pick. 

3. Progressive Web Applications (PWA)

If you want web applications that can guarantee top-notch speed and seamless accessibility, PWAs can be your go-to option. Websites like Pinterest are a fine example of PWA. The purpose of progressive web applications is to work fine even with weak internet, which is made possible using cached data. 

The best part of a PWA is, it feels like using a native app with offline access and push notifications. Mobile-friendliness is a key USP of progressive web applications, alongside faster loading times and offline functionality. 

If you are willing to give your target audience a native app-like experience without urging them to make App Store or Play Store downloads, progressive web application development is your thing. 

4. Rich Internet Applications (RIA)

The purpose of RIAs is to offer users a desktop-like experience, even when they are using just a web browser. Some fine examples of it are Adobe Flash apps and Google Docs. 

The rich internet applications are mostly popular for their interactive features, such as drag-and-drop interfaces and real-time collaboration. You can expect top-notch visual engagement from your site users and enhanced interactivity. 

If you are dealing with a business that might need real-time updates and constant brand-user interactivity, RIAs can be your ideal pick. 

Examples of Appealing Web Apps for Your Inspiration

If you want some inspiration to set expectations for your web app development project, here are some examples for you to explore and assess:

1. Netflix, Airbnb, Trello, Gmail, and Google Maps are examples of some of the best Single-Page Applications ever built.
2. Web apps like those of Amazon, eBay, Twitter, Facebook, and The New York Times are a few examples of Multi-Page Applications.
3. Some of the popular PWAs across the internet that can actively inspire you for your project are Pinterest, Starbucks, Uber, Spotify, Financial Times, and others.
4. When talking about RIAs, you can consider games like World of Warcraft, or online platforms/tools like Slack, Adobe Premiere Pro, and Adobe Premiere Rush.

Benefits of Adopting Web Application Development

If you are starting off your new business and want to make an online presence, having a web application should be the initial move. But, how will it benefit you? Is it absolutely necessary to consider web application development for attaining customer satisfaction and trust?

Well, here are some of the benefits of seeking web application development for your business needs to help you understand its importance:

1. Seamless Accessibility:

You won’t have to encourage your users to download native mobile apps on their phones. Instead, you can just create a mobile-friendly web application and make it seamlessly accessible across all internet browsers. 

2. Frequent Updates Necessary:

Unlike mobile apps, web applications don’t need frequent updates, which ensures there will be less or no downtime for users. Thus, your brand web app will always be accessible for users, giving you more traffic, conversions, and sales. 

3. Enhanced Security:

Professionals integrate advanced security solutions such as user authentication, data encryption, and more to protect the business data on web applications. Therefore, potential risk mitigation becomes easier with web applications. 

4. Business Scalability:

With web applications, you can easily scale your business to accommodate the increased data volumes and growing user bases. Such flexibility is what will help you seamlessly expand your business services without the need for extensive infrastructure modifications. 

5. Cost-Effectiveness:

With the right team of professionals taking care of your enterprise web application development projects, you can attain the utmost cost-effectiveness. When, compared to traditional desktop apps, web applications demand low initial investment and are also easier to update and maintain. 

Step-Wise Approach for Web Application Development

If you are to hire a team of professionals to help you with your web-based application development projects, here is a step-wise approach they would adopt for the same:

Step 1: Choose the Ideal Type of Web App

Experts will take your preference on the type of web application you want to build for your brand or business. Apart from SPAs, MPAs, and PWAs, there are also other types of web applications based on the functionality and UI differences that you can count on. 

For instance, you can consider having an e-commerce store, an animated web app, CMS apps, or others. Upon choosing the right type, you will eventually be able to attain success for your web app development project. Experts will help you in the process!

Step 2: Picking the Right Technology Stack for Web Application Development

Once you have decided on the type, the next step is picking the right tech stack for the web application development process. Experts you hire will provide you with the frontend, backend, and database technology options to choose from. Beyond that, they will also guide you on the capabilities of all the tech stacks available. 

Some of the frontend, backend, and database technologies you can choose from are:

Frontend:

• React
• Vue.js
• Angular
• Flutter

Backend:

• Node.js
• Python
• Java
• .NET
• PHP

Database:

• MySQL
• MongoDB
• PostgreSQL

Hosting Environment

• AWS
• Azure
• Google Cloud
• Conventional hosting like Rackspace, Bluehost

Analytical Tools

• Firebase
• Google Analytics
• NewRelics

If you are not sure about which tech stack seems ideal for your web application development project, seek expert guidance to make an informed decision. 

Step 3: Choose an Ideal Hiring Model

Your web application development company will then request you to pick your ideal business model based on your unique requirements. There are three popular hiring models that are commonly preferred by business owners for curating their web apps, which include:

1. RaaS (Resources as a Service)

It is a monthly business model where you are liable for hiring resources such as designers, testers, developers, and other professionals to work specifically on your project. 

There are basically three engagement options in this business model: onshore, offshore, and offshore development centers. Consider your suitability and pick the right business model. 

2. Time and Material

Considering this business model for your web app project is suitable only when you don’t have a clear project scope. It means that if your web app might need frequent modifications in the long run, it is better to pay the professionals on an hourly basis. 

Thus, it is a flexible option for you to implement the evolving requirements into your web app project. When you have an open-ended web app project, it becomes difficult to estimate the workload in advance. In that case, this business model can be effective!

3. Fixed Price

If you have a well-defined web-based application development project with clear & concise requirements, adopting a fixed price hiring model can be effective. In this, both parties will be signing an agreement that would highlight the scope of work and a pre-decided cost. 

It is a risk-free model for anyone who is budget-conscious and wants transparency with respect to the upfront costs. 

Step 4: Front-End Development

Experts will now be taking over the core web app development tasks, starting with the front end. This part of your web app will be responsible for everything that the users see or interact with. For instance, it will have UI components, content structure, dynamic features, and other such attributes that would enhance the overall user experience. 

The developers prefer using technologies like HTML, CSS, and JavaScript for crafting the front end of a web app. HTML gives a structure to your web page and defines elements like images, paragraphs, links, and headings. On the other hand, CSS is used for seamless layout control and styling. Developers get to apply fonts, colors, and HTML positioning with it.

JavaScript is responsible for handling the interactivity and dynamic content modifications. Right from validation to asynchronous data fetching, developers prefer using JavaScript to serve the purpose. React, Angular, React.js, and Vue.js are some frameworks that support developers to integrate powerful functionality into their web apps. 

Step 5: Back-End Development

Back-end is better understood as the engine that runs your web application. It is responsible for managing databases, processing requests, and ensuring everything works smoothly. Back-end development is built on server-side logic. It means, whenever a user engages with the front-end of your web app, the back-end is responsible for executing that request. 

For instance, if a user submits a login form, the back-end will then verify the details and send an appropriate response. Experts make use of Python, Ruby on Rails, PHP, or Node.js in order to tailor the back-end of a web application.

Step 6: Database Development

You ought to have a system in place that can manage the web app’s data in the back-end. A web application might store content, user profiles, transactions, and other such data that can be retrieved or organized efficiently. 

Therefore, the professionals you hire for your custom web application development project will use a dedicated database like MySQL, MongoDB, or PostgreSQL to serve the purpose. Handling complex queries and large data volumes can be made easier with the choice of the right databases for your web application. 

Step 7: Testing

The next step that your web application development company will preferably adopt is testing. Here, your web application will be tested across different parameters such as functional, performance, security, end-to-end, integration, and others. 

There are basically two approaches, manual and automated testing, for validating the performance of your web application. Top professionals in the industry, like the ones Simpalm offers, prefer combining manual and automation testing approaches for a hybrid and more efficient approach. 

Some of the top testing tools or frameworks preferred for the purpose are:

• Katalon
• Selenium
• Cypress
• BrowserStack: used to test the web for combinations of different browsers and operating systems.

Step 8: Compliance and Security Testing

Before moving on to the deployment phase of your web application, security and compliance testing are an inevitable step. It is important in order to protect the sensitive data of your business against constantly growing cyber attacks. Not just that, but it helps experts identify potential vulnerabilities and associated risks, which they can mitigate before deployment. 

The professionals you hire will ensure your web application is compliant with the regulations such as HIPAA, PCI-DSS, SOC2, GDPR, and ISO. Under these regulatory compliances, you will be required to protect the sensitive data on your web application and also demonstrate that it is backed up with advanced security tools. 

Some of the different types of security testing approaches adopted by expert web application developers are:

• Static Application Security Testing (SAST)
• Runtime Application Self-Protection (RASP)
• Penetration Testing
• Dynamic Application Security Testing (DAST)

Step 9: Deployment Phase

Now, your web app is developed and ready to go live. It is the stage where you must impose careful planning to ensure everything works smoothly once the web app is deployed. Earlier, web apps were deployed by manually transferring the files to a dedicated server. But now, there are CI/CD pipelines and automated deployment tools to make the process more reliable.

Once the web application is live, the team of developers and associated professionals will monitor its performance and track any initial errors. Post-launch maintenance and timely updates are essential to ensure high uptime and consistent performance for your web app. 

Factors that Affect the Cost of Web Application Development

Now that you have a clear idea about the process of custom web application development, the next obvious question you might have in mind is, what would it cost to hire professionals?

When you are starting off with a new business idea, the web application development cost is a crucial aspect to take note of. But, there is no fixed price tag to it! There are several factors that impact the overall cost of web application development, including:

1. Project Complexity

Whether you want simple go-to features for your web app or complex functionality elements, the cost will reflect the impact of your choices. For instance, if you just need a login function, a simple UI, and a couple of navigation options, the overall cost of developing a web application will be low. 

But if you need advanced technology-backed features for your web app, such as 3D animations, AI integration, or more, the overall cost will increase. 

2. Cost of Hiring Professionals

The web application development company you hire will also be charging you, based on the hiring model you opt for. You will have a dedicated team of professionals working solely on your project.

Depending on what your project complexity range is, you can appoint junior, mid-level, or senior developers to take up your project. The overall cost of web application development will depend on the skill and experience level of the team you hire.
