A Complete Guide To Single Page Application Development (SPA)

Why Invest in Single Page Application? How to Hire Developers to Build A Single Page Application? What is the cost of Single Page Application Development?

Who doesn’t cherish a fast and responsive website that doesn’t take hours to load the page? Hours are an exaggeration, but even minutes seem like hours when you are in a hurry to view any information, product, or service.

And any business that wants to deliver a smooth user experience must consider developing a single page web app. Why? SPAs can load any information in a breeze, so why not?

If it feels superficial to you, wait till we explore everything about SPAs before you have to invest in its development. So, without further ado, let’s learn about single page application development and make some good decisions.

Defining Single Page Applications (SPAs)

A single page application is a web app directly delivered to the browser that doesn’t need page reloading when used. These web apps fit in one HTML web page that acts as a shell for all the other web pages. Unlike traditional web apps focusing on 2-tier and 3-tier architecture, single page applications operate on client-side architecture.

In simple terms, SPAs initially load one HTML page and then dynamically update the content based on user interactions with the web app. Some prevalent examples of SPAs we use in our day-to-day lives are Netflix, Facebook, Gmail, Twitter, Google Maps, GitHub, Pinterest, Airbnb, PayPal, and Google Drive.

Single page applications also help reduce the repetition of the same code on multiple pages, provide a desktop-like experience on the web, make progressive web app development faster, hold caching capabilities, come with cross-platform compatibility, and have better UI/UX.

Why Invest in Single Page Application?

With a better understanding of single page applications, let’s dive into the reasons why an organization should invest in one.

• Enhanced Load Speed

• Caching Power

• Faster Development

• Easier Bug Fixes

Enhanced Load Speed

Single Page Applications, or SPAs, are designed to update only the necessary parts of the web page, instead of reloading the entire page, resulting in faster page loading speed and quicker response to user requests.

This is achieved by loading most of the resources required for the SPA, such as HTML, CSS, and JS, only once, and then changing the data when requested. As a result, businesses can benefit from shorter wait and load times, which makes the user experience faster and more efficient.

Caching Power

Caching is storing copies of files in temporary storage for quick access. Single page applications have incredible caching capabilities to help fast page load speed and reduce bandwidth usage. This allows SPAs to show pages even in faulty or disrupted internet connections.

Faster Development

Developing a single page application is much easier as it has a decoupled setup, i.e., a separate frontend and backend. This decoupled setup allows developers to develop, maintain, and update the front end and back end of the website without interfering with the other, leading to faster and more efficient web app development.

Easier Bug Fixes

SPAs can be easily debugged using Chrome’s developer tools. It allows developers to check the code rendering from the browser, detect bugs, errors, and security vulnerabilities, and debug them to eliminate sluggish performance.

Cross-Platform Compatibility and Cost-Effective

As SPAs have a single codebase, developers can easily build web apps that can run on any browser, device, and operating system, leading to a seamless user experience through easier accessibility across devices. Not only that, but it also eliminates the need to develop the web app for different platforms which costs thousands of dollars, making SPAs cost-efficient.

How to Hire Developers to Build A Single Page Application

To develop a single page application, you need to hire developers, but the question is how? Therefore, we have shared some key points to consider before hiring developers for the project as follows:

Create a Budget

Initially, you need to come up with a budget for how much you want to spend on the project before hiring developers from a software development company. You need to determine how much you are willing to pay for all the costs including domain hosting, tech stack, number of resources, third-party integrations, etc. that come with SPA development.

Research Different SPA development companies

Once you have set the budget limit, the next step involves doing market research and determining top companies for single page app development. While doing so, ensure an overview of the experience, portfolio, and reviews of their past projects to find the ideal choice.

Determine the Employment Model

After enlisting the top choices, the next step involves the employment model for outsourced developers. Whether you want to hire developers in a project-based model or a dedicated team model depends on the requirements you have in mind.

For instance, if you are working on a small project, then the project-based model will work the best for you as you have to pay a fixed price decided at the beginning, however, if you want to develop the SPA from the ground up then the dedicated team model will work the best as the development team will exclusively work on your project for a specified time, providing better flexibility.

After receiving their responses, you can compare the timelines, costs, processes, and resources, ask additional questions, set up interviews then select the company you want to work with.

Sign the contract

When you are satisfied with the experience of the development company’s professionals, you can outline the project terms of agreement and expectations, explaining the purpose, timeline, deliverables, payment terms, schedules, and termination clause. Then sign the contract after mutual agreement from both parties and start working on the project.
