JavaScript Technologies for Healthcare SaaS

In 2024, the SaaS industry is going to keep growing. Consequently, we expect growth in the healthcare SaaS industry, too. 

The global healthcare cloud computing market is expected to grow at a CAGR of 17.8% from 2022 to 2027, reaching $89.4 billion by 2027, according to a new report from MarketsandMarkets

The global healthcare cloud computing market expected growth to 2027.

Scalability, cost-effectiveness, and robust security make cloud computing an excellent choice for the healthcare industry. 

Healthcare services providers are rapidly integrating SaaS in their EHR systems, clinical information systems, storage, archiving, remote patient monitoring systems, PACS, population health management, revenue cycle management, analytics, supply chain management, patient-facing web, disaster recovery, and precision medicine.

Unsurprisingly, many of those apps and platforms are built with the help of JavaScript – the most popular choice for web development. 

Healthcare Apps And Platforms Built With JavaScript Technologies 

There are only a few cases. More of them you can find in the next section.  

Cancer Treatment Application

Flatiron Health is a company that specializes in reimagining the infrastructure of cancer care. They provide solutions across the industry to learn from and improve every person’s experience with cancer. 

This platform includes many projects dedicated to cancer research and treatment and sharing the latest insights among professionals. 

Flatiron Assist™ is a clinical decision support platform that helps clinicians choose the right regimens for their patients. It provides real-time, evidence-based treatment options and is customizable to meet the needs of different care settings. 

Like many other Flatiron projects, Flatiron Assist is built using a powerful combination of Node.js and React. React is responsible for a user-friendly and interactive interface. Node.js is an engine that makes big applications still very fast and performative.

Also, they used jQuery to make reactions to user interactions more straightforward and provide a range of optimized effects and animations.

Mental Health Platform

Talkspace is an online therapy platform that offers mental health support to individuals, couples, and teens. They provide access to licensed therapists and psychiatric providers through live video, audio, or messaging sessions. Talkspace also offers medication management and personalized treatment plans.

The Talkspace platform is also powered by Node.js and React. In addition, (a JavaScript library that allows for real-time communication between the browser and the server) ensures the stability and constant updating of the data while messaging and video or audio calls. 

Electronic Health Record System

Cloud-based EHR systems are a special type of healthcare SaaS applications designed to structure and store data about patients.

Practice Fusion is a SaaS platform that provides a cloud-based electronic health record (EHR) system for healthcare professionals. The platform offers a range of features, including charting, e-prescribing, labs and imaging, and practice management, among other functions. 

Digital Hospital

Medbelle is a digital hospital that operates in the UK. 

The website allows patients to book consultations and procedures, access patient stories and reviews, and learn more about the services provided by Medbelle. It also includes a section on patient resources, including information on preparing for surgery, recovering after surgery, and accessing aftercare services.

Except for React and Node.js, this platform is powered by Next.js. Next.js is a library that complements React for even better performance optimization and easier maintenance. 

Since the core feature of the Medbelle platform is scheduling appointments, they use Redux for efficient state management. Redux updates statuses of the time slots and availability of the doctors so patients are not double-booked or properly informed about their appointment status. 

JavaScript Technologies Used in Healthcare SaaS 

JavaScript is not only about one programming language but also about the vast ecosystem of different tools and libraries that can be used to find a perfect solution for every case. 

The X Toolkit

The X Toolkit is a JavaScript library for building web-based applications that require advanced graphics and visualizations. It provides a set of tools for creating 2D and 3D graphics, animations, and other interactive elements.

Surgical Theater is a cloud-based platform for surgical planning that uses 3D graphics and virtual reality to help healthcare professionals plan and visualize complex surgical procedures with detailed 3D models of organs and tissues. It is one of many platforms powered by the X Toolkit. 

AMI Medical Imaging (AMI) JavaScript ToolKit

AMI is a JavaScript toolkit for medical imaging that provides a set of libraries and tools for creating web-based medical imaging applications. It supports various imaging modalities such as X-ray, CT, MRI, and Ultrasound. 

AMI found its place in RTPS (Radiation Therapy Planning Software) to plan and deliver radiation therapy treatments. For example, Varian Medical Systems, a US-based radiation oncology company, uses AMI’s toolkit to provide healthcare providers with a comprehensive radiation therapy planning solution.

Terra UI

Terra UI is a JavaScript library for building user interfaces with React that are fast, accessible, and easy to use. Terra UI was designed by Cerner to meet their needs while developing the Cerner Health platform. 

This platform provides personalized health management solutions for individuals and families. It includes personal health records (storing and managing), connecting with healthcare providers, sharing personal medical information, tracking your health indicators, and much more. 

Many users, especially seniors, might need help managing this huge scope of functionality. That’s why Cerner used Terra UI to make it concise and user-friendly. 


DWV is a JavaScript library for creating web-based data visualizations. DWV can be used to create charts and sheets that help healthcare professionals analyze and understand patient data, progress, or clinical trial results. 

For example, Health Catalyst uses DWV for data analytics for visualization, especially when it comes to depicting multiple dependencies and progress tracking. 

Gaps in the Healthcare SaaS Industry

Although cloud computing in healthcare has been popular for years, there is still space for improvement. The main focus should be shifted from creating new EHRs, which are enough, to creating SaaS applications for hearing and visual impairments. 

The number of platforms for diagnosis and examining hearing impairments is ridiculously small. The same goes for the number of micro-vertical SaaS applications (mainly browser extensions) for enhancing the experience for people with visual impairments, dyslexia, daltonism, or just bad vision.

It seems obvious, but this niche still has a significant gap. 


The Healthcare SaaS industry has been showing steady growth for the past few years and is expected to improve in 2024. As a cornerstone of web development, JavaScript technologies play a crucial role in its growth. 

Various libraries build EHR systems, medical imaging applications, medical research and progress tracking platforms, and much more. Nevertheless, there are always little gaps showing ways to improve the healthcare SaaS industry.
