[Updated] Best Javascript Frameworks from 2018-2019

With the wave of digitization, web development is rapidly evolving. Every year we see many new frameworks and platforms for application development, each with their unique benefits. However, in order to build a better audience and improve inbound sales, you need to identify which framework is best as per your requirements. 

Based on our onsite and offsite web development experiences for B2B clients, I’ll list down the best Javascript framework from 2019, which you should know to stay ahead of the competition.

Best Front-end Javascript Frameworks

1. Vue.js

It is relatively new but gaining a lot of traction among the community of developers. Vue.js works with the MVVM design paradigm and has a very simple API. It demonstrates minimalism to the extreme and allows you to use selective modules as per your requirements. Inspired by AngularJS, ReactJS, knockoutJS and RivetsJS, Vue.js updates model and view via two-way data binding.

While Vue is not in the league of Angular or Ember, but conceptually it has all the potential to be the JavaScript framework of the future and hold respectable market share. It is holding the ground firmly after 10 months of its release and getting regular updates by the creator, Evan You. Vue.js has been declared as the most popular front-end JavaScript framework on GitHub with 40K stars.

Details – vuejs.org

2. AngularJS

AngularJS, the baby of Google, is the big daddy of JavaScript frameworks. It currently boasts the biggest community of developers and is also the most used JavaScript framework for developing Single Page Web Applications. 

AngularJS framework gives superpowers to HTML by adding all the necessary features required to build dynamic views (interactive user interface).

It gives the option to extend HTML attributes by the use of Angular directives. Two-way data binding is at the core of AngularJS. This essentially takes away all the pain of writing manual code for DOM manipulation. 

Angular 2’s final version was released in 2016. It was completely re-written, also focused on mobile apps development and was a big success. From 2016 to 2018 it has graduated further to Angular 6 as a great improvement over old. After the release of Angular 7 in October 2018, it became the most preferred framework for enterprise-level apps.

On May 28, 2019, Angular 8 was released featuring differential load for all application code, dynamic imports for lazy routes, and Typescript support. Now, Angular is integral to the MEAN stack for web application development.

3. React

Developers might have noticed that React is the user interface behind Facebook and Instagram. This gives us a quick idea about how powerful React is for building large-scale applications of extremely dynamic nature. 

React framework is best at rendering complex user interfaces with high performance. It deploys the concept of virtual DOM (Document Object Model). React utilizes a virtual DOM, which you can render at the client-side or server-side and communicate back and forth.

The community is growing rapidly ever since its release and I must say it is the fastest-growing JavaScript framework as of today. One can find tons of resources, tutorials and React component libraries to get going within no time.

4. Ember.js

Ember.js is another powerful MVC Javascript framework. Many popular websites like Discourse, Groupon, LinkedIn, Vine, Live Nation, Nordstrom, Twitch.tv, and Chipotle use Ember. Although primarily considered a framework for the web, it is also possible to build desktop and mobile applications in Ember. The most notable example of an Ember desktop application is Apple Music.

EmberJS competes with the likes of AngularJS and React when it comes to building interactive frontend user interfaces. It also has a very active community of developers. 

Ember rides on the principle of two-way data binding like AngularJS. It targets the best of both AngularJS (two-way data binding) and React (server-side rendering).

Best Javascript Frameworks for Backend development

1. Express

When you google for Node.js frameworks, surely you might have come across Express very often. Express.js is among the top Node.js frameworks. It is an efficient platform for building robust applications and APIs. Express is also one of the four components of the popular MEAN stack (MongoDB, Express, AngularJS, and Node.js) for web application development. Here, Express serves as a middleware between the front-end, database, and back-end of an application.

Express is very flexible and lightweight and offers excellent possibilities in terms of using plugins, extensions and third-party databases. People often refer to Express as the server framework for Node.js as it creates an HTTP server for Node.js and supports the middleware functionality to respond to the HTTP requests. It has a superb set of documentation and enjoys great community support.

Details – expressjs.com

2. Sails.js

To build custom, enterprise-grade Node.js apps, Sails.js is a great fit. It mimics the MVC pattern of frameworks like Ruby on Rails but with support for the requirements of modern apps (i.e. data-driven APIs with scalable & service-oriented architecture). It is especially suitable for building chat, real-time dashboards, or multiplayer games.

Details – sailsjs.com

Last but not the least:

Meteor

Meteor is the magical isomorphic full stack platform for building an end to end mobile and web applications completely in JavaScript at a lightning fast speed. Isomorphic Javascript is also known as Universal Javascript defines the JS applications which run on both client and server. It is the power player, equipped with all the features you need for frontend rendering, backend development, business logic and database management. 

The best thing about MeteorJS is that you use only JavaScript for an end to end application development, no need to invest time learning anything else. It is modular and you can use packages and libraries on demand basis. The server-side packages run in the Node.js and you do not need anything else but Meteor packages to access the database, all in JavaScript! This makes Meteor applications real-time web applications.

How Smarter Sales Apps Are Reinventing the Frontlines of Insurance Distribution

The insurance industry thrives on relationships—but it can only scale through efficiency, precision, and timely distribution. While much of the digital transformation buzz has focused on customer-facing portals, the real transformation is happening in the field, where modern sales apps are quietly driving a smarter, faster, and more empowered agent network.

Let’s explore how mobile-first sales enablement platforms are reshaping insurance sales across prospecting, onboarding, servicing, renewals, and growth.

The Insurance Agent Needs More Than a CRM

Today’s insurance agent is not just a policy seller—they’re also a financial advisor, data gatherer, service representative, and the face of the brand. Yet many still rely on paper forms, disconnected tools, and manual processes.

That’s where intelligent sales apps come in—not just to digitize, but to optimize, personalize, and future-proof the entire agent journey.

Real-World Use Cases: What Smart Sales Apps Are Solving

Across the insurance value chain, sales agent apps have evolved into full-service platforms—streamlining operations, boosting conversions, and empowering agents in the field. These tools aren’t optional anymore, they’re critical to how modern insurers perform. Here’s how leading insurers are empowering their agents through technology:

1. Intelligent Prospecting & Lead Management

Sales apps now empower agents to:

  • Prioritize leads using filters like policy type, value, or geography
  • Schedule follow-ups with integrated agent calendars
  • Utilize locators to look for nearby branch offices or partner physicians
  • Register and service new leads directly from mobile devices

Agents spend significantly less time navigating through disjointed systems or chasing down information. With quick access to prioritized leads, appointment scheduling, and location tools—all in one app—they can focus more on meaningful customer interactions and closing sales, rather than administrative overhead.

2. Seamless Policy Servicing, Renewals & Claims 

Sales apps centralize post-sale activities such as:

  • Tracking policy status, premium due date, and claims progress
  • Sending renewal reminders, greetings, and policy alerts in real-time
  • Accessing digital sales journeys and pre-filled forms.
  • Policy comparison, calculating premiums, and submitting documents digitally
  • Registering and monitoring customer complaints through the app itself

Customers receive a consistent and seamless experience across touchpoints—whether online, in-person, or via mobile. With digital forms, real-time policy updates, and instant access to servicing tools, agents can handle post-sale tasks like renewals and claims faster, without paperwork delays—leading to improved satisfaction and higher retention.

3. Remote Sales using Assisted Tools

Using smart tools, agents can:

  • Securely co-browse documents with customers through proposals
  • Share product visualizations in real time
  • Complete eKYC and onboarding remotely.

Agents can conduct secure, interactive consultations from anywhere—sharing proposals, visual aids, and completing eKYC remotely. This not only expands their reach to customers in digital-first or geographically dispersed markets, but also builds greater trust through real-time engagement, clear communication, and a personalized advisory experience—all without needing a physical presence.

4. Real-Time Training, Performance & Compliance Monitoring

Modern insurance apps provide:

  • On-demand access to training material
  • Commission dashboards and incentive monitoring
  • Performance reporting with actionable insights

Field agents gain access to real-time performance insights, training modules, and incentive tracking—directly within the app. This empowers them to upskill on the go, stay motivated through transparent goal-setting, and make informed decisions that align with overall business KPIs. The result is a more agile, knowledgeable, and performance-driven sales force.

5. End-to-End Sales Execution—Even Offline

Advanced insurance apps support:

  • Full application submission, from prospect to payment
  • Offline functionality in low-connectivity zones
  • Real-time needs analysis, quote generation, and e-signatures
  • Multi-login access with secure OTP-based authentication

Even in low-connectivity or remote Tier 2 and 3 markets, agents can operate at full capacity—thanks to offline capabilities, secure authentication, and end-to-end sales execution tools. This ensures uninterrupted productivity, faster policy issuance, and adherence to compliance standards, regardless of location or network availability.

6. AI-Powered Personalization for Health-Linked Products

Some forward-thinking insurers are combining AI with health platforms to:

  • Import real-time health data from fitness trackers or health apps 
  • Offer hyper-personalized insurance suggestions based on lifestyle
  • Enable field agents to tailor recommendations with more context

By integrating real-time health data from fitness trackers and wellness apps, insurers can offer hyper-personalized, preventive insurance products tailored to individual lifestyles. This empowers agents to move beyond transactional selling—becoming trusted advisors who recommend coverage based on customers’ health habits, life stages, and future needs, ultimately deepening engagement and improving long-term retention.
