7 Best Techniques to Boost AngularJS Applications Performance

2 minutes, 13 seconds read

AngularJS is a highly versatile framework and it can be used to build almost any type of web application. Some of the popular web AngularJS applications are — Netflix, LEGO, UpWork, YouTube for PS3, PayPal, Gmail, and The Guardian. Although, AngularJS is capable of handling high volumes of traffic, still, you can skyrocket applications performance by following these measures-

Infographic - Improve AngularJS Applications performance

1. Avoid using too much of watchers/data bindings

Any time we introduce more data-bindings, we create more $$watchers and $scopes. It prolongs the digest cycle. Too many $$watchers can cause lag. That’s why you should limit their use as much as possible. One needs to keep a check on the digest cycle. To understand this better, consider each digest cycle as a loop that monitors the changes to variables. The shorter the digest cycle, the faster the application will run.

2. Use native JavaScript or Lodash

Lodash improves your application performance by simply re-writing some of the basic logic instead of relying on inbuilt AngularJS methods. Built-in Angular methods mostly account for generic use cases.

3. Minimize the DOM access

Accessing the DOM very frequently could get expensive, so keep your DOM trees small. Don’t modify the DOM if you can help it, and don’t set any inline styles to avoid JavaScript reflow.

4. Use ng-if instead of ng-show/ng-hide

ng-show directive toggles the CSS display property on a particular element while ng-if directive actually removes the element from DOM and re-creates it (if required). Further, ng-switch directive is an alternative to ng-if for the same AngularJS application performance benefits.

5. Ensure proper Bundling and Minification

Bundling and minifying website scripts and stylesheets reduce page load time and asset size. For Bundling and Minification of code at the time of deployment, you can use several task runners available like gulp or grunt.

6. Use $watchCollection instead of $watch

$watch with only 2 parameters is faster. However, Angular also supports a 3rd parameter to this function, that can look like this: $watch(‘value’, function( ){ }, true). The third parameter tells Angular to perform deep checking (i.e. to check every property of the object), which could be very time taking. Thus, for more than 2 parameters, use $watchCollection.

7. Use Chrome DevTools like CPU Profiler and Timeline

A general browser-related technique is to use both the browser devTools Profiler and the Timeline tool. It can help you find performance bottlenecks to guide your optimization efforts.

Retention playbook for Insurance firms in the backdrop of financial crises

4 minutes read

Belonging to one of the oldest industries in the world, Insurance companies have weathered multiple calamities over the years and have proven themselves to be resilient entities that can truly stand the test of time. Today, however, the industry faces some of its toughest trials yet. Technology has fundamentally changed what it means to be an insurer and the cumulative effects of the pandemic coupled with a weak global economic output have impacted the industry in ways both good and bad.

For instance, the U.S market recorded a sharp dip in GDP in the wake of the pandemic and it was expected that the economy would bounce back bringing with it a resurgent demand for all products (including insurance) across the board. It must be noted that the outlook toward insurance products changed as a result of the pandemic. Life insurance products were no longer an afterthought, although profitability in this segment declined over the years. Property-and-Casualty (P&C) insurance, especially motor insurance, continued to be a strong driver, while health insurance proved to be the fastest-growing segment with robust demand from different geographies

Simultaneously, the insurance industry finds itself on the cusp of an industry-wide shift as technology is starting to play a greater role in core operations. In particular, technologies such as AI, AR, and VR are being deployed extensively to retain customers amidst this technological and economic upheaval.

Double down on digital

For insurance firms, IT budgets were almost exclusively dedicated to maintaining legacy systems, but with the rise of InsurTech, it is imperative that firms start dedicating more of their budgets towards developing advanced capabilities such as predictive analytics, AI-driven offerings, etc. Insurance has long been an industry that makes extensive use of complex statistical and mathematical models to guide pricing and product development strategies. By incorporating the latest technological advances with the rich data they have accumulated over the years, insurance firms are poised to emerge stronger and more competitive than ever.

Using AI to curate a bespoke customer experience

Insurance has always been a low-margin affair and success in the business is primarily a function of selling the right products to the right people and reducing churn as much as possible. This is particularly important as customer retention is normally conceived as an afterthought in most industries, as evidenced in the following chart.

AI-powered tools (even with narrow capabilities) can do wonders for the insurance industry at large. When architected in the right manner, they can be used to automate a bulk of the standardized and automated processes that insurance companies have. AI can be used to automate and accelerate claims, assess homeowner policies via drones, and facilitate richer customer experiences through sophisticated chatbots. Such advances have a domino effect of increasing CSAT scores, boosting retention rates, reducing CACs, and ultimately improving profitability by as much as 95%.

Crafting immersive products through AR/VR

Customer retention is largely a function of how good a product is, and how effective it is in solving the customers’ pain points. In the face of increasing commodification, insurance companies that go the extra mile to make the buying process more immersive and engaging can gain a definite edge over competitors.

Globally, companies are flocking to implement AR/VR into their customer engagement strategies as it allows them to better several aspects of the customer journey in one fell swoop. Relationship building, product visualization, and highly personalized products are some of the benefits that AR/VR confers to its wielders.  

By honoring the customer sentiments of today and applying a slick AR/VR-powered veneer over its existing product layer, insurance companies can cater to a younger audience (Gen Z) by educating them about insurance products and tailoring digital delivery experiences. This could pay off in the long run by building a large customer base that could be retained and served for a much longer period.

The way forward

The Insurance industry is undergoing a shift of tectonic proportions as an older generation makes way for a new and younger one that has little to no perceptions about the industry. By investing in next-generation technologies such as AR/VR, firms can build new products to capture this new market and catapult themselves to leadership positions simply by way of keeping up with the times.

We have already seen how AR is a potential game-changer for the insurance industry. It is only a matter of time before it becomes commonplace.
