Salesforce introduced Lightning Web Components (LWC) in December 2018, which has moved this Salesforce platform a step closer to using web standards for UI development. Developers with basic knowledge of Visualforce Pages can start working with LWC without correctly understanding Lightning Components. LWC uses modern Javascript Frameworks. As a result, any developer who has knowledge of Node.JS or React. JS can easily code in the LWC  platform. 

Though Aura and LWC can co-exist in the ecosystem, developers are more interested in migrating the Aura Framework to Salesforce LWC. So they are seeking to know the benefits and functionalities associated with this new component.  

This article, CloudVandana, will discuss the differences between Aura Component and Salesforce LWC

Following are the differences in features between the two-component to make development easy and increase business value. 

Use Of Native Browser APIs

Since the introduction of Lightning Experience, the component is continuously contributing to web standards. As per the evolution of web standards, browser vendors implement them in native browser APIs. Salesforce keeps changing the functionalities to meet with significant browser vendors for priorities alignment. 

Aura framework used a proprietary component model, language extensions, and modules, but LWC uses web stack features that browsers implement natively. So it is clear to state that LWC web apps are substantially more effective. 

Uses Moden Javascript Framework

Javascript includes various frameworks such as modules, classes, promises, template literals, decorators, etc. LWC supports all these Javascript features. Javascript is not only a powerful scripting language but also has a considerable contribution to server-side development. The typical web standards properties in LWC make it easier to find developers with Javascript technology expertise. 


As Salesforce LWC is an open-source platform capable of aligning with web standards, it can quickly work outside the platform. For example, developers can write a component on the platform and reuse that component somewhere else. 

Backward Compatibility

Developers don’t need to worry about backward compatibility while deploying LWC-based web applications to a larger audience across browsers. 

Why Developers Should Choose LWC Instead of Aura Components

Better Functionality

No abstraction layer is added to LWC; this component renders faster than the Aura component and provides enhanced performance. 


LWC  adopts native web standards, so it does not require any extra layer like Aura Framework, as we discussed before. Its development only depends on standard Javascript. So developers can quickly adopt this component without any complexity. Developers do not need any additional framework to develop LWC, so the transition is more straightforward. 

Faster Loading

It is a lightweight framework built on web standards. So LWC is faster in loading than Aura components. 

Service Components

Developers can write components that have no user interface in LWC. Then, later on, those components can be reused in other components. 

There are various other differences between the Aura component and LWC. An experienced LWC developer can guide an organization with the best practices. CloudVandana, the renowned Salesforce partner, has launched a new service, “ LWC Developers as a Service.” Organizations can hire Unlimited LWC Resources at a flat rate. Sounds interesting?
