Lightning Web Components: Game-changing Points in 2019

Share on

In the last decade, many innovations have taken place in the web development world, leading to new web standards. Prominent changes include custom elements, content templates, shadow DOM, and more. Web components allow you to combine User Interface (UI) and processing, but to be able to create a web application, other features like security and access to server data is required. This is where the Lightning Web Component (LWC) comes in. Let’s go over this tool in detail.

What Is Lightning Web Component?

The Salesforce platform leverages these breakthrough developments in web standards and provides developers with web components with additional capabilities (security, lightening data access). It broadly includes 3 major components: the LWC framework (i.e. the engine’s framework), the base lightning components (customer elements as a set of components for easy development of the project), and Salesforce bindings (access to security and data repository).

Specialized Salesforce services include:

Base Lightning Components: A set of 70+ User Interface (UI) components built-in as custom elements that can easily be put during development

Lightning Data Service: Helps you to access, sort, catch, and synchronize data
User Interface: Links the base lightning components and the lightning data service to capitalize on the same

The LWC framework has no dependencies on the parent platform. The Salesforce binding, as discussed earlier, is simply built upon the framework. This layered structure helps you to use your LWC framework to create web applications that run anywhere. In the past, this feature did not exist and developers had to build different frameworks for different components of an application, therefore limiting the language requirements and delivering the guarantee of a competitive framework.

Some of the advantages of the framework include compliance with the latest web standards, space and storage optimization, increased speed of processing, and the fact that it’s easy to learn, adapt, and pass on the knowledge.

What Makes LWC a Game-changer Today?

A lot has changed with Salesforce Lightening over the past few years. In July 2019, many releases were shipped by Salesforce for their developer tools:

  • Visual Studio Code: The web development editor available with LWC offers a rich set of add-ons such as code completion, refraction, and overall easier writing experience of common coding languages like HTML, JavaScript, and CSS. The user community also keeps adding extensions to the platform, which helps tailor the output as per your requirement. Salesforce also adds a host of extensions specifically for the LWC platform on Salesforce to assist you.
  • Code Completions: Online documentation and full code completion are seen for HTML and JavaScript codes for elements, values, and attributes on LWC components like static resources and custom labels. This takes place with the help of templates that exist in the LWC framework, which automatically run the code completions.
  • ESLint Integration: ESLint is a static code analysis tool that helps in identifying anomalies in a JavaScript code. Warnings are delivered in the case of errors, which helps ensure consistency and efficiency.
  • Lightning Explorer: It allows you to browse through all the components and their properties in your platform, and it also provides easy access to templates, modules, and documentation.
  • LWC in Aura Apps & Visualforce: You can now combine features built using both LWC and Visualforce to create a page consisting of both functionalities. Similarly, LWC components are now supported in Aura Apps.
  • Extended Email Configuration: Outlook and Gmail panes are integrated with LWC using a ‘lightning inbox’ for seamless sharing/storage.
  • Multi-Device Configuration: While using LWC on the main page, you can declare from your component supports: desktop, phone, or both.

These updates bring together the cutting-edge programming model based on the latest web standards in combination with Salesforce metadata. This combination can be used to optimize performance and productivity in one’s efforts towards the development of a web application. Code completion, anomaly detection, browser ecosystem, and numerous add-ons via the visual code studio are some of these latest updates.
