Tips & Tricks To Help You Get Started With Salesforce Lightning Web Development

Aura components are now outdated, and LWC is more lightweight and is faster than its predecessor. It means that you can implement lesser loading times upon your developed products. LWC comes with a higher responsive UI than Aura and can execute faster executions. Its idea is to pick up right from the spot where Lightning Experience or LEX drags.

The Salesforce Lightning Web Development concept upon the lightning components is built with ECMAScript. Hence, it allows extended classes, arrow functions, imports, etc. With LWC in existence, one doesn’t need to define the component attributes anymore. You can just mark any property with the use of an API decorator.

Moreover, the idea of using Salesforce lightning web development allows events to be dispatched without the necessity of creating any specific definition for it. Following that, LWC eliminates the need to wrap call-backs and import any script from a different LWC.

Salesforce DX is accountable as a modern development experience by Salesforce. It offers the developers an agile development lifecycle. It is loaded with superior codes and is primarily preferable by professional programmers for building web pages & applications and proficiently managing them.

The purpose of Salesforce DX is to combine the functionality of Heroku and Force.com development solutions under Salesforce. It is to trigger modern improvements for triggering source-driven development and automated testing outcomes.

As it puts up low reliance upon code programming aspects for developing functionalities, the pace of website design increases. Hence, it also reduces the technical expenses upon building a website. But if you intend to use Salesforce DX to build a high-performance site, you might need deep insight into JavaScript and HTML utilization.

With the use of Salesforce Lightning Web Development concepts, you can learn to create your first Salesforce DX project. When you take up the course of study from available online resources, take note of the ideas and steps upon creating your first Salesforce DX project. You can also get help with CLI for creating the same. You will learn about it more further in this guide.

Salesforce Lightning services with LWC development is a forward concept of today. But there are still places where this concept is not yet supported! For instance, the Salesforce Console APIs such as Workspace, Utility bar, Navigation item, and the URL addressing tabs do not support LWC.

But, even with the limitations, you can seek to work around them by adapting nesting applications. In this idea, LWC will be nested within an Aura component. And then, you can seek to handle the communication between the parent (Aura) and child (LWC) component. It is done by firing off a specific event to the parent component and calling a method or setting an attribute exposed by the child component.

It is important to consider that you can nest LWC in the Aura component, but vice versa is impossible! LWC doesn’t provide two-way data binding efficiencies. Hence, the user input doesn’t propagate to the controller automatically. The API properties passed from a parent cannot be modified within the child component. To eradicate this limitation, you will have to expose the parent API property through a setter/getter, which will clone its value to a specific internal property.

LWC doesn’t support the ‘Merge Field’ expressions, which can be handled by enabling a getter property onto the component controller. And finally, the component styling aspects are not liable for reaching across the component boundaries or turning around to become a standard component. The exception for this case is to override all of the CSS variables that pass onto the child or Aura component boundary.

After you get exposure to the brief capabilities of Salesforce LWC, you must thrive on gaining theoretical and practical knowledge of the concept. And taking up a beginner’s or basic course is the right way to acquire it. You can talk to a Salesforce Lightning consultant to get a clear insight into what course would help you.

The consultant will analyze your current knowledge upon LWC and help you decide if you need the beginner’s course or can move onto the intermediate level directly. If you are completely new to the concept, it is better to understand it from basics to expert level!

Every course you take will have different modules and projects to work on. You do not have to rush upon the modules and project completions, as you will have ample time to get over it. The course’s purpose is to learn web development prospects from Salesforce LWC. After taking the course, you will be ready to start with your practical implementations.

After you have mastered the course and have the basic idea of the concept, the Salesforce lightning consultant will recommend you install the Extended Suspension Pack. Most advisors will suggest you get the extension for Visual Studio Code, which is not the best alternative.

You can install the pack by clicking upon the extension’s icon over the left-side toolbar of the Visual Studio Code. And then, you can select the Extension Pack of Salesforce. This extension pack will consist of 4 different JavaScript libraries, ESLint, Apex PMD, XML, and Prettier. You will need these libraries on priority while executing Salesforce lightning web development.
