Author
September 1, 2022
The Lightning component development model is compatible with the original Aura-based Lightning component development model. HTML and JavaScript are used to create Lightning web components. An Aura component and a Lightning component can coexist and interact with each other on a page. Web components powered by Lightning are custom HTML elements with their own API. In the series below, you will learn how to use Lightning Web Components. This will help you gain a deeper understanding of LWC.
Benefits:
The result of integrating specialized services with a standard web stack is:
- Large-scale modular apps are easy to develop.
- Utilizing the most current web functionalities and constructs.
- Transferable skills and a common model.
- The LWC framework can be quickly ramped up by any web developer working with modern JS frameworks.
- The interoperability of components.
- Enhanced performance
What are the components of a Lightning Web Component (LWC)?

- Has a root tag <template> that defines the HTML for your component.
- Rendering replaces the template with the namespace-component-name tag2. JavaScript

- Use the import statement to import functionality declared in a module, e.g., the core module.
- You can use the export statement to let other code use functionality from a module.
- We extend Lightning Element in the component and export it as a custom wrapper for the standard HTML element.
- @Wire decorators – To read Salesforce data, Lightning web components use a reactive wire service. The component re renders when the wire service provisions data. Components use @wire in their JS class to specify a wire adopter or an Apex method.
- @Api decorators – this decorator is used to make properties or methods public in lightning web components. This way they are accessible outside the component in which they are declared.
- @Track decorators – this decorator is basically used to make properties or methods private in lightning web components. This property is not accessible outside the component in which it is declared. Only accessible within the component itself.

- The Components Label
- Availability
- Attributes of configuration
- Builder Attributes

- Adding style to a component.
- Style sheets are automatically applied.
Conclusion
It’s a great time to learn about Lightning Web Components, which offer the latest web standards, deliver remarkable performance and productivity, and seamlessly integrate with existing code.
Pranshu Goyal, Director of Products at Mirekta, states: “We envision DSM to be used by every small to a medium-sized organization dealing with bad data and want to get rid of duplicates easily with no cost. We have faced issues dealing with duplicates in our organization. That inspired us to make a solution that is not only simple to use but can be used widely to make the organization’s data clean to make them more efficient and productive. We want DSM to be a solution for every organization looking for duplicate management capability better than the Salesforce out-of-the-box solution with no additional cost.”
