Create new Svelte components by extending existing ones

Github

Overview

Svelte-extend offers a unique approach to component creation in the Svelte framework by allowing developers to extend existing components rather than starting from scratch. This library addresses the need for more flexibility when building Svelte applications, particularly for those who find traditional OOP inheritance lacking in this context. By utilizing the extend HTML tag, developers can create new components that inherit functionalities from base components while still allowing for customization.

While the author of Svelte may have valid reasons for the original design choices, Svelte-extend can be particularly useful in specific scenarios where enhanced reusability and customization are critical. Users should consider their requirements carefully before integrating this library into their workflow.

Features

  • Easily Extend Components: Utilize the extend tag in your .svelte files to create new components that leverage existing ones, simplifying the development process.

  • Customizable HTML Structure: Add the html attribute to control the order of HTML insertion from base and extended components, providing flexibility in rendering.

  • Overwriting Scripts: Start fresh by specifying a new script tag in the extended component, which completely replaces the base component’s script if desired.

  • Variable Management: The extend attribute allows for merging base and extended script contents smoothly, letting you define or modify variables as needed.

  • Style Management: Override base styles effortlessly by creating a style tag in your extended component, with options to control the style order using the extend attribute.

  • Simplified Integration: The straightforward syntax ensures a smooth incorporation process, making it easier for developers to adapt and adopt the library into their existing projects.

  • Preservation of Base Functionality: Even while extending, the core functionalities of the base component are preserved, ensuring reliability and foundational integrity in your applications.
