Svelte Tutorial – How to Create a ListView Using Items As a Data Source

The Svelte tutorial is a free JavaScript framework for building responsive web applications. It’s an excellent choice for those looking for a fast, lightweight, and scalable framework. Compared to React, Svelte is much faster. In this Svelte tutorial, you’ll learn how to create a list view using items as its data source.

ListView in Svelte uses the items property as its data source

The ListView component in Svelte uses the items property as the data source. ListView in Svelte can display an infinite list of items or a finite list of items. The item’s property can be specified as an observable array. In this example, we are going to create an infinite list component that renders a list of titles as the items in the list.

ListView in Svelte uses the items data source to create a scrollable list of items. Items are added to the view from the items property of an array or from a database. The list is then populated by calling the setAdaptor() method. This method will associate an adapter with each item.

Testing in Svelte

The Svelte library includes many UI components that can be used for testing purposes. These components are designed to separate view logic from business logic. This means that data transformation and cross-component state management should be kept outside the Svelte component. You should also keep JavaScript functionality outside of the Svelte component. While the Svelte library has its own tests, you should not use them to test the underlying implementation of JavaScript in your app.

While Svelte doesn’t recommend a particular testing tool or strategy, the more widely-used frameworks like React and Vue offer their own recommended tools. For example, React and Vue recommends using Jest and Mocha for testing their applications. Similarly, JavaScript testing libraries can be used for Svelte. However, you should note that integrating these tools can be difficult.
