To get the current component tag name in Svelte, you can use the $$ syntax. You can access the component's tag name within the script block or the HTML code.
In the script block, you can use the $$ prefix followed by component. For example, $$component provides access to the current component instance. To get the component's tag name, you can use $$component.nodeName.
In the HTML code, you can use the local special variable and access its nodeName property. For example, <svelte:options tag={local.nodeName} /> will set the current component's tag name to the tag option.
Both of these methods allow you to retrieve the component's tag name dynamically and use it for various purposes within your Svelte application.
How can I obtain the tag name of the Svelte component being rendered?
You can obtain the tag name of the Svelte component being rendered by accessing the $$ property of the component instance.
import { onMount } from 'svelte';
onMount(() => { console.log($$.ctx.component._.$$); });
The $$ property contains various properties related to the component instance. The ctx property refers to the component's context, and the component property refers to the component itself. We can access the _.$$ property of the component to obtain metadata about the component, including the tag name.
Note that this approach relies on internal Svelte properties and may not be officially documented or supported.
How do I get the tag name of the component I'm currently inside in Svelte?
In Svelte, you can get the tag name of the component you are currently inside using the $ symbol followed by the component name.
Here's how you can retrieve the tag name:
In this example, the component is named foo, so $.foo will give you the tag name of the component as a string.
Keep in mind that this approach only works inside a component, and not in the top-level app file. It gives you the tag name of the specific instance of the component, not the component itself.
What is the recommended function to use for retrieving the tag name of the current Svelte component?
In Svelte, you can retrieve the tag name of the current component by using the $$ syntax. The $$ prefix is used to access internal properties or methods.
Here's an example of how you can retrieve the tag name of the current Svelte component:
console.log($$.constructor.name);
In this example, $$ is used to access the internal constructor property, and then name is used to retrieve the tag name of the current component.
Note that the $$ syntax is an internal convention and may change in future versions of Svelte.
What is the simplest approach to retrieve the tag name of the current Svelte component?
The simplest approach to retrieve the tag name of the current Svelte component is by using the name property of the component's definition.
Here's an example:
This example exports a name variable from the component's script tag. In the component's markup, the tag name is displayed using curly braces and the name variable.
To use this component, you can provide the tag name explicitly:
Alternatively, you can use the component variable in other Svelte components to retrieve the current tag name:
In this example, the component variable is imported from the svelte/internal module. The name property of component provides the tag name of the enclosing Svelte component.
