In order to create and use custom components in a Svelte application, you must first install the Svelte compiler. The Svelte compiler is an open-source JavaScript compiler that enables you to write code in a high-level language and compile it into efficient JavaScript code. To install the Svelte compiler, you can use either the npm package or the GitHub repository. Once installed, you can begin creating your custom components.
Creating a custom component in Svelte is easy and straightforward. To get started, you need to install the Svelte compiler. Once installed, you can create a new component by creating a new file with the .svelte extension. Inside this file, you can write your component code using HTML, CSS, and JavaScript. Once your component is ready, you can import it into your application and use it in your application. To test and debug your component, you can use the Svelte compiler to compile your code and view the output in the browser.
In this step of the tutorial, you will learn how to write your custom component code in Svelte. To begin, you will need to install the Svelte compiler. Once installed, you can create a new component and write your code in it. The code should be written in HTML5 and formatted according to the programming language used. To make it SEO friendly, use tags to link to external websites in the context of the step. Additionally, use tags instead of
tags when writing code and always add
before and after the tag. Format the code lines appropriately, like in an IDE. After writing your component code, you can import it into your application and use it. Finally, test and debug your component to ensure it works as expected.
To import your custom component into your Svelte application, you need to use the import statement. The syntax for this statement is import ComponentName from './ComponentName.svelte'. Replace ComponentName with the name of your component. This statement should be placed at the top of the file where you want to use the component. For example, if you want to use the component in App.svelte, you would add the following line at the top of the file:
import MyComponent from './MyComponent.svelte'Once you have imported your component, you can use it in your application by adding an HTML tag with the same name as your component. For example, if your component is called MyComponent, you can use it in your application like this:
You can also pass data to your component using attributes. For example, if your component has a name property, you can pass a value to it like this:

Now that you have created and imported your custom component into your Svelte application, you can use it in your application. To do this, you need to add the component to the HTML template of your application. You can do this by using the <svelte:component> tag. This tag takes two attributes: this, which is the name of the component, and props, which is an object containing any properties that you want to pass to the component. For example, if you wanted to use the MyComponent component with a name property set to "John", you would write:
<svelte:component this="MyComponent" props="{name: 'John'}" />
Once you have added the component to your HTML template, you can use it in your application. To test that it is working correctly, you can add a debugger statement to the component code and then open the browser's developer tools to see if it is being called correctly.
Once you have written your custom component, you can test and debug it in your Svelte application. To do this, you need to import the component into your application and use it in the code. You can then use the browser's developer tools to inspect the component and check for any errors. To make debugging easier, you can also add console.log() statements to your code to log out any errors or warnings. Additionally, you can use a linter such as ESLint to check for any potential issues with your code. Once you have tested and debugged your component, you can deploy it to production and start using it in your application.
