Svelte Components

 

 

Introduction to Svelte Components

  • The svelte components are similar to the “react” or “vue” framework component to create a web application.
  • The svelte components are reusable parts of the code to combine HTML, CSS, and JavaScript code.
  • The svelte component is self-contained code using summarize basic web technologies like HTML, JavaScript, and CSS.
  • The svelte component is a JavaScript framework to create fast applications and part of the interactive interfaces.
  • The svelte component is similar to the other web application component and it works on the “svelte” extension file.
  • The svelte component divided web applications into small parts to make an easy and sorted application.
  • The svelte component creates small user interfaces to remove the complexity of the web application using the svelte framework.
  • The svelte framework is component-based architecture and different components use for fast, sorted, and user-friendly applications.

Svelte Components

  • The svelte framework is based on the component. This framework uses the different components to create small user interfaces.
  • The different component creates header, footer, side navigation bar, and main content of the application.
  • The component is placed in a script tag, main tag, and style tag in the svelte file.
  • The root component is the main component of the svelte framework. This component creates by file with the “svelte” extension.

Root component

Example: Application.svelte

The root component divides into three parts of the interfaces.

  • Header component
  • Footer component
  • Content component

The content component divides into two parts.

  1. Modal component
  2. Sidebar component

Root component

  • The root component stores all components in one file.
  • This component categorizes with different interfaces.
  • The root component creates using HTML, CSS, and JavaScript tags.
  • Example: Application.svelte

Header component

  • The header component creates the header of the web application.
  • The header component is used for the top side of the application.
  • You can add multiple tabs and buttons in the header component.
  • Example: Headers. svelte

Footer component

  • The footer component creates the footer of the web application.
  • The header component is used for the bottom side of the application.
  • You can add multiple tabs and buttons in the footer component.
  • You can add content and the required links to the application.
  • Example: Footers. svelte

Content component

  • The content component creates the core part of the web application.
  • The content component is used for the middle part or center part of the application.
  • You can add multiple tabs and buttons in the content component.
  • You can add content and the required links to the application.
  • The other advanced function and tools are used to connect with the user.
  • This component creates model and sidebar components at the middle part of the application.
  • Example: Contents.svelte

Modal component

  • The modal component is part of the content component.
  • This component is used for the center part of the web application.
  • The modal component creates components and stores other tools or components.
  • You can add multiple tabs and buttons in the content component.
  • You can add content and the required links to the application.
  • The other advanced function and tools are used to connect with the user.
  • Example: Modals.svelte

sidebar component

  • The root component stores sidebar components in one file.
  • The sidebar component is part of the content component.
  • This component is used for the left or right part of the web application.
  • The modal component creates components and stores other tools or components.
  • You can add multiple tabs and buttons in the content component.
  • You can add content and the required links to the application.
  • The other advanced function and tools are used to connect with the user.
  • Example: Sidebar.svelte

Basic about Root (App) components

  • The root component stores above all components in one file.
  • This component is used in the core file or used another file and imports it.
  • The root (App) component file mainly contains three web technology tags.
  • The JavaScript technology is representing or using <script> tag.
  • The HTML technology is representing or using markup tags such as a <P>, <div> and etc.
  • The CSS technology is representing or using <style> tag.
  • The svelte file uses tags in order to JavaScript, HTML, and CSS.
<script> write JavaScript code here… </script>
<div> write HTML code here… </div>
<style> write CSS code or style here… </style>

Example:

<script> let topic = "svelte" </script>
<div> learn {topic}. </div>
<style> div{color : blue; } </style>

Output:

svelte components 1

  • The JavaScript creates variables with the topic name.
  • The HTML creates the “div” component.
  • This component contains text with a JavaScript variable.
  • The CSS style contains a markup tag component which “div” component.

Nested component components

  • The root component stores all components in one file.
  • The svelte creates another component file.
  • This file connects with the root component file with the import tag in the script.
  • You can create multiple component files like header, footer, content file.
  • The above files must connect with the root/App component file.
<script>
import file_name from './path/file_name.svelte';
</script>

Root component

  • The root component stores all components in one file.
  • This component categorizes with different interfaces.
  • The root component creates using HTML, CSS, and JavaScript tags.
  • Example: Application. svelte

Modal component

  • The component is used for the center part of the web application.
  • The modal component creates components and stores other tools or components.
  • Example: Modals.svelte

Example:
File name: Application.svelte

<script>
import Modals from './Modals.svelte';
let topic = "svelte"
</script>
<Modals/>
<div> learn {topic}. </div>
<style> div{color : blue; } </style>
File name: Modals.svelte

svelte components 2

  • The javascript uses the “import” function for a nested component.
  • Another component connects with the root component.
  • The JavaScript creates variables with the topic name.
  • The HTML creates the “div” component.
  • This component contains text with a JavaScript variable.
  • The CSS style contains a markup tag component which “div” component.

Conclusion

  • The svelte components create multiple interfaces and connect with one link.
  • This component uses to create a user-friendly, attractive, and easy web application.
  • The svelte component helps to reduce coding complexity and load.
