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

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.
