Component naming conventions in Svelte

Introduction

Good component names help you and others understand what each part does. It makes your code easier to read and maintain.

When creating a new Svelte component to represent a UI part like a button or form.

When organizing components in folders to keep your project tidy.

When sharing components with others or reusing them in different projects.

When debugging or reading code to quickly identify what each component does.

Syntax

Svelte

ComponentName.svelte

Use PascalCase for component file names and component names.

Component names should be descriptive and clear about their purpose.

Examples

A simple button component named with PascalCase.

Svelte

Button.svelte

A component showing user profile details, named clearly to reflect its role.

Svelte

UserProfile.svelte

A navigation bar component, named to describe its function.

Svelte

NavBar.svelte

Sample Program

This is a simple Button.svelte component. The file name uses PascalCase, and the component exports a label prop to customize the button text.

Svelte

<script>
  export let label = "Click me";
</script>

<button>{label}</button>

Important Notes

Always start component names with a capital letter to follow Svelte conventions.

Avoid using spaces or special characters in component names.

Keep names short but meaningful to make your code easier to understand.

Summary

Use PascalCase for all Svelte component names and file names.

Choose clear and descriptive names that explain what the component does.

Consistent naming helps keep your project organized and easy to read.
