When responding to questions, follow the Chain of Thought method. First, outline a detailed pseudocode plan step by step, then confirm it, and proceed to write the code.Remember the following important mindset when providing code:SimplicityReadabilityPerformanceMaintainabilityTestabilityReusabilityAdhere to the following guidelines in your code:Utilize early returns for code readability.Use Tailwind classes for styling HTML elements instead of CSS or <style> tags.Prefer "class:" instead of the tertiary operator in class tags when possible.Employ descriptive variable and function/const names, and prefix event functions with "handle," such as "handleClick" for onClick and "handleKeyDown" for onKeyDown.Implement accessibility features on elements, including tabindex="0", aria-label, on:click, on:keydown, and similar attributes for tags like <button>.Use consts instead of functions, and define a type if possible.Your responses should focus on providing correct, best practice, DRY principle (Don't Repeat Yourself), bug-free, fully functional, and working code aligned with the listed rules above. Prioritize easy and readable code over performance and fully implement all requested functionality. Ensure that the code is complete and thoroughly verified, including all required imports and proper naming of key components. Be prepared to answer questions specifically about Svelte, SvelteKit, JavaScript, TypeScript, TailwindCSS, HTML, and CSS. Your responses should align with the provided coding environment and implementation guidelines.Preferred Syntax and PatternsSvelte ComponentsUse .svelte extension for Svelte componentsUse TypeScript syntax in <script> tags:svelteCopy<script lang="ts">// TypeScript code here</script>State ManagementUse Svelte stores for global state:typescriptCopyimport { writable } from 'svelte/store';export const myStore = writable(initialValue);Access store values in components with the $ prefix:svelteCopy<p>{$myStore}</p>ReactivityUse reactive declarations for derived values:svelteCopy$: derivedValue = someValue * 2;Use reactive statements for side effects:svelteCopy$: { console.log(someValue); updateSomething(someValue);}TypingUse TypeScript for type definitionsCreate interfaces or types for component props:typescriptCopyinterface MyComponentProps { someValue: string; optionalValue?: number;}ImportsUse aliased imports where applicable (as defined in svelte.config.js):typescriptCopyimport SomeComponent from '$lib/components/SomeComponent.svelte';import { someUtil } from '$lib/utils';Async OperationsPrefer async/await syntax over .then() chainsUse onMount for component initialization that requires async operationsStylingUse Tailwind CSS for stylingUtilize Tailwind's utility classes directly in the markupFor complex components, consider using Tailwind's @apply directive in a scoped <style> blockUse dynamic classes with template literals when necessary:svelteCopy<div class={\bg-blue-500 p-4 ${isActive ? 'opacity-100' : 'opacity-50'}`}>`File StructureGroup related components in subdirectories under src/lib/components/Keep pages in src/routes/Use +page.svelte for page components and +layout.svelte for layoutsPlace reusable utility functions in src/lib/utils/Store types and interfaces in src/lib/types/Component DesignFollow the single responsibility principleCreate small, reusable componentsUse props for component configurationUtilize Svelte's slot system for flexible component compositionData FetchingUse SvelteKit's load function for server-side data fetchingImplement proper error handling and loading statesUtilize SvelteKit's form actions for form submissions and mutationsPerformance OptimizationLazy load components and modules when possibleUse Svelte's transition API for smooth UI animationsImplement proper caching strategies for API requestsTestingWrite unit tests for utility functions and complex logicCreate component tests using a testing library compatible with Svelte (e.g., Svelte Testing Library)Implement end-to-end tests for critical user flowsAccessibilityEnsure proper semantic HTML structureUse ARIA attributes when necessaryImplement keyboard navigation for interactive elementsMaintain sufficient color contrast ratiosCode QualityUse ESLint with the recommended Svelte and TypeScript configurationsImplement Prettier for consistent code formattingConduct regular code reviews to maintain code quality and consistencyDocumentationMaintain up-to-date README files for the project and major componentsUse JSDoc comments for functions and complex logicKeep inline comments concise and meaningful
