Svelte 5 SvelteKit 2 .cursorrules prompt file

I'm using svelte 5 instead of svelte 4 here is an overview of the changes.

Overview

Svelte 5 introduces runes, a set of advanced primitives for controlling reactivity. The runes replace certain non-runes features and provide more explicit control over state and effects.

$state

Purpose: Declare reactive state.
Usage:

`<script>`let count = $state(0);`</script>`

Replaces: Top-level let declarations in non-runes mode.
Class Fields:

class Todo {	done = $state(false);	text = $state();	constructor(text) {		this.text = text;	}}

Deep Reactivity: Only plain objects and arrays become deeply reactive.

$state.raw

Purpose: Declare state that cannot be mutated, only reassigned.
Usage:

`<script>`let numbers = $state.raw([1, 2, 3]);`</script>`

Performance: Improves with large arrays and objects.

$state.snapshot

Purpose: Take a static snapshot of $state.
Usage:

`<script>`	let counter = $state({ count: 0 });	function onClick() {		console.log($state.snapshot(counter));	}`</script>`

$derived

Purpose: Declare derived state.
Usage:

`<script>`let count = $state(0); let doubled = $derived(count * 2);`</script>`

Replaces: Reactive variables computed using $: in non-runes mode.

$derived.by

Purpose: Create complex derivations with a function.
Usage:

`<script>`	let numbers = $state([1, 2, 3]); let total = $derived.by(() => numbers.reduce((a, b) => a + b,	0));`</script>`

$effect

Purpose: Run side-effects when values change.
Usage:

`<script>`	let size = $state(50);	let color = $state('#ff3e00');	$effect(() => {		const context = canvas.getContext('2d');		context.clearRect(0, 0, canvas.width, canvas.height);		context.fillStyle = color;		context.fillRect(0, 0, size, size);	});`</script>`

Replacements: $effect replaces a substantial part of $: {} blocks triggering side-effects.

$effect.pre

Purpose: Run code before the DOM updates.
Usage:

`<script>`	$effect.pre(() =>{' '}	{		// logic here	}	);`</script>`

Replaces: beforeUpdate.

$effect.tracking

Purpose: Check if code is running inside a tracking context.
Usage:

`<script>`console.log('tracking:', $effect.tracking());`</script>`

$props

Purpose: Declare component props.
Usage:

`<script>`let {(prop1, prop2)} = $props();`</script>`

Replaces: export let syntax for declaring props.

$bindable

Purpose: Declare bindable props.
Usage:

`<script>`let {(bindableProp = $bindable('fallback'))} = $props();`</script>`

$inspect

Purpose: Equivalent to console.log but re-runs when its argument changes.
Usage:

`<script>`let count = $state(0); $inspect(count);`</script>`

$host

Purpose: Retrieve the this reference of the custom element.
Usage:

`<script>`	function greet(greeting) {		$host().dispatchEvent(new CustomEvent('greeting', { detail: greeting }));	}`</script>`

Note: Only available inside custom element components on the client-side.

Overview of snippets in svelte 5

Snippets, along with render tags, help create reusable chunks of markup inside your components, reducing duplication and enhancing maintainability.

Snippets Usage

Definition: Use the #snippet syntax to define reusable markup sections.
Basic Example:

{#snippet figure(image)}	`<figure>`		`<img src={image.src} alt={image.caption} width={image.width} height={image.height} />`		`<figcaption>`{image.caption}`</figcaption>`	`</figure>`{/snippet}

Invocation: Render predefined snippets with @render:

{@render figure(image)}

Destructuring Parameters: Parameters can be destructured for concise usage:

{#snippet figure({ src, caption, width, height })}	`<figure>`		`<img alt={caption} {src} {width} {height} />`		`<figcaption>`{caption}`</figcaption>`	`</figure>`{/snippet}

Snippet Scope

Scope Rules: Snippets have lexical scoping rules; they are visible to everything in the same lexical scope:

`<div>`	{#snippet x()}		{#snippet y()}...{/snippet}		`<!-- valid usage -->`		{@render y()}	{/snippet}	`<!-- invalid usage -->`	{@render y()}`</div>``<!-- invalid usage -->`{@render x()}

Recursive References: Snippets can self-reference or reference other snippets:

{#snippet blastoff()}	`<span>`🚀`</span>`{/snippet}{#snippet countdown(n)}	{#if n > 0}		`<span>`{n}...`</span>`		{@render countdown(n - 1)}	{:else}		{@render blastoff()}	{/if}{/snippet}{@render countdown(10)}

Passing Snippets to Components

Direct Passing as Props:

`<script>`	import Table from './Table.svelte';	const fruits = [{ name: 'apples', qty: 5, price: 2 }, ...];`</script>`{#snippet header()}	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`{/snippet}{#snippet row(fruit)}	`<td>`{fruit.name}`</td>`	`<td>`{fruit.qty}`</td>`	`<td>`{fruit.price}`</td>`	`<td>`{fruit.qty * fruit.price}`</td>`{/snippet}`<Table data={fruits} {header} {row} />`

Implicit Binding:

`<table data="{fruits}">`	{#snippet header()}	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`	{/snippet} {#snippet row(fruit)}	`<td>`{fruit.name}`</td>`	`<td>`{fruit.qty}`</td>`	`<td>`{fruit.price}`</td>`	`<td>`{fruit.qty * fruit.price}`</td>`	{/snippet}`</table>`

Children Snippet: Non-snippet content defaults to the children snippet:

`<table data="{fruits}">`	`<th>`fruit`</th>`	`<th>`qty`</th>`	`<th>`price`</th>`	`<th>`total`</th>`	`<!-- additional content -->``</table>``<script>`	let { data, children, row } = $props();`</script>``<table>`	`<thead>`		`<tr>`			{@render children()}		`</tr>`	`</thead>`	`<!-- table body -->``</table>`

Avoid Conflicts: Do not use a prop named children if also providing content inside the component.

Typing Snippets

TypeScript Integration:

`<script lang="ts">`	import type { Snippet } from 'svelte';	let { data, children, row }: {		data: any[];		children: Snippet;		row: Snippet`<[any]>`;	} = $props();`</script>`

Generics for Improved Typing:

`<script lang="ts" generics="T">`	import type { Snippet } from 'svelte';	let { data, children, row }: {		data: T[];		children: Snippet;		row: Snippet`<[T]>`;	} = $props();`</script>`

Creating Snippets Programmatically

Advanced Use: Create snippets programmatically using createRawSnippet where necessary.

Snippets and Slots

Mixing with Slots: Slots are deprecated but still work. Snippets provide more flexibility and power.
Custom Elements: Continue using <slot /> for custom elements as usual.

Sure! Here are the succinct instructions for handling Event Handlers in Svelte 5, tailored for the AI-integrated code editor to help it understand and utilize these features effectively.

Custom Instructions for Svelte 5 Event Handlers in Cursor AI

Overview

In Svelte 5, event handlers are treated as properties, simplifying their use and integrating them more closely with the rest of the properties in the component.

Basic Event Handlers

Declaration: Use properties to attach event handlers.

`<script>`	let count = $state(0);`</script>``<button onclick={() =>` count++}>	clicks: {count}`</button>`

Shorthand Syntax:

`<script>`	let count = $state(0);	function handleClick() {		count++;	}`</script>``<button {handleClick}>`	clicks: {count}`</button>`

Deprecation: The traditional on: directive is deprecated.

Component Events

Replacing createEventDispatcher: Components should accept callback props instead of using createEventDispatcher.

`<script>`	import Pump from './Pump.svelte';	let size = $state(15);	let burst = $state(false);	function reset() {		size = 15;		burst = false;	}`</script>``<Pump	inflate={(power) =>` { size += power; if (size > 75) burst = true; }}	deflate={(power) => { if (size > 0) size -= power; }}/>{#if burst}	`<button onclick={reset}>`new balloon`</button>`	`<span class="boom">`💥`</span>`{:else}	`<span class="balloon" style="scale: {0.01 * size}">` 🎈 `</span>`{/if}

Bubbling Events

Accept Callback Props:

`<script>`	let { onclick, children } = $props();`</script>``<button {onclick}>`	{@render children()}`</button>`

Spreading Props:

`<script>`	let { children, ...props } = $props();`</script>``<button {...props}>`	{@render children()}`</button>`

Event Modifiers

Avoiding Modifiers: Modifiers like |once, |preventDefault, etc., are not supported. Use wrapper functions instead.
Example Wrapper Functions:

`<script>`	function once(fn) {		return function (event) {			if (fn) fn.call(this, event);			fn = null;		};	}	function preventDefault(fn) {		return function (event) {			event.preventDefault();			fn.call(this, event);		};	}`</script>``<button onclick={once(preventDefault(handler))}>`...`</button>`

Special Modifiers: For capture:

`<button onclickcapture={...}>`...`</button>`

Multiple Event Handlers

Combining Handlers: Instead of using multiple handlers, combine them into one.

`<button	onclick={(e) =>` {		handlerOne(e);		handlerTwo(e);	}}>	...`</button>`

<script>
let { children } = $props();
</script>
<button>{@render children("some value")}</button>
```

I'm also using sveltekit 2 which also has some changes I'd like you to keep in mind

Redirect and Error Handling

In SvelteKit 2, it is no longer necessary to throw the results of error(...) and redirect(...). Simply calling them is sufficient.

SvelteKit 1:

import { error } from '@sveltejs/kit';function load() {	throw error(500, 'something went wrong');}

SvelteKit 2:

import { error } from '@sveltejs/kit';function load() {	error(500, 'something went wrong');}

Distinguish Errors:
Use isHttpError and isRedirect to differentiate known errors from unexpected ones.

import { isHttpError, isRedirect } from '@sveltejs/kit';try {	// some code} catch (err) {	if (isHttpError(err) || isRedirect(err)) {		// handle error	}}

Cookies now require a specified path when set, deleted, or serialized.

SvelteKit 1:

export function load({ cookies }) {	cookies.set(name, value);	return { response };}

SvelteKit 2:

export function load({ cookies }) {	cookies.set(name, value, { path: '/' });	return { response };}

Top-Level Promise Handling

Promises in load functions are no longer awaited automatically.

Single Promise:

SvelteKit 1:

export function load({ fetch }) {    return {        response: fetch(...).then(r => r.json())    };}

SvelteKit 2:

export async function load({ fetch }) {    const response = await fetch(...).then(r => r.json());    return { response };}

Multiple Promises:

SvelteKit 1:

export function load({ fetch }) {    return {        a: fetch(...).then(r => r.json()),        b: fetch(...).then(r => r.json())    };}

SvelteKit 2:

export async function load({ fetch }) {    const [a, b] = await Promise.all([        fetch(...).then(r => r.json()),        fetch(...).then(r => r.json())    ]);    return { a, b };}

`goto` Changes

goto(...) no longer accepts external URLs. Use window.location.href = url for external navigation.

Relative Paths Default

Paths are now relative by default, ensuring portability across different environments. The paths.relative config option manages this behavior.

Deprecated Settings and Functions

Server Fetches are no longer trackable.
preloadCode Arguments: Must be prefixed with the base path.
resolvePath Replacement: Use resolveRoute instead.

import { resolveRoute } from '$app/paths';const path = resolveRoute('/blog/[slug]', { slug: 'hello' });

Improved Error Handling

Errors trigger the handleError hook with status and message properties for better discernment.

Dynamic Environment Variables

Dynamic environment variables cannot be used during prerendering. Use static modules instead.

`use:enhance` Callback Changes

The properties form and data have been removed from use:enhance callbacks, replaced by formElement and formData.

Forms with File Inputs

Forms containing <input type="file"> must use enctype="multipart/form-data".

With these adjusted guidelines, your AI can now generate SvelteKit 2 code accurately while considering the migration changes.

If you need more information or specific requirements to enhance your response, please ask the user for additional details.

Java Development Guide: Modern Design Pattern Principles

Objective:

Develop a Java framework that demonstrates the implementation of both traditional and modern design patterns, integrating advanced Java features to build scalable, maintainable, and modern applications suitable for cloud-native environments.

Guidelines:

Select and Implement 10 Design Patterns:

Include a mix from the following categories:
- Creational Patterns:
- Singleton, Factory Method, Abstract Factory, Builder, Prototype
- Structural Patterns:
- Adapter, Bridge, Composite, Decorator, Facade, Proxy
- Behavioral Patterns:
- Observer, Strategy, Command, Iterator, State, Memento, Chain of Responsibility
- Modern Patterns:
- Dependency Injection (DI), Repository Pattern, Event Sourcing, Command Query Responsibility Segregation (CQRS), Circuit Breaker
For each pattern:
- Provide a clear explanation of why it was chosen.
- Discuss its relevance in modern Java applications, such as microservices, reactive systems, or cloud-native environments.
- Include code examples demonstrating the pattern in action.

Integration with Modern Java Frameworks:

Spring Framework:
- Dependency Injection (DI): Demonstrate how Spring facilitates DI to promote loose coupling. Provide examples of constructor and setter injection in real-world scenarios.
- Factory Patterns: Explain how Spring's BeanFactory and ApplicationContext use Factory Method and Abstract Factory patterns to manage bean creation and lifecycle.
- Aspect-Oriented Programming (AOP): Illustrate how patterns like Proxy and Decorator are utilized in Spring AOP to implement cross-cutting concerns such as logging, security, and transaction management.

Reactive Programming and Patterns:

Project Reactor and RxJava:
- Observer Pattern: Showcase how reactive libraries employ the Observer pattern for asynchronous and non-blocking event handling.
- Functional Interfaces and Lambdas: Emphasize the use of functional programming concepts to implement patterns like Strategy and Command in a reactive context.
- Backpressure Management: Discuss how reactive streams handle backpressure to prevent resource exhaustion in systems with variable data flow rates.

Cloud-Native Development Considerations:

Stateless Design:
- Highlight the importance of designing stateless services in microservices architecture for scalability and resilience. Show how patterns like Strategy and Command support stateless operations.
Distributed Systems Management:
- Event Sourcing and CQRS: Explain how these patterns help maintain data consistency and scalability across distributed systems by separating read and write operations and capturing all changes as events.
- Circuit Breaker Pattern: Introduce the Circuit Breaker pattern to manage fault tolerance, enabling services to fail gracefully in distributed architectures.

Advanced Use of Generics and Functional Interfaces:

Implement patterns using generics to ensure type safety and reusability.
Leverage functional interfaces and lambda expressions to simplify implementations, particularly in patterns like Strategy, Command, and Observer.

Optimized Use of Java Collections and Stream API:

Utilize the Java Collections Framework effectively, demonstrating advanced techniques like custom comparators or thread-safe collections.
Modernize patterns like Iterator using the Stream API for internal iteration, parallel processing, and improved performance.

Interface and Abstract Class Driven Development:

Use interfaces with default and static methods to provide flexible and extensible designs.
Employ abstract classes where shared functionality or common state is required, as seen in patterns like Template Method or Bridge.

Modular, Readable, and SOLID Code Structure:

Structure the codebase using Java modules (Java Platform Module System) for better encapsulation and maintainability.
Ensure adherence to SOLID principles:
- Single Responsibility Principle: Each class should have one reason to change.
- Open/Closed Principle: Classes should be open for extension but closed for modification.
- Liskov Substitution Principle: Subtypes must be substitutable for their base types.
- Interface Segregation Principle: Prefer specific interfaces over general-purpose ones.
- Dependency Inversion Principle: Depend upon abstractions, not concretions.

Enhanced Java Documentation with Modern Insights:

Write comprehensive JavaDoc comments that explain not just the "how," but also the "why" behind design decisions.
Include insights on modern practices, such as the benefits of immutability, the use of streams over traditional loops, and the application of functional programming concepts.

Error Handling, Concurrency, and Robustness:
- Advanced Error Handling:
- Implement robust error handling using custom exceptions and exception hierarchies.
- Use try-with-resources for effective management of resources like I/O streams.
- Concurrency Utilities:
- Address concurrency concerns using Java's concurrency utilities such as CompletableFuture, ExecutorService, and atomic variables.
- Utilize concurrent collections like ConcurrentHashMap to manage shared data safely.
- Asynchronous Programming:
- Demonstrate the use of asynchronous operations to enhance application responsiveness and scalability.
Educational Focus and Best Practices:
- Code Readability:
- Emphasize clean code principles, meaningful variable names, consistent formatting, and modular code structure.
- Testing and Debugging:
- Encourage the use of unit testing frameworks like JUnit 5 and mocking libraries like Mockito.
- Highlight the importance of test-driven development (TDD).
- Documentation:
- Stress the value of thorough documentation using JavaDoc for maintainability and team collaboration.
Example Implementation:
```java
/**
- Demonstrates the Strategy pattern using functional interfaces and lambda expressions.
- This modern approach simplifies the implementation and enhances flexibility.
- @param <T> The type of data being processed.
  */
  @FunctionalInterface
  public interface ProcessingStrategy<T> {
  void process(T data);
  }
public class DataProcessor<T> {
private ProcessingStrategy<T> strategy;
```
 public DataProcessor(ProcessingStrategy`<T>` strategy) {     this.strategy = strategy; } public void executeStrategy(T data) {     strategy.process(data); } public static void main(String[] args) {     // Using a lambda expression for the strategy     DataProcessor`<String>` processor = new DataProcessor<>(data -> System.out.println(data.toUpperCase()));     processor.executeStrategy("hello world");     // Changing the strategy at runtime     processor = new DataProcessor<>(data -> System.out.println(new StringBuilder(data).reverse()));     processor.executeStrategy("hello world"); }
```
}
```
Explanation:
- Functional Interface: ProcessingStrategy is a functional interface, allowing the use of lambda expressions.
- Lambda Expressions: Simplify the creation of strategy instances without the need for concrete classes.
- Flexibility: Strategies can be changed at runtime, promoting the Open/Closed Principle.
