Tapforce SvelteKit Skill

This skill provides best practices for setting up and developing Svelte projects using SvelteKit ^2.0.0.

When to Use

Use this skill when:

• Setting up a new SvelteKit project
• Developing applications based on SvelteKit framework
• Migrating existing Svelte projects to SvelteKit ^2.0.0
• Configuring SvelteKit project structure and routing

Requirements

• Project based on Node.js ^20.0.0
• Project needs Svelte ^5.0.0
• Project needs SvelteKit ^2.0.0
• Prefer using pnpm ^10.0.0 as default package manager

CLI Commands

sv create

Sets up a new SvelteKit project with options for templates and add-ons.

Usage:

npx sv create [options] [path]

Key Options:

• --template <name>: Project template (minimal, demo, library)
• --types <option>: Type checking (ts, jsdoc)
• --no-types: Skip type checking (not recommended)
• --add [add-ons...]: Add specific add-ons during creation
• --no-add-ons: Skip interactive add-ons prompt
• --install <package-manager>: Specify package manager (npm, pnpm, yarn, bun, deno)
• --no-install: Skip dependency installation
• --from-playground <url>: Create from playground URL

Examples:

# Basic setup with pnpm
pnpm dlx sv create . --install pnpm

# With TypeScript and Tailwind CSS
pnpm dlx sv create . --types ts --add tailwindcss --install pnpm

# From template with add-ons
pnpm dlx sv create . --template demo --add eslint prettier --install pnpm

sv add

Updates existing projects with new functionality and add-ons.

Usage:

npx sv add [add-ons]

Key Options:

• -C, --cwd <path>: Path to project root
• --no-git-check: Skip git dirty files check
• --no-download-check: Skip download confirmations
• --install <package-manager>: Specify package manager
• --no-install: Skip dependency installation

Official Add-ons:

• tailwindcss: Tailwind CSS v4 integration

sv check

Finds errors and warnings in SvelteKit projects.

Usage:

npx sv check [options]

Key Options:

• --workspace <path>: Path to workspace directory
• --output <format>: Output format (human, human-verbose, machine, machine-verbose)
• --watch: Keep process alive and watch for changes

Examples:

# Basic check
pnpm dlx sv check

# Watch mode
pnpm dlx sv check --watch

# With specific output
pnpm dlx sv check --output machine-verbose

# Ignore specific directories
pnpm dlx sv check --ignore "dist,build"

sv migrate

Migrates SvelteKit codebases between versions.

Usage:

npx sv migrate [migration]

Available Migrations:

• svelte-5: Upgrade Svelte 4 to Svelte 5 with runes
• sveltekit-2: Upgrade SvelteKit 1 to SvelteKit 2
• app-state: Migrate $app/stores to $app/state
• self-closing-tags: Update self-closing element syntax
• svelte-4: Upgrade Svelte 3 to Svelte 4
• package: Upgrade @sveltejs/package v1 to v2
• routes: Upgrade pre-release to v1 routing

Examples:

# Interactive migration
pnpm dlx sv migrate

# Specific migration
pnpm dlx sv migrate svelte-5
pnpm dlx sv migrate sveltekit-2

Project Setup

Creating New Project

For new projects, use the SvelteKit CLI command to initialize the backbone codebase. NEVER create core files manually like package.json, tsconfig.json, etc., as SvelteKit CLI will create them for you.

Official documentation: https://svelte.dev/docs/kit/creating-a-project/llms.txt

Quick Setup Commands:

# Basic setup with pnpm (recommended)
pnpm dlx sv create . --install pnpm
pnpm run dev

# With TypeScript and Tailwind CSS
pnpm dlx sv create . --types ts --add tailwindcss --install pnpm
pnpm run dev

# With common development tools
pnpm dlx sv create . --add eslint prettier vitest --install pnpm
pnpm run dev

# Minimal setup with common addons (no-install approach)
pnpm dlx sv create . --template minimal --add tailwindcss prettier adapter-auto --no-install
echo 'packages:
    - .' > pnpm-workspace.yaml
pnpm install
pnpm run dev

# Using npm
npm dlx sv create . --install npm
npm run dev

Troubleshooting pnpm Setup: If you encounter ERR_PNPM_INVALID_WORKSPACE_CONFIGURATION error during installation, see the Package Management rule for solutions.

Template Options:

• minimal: Barebones scaffolding
• demo: Showcase app with word guessing game
• library: Template for Svelte library with svelte-package

Package Manager Support:

• pnpm (recommended)
• npm
• yarn
• bun
• deno

Project Configuration

Update Package JSON

After project creation, update package.json to match project information like name, version, description, etc.

SvelteKit Features

Respect Svelte ^5 and SvelteKit ^2 Features

Ensure all Svelte code (including Svelte and SvelteKit) uses the latest features and coding style from Svelte ^5 and SvelteKit ^2.

Available features from Svelte ^5: $state, $effect, $inspect, etc.

AVOID legacy features from older versions. If you find other skills or rules teaching practices with Svelte/SvelteKit features, learn and follow the latest approaches.
