How do I set up environment and create first app?

# Step 1: Environment Setup Install prerequisites: - Download and install [Node.js](https://nodejs.org/) (version 20+ recommended). - Install [VS Code](https://code.visualstudio.com/) and the [Svelte extension](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode). Create your first project: ```bash npx sv create my-svelte-app cd my-svelte-app npm install npm run dev ``` Open http://localhost:5173 to see the app. Edit `src/routes/+page.svelte` to experiment.

How do I learn core concepts via interactive tutorial?

# Step 2: Interactive Tutorial Basics Visit the [official Svelte tutorial](https://svelte.dev/tutorial). Complete **Basic Svelte** sections: - Reactivity: Use `$: count = 1` for reactive declarations. - Props: Pass data with ` `. - Bindings: `bind:value={name}`. - Classes and styles: `class:foo={true}`. Work through exercises in-browser or locally. Use 'solve' if stuck.

How do I master data flow: props, events, bindings?

# Step 3: Data Flow Mastery Continue tutorial **Advanced Svelte**: - Props: Export values `export let name;`. - Events: `on:click={handleClick}` or `dispatch('message')`. - Bindings: Two-way like `bind:this={element}`. **Example component:** ```svelte let count = 0; function increment() { count += 1; } {count} ``` Build a todo list passing props between components.

How do I handle state with stores and transitions?

# Step 4: State and Animations From tutorial: - **Stores**: `import { writable } from 'svelte/store'; const count = writable(0);` Use `$count` in markup. - **Transitions**: `transition:fade`, `in:slide`. **Stores example:** ```svelte import { writable } from 'svelte/store'; export const todos = writable([]); {#each $todos as todo} {todo.text} {/each} ``` Add transitions to your todo app. Explore Context API for deeper sharing.

How do I build full app and deploy with sveltekit?

# Step 5: SvelteKit App and Deploy Shift to [SvelteKit docs](https://kit.svelte.dev/docs). - **Routing**: Files in `src/routes/` become pages (+page.svelte). - **Data loading**: `+page.js` export load function. - **Deploy**: `npm run build`, deploy to Vercel/Netlify. Extend your todo app: ```bash # In existing app npm run build # Preview: npm run preview ``` Follow [deploy guide](https://kit.svelte.dev/docs/deployment). Push to GitHub, connect to Vercel.
