This flow shows the steps to create a new Svelte project using create-svelte, install dependencies, and run the app.

Execution Sample

Svelte

npm create svelte@latest my-app
cd my-app
npm install
npm run dev

This sequence creates a new Svelte project folder, installs needed packages, and starts the development server.

Execution Table

Step	Command/Action	System Response	Result
1	npm create svelte@latest my-app	Prompts for template and options	Creates 'my-app' folder with Svelte files
2	cd my-app	Changes directory to project folder	Ready to run commands inside 'my-app'
3	npm install	Downloads and installs dependencies	node_modules folder created with packages
4	npm run dev	Starts development server	Server runs at http://localhost:5173
5	Open browser at localhost:5173	Browser loads app	Svelte starter app visible
6	Exit	Stop server with Ctrl+C	Development session ends

💡 Development server stopped by user; project setup complete

Variable Tracker

Variable	Start	After Step 1	After Step 3	After Step 4	Final
projectFolder	none	my-app created	my-app with dependencies installed	my-app running dev server	my-app ready for development
serverStatus	stopped	stopped	stopped	running	stopped

Key Moments - 3 Insights

Why do we need to run 'npm install' after creating the project?

Because 'npm create svelte@latest' only sets up files, but dependencies like Svelte itself are installed only after 'npm install' (see execution_table step 3).

What happens if you try to run 'npm run dev' before 'npm install'?

The server won't start because required packages are missing. The execution_table shows 'npm install' must run first (step 3) before 'npm run dev' (step 4).

How do you know the development server is running?

The command 'npm run dev' outputs the local URL (http://localhost:5173), and opening it in a browser shows the Svelte app (execution_table step 5).

Visual Quiz - 3 Questions

Look at the execution table, what is the system response after running 'npm create svelte@latest my-app'?

A Downloads and installs dependencies

B Starts development server

C Prompts for template and options

D Changes directory to project folder

💡 Hint

Check execution_table row 1 under 'System Response'

At which step does the development server start running?

A Step 2

B Step 4

C Step 3

D Step 5

💡 Hint

Look at execution_table 'Command/Action' and 'Result' columns

If you skip 'npm install', what will happen when you run 'npm run dev'?

A The server will fail to start due to missing packages

B The server will start normally

C The project folder will be deleted

D The browser will open automatically

💡 Hint

Refer to key_moments about the importance of 'npm install'

Concept Snapshot

Project setup with create-svelte:
1. Run 'npm create svelte@latest <project-name>' to scaffold.
2. Choose template and options when prompted.
3. Change into project folder with 'cd'.
4. Run 'npm install' to get dependencies.
5. Start dev server with 'npm run dev'.
6. Open browser at localhost:5173 to see app.

Full Transcript

To set up a new Svelte project, you start by running 'npm create svelte@latest' followed by your project name. This command scaffolds the project files and asks you to pick a template. Next, you move into the project folder using 'cd'. Before running the app, you must install dependencies with 'npm install'. After installation, you start the development server with 'npm run dev'. Finally, you open your browser to http://localhost:5173 to see the running Svelte app. Stopping the server ends your development session.
