How to Install Svelte: Quick Setup Guide

To install Svelte, first ensure you have Node.js installed, then run npm create svelte@latest my-app in your terminal to create a new project. After that, navigate into your project folder and run npm install to install dependencies, then npm run dev to start the development server.

Syntax

Use the following commands to install and start a Svelte project:

• npm create svelte@latest my-app: Creates a new Svelte project named my-app.
• cd my-app: Moves into the project folder.
• npm install: Installs all project dependencies.
• npm run dev: Starts the development server to preview your app.

bash

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

Output

Common Pitfalls

Missing Node.js: Svelte requires Node.js; install it from nodejs.org before running commands.
Wrong directory: Always cd into your project folder before installing dependencies or running the dev server.
Old npm version: Use npm version 7 or higher for best compatibility.
Skipping npm install: This step is necessary to download all packages your project needs.

bash

npm create svelte@latest my-app
# Wrong: running npm run dev outside project folder
npm run dev

# Correct:
cd my-app
npm install
npm run dev

Key Takeaways

Install Node.js before starting with Svelte.

Use npm create svelte@latest to generate a new project.

Always run npm install inside your project folder before starting.

Use npm run dev to launch the development server and preview your app.

Check your terminal output for the local URL to open your app in a browser.
