This guide concludes by demonstrating how to install and utilize a pre-existing npm project. This is a common practice, significantly simplifying development compared to manual configuration of individual components. We'll use a real-world SvelteKit static blog starter project as an example.

A Real-World Example: SvelteKit Static Blog Starter
This guide uses a SvelteKit static blog starter project. This project, pre-configured with numerous packages, effectively demonstrates the process. (Note: Prior SvelteKit knowledge isn't required.) SvelteKit leverages Vite, an npm package providing modern build tools and a fast development server.
Cloning the Project
Cloning, essentially copying the project, can be done in two ways:
- GitHub UI: Navigate to the GitHub repository, click the "Code" dropdown, and select "Download ZIP."
- Command Line: Using the command line, navigate to your desired project directory and execute:
npx degit https://github.com/josh-collinsworth/sveltekit-blog-starter.git sveltekit-blog-starter
npx degit
clones the project without Git history.
After cloning, a sveltekit-blog-starter
folder is created. Open it in your code editor, open a terminal, and run npm install
(or npm i
). Any vulnerability warnings can be safely ignored for this demonstration project.
Running the Server and Making Changes
The package.json
file contains the development server command:
npm run dev
Executing this command starts the server (accessible at http://localhost:3000
). Changes to files (Sass, Markdown, Svelte components) are reflected instantly in the browser.
Understanding Imports
This section highlights the importance of imports in npm projects. The guide showcases both ES6 imports (the modern standard) and the older CommonJS style. The key is that npm handles the resolution of package imports, simplifying development. ES6 imports require a bundler/compiler for processing.
Building the Final Site
Most npm projects have two main phases: development and production build. The command:
npm run build
creates a production-ready build
folder containing optimized static files (HTML, CSS, JavaScript). npm run preview
allows viewing the built site.
Modern Deployment
Modern deployment often integrates with services like Netlify or Vercel, automating the build and deployment process upon code pushes to the main branch.
Conclusion
This guide comprehensively covered npm, from its fundamentals to installing and utilizing existing projects. The focus was on practical application and understanding, providing a solid foundation for further exploration. ← Chapter 8 Guide chapters

Linking CSS files to HTML can be achieved by using elements in part of HTML. 1) Use tags to link local CSS files. 2) Multiple CSS files can be implemented by adding multiple tags. 3) External CSS files use absolute URL links, such as. 4) Ensure the correct use of file paths and CSS file loading order, and optimize performance can use CSS preprocessor to merge files.

Choosing Flexbox or Grid depends on the layout requirements: 1) Flexbox is suitable for one-dimensional layouts, such as navigation bar; 2) Grid is suitable for two-dimensional layouts, such as magazine layouts. The two can be used in the project to improve the layout effect.

The best way to include CSS files is to use tags to introduce external CSS files in the HTML part. 1. Use tags to introduce external CSS files, such as. 2. For small adjustments, inline CSS can be used, but should be used with caution. 3. Large projects can use CSS preprocessors such as Sass or Less to import other CSS files through @import. 4. For performance, CSS files should be merged and CDN should be used, and compressed using tools such as CSSNano.
