What is cli?

sv is the official command-line tool for Svelte, a popular framework for building websites. Its main job is to help you get a new Svelte project up and running quickly. Instead of manually creating folders, configuration files, and writing boilerplate code from scratch, you simply run a command, and the tool sets everything up for you so you can start building your app right away. At a high level, the tool works through two main packages. The first is the core tool itself, which handles creating new projects and likely provides a guided setup process so you can choose what you need. The second package is a migration tool, which helps you update your existing Svelte projects when new versions of the framework come out. Upgrading a project can sometimes break things if old code isn't updated to match new standards, so the migration tool automates that process and fixes your code for you. This tool is for anyone building websites or applications with Svelte, from beginners setting up their very first project to experienced developers who want to skip the repetitive setup steps. For example, if you are starting a new business and want to build your product's website with Svelte, you would use this tool to generate a ready-to-go starting point. Later, when a new version of Svelte is released with better features, the migration tool ensures your existing project updates smoothly without requiring you to manually hunt down and fix broken code. One notable thing about the project is how the maintainers handle add-ons, extra features you can bolt onto your project. They are keeping the official add-ons in this repository to a very limited number, only accepting tools that are considered best-in-class and widely needed by the community. This means they are prioritizing a lean, reliable core experience rather than packing the tool with every possible feature, and they encourage the community to build and share their own add-ons independently.
