Web Development

npm or npx? The two commands differ by one letter. Their jobs couldn't be more different. 👉 npm installs packages into your project. 👉 npx downloads a package, runs it, and removes it afterward unless it's already available. That's why you'll see this:

npx create-vite@latest

instead of:

npm install create-vite

You're only using create-vite once to generate a project. Keeping it installed afterward serves no purpose. 📖 A simple rule works almost every time:

✔️ If your application needs it to run, install it. ✔️ If you only need the tool for a one-time task, run it with npx.
