It’s common to add tools like Prettier or Webpack into a project, but you might want to try them out first before you fully integrate and configure them.
npx is a handy command line tool that comes bundled with npm, and you can use it to try out command line tools without needing to add them as a project dependency.
For example, if you want to give Prettier a spin to see which files in your project it would fix the formatting for, you can run:
npx prettier --check .
It’s a great way to quickly try things out!
