How to automatically run Prettier on all files in a project

Dec 5, 2023

Learn how to run Prettier across every file in your project by adding a .prettierrc config and running npx prettier -w . to format them all at once.

Create a .prettierrc file in your project, for example

{
  "tabWidth": 2,
  "useTabs": false,
  "semi": false
}

Then run

npx prettier -w .

If you just need to tidy one snippet before committing, I built a free code beautifier that formats HTML, CSS, and JavaScript in the browser.
