Run prettier on all files in a directory with the given extension(s)

prettierFormatAll.md

1. Install prettier
2. Make a .prettierignore file, and add directories you'd like prettier to not format, for example: **/node_modules
3. Run prettier --write "**/*.{ts,js,css,html,insertAnyFilesExtensionHere}" **Don't forget the quotes.

You could also add this to your projects package.json under scripts to simply run npm run prettier to format your code before committing it:

{ ... "scripts": { "prettier": "prettier --write '**/*.{ts,js,css,html}'" } ... }
