How to use files with multiple extensions with Prettier?

Just found solution. Following command will target both ts and tsx:

prettier --write "./src/**/*.{ts,tsx}"

Prettier is using Glob syntax which is syntax similar to Regex, used in shell.

See GLOB syntax details: https://github.com/isaacs/node-glob/blob/master/README.md#glob-primer

If you want to run prettier command on multiple paths with multiple extensions use the following command:

prettier --write "src/**/*.{ts,tsx,js,jsx}" "pages/**/*.{ts,tsx,js,jsx}" "server/**/*.js"
