This works for me

Install prettier:

npm init 
npm i prettier

Add following script in package.json:

"pretty": "prettier --write \"./**/*.{js,jsx,json}\"" 

In this case only, i need to format my .js .jsx and .json files.

Run script:

npm run pretty

The simplest solution that I have found is as below.

• Install prettier in vscode.
• Create the .prettierrc file and configure it the way you want.
• Run following command in vscode console.

npx prettier --write "**/*.ts" (Add the file type regex as per the need)
