A simple script which forces you to select pnpm as the package manager and install prettier as devDep

#!/bin/bash
isPackageManagerSpecified="false";

for ((i=1; i<=$#; i++))
do
  nextArgumentIndex=$((i+1));
  if [[ "${!i}" == "--package-manager" ]] && [[ "${!nextArgumentIndex}" == "pnpm" ]];
  then
    isPackageManagerSpecified="true";
  fi
done

if [[ $isPackageManagerSpecified != "true" ]]
then
  echo "Please specify package manager";
  exit 1;
