Use Babel as Watcher in PhpStorm

First, we need to install babel-cli globally

Open terminal and say

npm install -g @babel/core @babel/cli

Then, you will need a preset that babel will follow

for now, we will use preset-env:

npm install -g @babel/preset-env

We will check if / where preset-env is installed

which @babel/preset-env

It may return nothing, but in my OS X, the location was:

/usr/local/lib/node_modules/@babel/preset-env

Make sure that in Program you may have

/usr/local/lib/node_modules/@babel/cli/bin/babel.js

Then in Arguments

$FilePathRelativeToProjectRoot$ --no-babelrc --out-dir dist --source-maps --presets "/usr/local/lib/node_modules/@babel/preset-env"
