How to install Browser-sync locally in a project on Mac?

Question

Node.js

installed globally and via sudo, but as I understand it, this is not a very good option judging from the official documentation:
"WARNING - do not use sudo! If you're running Mac OSX and encounter problems when trying to install Browsersync - either globally or locally, it's almost always because you have problems with NPM permissions.Checkout their docs for a guide on how to fix this once and for all - it only takes 2 minutes :)"

Answer 1

npm install browser-sync --save-dev
Run locally
Can be added to npm scripts for convenience.
