[NPM] Publish npm packages using npm publish

In this lesson we will publish our package. We will first add a prepublish script that runs our buildscript; this will ensure the built folder gets added to npm when published. We will also add a .npmignore so that only our built files get installed. We need to run npm adduser to log in to an npm account. We can then run npm publish to publish our package and view it on npm.

Note: if you want to actually publish the package from this course, you'll need to rename it since sensitive-words is already taken. You can use a scoped package name for this as well.

Inside our .npmigore:

src // ignore, therefore users install our package will not include src folder

script:

"prepublish": "npm run build",

Add prepublish script, so that everytime we publish the lib, will make sure use the latest code.
