Who is this guy?

What am I talking about?

Like laser robots

And space suits

at NASA

And actual satellites

But mostly websites

80% of npm users are using it to build websites

10 billion downloads per month

520,000 packages

8.4 million users

Everybody ❤️ npm

"Dang, that's fast"

- everyone

npm install -g npm

Why modules?

Small modules enable big apps

Modules can

be re-used

npm init

npm install

package-lock.json

SemVer

2.34.13

Breaking

Feature

Fix

major
minor
patch

Why SemVer?

SemVer is built into npm

~3.5.3

^3.5.3

Automatic SemVer makes your team more efficient

The bigger you are, the more it helps

Libraries

vs

Applications

Libraries want SemVer

Applications prefer stability

package-lock.json best practices

package-lock.json benefits

npm 5 uses new features of the registry

npm Enterprise

Authentication and access control

Replication

Security

Discovery

Collaboration

npx

You can tell it's cool because it has an X in the name!

run scripts

{
  "name": "@seldo/some-package",
  "version": "1.0.0",
  ...
  "scripts": {
    "test": "mocha ./test/*.js",
    "start": "node ./index.js"
  }
}

Why use run scripts?

Version controlled development environments

Lifecycle events

publish:   prepublish, publish, postpublish
install:   preinstall, install, postinstall
uninstall: preuninstall, uninstall, postuninstall
version:   preversion, version, postversion
test:      pretest, test, posttest
stop:      prestop, stop, poststop
start:     prestart, start, poststart
restart:   prerestart, restart, postrestart

Husky

npm install husky

Automating best practices

Automation is a gigantic time saver

So automate already

Run scripts use your dev dependencies

npm install --save-dev

Dev dependencies are in path for run scripts

Use npx to run your dev dependencies directly

npx jest

Use npx to run

one-off comands

npx create-react-app

Use npx to try out new tooling

npx webpack@3.3

Other npx features

What else is new

in npm 5?

npm for front-end development

webpack

babel

Webpack and babel have 1000s of plugins

Use linters to improve your

code reviews

Wrapping up

Think of some questions.

There's swag in it for you!
