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.
