Who is this guy?

Laurie Voss

COO & co-founder, npm Inc.


This talk is about you

Three parts:

  1. What you should know about npm

  2. What npm knows about you

  3. The future of JavaScript

npm is popular

Part 1: what you should know about npm

JavaScript is enormously popular

Top 5 languages on GitHub

by number of pull requests opened

npm is the package manager for all JavaScript

But npm is especially for web developers


of the code in a modern web app comes from npm

npm is super fast now

npm install npm -g

Why not destroy the conference wifi by upgrading right now?

Is npm faster than Yarn?

npm 6

locks by default

3. npm ci will double the speed of your builds

npm ci

You can use

anywhere you used to use

npm install

and it will be twice as fast

npm Security

A bunch of new features

npm 6 has 2FA:

two-factor auth

Secure your npm account in 30 seconds:

npm Quick Audits

Just run npm install!

npm Quick Audit stats

3.5 million scans per week


npm audit

Just run in your current project:

npm audit

npm audit fix

Just run in your current project:

npm audit fix


npm audit fix --force

for the adventurous

Use npm because npm is safer than Yarn

Yarn to npm migration tool:

A user journey from Yarn back to npm:

BREAKING NEWS: Company recommends own product.

npm is a company that sells good and services that you will find useful

Part 2:

What npm knows about you

  • 1.5 billion log events per day
  • 16,000+ survey responses

Part 2A: demographics

Please stand up!

(If you can't stand up, raise a hand)

Sit down if you don't match the description.

Stay standing if you

use npm

Stay standing if you

write JavaScript that runs in browsers

Stay standing if you

write JavaScript

at work

Stay standing if you

are concerned about security of open source code

Stay standing if you

mostly taught yourself JavaScript

Stay standing if you

also write PHP or Java sometimes

Stay standing if you

work at a company that isn't considered a "tech company"

Stay standing if you

started using npm less than 2 years ago

Stay standing if you

use webpack

Stay standing if you

use babel

Stay standing if you

work on a React app

Stay standing if you

use TypeScript

So we know some stuff about you

npm users don't always write JavaScript

The programming language you pick is determined by the libraries available

Devs pick JavaScript because of npm

npm users are concerned about security

  • 77% are concerned
  • 52% said current tools aren't adequate

npm Enterprise can help your security

Part 2B:

the tools we use

I am about to make you angry

with graphs

Growth in context

Everything in npm grows

Share of registry

Front end frameworks

Frameworks never die; they only fade away


60% of npm users say they use React



Angular is seeing fewer downloads,

please don't yell at me about it.


The comeback kid


The next big thing?

The React ecosystem

React Router

React is a triumph of modular design




Back-end frameworks





This looks weird

Team A / Team B


What tools do we use?


46% of npm users are using TypeScript


Say what?!


So about ESLint...

The ESLint Credentials Harvester


npm Security

in action


Take JavaScript security seriously



Splitting developers by experience

Best practices come with experience

Security is associated with experience

Part 3:

the future of JavaScript

Learning from history:

nothing last forever

jQuery, we hardly knew ye.

Use React

Ill-advised prediction

If people start re-using React modules, React will live forever

What about web components?

Web components would be great if they worked but they don't, yet.

Don't @ me.

What about that slowdown in React?

The best framework is always the one with the most users.

What if not React?

"I can't use React because Facebook kicked my puppy!"

  • Angular has huge corporate backing
  • Vue has a lot of growth momentum
  • Ember has a bit of both
  • I like Next.js

Learn GraphQL

Ill-advised prediction

You will be bundling, transpiling and linting for quite some time

Ill-advised prediction

Use TypeScript

Ill-advised prediction

What happens to npm in the future?

npm is not only JavaScript

and it hasn't been for some time

WASM is coming

WASM is already here

npm is for the web

The future looks fun

The web will remain under construction

Thank you!
