Docker vs npm: What are the differences?

Developers describe Docker as "Enterprise Container Platform for High-Velocity Innovation". The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere. On the other hand, npm is detailed as "The package manager for JavaScript". npm is the command-line interface to the npm ecosystem. It is battle-tested, surprisingly flexible, and used by hundreds of thousands of JavaScript developers every day.

Docker can be classified as a tool in the "Virtual Machine Platforms & Containers" category, while npm is grouped under "Front End Package Manager".

"Rapid integration and build up", "Isolation" and "Open source" are the key factors why developers consider Docker; whereas "Best package management system for javascript", "Open-source" and "Great community" are the primary reasons why npm is favored.

Docker and npm are both open source tools. Docker with 54K GitHub stars and 15.6K forks on GitHub appears to be more popular than npm with 17.2K GitHub stars and 3.17K GitHub forks.

According to the StackShare community, Docker has a broader approval, being mentioned in 3524 company stacks & 3443 developers stacks; compared to npm, which is listed in 2642 company stacks and 2666 developer stacks.

What are some alternatives to Docker and npm?
LXC
LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
rkt
Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.
Kubernetes
Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
Cloud Foundry
Cloud Foundry is an open platform as a service (PaaS) that provides a choice of clouds, developer frameworks, and application services. Cloud Foundry makes it faster and easier to build, test, deploy, and scale applications.
Vagrant
Vagrant provides the framework and configuration format to create and manage complete portable development environments. These development environments can live on your computer or in the cloud, and are portable between Windows, Mac OS X, and Linux.

Reviews of Docker and npm

Review ofDockerDocker

Docker is the new kid on the block disrupting virtualization nowadays. You're able to save up to 70% of your development cost on AWS (or any other cloud) switching to Docker. For example instead of paying for many small VMs you can spin up a large one with many Docker containers to drastically lower your cost. That alone is only one of the reasons why Docker is the future and it's not even the best feature: isolation, testa­bil­i­ty, re­pro­ducibil­i­ty, standardization, security, and upgrading / down­grad­ing / ap­pli­ca­tion versions to name a few. You can spin up 1000's of Docker containers on an ordinary Laptop, but you would have trouble spinning up 100's of VMs. If you haven't already checked out Docker you're missing out on a huge opportunity to join the movement that will change development/production environments forever

Review ofDockerDocker

The support for macOS is a fake.

I can't work with docker in macOS because de network and comunications with the container don't works correctly.

Currently experimenting. The idea is to isolate any services where I'm not confident yet in their security/quality. The hope is that if there is an exploit in a given service that an attacker won't be able break out of the docker container and cause damage to my systems.

An example of a service I would isolate in a docker container would be a minecraft browser map application I use. I don't know who wrote it, I don't know who's vetting it, I don't know the source code. I would feel a lot better putting this in a container before I expose it to the internet.

I believe I will follow this process for anything that's not properly maintained (not in an trusted apt-repo or some other sort of confidence)

We are testing out docker at the moment, building images from successful staging builds for all our APIs. Since we operate in a SOA (not quite microservices), developers have a dockerfile that they can run to build the entirety of our api infrastructure on their machines. We use the successful builds from staging to power these instances allowing them to do some more manual integration testing across systems.

Each component of the app was launched in a separate container, so that they wouldn't have to share resources: the front end in one, the back end in another, a third for celery, a fourth for celery-beat, and a fifth for RabbitMQ. Actually, we ended up running four front-end containers and eight back-end, due to load constraints.

Utilize npm private module to package shared library for different React / React Native clients. Shareable code goes here. Basically deliver Redux Store with Firebase integration and business logic in a library. Each React app utilizes this while delivering a device/target specific UI.

Linux containers are so much more lightweight than VMs which is quite important for my limited budget. However, Docker has much more support and tooling for it unlike LXC, hence why I use it. rkt is interesting, although I will probably stick with Docker due to being more widespread.

We are running primarily as a micro-services platform and Docker lets us iterate on these smaller units consistently from dev to staging to production. It is also integral to our continuous deployment system for rolling out or rolling back new features.

If you're using Node or Gulp, you can't help but use NPM in some form or another. Fortunately that's never a bad thing with the massive package repository and glowing ecosystem making it a breeze to work with.

We manages all of our packages, including Angular JS through npm. It is a very quick way of downloading / installing packages into your project.

Module is published as bpost on the npm registry. Tasks for the module are also defined as npm run tasks with commit hooks for git

It's the front-end version of Composer, so is pretty essential to pull in packages that can be tracked and kept up to date.
