Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Published

Private npm repository server

Readme

A lightweight private npm proxy registry

verdaccio is a fork of sinopia. It aims to keep backwards compatibility with sinopia, while keeping up with npm changes.

CircleCI npm version badge downloads badge Gitter chat

It allows you to have a local npm private registry with zero configuration. You don't have to install and replicate an entire database. Verdaccio keeps its own small database and, if a package doesn't exist there, it asks any other registry (npmjs.org) for it keeping only those packages you use.

Quick Links

Introduction

Use private packages

If you want to use all benefits of npm package system in your company without sending all code to the public, and use your private packages just as easy as public ones.

Cache npmjs.org registry

If you have more than one server you want to install packages on, you might want to use this to decrease latency (presumably "slow" npmjs.org will be connected to only once per package/version) and provide limited failover (if npmjs.org is down, we might still find something useful in the cache) or avoid issues like How one developer just broke Node, Babel and thousands of projects in 11 lines of JavaScript.

Override public packages

If you want to use a modified version of some 3rd-party package (for example, you found a bug, but maintainer didn't accept pull request yet), you can publish your version locally under the same name.

See in detail each of these use cases.

Get Started

Prerequisites

  • Node.js >= 4.6.1
  • npm or yarn

Installation and starting (application will create default config in config.yaml you can edit later)

npm install --global verdaccio

Run in your terminal

verdaccio

You would need set some npm configuration, this is optional.

$ npm set registry http://localhost:4873/
# if you use HTTPS, add an appropriate CA information
# ("null" means get CA list from OS)
$ npm set ca null

Now you can navigate to http://localhost:4873/ where your local packages will be listed and can be searched.

Warning: Verdaccio does not currently support PM2's cluster mode, running it with cluster mode may cause unknown behavior.

Alpha

⚠️⚠️ Please, help us to test the version 3.x in order to release a stable version soon. Do never test with your original storage folder, do always a backup ⚠️⚠️

If you are an adventurous developer you can use and install the latest beta version, this is a non stable version, I'd recommend only use for testing purporses.

$ npm install -g verdaccio@alpha

or using docker

$ docker run -it --rm --name verdaccio -p 4873:4873 verdaccio/verdaccio:alpha

Publishing Private Packages

Create an user and log in

npm adduser --registry http://localhost:4873

Publish your package

npm publish --registry http://localhost:4873

This will prompt you for user credentials which will be saved on the verdaccio server.

  • Starring (npm star, npm unstar) - not supported, doesn't make sense in private registry
  • Ping (npm ping) - supported
