Verdaccio is a lightweight private npm proxy registry built in Node.js

Wikipedia


Verdaccio is a proxy / registry for npm packages, on which you can publish private packages at the cost of the server it runs on. Here’s how’to setup Verdaccio on PantherX Server in 10 minutes.

Server setup

We’re starting out with a blank PantherX Server installation:

Loggin as root and get a SSL certificate:

guix package -i certbot
certbot certonly --standalone -d npm.domain.com

Next, back on your computer, prepare the server configuration. You can use the following as a template:

  • Add your SSH public key here: ssh-ed25519 AAAAC3DCaC1lZDI1NDS5AASAAIP7........
  • Adjust the target disk (target "/dev/sda"))) and (device "/dev/sda1")
    • On DigitalOcean VM’s thats usuall (target "/dev/vda"))) and (device "/dev/vda1")
    • You can refer to /etc/config.scm on the target machine to double-check
  • Replace all npm.domain.com with your domain
  • Adjust the target machine IP address: (host-name "192.168.1.100")
;; PantherX OS Server deployment template
;; for Digital Ocean
;;
;; Services: PostgreSQL, Redis, Nginx
;; Firewall: 22, 80, 443

;; Init via script in repo: px-install/pantherx-on-digitalocean.sh

To deploy this configuration, save and deploy:

guix deploy npm.domain.com.scm

Verdaccio setup

Loggin as panther on the target computer (or whatever you set as 2nd user) and install Verdaccio:

mkdir verdaccio
cd verdaccio/
npm install verdaccio
npm install forever

Try running it with:

$ node_modules/.bin/verdaccio 
 info --- Creating default config file in /home/panther/.config/verdaccio/config.yaml
 warn --- config file  - /home/panther/.config/verdaccio/config.yaml
 warn --- "crypt" algorithm is deprecated consider switch to "bcrypt". Read more: https://github.com/verdaccio/monorepo/pull/580                                                                                                            
 info --- plugin successfully loaded: verdaccio-htpasswd
 info --- plugin successfully loaded: verdaccio-audit
 warn --- http address - http://localhost:4873/ - verdaccio/5.15.4

If you have already setup the webserver, you can now open https://npm.domain.com and should see verdaccio.

If you get some errors, try restarting nginx:

  • Loggin as root
  • Run herd restart nginx

Once you confirm that the default works, it’s time to continue. You may stop Verdaccio for now.

Authentication

By default you will find the following in the config file (/home/panther/.config/verdaccio/config.yaml). Make sure to uncomment max_users and algorithm:

auth:
  htpasswd:
    file: ./htpasswd
    # Maximum amount of users allowed to register, defaults to "+inf".
    # You can set this to -1 to disable registration.
    max_users: -1 # In case you decide to prevent users from signing up themselves, you can set max_users: -1.
    # Hash algorithm, possible options are: "bcrypt", "md5", "sha1", "crypt".
    algorithm: bcrypt # by default is crypt, but is recommended use bcrypt for new installations
    # Rounds number for "bcrypt", will be ignored for other algorithms.
    # rounds: 10

For users to authenticate, you would add them to a new /home/panther/.config/verdaccio/htpasswd file that looks like this:

username1:$2b$10$6FxI9NgKBQv6t/gy5gF8IuaxN5BG9AcUDzyzW8VAGOgLfoYMqa3p
username2:$2b$10$ePqZz2NlqJFuu7VmCgsI.OvUhF0tVZFqPPGweeCZJBMJ/0yRljNe

Here’s how you can generate bcrypt password strings:

$ guix package -i python-bcrypt
$ python3 -c 'import bcrypt; print(bcrypt.hashpw(b"password", bcrypt.gensalt(rounds=10)))'
b'$2b$10$6FxI9NgKBQv6t/gy5gF8IuaxN5BG9AcUDzyzW8VAGOgLfoYMqa3p.'

Make sure to replace password with your desired secret.

Access

Our goal is to run a private repository, so we modify the packages section of the config (/home/panther/.config/verdaccio/config.yaml) to look like this:

packages:
  '@*/*':
    # scoped packages
    access: $authenticated
    publish: $authenticated
    unpublish: $authenticated
    proxy: npmjs

  '**':
    # allow all users (including non-authenticated users) to read and
    # publish all packages
    #
    # you can specify usernames/groupnames (depending on your auth plugin)
    # and three keywords: "$all", "$anonymous", "$authenticated"
    access: $authenticated

    # allow all known users to publish/publish packages
    # (anyone can register by default, remember?)
    publish: $authenticated
    unpublish: $authenticated

    # if package is not available locally, proxy requests to 'npmjs' registry
    proxy: npmjs

Run

node_modules/.bin/forever start node_modules/.bin/verdaccio

To check that the process is running:

$ node_modules/.bin/forever list
