Best Practices

The following guide is a list of the best practices collected and that we usually recommend to all users. Do not take this guide as mandatory, you might pick some of them according your needs.

Feel free to suggest your best practices with the Verdaccio community.

Private Registry

Vous pouvez ajouter des utilisateurs et gérer quels utilisateurs peuvent accéder à quels paquets.

It is recommended that you define a prefix for your private packages, for example local-* or scoped @my-company/*, so all your private things will look like this: local-foo. De cette façon, vous pouvez clairement séparer les paquets publiques et privés.

yaml
  packages:
    '@my-company/*':
      access: $all
      publish: $authenticated
     'local-*':
      access: $all
      publish: $authenticated
    '@*/*':
      access: $all
      publish: $authenticated
    '**':
      access: $all
      publish: $authenticated

Always remember, the order of packages access is important, packages are mached always top to bottom.

Utilisation des paquets publics à partir de npmjs.org

Si un paquet n'existe pas dans l'archive, le serveur essaiera de le récupérer à partir de npmjs.org. Si npmjs.org ne fonctionne pas, il ne fournira les paquets mis en cache que s'il n'y avait pas d'autres paquets. Verdaccio will download only what's needed (= requested by clients), and this information will be cached, so if client will ask the same thing second time, it can be served without asking npmjs.org for it.

Example:

If you successfully request express@4.0.1 from this server once, you'll able to do that again (with all it's dependencies) anytime even if npmjs.org is down. But say express@4.0.0 will not be downloaded until it's actually needed by somebody. And if npmjs.org is offline, this server would say that only express@4.0.1 (= only what's in the cache) is published, but nothing else.

Annuler les paquets publiques

If you want to use a modified version of some public package foo, you can just publish it to your local server, so when your type npm install foo, it'll consider installing your version.

Il y a deux options ici:

1. You want to create a separate fork and stop synchronizing with public version.

   Si vous voulez faire cela, vous devriez modifier votre fichier de configuration pour que verdaccio ne fasse plus de demande à propos de ce paquet pour npjms. Add a separate entry for this package to config.yaml and remove npmjs from proxy list and restart the server.

   packages:
     '@my-company/*':
       access: $all
       publish: $authenticated
       # comment it out or leave it empty
       # proxy:
   

   When you publish your package locally, you should probably start with version string higher than existing one, so it won't conflict with existing package in the cache.

2. Vous souhaitez utiliser temporairement votre propre version, mais revenir à la version public dès sa mise à jour.

   In order to avoid version conflicts, you should use a custom pre-release suffix of the next patch version. For example, if a public package has version 0.1.2, you can upload 0.1.3-my-temp-fix.

   npm version 0.1.3-my-temp-fix
   npm --publish --tag fix --registry http://localhost:4873
   

   This way your package will be used until its original maintainer updates his public package to 0.1.3.

Security

The security starts in your environment, for such thing we totally recommend read 10 npm Security Best Practices and follow the recommendation.

Paquet d'accès

By default all packages are you publish in Verdaccio are accessible for all public, we totally recommend protect your registry from external non authorized users updating access property to $authenticated.

  packages:
    '@my-company/*':
      access: $authenticated
      publish: $authenticated
    '@*/*':
      access: $authenticated
      publish: $authenticated
    '**':
      access: $authenticated
      publish: $authenticated

In that way, nobody will take advance of your registry unless is authorized and private packages won't be displayed in the User Interface.

Server

Secured Connections

Using HTTPS is a common recomendation, for such reason we recommend read the SSL section to make Verdaccio secure or using a HTTPS reverse proxy on top of Verdaccio.

Expiring Tokens

In verdaccio@3.x the tokens have no expiration date. For such reason we introduced in the next verdaccio@4.x the JWT feature PR#896

security:
  api:
    jwt:
      sign:
        expiresIn: 15d
        notBefore: 0
  web:
    sign:
      expiresIn: 7d

Using this configuration will override the current system and you will be able to control how long the token will live.

Using JWT also improves the performance with authentication plugins, the old system will perform an unpackage and validating the credentials in each request, while JWT will rely on the token signature avoiding the overhead for the plugin.

As a side note, at npmjs the token never expires.
