Configuration File

This file is the cornerstone of Verdaccio where you can modify the default behaviour, enable plugins and extend features.

A default configuration file config.yaml is created the very first time you run verdaccio.

Default Configuration​

The default configuration has support for scoped packages and allows any user to access all packages, but only authenticated users to publish.

storage: ./storage
auth:
  htpasswd:
    file: ./htpasswd
uplinks:
  npmjs:
    url: https://registry.npmjs.org/
packages:
  '@*/*':
    access: $all
    publish: $authenticated
    proxy: npmjs
  '**':
    proxy: npmjs
log: { type: stdout, format: pretty, level: http }

Sections​

The following sections explain what each property means and their different options.

Storage​

Is the location of the default storage. Verdaccio is by default based on local file system.

storage: ./storage

Released at v5.6.0: The environment variable VERDACCIO_STORAGE_PATH could be used to replace the location of the storage (only for the default storage, does not apply to plugins unless it is implemented independently).

The .verdaccio-db database​

The tiny database is used to store private packages published by the user. The database is based on a JSON file that contains the list of private packages published and the secret token used for the token signature. It is created automatically when starting the application for the first time.

The location of the database is based on the config.yaml folder location, for instance:

If the config.yaml is located in /some_local_path/config.yaml, the database will be created in /some_local_path/storage/.verdaccio-db.

The .verdaccio-db file database is only available if user does not use a custom storage, by default verdaccio uses a tiny database to store private packages the storage property is defined in the config.yaml file. The location might change based on your operating system. Read the CLI section for more details about the location of files.

The structure of the database is based in JSON file, for instance:

{
  "list": ["package1", "@scope/pkg2"],
  "secret": "secret_token_32_characters_long"
}
  • list: Is an array with the list of the private packages published, any item on this list is considered being published by the user.
  • secret: The secret field is used for the token signature and verification, either for JWT or legacy token signature.

Plugins​

Is the location of the plugin directory. Useful for Docker/Kubernetes-based deployments.

plugins: ./plugins

Authentication​

The authentication setup is done here. The default auth is based on htpasswd and is built in. You can modify this behaviour via plugins. For more information about this section read the auth page.

auth:
  htpasswd:
    file: ./htpasswd
    max_users: 1000

Token signature​

The default token signature is based on the Advanced Encryption Standard (AES) with the algorithm aes-256-ctr, known as legacy. It's important to note that legacy tokens are not designed to expire. If expiration functionality is needed, it is recommended to use JSON Web Tokens (JWT) instead.

Security​

The security block permits customization of the token signature with two options. The configuration is divided into two sections, api and web. When using JWT on api, it must be defined; otherwise, the legacy token signature (aes192) will be utilized.

How to the token is generated?​

The token signature requires a secret token generated by custom plugin that creates the .verdaccio-db database or in case a custom storage is used, the secret token is fetched from the plugin implementation itself. In any case the secret token is required to start the application.

Legacy Token Signature​

The legacy property is used to enable the legacy token signature. By default is enabled. The legacy feature only applies to the API, the web UI uses JWT by default.

info

The migrateToSecureLegacySignature property is true by default on 6.x versions or higher and could be disabled but is not recommended otherwise will cause issues using Node.js 22 or higher.

# This configuration is the default one only displayed for reference,
# no need to define it in your config file.
security:
  api:
    legacy: true # by default is true even if this section is not defined
    migrateToSecureLegacySignature: true # will generate a new secret token if the length is 64 characters

JWT Token Signature​

To enable a new JWT (JSON Web Tokens) signature, the jwt block needs to be added to the api section; jwt is utilized by default in web.

By using the JWT signature is also possible to customize the signature and the token verification with your own properties.

security:
  api:
    legacy: true
    migrateToSecureLegacySignature: true # will generate a new secret token if the length is 64 characters
    jwt:
      sign:
        expiresIn: 29d
      verify:
        someProp: [value]
   web:
     sign:
       expiresIn: 1h # 1 hour by default
     verify:
        someProp: [value]

Server​

A set of properties to modify the behavior of the server application, specifically the API (Express.js).

You can specify HTTP/1.1 server keep alive timeout in seconds for incomming connections. A value of 0 makes the http server behave similarly to Node.js versions prior to 8.0.0, which did not have a keep-alive timeout. WORKAROUND: Through given configuration you can workaround following issue https://github.com/verdaccio/verdaccio/issues/301. Set to 0 in case 60 is not enough.

server:
  keepAliveTimeout: 60

Web UI​

This property allow you to modify the look and feel of the web UI. For more information about this section read the web UI page.

web:
  enable: true
  title: Verdaccio
  logo: logo.png
  scope:

Uplinks add the ability to fetch packages from remote registries when those packages are not available locally. For more information about this section read the uplinks page.

uplinks:
  npmjs:
    url: https://registry.npmjs.org/

Packages​

This section allows you to control how packages are accessed. For more information about this section read the packages page.

packages:
  '@*/*':
    access: $all
    publish: $authenticated
    proxy: npmjs

Advanced Settings​

Offline Publish​

By default verdaccio does not allow you to publish packages when the client is offline. This can be can be overridden by setting this value to true.

publish:
  allow_offline: false
Since: `verdaccio@2.3.6` due [#223](https://github.com/verdaccio/verdaccio/pull/223)

URL Prefix​

The prefix is intended to be used when the server runs behinds the proxy and won't work properly if is used without a reverse proxy, check the reverse proxy setup page for more details.

The internal logic builds correctly the public url, validates the host header and and bad shaped url_prefix.

eg: url_prefix: /verdaccio, url_prefix: verdaccio/, url_prefix: verdaccio would be /verdaccio/

url_prefix: /verdaccio/

The new VERDACCIO_PUBLIC_URL is intended to be used behind proxies, this variable will be used for:

  • Used as base path to serve UI resources as (js, favicon, etc)
  • Used on return metadata dist base path
  • Ignores host and X-Forwarded-Proto headers
  • If url_prefix is defined would be appened to the env variable.
VERDACCIO_PUBLIC_URL='https://somedomain.org';
url_prefix: '/my_prefix'

// url -> https://somedomain.org/my_prefix/

VERDACCIO_PUBLIC_URL='https://somedomain.org';
url_prefix: '/'

// url -> https://somedomain.org/

VERDACCIO_PUBLIC_URL='https://somedomain.org/first_prefix';
url_prefix: '/second_prefix'

// url -> https://somedomain.org/second_prefix/'

User Agent​

Since: `verdaccio@5.4.0`

The user agent is disabled by default, in exchange the user agent client (package manager, browser, etc ...) is being bypassed to the remote. To enable the previous behaviour use boolean values.

user_agent: true
user_agent: false
user_agent: 'custom user agent'

User Rate Limit​

Since: [verdaccio@5.4.0](https://github.com/verdaccio/verdaccio/releases/tag/v5.4.0)

Add default rate limit to user endpoints, npm token, npm profile, npm login/adduser and login website to 100 request peer 15 min, customizable via:

userRateLimit:
  windowMs: 50000
  max: 1000

Additonal configuration (only feature flags) is also possible via the middleware docs.

Max Body Size​

By default the maximum body size for a JSON document is 10mb, if you run into errors that state "request entity too large" you may increase this value.

max_body_size: 10mb

Listen Port​

verdaccio runs by default on the port 4873. Changing the port can be done via CLI or in the configuration file. The following options are valid:

listen:
# - localhost:4873            # default value
# - http://localhost:4873     # same thing
# - 0.0.0.0:4873              # listen on all addresses (INADDR_ANY)
# - https://example.org:4873  # if you want to use https
# - "[::1]:4873"                # ipv6
# - unix:/tmp/verdaccio.sock    # unix socket

HTTPS​

To enable https in verdaccio it's enough to set the listen flag with the protocol https://. For more information about this section read the SSL page.

https:
  key: ./path/verdaccio-key.pem
  cert: ./path/verdaccio-cert.pem
  ca: ./path/verdaccio-csr.pem

Proxy​

Proxies are special-purpose HTTP servers designed to transfer data from remote servers to local clients.

http_proxy and https_proxy​

If you have a proxy in your network you can set a X-Forwarded-For header using the following properties:

http_proxy: http://something.local/
https_proxy: https://something.local/

no_proxy​

This variable should contain a comma-separated list of domain extensions that the proxy should not be used for.

no_proxy: localhost,127.0.0.1

Notifications​

Enabling notifications to third-party tools is fairly easy via webhooks. For more information about this section read the notifications page.

notify:
  method: POST
  headers: [{ 'Content-Type': 'application/json' }]
  endpoint: https://usagge.hipchat.com/v2/room/3729485/notification?auth_token=mySecretToken
  content: '{"color":"green","message":"New package published: * {{ name }}*","notify":true,"message_format":"text"}'

For more detailed configuration settings, please check the source code.

Logger​

Two logger types are supported, you may chose only one of them:

console output (the default)​

log: { type: stdout, format: pretty, level: http }

file output​

log: { type: file, path: verdaccio.log, level: info }

For full information - see here: Features/logger

Audit​

Since: `verdaccio@3.0.0`

npm audit is a new command released with npm 6.x. Verdaccio includes a built-in middleware plugin to handle this command.

If you have a new installation it comes by default, otherwise you need to add the following props to your config file

middlewares:
  audit:
    enabled: true

Experiments​

This release includes a new property named experiments that can be placed in the config.yaml and is completely optional.

We want to be able to ship new things without affecting production environments. This flag allows us to add new features and get feedback from the community who decides to use them.

The features under this flag might not be stable or might be removed in future releases.

Here is one example:

experiments:
  changePassword: false

To disable the experiments warning in the console, you must comment out the whole experiments section.

Config Builder API​

After version v5.23.1 the new advanced configuration builder API is available. The API is a flexible way to generate programmatically configuration outputs either in JSON or YAML using the builder pattern, for example:

import { ConfigBuilder } from 'verdaccio';

const config = ConfigBuilder.build();
config
  .addUplink('upstream', { url: 'https://registry.upstream.local' })
  .addUplink('upstream2', { url: 'https://registry.upstream2.local' })
  .addPackageAccess('upstream/*', {
    access: 'public',
    publish: 'foo, bar',
    unpublish: 'foo, bar',
    proxy: 'some',
  })
  .addLogger({ level: 'info', type: 'stdout', format: 'json' })
  .addStorage('/tmp/verdaccio')
  .addSecurity({ api: { legacy: true } });

// generate JSON object as output
config.getConfig();

// generate output as yaml
config.getAsYaml();
