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
logs:
- { 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

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

Security

Since: `verdaccio@4.0.0` [#168](https://github.com/verdaccio/verdaccio/pull/168)

The security block allows you to customise the token signature. To enable a new JWT (JSON Web Tokens) signature you need to add the block jwt to the api section; web uses jwt by default.

The configuration is separated in two sections, api and web. To use JWT on api it has to be defined, otherwise the legacy token signature (aes192) will be used. For JWT you might want to customize the signature and the token verification with your own properties.

security:
api:
legacy: true
jwt:
sign:
expiresIn: 29d
verify:
someProp: [value]
web:
sign:
expiresIn: 7d # 7 days by default
verify:
someProp: [value]

We highly recommend move to JWT since legacy signature (aes192) is deprecated and will disappear in future versions.

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.

url_prefix: /verdaccio/

Verdaccio 5 has an improved prefix behaviour and the VERDACCIO_PUBLIC_URL is available for use, learn how to here.

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.

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.
