title: 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 is created the very first time you run `verdaccio`.

## Default Configuration

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

```yaml
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 means each property and the different options.

### Storage

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

```yaml
storage: ./storage
```

### Authentification

The authentification set up is done here, the default auth is based on `htpasswd` and is built-in. You can modify this behaviour via [plugins](plugins.md). For more information about this section read the [auth page](auth.md).

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

### Web UI

This properties allow you to modify the look and feel of the web UI. For more information about this section read the [web ui page](web.md).

```yaml
web:
  enable: true
  title: Verdaccio
  logo: logo.png
```

### Uplinks

Uplinks is the ability of the system to fetch packages from remote registries when those packages are not available locally. For more information about this section read the [uplinks page](uplinks.md).

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

### Packages

Packages allow the user how the packages are gonna be accessed. For more information about this section read the [packages page](packages.md).

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

## Advanced Settings

### Offline Publish

By default `verdaccio` does not allow to publish when the client is offline, that behavior can be overridden set it in to *true*.

```yaml
publish:
  allow_offline: false
```

<small>Since: <code>verdaccio@2.3.6</code> due <a href="https://github.com/verdaccio/verdaccio/pull/223">#223</a></small>

### URL Prefix

```yaml
url_prefix: https://dev.company.local/verdaccio/
```

Since: `verdaccio@2.3.6` due [#197](https://github.com/verdaccio/verdaccio/pull/197)

### Max Body Size

By default the maximum body size for a JSON document is `1mb`, if you run in errors as `"request entity too large"` you may increase this value.

```yaml
max_body_size: 1mb
```

### Listen Port

`verdaccio` runs by default in the port `4873`. Change the port can be done via [cli](cli.md) or in the configuration file, the following options are valid.

```yaml
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` enough with set your `listen` domain with the protocol *https://*. For more information about this section read the [ssl page](ssl.md).

```yaml
https:
  key: path/to/server.key
  cert: path/to/server.crt
  ca: path/to/server.pem
```

### Notifications

Enable notifications to three party tools is fairly easy via web hooks. For more information about this section read the [notifications page](notifications.md).

```yaml
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"}'
```
