The verdaccio CLI is your go start the application.

## Commands

```bash
verdaccio --listen 4000 --config ~./config.yaml
```

Command | Default | Example | Description
--- | --- | --- | ---
--listen \ **-l** | 4873 |  -p 7000 | http port
--config \ **-c** | ~/.local/verdaccio/config.yaml | ~./config.yaml | the configuration file
--info \ **-i** | | | prints local environment information

## Default config file location

To locate the home directory, we rely on **$XDG_DATA_HOME** as a first choice and Windows environment we look for [APPDATA environment variable](https://www.howtogeek.com/318177/what-is-the-appdata-folder-in-windows/).

## Config file format

Config file should be YAML, JSON or NodeJS module. YAML format is detected by parsing config file extension (yaml or yml, case insensitive).

## Default storage location

We use **$XDG_DATA_HOME** environment variable as default to locate the storage by default which [should be the same](https://askubuntu.com/questions/538526/is-home-local-share-the-default-value-for-xdg-data-home-in-ubuntu-14-04) as $HOME/.local/share.
If you are using a custom storage, this location is irrelevant.

## Default database file location

The default database file location is in the storage location.
Starting with version 4.0.0, the database file name will be **.verdaccio-db.json** for a new installation of Verdaccio.
When upgrading an existing Verdaccio server, the file name will remain **.sinopia-db.json**.
