## Install

Either download from [here](https://github.com/mailsvb/jsftpd/releases) or install via npm.

```shell
$ npm install jsftpd
```

## Quick start

To get an FTP server running quickly, the below code will get you started by allowing access for a single user.

```js
const { ftpd } = require('jsftpd')

const server = new ftpd({cnf: {username: 'john', password: 'doe', basefolder: '/tmp'}})

server.start()
```

## Documentation

The full documentation of the project is available [here](https://jsftpd.readthedocs.io/en/latest/).

The ftpd instance takes an object with two properties that allows for configuring the new instance.
- `tls` property object. Takes any configuration option as per node.js tls.createServer [options](https://nodejs.org/api/tls.html#tlscreateserveroptions-secureconnectionlistener)
- `cnf` property object. Takes jsftpd specific configuration items. See full documentation [here](https://jsftpd.readthedocs.io/en/latest/options.html#cnf)
- `hdl` property object. Takes handler functions for specific FTP commands. See full documentation [here](https://jsftpd.readthedocs.io/en/latest/options.html#hdl)
