![NPM Stats](https://nodei.co/npm/hostparty.png?downloads=true&downloadRank=true&stars=true)

[![Build Status](https://travis-ci.org/drb/hostparty.svg)](https://travis-ci.org/drb/hostparty) [![npm version](https://badge.fury.io/js/hostparty.svg)](http://badge.fury.io/js/hostparty)

### Installing:

To use as a CLI tool, you can install hostparty globally.

`npm install -g hostparty`

Or, `require('hostparty')` in your own applications to use the API:

`npm install hostparty --save`

### API:

All API methods return thenable promises.

```javascript
let party = require('hostparty');


// add a couple of hosts mapping to ip 127.0.0.1
party.add('127.0.0.1', ['party-started.com', 'party-pooper.com']);


// see who we have in our hosts file
party.list().then((hosts)=>{

    // `hosts` is an object containing the ip as a key, and the hostnames(s) bound as an array
    // 127.0.0.1 party-started.com party-pooper.com
});


// remove the party pooper from its bound ip
party.purge('party-pooper.com');


// remove all entries pointing to ips 127.0.0.1 and 8.8.4.4
party.remove(['127.0.0.1', '8.8.4.4']);


// try and remove a protected IP
party
    .remove('::1')
    .then(()=>{
        console.log("All good");
    })
    .catch((e)=>{
        console.error('Error found [%s]. Try using the force flag.', e.message);
    });


// set options to change the default path, and override any warnings
party
    .setup({
        // override the path to the file
        path:   '~/my-own/hosts',
        // ignores validation
        force:  true
    })
    .remove('::1')
    .then(()=>{
        console.log("All good");
    });

```

### CLI Usage:

From hostparty --help:

```
  Usage: hostparty [options] [command]


  Commands:

    list [options] [hostname]      Outputs the hosts file with optional matching hostname.
    add [options] [ip] [hosts...]  Adds a new host(s) entry for an IP address.
    remove [options] [ips...]      Removes all entries for an IP address.
    purge [options] [hosts...]     Removes all host(s) specified.

  Options:

    -p, --path          Path to file (auto-detection is enabled by default)
    -f, --force         Disable any validation on protected methods
    -ng, --no-group     Don't group by IP
    -h, --help          Output usage information
    -V, --version       Output the version number
```

### Notes:

Some entries such as `::1` on OSX is protected from calls to `remove()` as this is a loopback address used by the operating system during the boot cycle. Purge is supported for hosts bound to the address, but a purge on `localhost` for this IP is protected unless the `--force` flag is used.
