## API

var bonjour = require('bonjour')([options])
|
||
|
|
```
|
||
|
|
|
||
|
|
The `options` are optional and will be used when initializing the
|
||
|
|
underlying multicast-dns server. For details see [the multicast-dns
|
||
|
|
documentation](https://github.com/mafintosh/multicast-dns#mdns--multicastdnsoptions).
|
||
|
|
|
||
|
|
### Publishing
|
||
|
|
|
||
|
|
#### `var service = bonjour.publish(options)`
|
||
|
|
|
||
|
|
Publishes a new service.
|
||
|
|
|
||
|
|
Options are:
|
||
|
|
|
||
|
|
- `name` (string)
|
||
|
|
- `host` (string, optional) - defaults to local hostname
|
||
|
|
- `port` (number)
|
||
|
|
- `type` (string)
|
||
|
|
- `subtypes` (array of strings, optional)
|
||
|
|
- `protocol` (string, optional) - `udp` or `tcp` (default)
|
||
|
|
- `txt` (object, optional) - a key/value object to broadcast as the TXT
|
||
|
|
record
|
||
|
|
|
||
|
|
IANA maintains a [list of official service types and port
|
||
|
|
numbers](http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml).
|
||
|
|
|
||
|
|
#### `bonjour.unpublishAll([callback])`
|
||
|
|
|
||
|
|
Unpublish all services. The optional `callback` will be called when the
|
||
|
|
services have been unpublished.
|
||
|
|
|
||
|
|
#### `bonjour.destroy()`
|
||
|
|
|
||
|
|
Destroy the mdns instance. Closes the udp socket.
|
||
|
|
|
||
|
|
### Browser
|
||
|
|
|
||
|
|
#### `var browser = bonjour.find(options[, onup])`
|
||
|
|
|
||
|
|
Listen for services advertised on the network. An optional callback can
|
||
|
|
be provided as the 2nd argument and will be added as an event listener
|
||
|
|
for the `up` event.
|
||
|
|
|
||
|
|
Options (all optional):
|
||
|
|
|
||
|
|
- `type` (string)
|
||
|
|
- `subtypes` (array of strings)
|
||
|
|
- `protocol` (string) - defaults to `tcp`
|
||
|
|
- `txt` (object) - passed into [dns-txt
|
||
|
|
module](https://github.com/watson/dns-txt) contructor. Set to `{
|
||
|
|
binary: true }` if you want to keep the TXT records in binary
|
||
|
|
|
||
|
|
#### `var browser = bonjour.findOne(options[, callback])`
|
||
|
|
|
||
|
|
Listen for and call the `callback` with the first instance of a service
|
||
|
|
matching the `options`. If no `callback` is given, it's expected that
|
||
|
|
you listen for the `up` event. The returned `browser` will automatically
|
||
|
|
stop it self after the first matching service.
|
||
|
|
|
||
|
|
Options are the same as given in the `browser.find` function.

|
|
Emitted every time an existing service emmits a goodbye message.
