Is Apple just doing a clumsy “hard-sell” trying to push its latest “cool” technology?No, there’s a good reason for the Bonjour menu in Safari.Many of today’s network devices, like printers, network cameras, and home gateways,are configured and managed using a web browser.

Supported a function-based filtering mechanism in the discover() method.Fixed a bug that some event listeners did not be removed when the discovery process is finished.In this version, all available IPv4 network interfaces are joined to a multicast group, so that all devices in the local network are sure to be discovered. Added the key and type parameters to the discover() method.Added the rdata_buffer property in the DnsSdPacket object.Fix of address already in use on udp.addMembership method (thanks to v0.4.0 ().Catch dropMembership error (thanks to v0.4.1 ().See the section " References" for more details. You can parse the binary data using this property. Some devices set a binary data to each value. Each value in the rdata_buffer is a Buffer object. Note that the rdata_buffer property is added only if the type is "TXT". If the values are not obtained from the response packet, they will be set to null. Note that the values of properties other than the address are not necessarily set in this object. Each device information in the list contains the properties as follows: PropertyĪn object representing the response packet The discover() method will pass a information list of the found devices to the callback function. You can evaluate the device information and limit to devices you want. discover ( ) Īs you can see from the code above, an object representing a found device is passed to the function. If you want to discover all services in the local netowrk, you can set the name property to _services._dns-sd._udp.local'. If a function is specified to the filter, this method discovers only devices for which the function returns true. If a string is specified to the filter, this method discovers only devices which the specified string is found in the fqdn, address, modelName or familyName. If true, this method returns immediately after a device was found ignoring the value of the wait. See the description below for details.ĭuration of monitoring (sec). This property indicates how to fold multiple DNS-SD query responses. This value must be "address" (default) or "fqdn". Service name.(e.g., "_googlecast._tcp.local") This method takes a hash object containing the properties as follows: Property The discover() method discovers devices supporting the service specified to this method in the local network. The DnsSd object has methods as described in sections below. In the code snippet above, the variable DnsSd is a DnsSd object. In order to use the node-dns-sd, you have to load the node-dns-sd module as follows:Ĭonst DnsSd = require ( 'node-dns-sd' ) The object above is a DnsSdPacket object which represents a mDNS/DNS-SD response packet.
