ataraxia-local v0.12.0

ataraxia-local

Machine-local transport for Ataraxia. This transport connects together instances on the same machine via a Unix socket.

Usage

npm install --save ataraxia-local

To use only the machine-local transport:

import { Network, AnonymousAuth } from 'ataraxia';
import { MachineLocalTransport } from 'ataraxia-local';

// Setup a network
const net = new Network({
  name: 'name-of-your-app-or-network',

  transports: [
    new MachineLocalTransport()
  ]
});

await net.join();

onLeader can be used to start a secondary network transport that will handle connections to other machines:

import { Network, AnonymousAuth } from 'ataraxia';
import { TCPTransport, TCPPeerMDNSDiscovery } from 'ataraxia-tcp';
import { MachineLocalTransport } from 'ataraxia-local';

// Setup a network
const net = new Network({
  name: 'name-of-your-app-or-network',
});

net.addTransport(new MachineLocalTransport({
  onLeader: () => {
    /*
    * The leader event is emitted when this instance becomes the leader
    * of the machine-local network. This instance will now handle
    * connections to other machines in the network.
    */
    net.addTransport(new TCPTransport({
      discovery: new TCPPeerMDNSDiscovery(),

      authentication: [
        new AnonymousAuth()
      ]
    }));
  }
});

await net.join();

API

• new MachineLocalTransport(options)

  Create a new instance of the transport.

  • options
    • path?: string, path of the local socket. If not specified the transport defaults to creating a socket in the temporary directory of the system using the name of the network.
    • onLeader?: () => void, function that will be run if this instance becomes the leader of the local network.

• onLeader(callback: () => void)

  Event emitted if this transport becomes the leader of the local network.
