    sproc

    This module is useful when you want to spawn a single daemon and be able to connect to it from other processes.

    workflow:

    • attempt to connect to daemon
    • if connection fails, spawn daemon (return to first step)
    • upon connection, callback with a stream

    Install

    npm install sproc

    Use

    daemon.js

     
    // echo daemon
     
    var clients = 0;
     
    module.exports = function(options, stream) {
      clients++;
     
      stream.write(clients + ' clients');
      stream.on('end', function() {
        clients--;
        if (clients > 0) {
          stream.write(clients + ' clients');
        } else {
          process.exit();
        }
      });
     
      stream.pipe(stream, { end: false });
    };
     

    main.js

     
    var sproc = require('sproc');
     
    sproc({
      script: './daemon',
      port: 4499,
    }, function(proc) {
      proc.stream.write('hello');
      stream.on('data', console.log); // outputs hello
    });
     

    options

    • port - port to use for listening/connecting (default: 4499)
    • keepProcessReference - do not detatch from the daemon (default: false)
    • log - a function (optional)
