Wrapper around cluster module to simplify multi-process work
SPAM is a module for simple node process management, and wraps the cluster module.
$ npm install spam
To create some processes, using the spawn method. This takes the following parameters:
var spam = require'spam';// to create 4 processes using the myscript.js scriptspamspawn'./myscript.js' number: 4 timeout: 60000 strategy: 'parallel'// callback occurs when all processes have declared they are working// or a timeout occursif errconsole.log'oops';;
If you want to log what's going on in SPAM
spamon'log'// do some loggingconsole.log'SPAM: ' + message;;
If you want to gracefully restart all the processes, by starting a new worker before killing the old worker, do this with the restart method.
// graceful restart of all the processesspamrestart strategy: 'series'if errconsole.log'oops';;
NOTE: The scripts that are run, need to emit a 'ready' message when they have initialized. If they do not do this, then SPAM will assume they've not started and time them out.
var signal = require'spam'signal;signalready;
To run the npm unit tests, install development dependencies and run tests with 'npm test' or 'make'.
$ cd nlf$ npm install$ npm test
