NoFlo list components and metadata

noflo-list-components.js

var noflo = require('noflo');

var rootdir = './';
var loader = new noflo.ComponentLoader(rootdir);
loader.listComponents(function() {
        console.log(loader.components);

        Object.keys(loader.components).forEach(function(name) {
                loader.load(name, function(component) {
                        console.log(name);
                        console.log(component.description);

                        // for each port, should look at the .options key
                        // it has "description, type, datatype etc"
                        console.log(component.inPorts);
                        console.log(component.outPorts);
                });
        });
});

Returns the following from noflo-core

Graph

I gather I am noding wrong.

@nahoskins that is the printout of the components. Some time later (depending on how fast your harddrive is) you should get info per component

you seem to be running it from NoFlo itself, could be that the "Graph" there is causing a problem?

Here's an updated version. Apparently, the load() method's first parameter is returned as null... no idea why that changed but whatever:

var rootdir = './';
var loader = new noflo.ComponentLoader(rootdir);
loader.listComponents(function() {
  console.log(loader.components);

  Object.keys(loader.components).forEach(function(name) {
    loader.load(name, function(derp, component) {
      console.log(name);
      console.log(component.description);

      // for each port, should look at the .options key
      // it has "description, type, datatype etc"
      console.log(component.inPorts);
      console.log(component.outPorts);
    });
  });

});
