Falcor Router should return the value from external API -


i new javascript frameworks , trying setup falcor router calling external api (for consider express api app + mango db, hosted @ 3000 port).

now, able use request package (commented out lines) , call express api app (which returns obj.rating = 4). unable send value falcor router instead of hard-coded value "5".

below falcor-router's server.js code:

app.use('/rating.json', falcorexpress.datasourceroute(function (req, res) {   return new router([     {       route: "rating",       get: function() {         var obj;         // request('http://localhost:3000/rating/101', function (error, response, body) {         //   obj = json.parse(body);         //   console.log('rating:', obj.rating); // obj.rating = 4         // });         return {path:["rating"], value:"5"};       }     }   ]); }));

the below code index.html:

<script> function showrating() {   var model = new falcor.model({source: new falcor.httpdatasource('http://localhost/rating.json') });   model.     get("rating").     then(function(response) {       document.getelementbyid('filmrating').innertext = json.stringify(response.json,null, 4);     }); } </script>

i tried @ global variable declaration, synchronize http request calls, promises, statements etc. nothing seemed work, missing out here - not sure what.

the router's get handler expects return value promise or observable resolves pathvalue. request against db work, return promise resolves pathvalue, e.g.

  return new router([     {       route: "rating",       get: function() {         return request('http://localhost:3000/rating/101', function (error, response, body) {            return { path: ["rating", value: json.parse(body).rating };          });       }     }   ]);

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
