Creating a JSON Array in node js

Question

I need to create in my server written in node js a JSON string to be sent to the client when this request it  The problem is that this JSON depends on the available data in the server  thus  the size of the JSON array is not the same always  I  ve trying whole day but although I feel to be close I still dont get it   An example query follows   json   players                  name   Messi    goals  8                             name   Ronaldo    goals  22                 name   Costa    goals  20                 name   Neymar    goals  13                 name   Arabi    goals  6                 name   Bale    goals  3                 name   Toquero    goals  0       I would send it to the server by   res contentType  application json    res send json     The JSON array that I want create it depends on a hash called  goals  where a player name is the key and a number of goals the value  Thus  if there are only 3 players  the JSON Array only should have this size   I  ve been trying to create the JSON array online like this   result      for i in goals       result   result     name     i      goals     goals i            result  result substring 0  result length - 1    res contentType  application json    res send     players     result       However  the client only receives a json of size 1  Object  jugadores  Array 1     jugadores  Array 1  0     nombre Messi  goles 8    nombre Ronaldo  goles 16    nombre Costa  goles 10    nombre Toquero  goles 0    nombre Arabi  goles 2    nombre Bale  goles 10    nombre Neymar  goles 8   length  1  Thanks in advance  Im really struggling with this     Edit  Im trying now with stringy doing this  but no luck  What do I do wrong   result   players     for i in goals       result  result     name     i      goals     goals i             result  result substring 0  resultado length - 1     result  result        res contentType  application json    myJSONstring   JSON stringify resultado   res send myJSONstring     Goals hash is filled using GET   app get   player  id   function  req  res       res contentType  application json    res send    goals     goals req params id

You don t have JSON  You have a JavaScript data structure consisting of objects  an array  some strings and some numbers   Use JSON stringify object  to turn it into  a string of  JSON text

Build up a JavaScript data structure with the required information  then turn it into the json string at the end   Based on what I think you re doing  try something like this   var result       for  var name in goals      if  goals hasOwnProperty name         result push  name  name  goals  goals name            res contentType  application json    res send JSON stringify result      or something along those lines
