How to format the JSON object key/value pair

Question

I am new to nodejs, right now I am able to fetch the data from the database and display as REST API which is of key/value pair. My output looks like as shown below

Answer 1

The easy way to do it is to use underscore or lodash module to format it:

var _ = require('lodash');

var data = [{"id":"793","actionname":"test_bsc_interface","actionid":"100"}];
var result = _.map(data, function(o) {
  return {headers: _.keys(o), values : _.values(o)}
});
console.dir(result);

Output is:

[ 
  { 
    headers: [ 'id', 'actionname', 'actionid' ],
    values: [ '793', 'test_bsc_interface', '100' ] 
  } 
]

To get the result you want, just do result[0]

Note that I use _.map() instead of data[0] because this will work for the array (your array result from the query) that has more than 1 item.

Revised answer according to your comment (1 header line and all value lines in an array):

var _ = require('lodash');

var data = [
  { id: '714', actionname: 'test_bsc_interface', actionid: '100' },
  { id: '715', actionname: 'list_all_available_interfaces', actionid: '103' },
  { id: '716', actionname: 'check_tt', actionid: '101' }
];

var result;

if (_.size(data) > 0) {
  result = {
    headers: _.keys(data[0]),
    values: _.map(data, function(o) {
      return _.values(o);
    })
  };
}

console.dir(result);

and the output is:

{ 
  headers: [ 'id', 'actionname', 'actionid' ],
  values: [ 
    [ '714', 'test_bsc_interface', '100' ],
    [ '715', 'list_all_available_interfaces', '103' ],
    [ '716', 'check_tt', '101' ] 
  ] 
}
