A simple json2csv converter + Express csv utility
npm install nice-json2csvnice-json2csv 
=============
A simple node.js tool that converts a Json object to a CSV output without requiring headers.
It can extend the Response object on Express.js to easily produce csv files available to be downloaded.
``shell`
npm install nice-json2csv
Include the library and use the convert function to get a csv string from your json object.
`js
var json2csv = require('nice-json2csv');
var myData = [{ "first_name": "John", "last_name": "Doe"}, { "first_name": "Jane", "last_name": "Doe"}, { "first_name": "Mick"}];
// all the json object
var csvContent = json2csv.convert(myData);
// just the 'first_name' column
var justFirstNames = json2csv.convert(myData, ["first_name"]);
// without the header row
var noHeader = json2csv.convert(myData, ["first_name"], true);
`
Include the library and decorate the Express object with app.use() as shown in the example after the express() initialisation. After that, res.csv() will be available.
Somewhere in your app.js, your middleware, or wherever you instantiate express.js
`js
var express = require('express');
var json2csv = require('nice-json2csv');
var app = express();
app.use(json2csv.expressDecorator);
app.get('/getCsv', function(req, res){
res.csv([{ "hello": "world" }], "myFile.csv");
});
app.listen(3000);
