Express CSV provides response CSV easily to Express.

Installation

npm:

$ npm install express-csv

Usage

Example:

var express = require('express')
  , csv = require('express-csv')
  , app = module.exports = express.createServer();

app.get('/', function(req, res) {
  res.csv([
    ["a", "b", "c"]
  , ["d", "e", "f"]
  ]);
});

app.listen(3000);

Response:

$ curl --verbose http://127.0.0.1:3000/
* About to connect() to 127.0.0.1 port 3000 (#0)
*   Trying 127.0.0.1... connected

Alternatively, you can also pass an array of objects to be serialized, in which case the object's properties will be iterated over. E.g.:

res.csv([ { name: "joe", id: 1 }]
//=> "joe", 1
