Part of the CSV module, this project is a stringifier converting arrays or objects into a CSV text. It implements the Node.js stream.Transform API. It also provides a simple callback-based API for convenience. It is both extremely easy to use and powerful. It was first released in 2010 and is used against big data sets by a large community.

Usage

The module is built on the Node.js Stream API. For the sake of simplicity, a simple callback API is also provided. To give you a quick look, here's an example of the callback API:

var stringify = require('csv-stringify');

input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ];
stringify(input, function(err, output){
  output.should.eql('1,2,3,4\na,b,c,d\n');
});

Development

Tests are executed with mocha. To install it, run npm install followed by npm test. It will install mocha and its dependencies in your project "node_modules" directory and run the test suite. The tests run against the CoffeeScript source files.

To generate the JavaScript files, run npm run coffee.

The test suite is run online with Travis. See the Travis definition file to view the tested Node.js version.
