|
|
This package is a stringifier converting records into a CSV text and
|
||
|
|
implementing the Node.js [`stream.Transform`
|
||
|
|
API](https://nodejs.org/api/stream.html). It also provides the easier
|
||
|
|
synchronous and callback-based APIs for conveniency. It is both extremely easy
|
||
|
|
to use and powerful. It was first released in 2010 and is tested 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:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
const stringify = require('csv-stringify')
|
||
|
|
const assert = require('assert')
|
||
|
|
// import stringify from 'csv-stringify'
|
||
|
|
// import assert from 'assert/strict'
|
||
|
|
|
||
|
|
const input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ]
|
||
|
|
stringify(input, function(err, output) {
|
||
|
|
const expected = '1,2,3,4\na,b,c,d\n'
|
||
|
|
assert.strictEqual(output, expected, `output.should.eql ${expected}`)
|
||
|
|
console.log("Passed.", output)
|
||
|
|
})
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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 build`.
|
||
|
|
|
||
|
|
The test suite is run online with
|
||
|
|
[Travis](https://travis-ci.org/#!/adaltas/node-csv-stringify). See the [Travis
|
||
|
|
definition
|
||
|
|
file](https://github.com/adaltas/node-csv-stringify/blob/master/.travis.yml) to
|
||
|
|
view the tested Node.js version.
