csv-stringify-as-promised

The csv-stringify is great, but it doesn't support promises! This module is a lightweight promise wrapper around it. The only prod dependency is csv-stringify.

Usage

``js
const stringify = require('csv-stringify-as-promised');
const assert = require('assert');

const input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ];

stringify(input).then((output) => {
assert.equal(output,
1,2,3,4
a,b,c,d
);
}).catch((err) => {
assert.fail(err);
});
`

You can pass any csv-stringify options by passing an object as the second argument.

`js
const stringify = require('csv-stringify-as-promised');
const assert = require('assert');
const options = { quotedString: true }
const input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ];

stringify(input, options).then((output) => {
assert.equal(output,
"1","2","3","4"
"a","b","c","d"
);
}).catch((err) => {
assert.fail(err);
});
`

$3

By default, this module uses Node's builtin Promise object, but if you prefer to use a different promise library, you can do so simply by overwriting the Promise property on the module.

`js
const stringify = require('csv-stringify-as-promised');
const bluebird = require('bluebird');

stringify.Promise = bluebird;

const input = [ [ '1', '2', '3', '4' ], [ 'a', 'b', 'c', 'd' ] ];

stringify(input).then((output) => {
// uses bluebird instead of Promise
}).catch((err) => {
// handle error
});
`

$3

By default, this module uses csv-stringify library, but if you prefer to use a different CSV library, you can do so simply by overwriting the csvStringify property on the module.

`js
const stringify = require('csv-stringify-as-promised');

stringify.csvStringify = yourCustomLibrary;
`

Requirements

This module requires NodeJS 8 or greater
