# nvpqs

[NVP](https://developer.paypal.com/docs/classic/api/NVPAPIOverview/#id09C2F0D0DX4) parser. Like [querystring](https://nodejs.org/api/querystring.html), but for pairs where the name encodes primitive types, objects or arrays.

### `parse(string, [del], [sep], [eq])`

Deserialize a NVP query string to an object. Optionally  override the default delimiter (`.`), separator (`&`) and assignment (`=`) characters.

#### Example

```js
const Nvpqs = require('nvpqs');

Nvpqs.parse('a=b&c.d=e&f.0=g'); // { a: 'b', c: { d: 'e' }, f: ['g'] }
```

### `stringify(object, [del], [sep], [eq])`

Serialize an object to a NVP query string. Optionally override the default delimiter (`.`), separator (`&`) and assignment (`=`) characters.

#### Example

```js
const Nvpqs = require('nvpqs');

Nvpqs.stringify({ a: 'b', c: { d: 'e' }, f: ['g'] }); // 'a=b&c.d=e&f.0=g'
```
