## How To

Simple Card is a plug and play module, `import`, `require`, or even `script` tag it in

Standard JS
```js
import { validate } from 'simple-card';

validate(data);
```

CommonJS
```js
const { validate } = require('simple-card');

validate(data);
```

Browser

<script>
	simpleCard.validate(data);
</script>
```

## Documentation

You can find most of the documentation for simple card here: https://www.dusty.codes/simple-card

## Modular

Simple Card is completely modular which means each piece of functionality can be imported by itself directly, or with destructuring.

Example:

```js
import validate from 'simple-card/validate'
import num from 'simple-card/number'
import cvn from 'simple-card/cvn'
import expired from 'simple-card/expired'
import matches from 'simple-card/matches'

// Or with destructuring

import { validate, number, cvn, matches, expired } from 'simple-card'
```

You can then call each function individually.

This also works with `commonjs` you just need to point directly to the file you want

**NOTE:** In order to use `validate` you need to pass a full card object to it like so:

```js
{
  number: '4111 1111 1111 1111',
  cvn: '342',
  date: '12/20'
}
```
