# Unofficial Stripe.JS wrapper for Opal

`stripe-opal` provides credit card payment capabilities to opal by wrapping Stripe.js and providing a nice ruby syntax for dealing with card payments.

## Note

This is an unofficial Gem and I don't work for Stripe. The gem is maintained, but not officially supported or endorsed by Stripe.

## Getting Started

### Usage

Add this to `app/main/config/dependencies.rb` for your **Volt Project**:

```ruby
javascript_file "https://js.stripe.com/v2/"
```

OR, if you are writing a **static app that does not use Volt, but uses Opal**:

```html
<script type="text/javascript" src="https://js.stripe.com/v2/"></script>
```
THEN

Make this HTML form...

```html
<form action="" method="POST" id="payment-form">
  <span class="payment-errors"></span>

  <div class="form-row">
    <label>
      <span>Card Number</span>
      <input type="text" size="20" data-stripe="number"/>
    </label>
  </div>

  <div class="form-row">
    <label>
      <span>CVC</span>
      <input type="text" size="4" data-stripe="cvc"/>
    </label>
  </div>

  <div class="form-row">
    <label>
      <span>Expiration (MM/YYYY)</span>
      <input type="text" size="2" data-stripe="exp-month"/>
    </label>
    <span> / </span>
    <input type="text" size="4" data-stripe="exp-year"/>
  </div>

  <button type="submit">Submit Payment</button>
</form>
```

And run payments like this:

```ruby

StripeOpal::Card
  .get_token('#payment-form') # Notice the ID on the form above?
  .then { |token| "Pass the `token.id` to a Volt::Task or AJAX call" }
  .fail { |error|  "Tell the user they put bad info in." }

```

If you are developing a [Volt Framework](http://www.voltframework.com) app, it's best to put the code above in a controller method

```
def pay_from_controller
  StripeOpal::Card
    .get_token('#payment-form') # Notice the ID on the form above?
    .then { |token| "Pass the `token.id` to a Volt::Task or AJAX call" }
    .fail { |error|  "Tell the user they put bad info in." }
end
```

and add `e-submit="pay_from_controller"` to the `<form>` tag.

## Installation

Install stripe-opal from RubyGems:

```
$ gem install stripe-opal
```

Or include it in your Gemfile for Bundler:

```ruby
gem 'stripe-opal'
```
