## Installation

```
npm i notyf
```

## Usage

This section explains the base case using the minified bundle. See the [quick recipes](recipes/README.md) section for instructions to plug Notyf into Angular, React, Aurelia, Vue, or Svelte.

Add the css and js files to your main document:

```html
<html>
  <head>

  </body>
</html>
```

### Basic

```javascript
// Create an instance of Notyf
var notyf = new Notyf();

// Display an error notification
notyf.error('You must fill out the form before moving forward');

// Display a success notification
notyf.success('Your changes have been successfully saved!');
```

### With module bundlers

Notyf ships with an ES6 bundle referenced from the `module` key of its package.json. This is the file that module bundlers like Webpack will use when using the package. `Notyf` is exported as a class under the `notyf` namespace. Typings are also available.

```javascript
import { Notyf } from 'notyf';
import 'notyf/notyf.min.css'; // for React, Vue and Svelte

// Create an instance of Notyf
const notyf = new Notyf();

// Display an error notification 
notyf.error('Please fill out the form');
```

## API

You can set some options when creating a Notyf instance.

### `new Notyf(options: INotyfOptions)`

Param | Type | Default | Details
------------ | ------------- | ------------- | -------------
duration | `number` | 2000 | Number of miliseconds before hiding the notification. Use `0` for infinite duration.
ripple | `boolean` | true | Whether to show the notification with a ripple effect
position | [`INotyfPosition`](#inotyfposition) | `{x:'right',y:'bottom'}` | Viewport location where notifications are rendered
dismissible | `boolean` | false | Whether to allow users to dismiss the notification with a button
types | [`INotyfNotificationOptions[]`](#inotyfnotificationoptions) | Success and error toasts | Array with individual configurations for each type of toast

### `dismiss(notification: NotyfNotification)`

Dismiss a specific notification.

```javascript
const notyf = new Notyf();
const notification = notyf.success('Address updated');
notyf.dismiss(notification);
```

### `dismissAll()`

Dismiss all the active notifications.

```javascript
const notyf = new Notyf();
notyf.success('Address updated');
notyf.error('Please fill out the form');
notyf.dismissAll();
```

## Events

Every individual notification emits events. You can register listeners using the `on` method.

### `'click'`

Triggers when the notification is clicked

```javascript
const notyf = new Notyf();
const notification = notyf.success('Address updated. Click here to continue');
notification.on('click', ({target, event}) => {
  // target: the notification being clicked
  // event: the mouseevent
  window.location.href = '/';
});
```

### `'dismiss'`

Triggers when the notification is **manually** (not programatically) dismissed.

```javascript
const notyf = new Notyf();
notyf
  .error({
    message: 'There has been an error. Dismiss to retry.',
    dismissible: true
  })
  .on('dismiss', ({target, event}) => foobar.retry());
```

## Interfaces

### INotyfPosition

Viewport location where notifications are rendered.

Param | Type | Details
------------ | ------------- | -------------
x | `left \| center \| right` | x-position
y | `top \| center \| bottom` | y-position

### INotyfNotificationOptions

Configuration interface for each individual toast.

Param | Type  | Details
------------ | ------------- | -------------
type | `string` | Notification type for which this configuration will be applied
className | `string` | Custom class name to be set in the toast wrapper element
duration | `number` | 2000 | Number of miliseconds before hiding the notification
icon | `string` [`INotyfIcon`](#inotyficon) `false` | Either a string with HTML markup, an object with the properties of the icon, or 'false' to hide the icon
background | `string` | Background color of the toast
message | `string` | Message to be rendered inside of the toast. Becomes the default message when used in the global config.
ripple | `boolean` | Whether or not to render the ripple at revealing
dismissible | `boolean` | Whether to allow users to dismiss the notification with a button

### INotyfIcon

Icon configuration

Param | Type | Details
------------ | ------------- | -------------
className | `string` | Custom class name to be set in the icon element
tagName | `string` | HTML5 tag used to render the icon
text | `string` | Inner text rendered within the icon (useful when using [ligature icons](https://css-tricks.com/ligature-icons/))
color | `string` | Icon color. It must be a valid CSS color value. Defaults to background color.

## Examples

### Global configuration

The following example configures Notyf with the following settings:
- 1s duration
- Render notifications in the top-right corner
- New custom notification called 'warning' with a [ligature material icon](https://google.github.io/material-design-icons/)
- Error notification with custom duration, color and dismiss button

```javascript
const notyf = new Notyf({
  duration: 1000,
  position: {
    x: 'right',
    y: 'top',
  },
  types: [
    {
      type: 'warning',
      background: 'orange',
      icon: {
        className: 'material-icons',
        tagName: 'i',
        text: 'warning'
      }
    },
    {
      type: 'error',
      background: 'indianred',
      duration: 2000,
      dismissible: true
    }
  ]
});
```

### Custom toast type

Register a new toast type and use it by referencing its type name:

```javascript
const notyf = new Notyf({
  types: [
    {
      type: 'info',
      background: 'blue',
      icon: false
    }
  ]
});

notyf.open({
  type: 'info',
  message: 'Send us <b>an email</b> to get support'
});
```

**Warning:** Notyf doesn't sanitize the content when rendering your message. To avoid [injection attacks](https://github.com/caroso1222/notyf/issues/72), you should either sanitize your HTML messages or make sure you don't render user generated content on the notifications.

### Default types with custom configurations

The default types are 'success' and 'error'. You can use them simply by passing a message as its argument, or you can pass a settings object in case you want to modify its behaviour.

```javascript
const notyf = new Notyf();

notyf.error({
  message: 'Accept the terms before moving forward',
  duration: 9000,
  icon: false
})
```

## Recipes

Notyf is well supported in all of the modern frameworks such as Angular, React, Aurelia, Vue, or Svelte. [Check out the recipes](recipes/README.md) and learn how to integrate the library to your application.
