zap

zap is a library to display simple yet customizable notifications in Svelte.
You can stylize text with a simple syntax, add buttons to make the notifications interactable and add callbacks for some events during the life of a notification.

You can find a live demo here: https://zap.nikurasu.org/
You can also run the demo locally by installing the dependencies and then run pnpm run dev.

Installation

pnpm add @glagan/zap

How to use

zap needs a container to display the notification, you need to have the component ZapContainer included somewhere, e.g in your index.

<script>
    import { ZapContainer } from '@glagan/zap';
</script>

<ZapContainer />

Once the container is available, you can display notifications by interacting with the zap store.

<script>
    import { zap } from '@glagan/zap';

    zap.success({ title: 'zap' });
</script>

Templates

There is 5 default templates: success, error, info, warning and message.

zap.success({
    title: 'Title', // The title of the notification
    image: 'url', // Optional image displayed inside the notification
    imageAlt: 'image', // Optional image alt text
    message: 'Content', // Content of the notification
    // Optional list of buttons to interact with the notification
    buttons: [{
        value: 'Confirm', // The text inside the button
        type: 'success', // The type of the button, same as for the notifications
        onClick: (notification) => {
            // The onClick function receive the notification from which the button has been clicked
            // You can call notification.remove(), notification.close() or notification.closeFadeout()
            // if you wish to remove the notification by clicking on  the buttons
        }
    }],
    classes: ['class'] // Optional additional CSS classes applied to the notification
}, options); // See the the list of options below

All keys in the first parameter are optional, but at least one of title, image or message is required.

You can still update the content and state of any notification after it's been created by updating the values in the Notification object that was returned by zap:

const notification = zap.success({ title: 'zap' });
notification.title = 'ZAP';
notification.repaint(); // A repaint() call is necessary (for now ?)

Options

There are a few options that you can set by using zapOptions.setDefault(options) or more specifically for a single notification on the third parameter.

Events

There are four events during the process of displaying every notification:

• onCreate(notification) called when the notification node is created but empty.
• onDisplay(notification) called when the notification node is appended to its wrapper.
• onDeath(notification) called when the duration timer has expired.
  • If you set the onDeath function you take ownership of the notification removal and you need to call notification.close() or notification.destroy() manually, or else the notification won't disappear.
• onDisplay(notification) after the notification has been closed.

Animations

You can customize the insert and remove animations of a notification by giving a value to the insertAnimation (or removeAnimation) option. The option take an object like the following:

{
    name: "default-insert", // See the list below
    duration: 250 // In ms
}

The insert animations are: insert-[left|top|right|bottom], fadein, scalein and rotatein.

By default the animation is default-insert which is a special value that automatically choose the corresponding insert animation after the notification position.

The remove animations are: fadeout, scaleout and rotateout.

You can add your own animations by adding them in your own CSS files and setting the name of the animation in the parameter.

minimark

zap uses minimark to render the text inside the notifications.
You can check the minimark documentation to see how to add or write tags.

Migration

If you were using SimpleNotification, a few changes have been made:

• closeAnimated is replacing close and is now the default and the old close has been renamed destroy
• The setters have been removed, you can now directly use assignments in callbacks (e.g notification.title = 'Title' intead of notification.setTitle('Title'))
• The text renderer is now an external dependency and the tags definition (not the syntax) has changed, see minimark documentation for the new definition

This package is a port of SimpleNotification for Svelte. If you want to use the same notifications but outside of Svelte or any other frameworks, use Simple Notification.
