Usage

npm i -D @beyonk/svelte-notifications

<NotificationDisplay />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

function someFunction () {
  notifier.success('Notifications work!')
}
</script>

Notification types

You can call multiple types of notification:

const options = {
  timeout: 3000, // milliseconds
  persist: false, // automatic timeout (ignores above)
  showProgess: true, // Show (or Hide) the progress bar
  icon: null // Add svelte component to render an icon
}

notifier.show('danger', message, options)
notifier.danger(message, options),
notifier.warning(message, options),
notifier.info(message, options),
notifier.success(message, options)

Persisting across apps

Your notifications can persist across multiple apps / page reloads, as long as they use this library. This is useful for a scenario where you show a notification and then redirect the browser to a different application, or trigger a full reload of the page.

This is completely automatic and uses session storage.

To ensure that notifications don't persist across apps where they should not, set the sessionKey attribute to something unique to each app.

<NotificationDisplay sessionKey="foo" />

Notification themes

You can customise the themes:

<NotificationDisplay {themes} />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

let themes = { // These are the defaults
  danger: '#bb2124',
  success: '#22bb33',
  warning: '#f0ad4e',
  info: '#5bc0de',
  default: '#aaaaaa' // relates to simply '.show()'
}

function someFunction () {
  notifier.success('Notifications work!')
}
</script>

Custom types

<NotificationDisplay {themes} />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

let themes = {
  myColour: '#ff00bb'
}

function someFunction () {
  notifier.send('myColour', 'Notifications work!')
}
</script>

Timeouts

You can set a default timeout:

<NotificationDisplay {timeout} />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

let timeout = 3000 // The default

function someFunction () {
  notifier.success('Notifications work!')
}
</script>

Custom timeout:

You can set a timeout per message

<NotificationDisplay />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

function someFunction () {
  notifier.success('Notifications work!', { timeout: 5000 }) // built in theme
  notifier.send('custom-theme', 'Notifications work!', { timeout: 5000 }) // custom theme
}
</script>

Show Progress:

You can show or hide the progress bar per message

<NotificationDisplay />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

function someFunction () {
  notifier.success('Notifications work!', { showProgress: false }) // built in theme
  notifier.send('custom-theme', 'Notifications work!', { showProgress: true }) // custom theme
}
</script>

Persist

You can make a message persist and never timeout, having a close button that the user can click to remove it.

<NotificationDisplay />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'

function someFunction () {
  notifier.success('Notifications work!', { persist: true }) // built in theme
  notifier.send('custom-theme', 'Notifications work!', { persist: true }) // custom theme
}
</script>

Icons

You can include custom svelte components to render icons (or anything).

<NotificationDisplay />

<button on:click={someFunction}>Show message</button>

<script>
import { NotificationDisplay, notifier } from '@beyonk/svelte-notifications'
impoer Icon from 'somewhere/Icon.svelte'

function someFunction () {
  notifier.success('Notifications work!', { icon: Icon })
}
</script>

// Icon.svelte

<svg width="1em" height="1em" viewBox="0 0 36 36">
  <path
    fill="currentColor"
    d="M18 34a16 16 0 1 1 16-16a16 16 0 0 1-16 16Zm0-30a14 14 0 1 0 14 14A14 14 0 0 0 18 4Z"
  </path>
</svg>
