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