svelte-notifications-stack v1.1.3

#svelte-notifications-stack

Svelte component for displaying notifications in the application.

##Usage:

To use notifications-stack, you need to wrap a component that will be used to display notifications. For example, it can be a component that sends data to the server and receives a response, and depending on the response, we can show a notification. Or, you can wrap the entire application and use the notification wherever you need it.

####Default notifications:

Let's say this is your application - App.svelte:

<script>
  import Notifications from 'svelte-notifications-stack';
  import Header from './Header'
  import Pages from './Pages'
  import Footer from './Footer'
</script>
<Notifications maxCount={3}>
  <div>
    <Header />
    <Pages />
    <Footer />
  </div>
</Notifications>

And now we want to use basic notifications in our application in the Pages component - Pages.svelte:

<script>
  import {getContext} from 'svelte';
  import {CONTEXT_NAME} from 'svelte-notifications-stack';


  const {add, types} = getContext(CONTEXT_NAME);
  const handleAddDefaultNotification = (type) => {
    add({message: 'Message', type})
  };
</script>

<div>
  Main page
  <button on:click={()=>handleAddDefaultNotification(types.INFO)}>
    Show info notification
  </button>
</div>

In this example, we take the notification context and use the add method to add the notification:

import {CONTEXT_NAME} from 'svelte-notifications-stack';
const {add, types} = getContext(CONTEXT_NAME);
const handleAddDefaultNotification = (type) => {
  add({message: 'Message', type})
};

####Custom notifications:

Let's take the same application code as an example - App.svelte:

<script>
  import Notifications from 'svelte-notifications-stack';
  import Header from './Header'
  import Pages from './Pages'
  import Footer from './Footer'
</script>
<Notifications maxCount={3}>
  <div>
    <Header />
    <Pages />
    <Footer />
  </div>
</Notifications>

And let's create our custom notification:

<script>
  import {getContext} from 'svelte';
  import {CONTEXT_NAME} from 'svelte-notifications-stack';
  import CustomComponent from './CustomComponent';

  const {add} = getContext(CONTEXT_NAME);

  const handleAddCustomNotification = () => {
    add({
      component: CustomComponent, 
      componentProps: ({id})=>({
        id, 
        text: 'Custom text'
      })
    })
  };
</script>
<div>
  Main page
  <button on:click={handleAddCustomNotification}>
    Show custom notification
  </button>
</div>

And in our CustomComponent we receive props witch we passed in componentProps callback:

<script>
  import {getContext} from "svelte";
  import {CONTEXT_NAME} from "svelte-notifications-stack";

  export let id
  export let text
  const {close} = getContext(CONTEXT_NAME);
</script>

<div>
    <div>{text}</div>
    <div on:click={()=>close(id)}>close</div>
</div>

As you can see, we get id, text witch we passed in componentProps callback, and now we can close custom notification with close method from the context on:click={()=>close(id)}
