svelte-sonner
An opinionated toast notification component for Svelte applications, ported from Sonner.
What is svelte-sonner?
svelte-sonner is a toast notification library specifically designed for Svelte applications. It provides a flexible and customizable way to display temporary messages, alerts, and feedback to users with minimal setup, enhancing user experience through a simple API.
Svelte developers who need to implement toast notifications in their applications, particularly those using Tailwind CSS or requiring extensive customization options like different toast types, themes, and programmatic control.
Developers choose svelte-sonner for its seamless integration with Svelte, extensive customization capabilities including Tailwind CSS support, and a feature-rich API that includes multiple toast types, programmatic updates, and advanced functionality like promise handling and custom components.
Overview
An opinionated toast component for Svelte. A port of @emilkowalski's sonner.
Use Cases
Best For
- Adding toast notifications to Svelte applications with minimal boilerplate code.
- Implementing customizable toast types such as success, error, warning, info, action, and promise-based notifications.
- Styling toast notifications with Tailwind CSS using the unstyled mode and class-based customization.
- Managing toasts programmatically with features like updating, dismissing, and tracking via the useSonner hook.
- Displaying custom components as toasts while maintaining default functionality through the headless or custom component options.
- Handling asynchronous operations with promise toasts that automatically update based on resolution or failure.
Not Ideal For
- Projects built with frameworks other than Svelte, such as React or Vue, due to its Svelte-specific implementation.
- Applications requiring out-of-the-box accessibility compliance (e.g., screen reader support) without additional customization, as the README does not mention accessibility features.
- Teams seeking a minimal, zero-dependency toast solution with a tiny bundle size, since svelte-sonner includes advanced features that add overhead.
- Use cases needing server-side rendered notifications that work without JavaScript, as toasts are client-side components.
Pros & Cons
Pros
Supports default, success, info, warning, error, action, promise, and custom components, as detailed in the Types section, enabling versatile user feedback.
Offers unstyled mode and class-based styling for seamless Tailwind CSS usage, explicitly shown in the Tailwind CSS section with examples for per-toast customization.
Allows updating, dismissing, and tracking toasts via API calls and the useSonner hook, enabling dynamic management as demonstrated in the Programmatically remove toast and useSonner sections.
Provides themes, positions, expandability, rich colors, and custom icons through snippets, as evidenced in the Customization section for flexible UI adaptation.
Cons
The README does not mention built-in accessibility features like ARIA labels or keyboard navigation, requiring developers to implement them manually, which can be a oversight for inclusive design.
As a Svelte-specific library ported from Sonner, it cannot be used in projects with other frameworks, limiting portability and creating vendor lock-in for Svelte-only ecosystems.
Custom styling, especially with Tailwind, requires understanding multiple class properties and snippets, which can be overwhelming for simple use cases compared to drop-in styled solutions.
