React + Sonner for toast notifications.

StylingTailwindCSS 4

Why

Stackable, animated, promise-aware toasts. JavaScript is used by 62% of developers per the Stack Overflow 2024 survey, and React holds 40% framework market share (State of JS 2024).

Vite replaced Webpack as the default bundler, cutting dev server startup from 30s to <1s.

When

Use for notifications. Avoid for blocking dialogs.

How

1. npm i sonner 2. Add <Toaster /> to root 3. Call toast() anywhere 4. Customize styles 5. Add environment configuration — cp .env.example .env && edit values 6. Run tests — npm test or pnpm test to verify setup 7. Deploy — git push to trigger CI/CD or manual deploy

Example

import { toast } from 'sonner' toast.success('Saved!') toast.promise(saveData(), { loading: 'Saving...', success: 'Done!', error: 'Failed' })

Common Problems

  • ⚠Toast stacking — set richColors and position
  • ⚠Promise toast — ensure promise resolves/rejects
  • ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

  • ✓Use toast.custom for custom UI
  • ✓Set duration based on message length
  • ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

FAQ

What is React Toast SPA and what projects is it for?

React + Sonner for toast notifications. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.

How do I spin up a working demo with React Toast SPA in 10 minutes?

Two steps: (1) npm i sonner; (2) Add <Toaster /> to root. Get the local dev server running, then wire one real data source to verify the end-to-end loop.

What is the most common pitfall with React Toast SPA and how do I avoid it?

The most common pitfall is: Toast stacking — set richColors and position. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.

What are the best practices for React Toast SPA?

Best practices for React Toast SPA include: Use toast.custom for custom UI; Set duration based on message length; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use toast.custom for custom UI" — should be set up at project init to avoid costly rework later.

When should I NOT choose React Toast SPA?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). React Toast SPA shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
