Toastflow

I recently needed a toast system for a Vue 3 app that was: • modern, • lightweight, • and didn’t fight my custom styling. I tried several Vue toast libraries and kept hitting the same issues: a lot of them were Vue 2–only or basically unmaintained, the styling was hard-wired instead of properly themeable, some were missing pretty basic options, and almost none gave me predictable behavior for things like duplicates, timers, or multiple stacks. So I ended up building my own: Toastflow (core engine) + vue-toastflow (Vue 3 renderer). What it is? • Headless toast engine + Vue 3 renderer • Toastflow keeps state in a tiny, framework-agnostic store (toastflow-core), and vue-toastflow is just a renderer on top with + a global toast helper. • CSS-first theming • The default look is driven by CSS variables (including per-type colors like --success-bg, --error-text, etc.). You can swap the design by editing one file or aligning it with your Tailwind/daisyUI setup. • Smooth stack animations • Enter/leave + move animations when items above/below are removed, for all positions (top-left, top-center, top-right, bottom-left, bottom-center, bottom-right). Implemented with TransitionGroup and overridable via animation config. • Typed API, works inside and outside components • You install the plugin once, then import toast from anywhere (components, composables, services, plain TS modules). Typed helpers: toast.show, toast.success, toast.error, toast.warning, toast.info, toast.loading, toast.update, toast.dismiss, toast.dismissAll, etc. • Deterministic behavior • The core handles duplicates, timers, pause-on-hover, close-on-click, maxVisible, stack order (newest/oldest), and clear-all in a predictable way. • Extras • Promise/async flows (toast.loading), optional HTML content with supportHtml, lifecycle hooks, events (toast.subscribeEvents), timestamps (showCreatedAt, createdAtFormatter), and a headless slot API if you want to render your own card.
