SimpleToasts

A zero-dependency, PrimeNG-inspired toast notification library for Roblox.

Collapsed pile (hover to expand)	Expanded pile

Features

• 🎨 Five severities : success, info, warn, error, secondary, each with its own colours, icon, and sound (optional); fully overridable per toast via customTheme.
• 📍 Six positions : top-left, top-center, top-right, bottom-left, bottom-center, bottom-right.
• 🥞 Stacked piles (Sonner-style, on by default) : newest toast in front, older edges peeking behind; hover (desktop) or tap (mobile) expands the pile and pauses every timer in it.
• ⏱️ Auto-dismiss with life, sticky toasts, close button, and pause-on-hover.
• 🎬 Smooth animations : slide-in/out from the nearest screen edge + fade, with tweenable neighbour reflow; duration and easing are configurable.
• 🔊 Sounds (opt-in) : per-severity defaults, per-toast override (sound, silent, volume), global toggle.
• 🌐 Server → client bridge : fire toasts from the server with Toast.notify / Toast.notifyAll (display-only; the client never trusts remote data for anything else).
• 🧱 Zero dependencies : native Luau instances only (CanvasGroup, TweenService, …). No Fusion, Roact, or React-lua. Fully --!strict typed.

Installation

Wally

[dependencies]
SimpleToasts = "rvila94/simpletoasts@0.1.0"

Then run wally install and require it from your Packages folder.

Standalone model

Build a .rbxm with Rojo and drop it anywhere your scripts can reach (e.g. ReplicatedStorage):

rojo build default.project.json -o SimpleToasts.rbxm

Quick start

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Toast = require(ReplicatedStorage.Packages.SimpleToasts)

-- Convenience shortcuts: (summary, detail?, options?)
Toast.success("Saved!", "Your progress has been saved.")
Toast.info("Heads up")
Toast.warn("Storage almost full", nil, { position = "bottom-center" })
Toast.error("Something went wrong", "Please try again later.", { life = 8000 })
Toast.secondary("Background task finished")

Full message form

Toast.add({
	severity = "success",   -- "success" | "info" | "warn" | "error" | "secondary"
	summary  = "Title",
	detail   = "Optional body text",
	life     = 4000,        -- ms before auto-dismiss (default: 3000)
	sticky   = false,       -- true = never auto-dismiss
	closable = true,        -- show the close button (default: true)
	position = "top-right", -- one of the six positions (default: "top-right")

	-- Appearance override (all colours/icon/sound of the severity theme):
	customTheme = {
		backgroundColor = Color3.fromRGB(249, 219, 159),
		accentColor = Color3.fromRGB(209, 152, 38),
		detailTextColor = Color3.fromRGB(30, 30, 30), -- omit for the default dark grey
		iconAssetId = "rbxassetid://...", -- omit to show no icon
	},

	-- Sound (all optional; sounds are off by default, see configure below):
	sound  = "rbxassetid://...", -- plays even when soundEnabled = false
	silent = false,              -- true = suppress sound for this toast
	volume = 0.8,                -- 0-1, overrides defaultVolume
})

-- Several at once:
Toast.addAll({ message1, message2 })

-- Remove every visible toast (optionally only one position):
Toast.clear()
Toast.clear("bottom-right")

From the server

-- Fire a toast to one player, or to everyone:
Toast.notify(player, { severity = "success", summary = "Welcome!" })
Toast.notifyAll({ severity = "info", summary = "Server restart in 5 minutes" })

The bridge is server → client only, created lazily on first use (a RemoteEvent in ReplicatedStorage). The client only ever displays what it receives.

Configuration

Toast.configure() merges overrides into the active config at runtime. Defaults shown:

Toast.configure({
	-- Behaviour
	defaultLife = 3000,            -- ms
	defaultPosition = "top-right",
	defaultClosable = true,
	maxVisible = 5,                -- cap per position
	displayOrder = 1000,           -- ScreenGui DisplayOrder (keeps toasts above game UI)

	-- Stacked piles
	stacked = true,                -- false = classic vertical list
	expandedCount = 3,             -- toasts shown when a pile is expanded

	-- Animation & appearance
	animationDuration = 0.25,      -- seconds per animation phase
	animationEasing = Enum.EasingStyle.Quint,
	backgroundTransparency = 0.08, -- card background (0 = opaque)
	fontSize = 14,
	fontFace = Font.fromEnum(Enum.Font.Gotham), -- summary text uses its Bold weight

	-- Sounds
	soundEnabled = false,          -- true = play per-severity sounds automatically
	defaultVolume = 0.5,
})

Severity themes

Severity	Background	Accent
success	#F0FDF4	#4ADE80 / #16A34A
info	#EFF6FF	#60A5FA / #2563EB
warn	#FFFBEB	#FBB024 / #D97706
error	#FEF2F2	#F87171 / #DC2626
secondary	neutral	neutral

Every theme (colours, icon, sound) can be replaced globally through Toast.configure({ themes = ... }) or per toast with customTheme. The themes table passed to configure is merged per severity: severities you omit keep their current theme.

Running the demo

The repository ships with a keyboard-driven demo place:

rojo serve demo.project.json

Connect from Roblox Studio with the Rojo plugin, press Play, then:

Key	Action
1-6 (or numpad)	success · info · warn · error · secondary · custom theme
Shift	target the top-right corner (default)
Ctrl	target the bottom-right corner

The demo server script also fires a welcome toast to each joining player to exercise the server bridge.

Development

Tooling is pinned with Rokit:

rokit install

selene src demo          # lint
stylua --check src demo  # formatting
rojo sourcemap demo.project.json -o sourcemap.json
luau-lsp analyze --definitions=globalTypes.d.luau --sourcemap=sourcemap.json src demo

(globalTypes.d.luau comes from luau-lsp.)

All four checks run in CI on every push and pull request.
