STORM

Compositor-based terminal UI framework. Fast. Layered. Unstoppable.

LIVE_SYSTEM.TSX

import { render, Box, Text, Spinner } from "@orchetron/storm-tui"; const App = () => ( <Box borderStyle="round" padding={1}> <Spinner type="dots" /> <Text bold color="#82AAFF"> Storm is running </Text> </Box> ); render(<App />).waitUntilExit();

Performance DNA

Numbers that matter.

Skip Rate

Cell-level diff renders only changed characters. 97% of the terminal is untouched on a typical frame.

Frame Time

Sub-millisecond imperative rendering path. No React reconciliation for scroll, animation, or live data.

Components

92 components, 19 AI widgets, 82 hooks, 15 headless behaviors. Everything you need, built in.

Differentiators

ENGINEERED
DIFFERENT

The architecture decisions that make Storm fast, flexible, and production-ready.

grid_on

Cell-Level Rendering

Storm diffs at the individual character level -- only changed cells are written to the terminal. On a typical frame, 97% of the screen is untouched. Typed-array buffers eliminate GC pressure entirely.

speed

Dual-Speed Architecture

Structure your UI with React components. Animate at 60fps with imperative rendering. Two rendering paths, zero compromise -- declarative when you want clarity, imperative when you need speed.

terminal

SSH App Serving

Serve your terminal UI over SSH with built-in auth, rate limiting, and session management. Each connection gets its own isolated React tree with full keyboard, mouse, and resize support.

history

Time-Travel DevTools

Record every frame. Scrub back and forth through render history. Inspect component trees, measure performance, audit accessibility -- all built in.

webhook

82 Hooks + 15 Headless Behaviors

Build any interaction pattern without writing keyboard handling from scratch. Select, list, menu, tree, table, form, calendar -- tested logic, your visual design.

extension

Plugin Ecosystem

Extend everything. Async setup, scoped effects, inter-plugin communication, topological dependency sorting. Build plugins that ship as npm packages.

Internals

Rendering Pipeline

From React tree to ANSI escape codes. Five stages. Sub-millisecond.

Stage 01

React Tree

<Box>

├─ <Text>

├─ <ScrollView>

│ ├─ <List>

│ └─ <Item> MUT

└─ <StatusBar>

Custom reconciler transforms JSX into a normalized element tree.

Stage 02

Layout Engine

flex:2

Pure-TS flexbox + CSS grid. Computes position and size for every node.

Stage 03

Cell Buffer

char

attr

char

attr

Int32Array + Uint8Array

Typed arrays: char, fg, bg, attrs per cell. Double-buffered.

Stage 04

Diff Engine

14 skipped 2 written

97% of cells skipped. Only mutations written.

Stage 05

Terminal

React Tree / Layout Engine / Cell Buffer / Diff Engine / Terminal

Architecture 01

Cell-Level Diffing

A 200x50 terminal has 10,000 cells. On a cursor blink, 9,970 cells are identical to the previous frame. Storm writes only the 30 that changed.

Traditional 10,000 cells rewritten

Every cell. Every frame.

Storm 2 cells written

97% untouched. Zero waste.

cells per frame

cells written

skip rate

No Cell objects. No GC. Int32Array + Uint8Array — raw typed memory. At 60fps, that's 600,000 cells/second with zero garbage collection.

Architecture 02

Dual-Speed Rendering

React reconciliation for structural changes. Imperative requestRender() for scroll, animation, and live data — bypasses React entirely. Two rendering paths, one framework.

setState path ~5-10ms per update

reconcile

→

layout

→

paint

→

diff

4 stages

requestRender() path <0.5ms per update

paint

→

diff

2 stages — 10-20x faster

Use useState for structural changes (new screens, adding items). Use requestRender() for anything that updates frequently — scroll, animation, live metrics. Same framework, two speed modes.
