@opentui/solid

Solid.js support for OpenTUI.

Installation

bun install solid-js@^1.9 @opentui/solid

Usage

1. Add jsx config to tsconfig.json:

{
  "compilerOptions": {
    "jsx": "preserve",
    "jsxImportSource": "@opentui/solid"
  }
}

2. Add preload script to bunfig.toml:

preload = ["@opentui/solid/preload"]

3. Add render function to index.tsx:

import { render } from "@opentui/solid"

render(() => <text>Hello, World!</text>)

4. Run with bun index.tsx.

5. To build use Bun.build (source):

import solidPlugin from "@opentui/solid/bun-plugin"

await Bun.build({
  entrypoints: ["./index.tsx"],
  target: "bun",
  outdir: "./build",
  plugins: [solidPlugin],
  compile: {
    target: "bun-darwin-arm64",
    outfile: "app-macos",
  },
})

Core Concepts

Components

OpenTUI Solid exposes intrinsic JSX elements that map to OpenTUI renderables:

• Layout & Display: text, box, scrollbox, ascii_font
• Input: input, textarea, select, tab_select
• Code & Diff: code, line_number, diff
• Text Modifiers: span, strong, b, em, i, u, br, a

API Reference

render(node, rendererOrConfig?)

Render a Solid component tree into a CLI renderer. If you omit rendererOrConfig, render() creates a renderer with default options. render() returns a promise that resolves after the initial mount. Destroying the renderer disposes the Solid root.

import { render } from "@opentui/solid"

render(() => <App />)

Parameters:

• node: Function returning a JSX element.
• rendererOrConfig?: CliRenderer instance or CliRendererConfig.

testRender(node, options?)

Create a test renderer for snapshots and interaction tests.

import { testRender } from "@opentui/solid"

const testSetup = await testRender(() => <App />, { width: 40, height: 10 })

extend(components)

Register custom renderables as JSX intrinsic elements.

import { extend } from "@opentui/solid"

extend({ customBox: CustomBoxRenderable })

Solid calls the constructor with { id } only. After construction, Solid applies each JSX prop to the instance. A class that reads a value only from its constructor options does not get that value from JSX.

getComponentCatalogue()

Returns the current component catalogue that powers JSX tag lookup.

Hooks

• useRenderer()
• onResize(callback)
• onFocus(callback)
• onBlur(callback)
• useTerminalDimensions()
• useKeyboard(handler, options?)
• usePaste(handler)
• useSelectionHandler(handler)
• useTimeline(options?)

Portal

Render children into a different mount node. Use it for overlays and tooltips.

import { Portal } from "@opentui/solid"
;<Portal mount={renderer.root}>
  <box border>Overlay</box>
</Portal>

Dynamic

Render arbitrary intrinsic elements or components dynamically.

import { Dynamic } from "@opentui/solid"
;<Dynamic component={isMultiline() ? "textarea" : "input"} />

Components

Layout & Display

• text: styled text container
• box: layout container with borders, padding, and flex settings
• scrollbox: scrollable container
• ascii_font: ASCII art text renderer

For QR codes, call registerQRCode() from @opentui/qrcode/solid. It registers the qr_code element.

Input

• input: single-line text input
• textarea: multi-line text input
• select: list selection
• tab_select: tab-based selection

Code & Diff

• code: syntax-highlighted code blocks
• line_number: line-numbered code display with diff/diagnostic helpers
• diff: unified or split diff viewer

Text Modifiers

Use these only inside a text component:

• span: inline styled text
• strong/b: bold text
• em/i: italic text
• u: underline text
• br: line break
• a: link text with href
