プラグイン: Val Town

説明

次のような場合に使用: ユーザーインターフェースを持つ val を構築する場合 — ダッシュボード、Web アプリ、ランディングページ、フォーム、管理ツール、ブラウザでユーザーが目にするあらゆるもの。JSX/React の規約、Twind/Tailwind スタイリング、React バージョンのピン留め、view-source リンク要件、そして避けるべき事項（テンプレート文字列 HTML、外部アセット）をカバーしています。

原文を表示

Use when building any val with a user interface — dashboards, web apps, landing pages, forms, admin tools, anything users see in a browser. Covers JSX/React conventions, Twind/Tailwind styling, React version pinning, the view-source link requirement, and what to avoid (template-string HTML, external assets).

本文

React UI

For any val that renders a UI, prefer to build it with React components in .tsx files, unless the user states otherwise. The templates/react-hono-starter template is set up for this — start there with remix_val instead of building from scratch.

File conventions

Put markup, styles, and scripts in real files — avoid template literal strings (e.g. new Response(\<html>...</html>`)`). Code in template strings has no syntax highlighting, no linting, no type checking, and is unreviewable.

.tsx — React/JSX components, any UI with logic or interactivity
.html — purely static markup
.ts — server code and scripts

Build UI component by component in .tsx files. Compose small components rather than rendering one giant page.

Styling: Twind + Tailwind

Prefer Twind to apply Tailwind utility classes at runtime — no build step required. Add the script to your HTML shell:

<script src="https://cdn.twind.style" crossorigin></script>

Then use Tailwind classes directly in JSX:

<div className="flex items-center gap-4 p-6 rounded-lg bg-white shadow">
  <h1 className="text-2xl font-bold">Hello</h1>
</div>

Avoid inline <style> tags, CSS-in-JS objects, or separate .css files, unless the user says otherwise.

View source link

Every UI val should expose a way for users to see and remix its source. Both parts are required:

Backend route:

import { parseVal } from "https://esm.town/v/std/utils/index.ts";
app.get("/source", (c) => c.redirect(parseVal().links.self.val));

Visible link in the frontend:
```
<a href="/source">view source</a>
```

React version pinning

A common error — "Cannot read properties of null (reading 'useState')" — means a React sub-dependency is loading a different React version. Pin all React-related imports to 18.2.0:

import SomeLib from "https://esm.sh/some-lib?deps=react@18.2.0,react-dom@18.2.0";

Assets

Do not use external images or hosted assets that may break. Prefer:

Emojis or unicode symbols
Inline SVG
Icon fonts via CDN (Lucide, Font Awesome)

Surfacing client-side errors

To send browser errors back to val logs (visible via get_logs), include this script in your HTML shell:

<script src="https://esm.town/v/std/catch"></script>

Verifying changes

After editing a UI val, call fetch_val_endpoint to confirm the page renders without error, then check get_logs for any client-side errors. Don't report the change as done without both.
