Site: deduplicate the CodeSandbox JS/TS sandbox define-API payload in index.jsx

packages/tdesign-react/site/src/components/codesandbox/index.jsxと、packages/tdesign-react/site/test/codesandbox.test.mjsにあるリグレッション仕様を読みます。JSとTSのファイルセットを維持し、条件付きのtsconfig.jsonも含めて、共有されるCodeSandboxペイロードとリクエストパスを抽出します。Nodeのテスト仕様を実行し、Sandboxの作成に成功したときに返されたURLが引き続き開かれることを確認します。

Problem

packages/tdesign-react/site/src/components/codesandbox/index.jsx issues the CodeSandbox define request through two fully duplicated fetch blocks — one for TypeScript demos and one for JS demos — that differ only in file extensions (src/main.tsx vs src/main.jsx, src/demo.tsx vs src/demo.jsx, and the extra tsconfig.json for TS). Any future fix to the shared payload (manifest, index.html, styles, entry file) must be edited in two places and can silently drift apart.

Note: this issue is scoped to the index.jsx payload deduplication only; the separate ReactDOM.render -> createRoot template change in content.js is tracked elsewhere and is intentionally out of scope here.

Proposal

Extract a single shared code path that builds the file map (parameterized by the demo language for extensions and the conditional tsconfig.json) and posts it to https://codesandbox.io/api/v1/sandboxes/define?json=1, keeping identical filenames, identical shared files, and identical success behavior (opening https://codesandbox.io/s/<id>?file=/src/demo.<ext>).

Scope

Site only: packages/tdesign-react/site/src/components/codesandbox/index.jsx. No component API, type.ts, defaultProps.ts, or submodule changes.

Validation

Regression tests are pending — a node:test spec at packages/tdesign-react/site/test/codesandbox.test.mjs asserts a single define-API request path while preserving both JS and TS file sets; it currently fails on the duplicated baseline. Manual check: pnpm dev, open a component page, generate a JS and a TS demo sandbox and confirm identical payloads other than the language-specific files.

Regression test

New regression file: packages/tdesign-react/site/test/codesandbox.test.mjs
import assert from 'node:assert/strict';
import { readFileSync } from 'node:fs';
import { dirname, join } from 'node:path';
import { fileURLToPath } from 'node:url';

const indexSource = readFileSync(join(codesandboxDir, 'index.jsx'), 'utf8');

// Regression: the CodeSandbox "define" request must be issued through a single
// shared code path. The baseline builds the whole fetch payload twice (once for
// `.tsx` demos, once for `.jsx` demos), so any template fix has to be edited in
// two places and can drift apart. On the unfixed source this assertion fails
// with `2 !== 1`.
test('CodeSandbox define API request is built once and shared for JS and TS demos', () => {
  const occurrences = indexSource.match(/codesandbox\.io\/api\/v1\/sandboxes\/define/g) ?? [];
  assert.equal(occurrences.length, 1);
});

// Boundaries of the refactor: deduplicating the payload must not drop support
// for either demo language or change what the action does on success.
