description	Test the docs JSON repair demo against local backend changes before publishing. Use this when modifying docs/app.py or docs UI files and you need local end-to-end verification.

Docs Demo Local Test

Overview

Use this workflow to validate docs demo behavior with local code only, without relying on the deployed PythonAnywhere API. This is the default verification path for docs/app.py, docs/index.js, docs/index.html, docs/index.zh.html, and docs/styles.css changes.

Workflow

1. Start the local demo API server:

UV_CACHE_DIR=/tmp/uv-cache uv run --with flask --with flask-cors python docs/app.py

2. Start the local static site server:

python3 -m http.server 4173 --directory docs

3. Open http://127.0.0.1:4173/index.html.
4. In browser devtools, patch fetch so the page hits local API instead of PythonAnywhere:

() => {
  const target = "https://mangiucugna.pythonanywhere.com/api/repair-json";
  const local = "http://127.0.0.1:5000/api/repair-json";
  const originalFetch = window.fetch.bind(window);
  window.fetch = (input, init) => {
    let nextInput = input;
    if (typeof input === "string" && input === target) {
      nextInput = local;
    } else if (input instanceof Request && input.url === target) {
      nextInput = new Request(local, input);
    }
    return originalFetch(nextInput, init);
  };
  return "fetch patched";
}

5. Run a schema coercion check:

• Input JSON: {"value":"1",}
• Schema: {"type":"object","properties":{"value":{"type":"integer"}},"required":["value"]}
• Expected output JSON: {"value": 1}
• Expected log contains: Coerced string to integer

6. Confirm network request target is local:

• POST http://127.0.0.1:5000/api/repair-json

7. Capture screenshot if needed.
8. Stop both local servers with Ctrl+C.

Troubleshooting

• If uv run fails with cache permission errors, rerun with UV_CACHE_DIR=/tmp/uv-cache.
• If Flask modules are missing, keep using uv run --with flask --with flask-cors ....
• If output still matches production behavior, the fetch patch did not apply; reload and patch again before typing input.
