Code Review

This PR upgrades msw from ^0.24.2 to ^0.49.3 to fix a security vulnerability. This is a large version jump that introduces breaking changes. The way msw handles request bodies has changed, and your mock handlers in src/__test__/mocks/handlers.js must be updated to use await req.json() to parse request bodies. Without these changes, your tests will fail. Please see the specific comment for details on the required code modifications.

"@testing-library/user-event": "^12.1.10",
"mocha": "^8.2.1",
"msw": "^0.24.2"
"msw": "^0.49.3"

critical

Upgrading msw to this version introduces a critical breaking change that will cause your tests to fail.

Starting from [email protected], req.body is a ReadableStream, not a plain object. You must now use await req.json() to parse the JSON body of a request. Your existing handlers in src/__test__/mocks/handlers.js that use req.body directly will need to be updated.

Specifically, the POST and PATCH handlers need to be converted to async functions and use await req.json().

Example for the POST handler:

// src/__test__/mocks/handlers.js
rest.post("http://localhost:4000/items", async (req, res, ctx) => {
  id++;
  const body = await req.json();
  const item = { id, ...body };
  items.push(item);
  return res(ctx.json(item));
}),

Example for the PATCH handler:

// src/__test__/mocks/handlers.js
rest.patch("http://localhost:4000/items/:id", async (req, res, ctx) => {
  const { id } = req.params;
  if (isNaN(parseInt(id))) {
    return res(ctx.status(404), ctx.json({ message: "Invalid ID" }));
  }
  const itemIndex = items.findIndex((item) => item.id === parseInt(id));
  const body = await req.json();
  items[itemIndex] = { ...items[itemIndex], ...body };
  return res(ctx.json(items[itemIndex]));
}),

Please apply these changes to prevent your test suite from breaking.
