Axios DELETE in React — React Technical Interview Questions & Answers

Axios DELETE in React

Axios DELETE in React

  • DELETE with axios: await axios.delete('/api/items/' + id) then update UI state — filter that id out. Handle errors (toast). Optional optimistic update: remove first, put back on fail. Auth header if the API needs it.
  • Don’t leave the row on screen after 204. Don’t delete local state before the server if you can’t roll back.
  • Axios DELETE in React — click Delete → request DELETE /api/items/1 → list empty. Optimistic UI is extra credit.

Technical Interview Tip: DELETE then filter list state.

    await axios.delete("/api/items/" + id);
    setRows((rs) => rs.filter((r) => r.id !== id));
  }
  return (
    <ul>
      {rows.map((r) => (
        <li key={r.id}>
          {r.name}
          <button onClick={() => remove(r.id)}>Delete</button>
        </li>
      ))}
