Here is a possible implementation of the prompt collection page for FlowGPT using React, Node.js, and MongoDB to fulfill the acceptance criteria mentioned above: Front-end Implementation: - Create a new collection and give it a title and description: ```jsx import { useState } from 'react'; import axios from 'axios'; function NewCollectionForm() { const [title, setTitle] = useState(''); const [description, setDescription] = useState(''); const handleSubmit = async (event) => { event.preventDefault(); try { const response = await axios.post('/api/collections', { title, description }); console.log(response.data); // TODO: Redirect to the newly created collection page } catch (error) { console.error(error); } }; return (

Title setTitle(event.target.value)} /> Description

setDescription(event.target.value)} />

<button type='submit'>Create Collection</button>
    </form>
  );
}
```

- Add prompts to a collection by searching for them within FlowGPT:

```jsx
import { useState } from 'react';
import axios from 'axios';

function PromptSearchForm({ onAddPrompt }) {
  const [searchQuery, setSearchQuery] = useState('');
  const [prompts, setPrompts] = useState([]);

return (
    <form onSubmit={handleSearch}>
      <label htmlFor='search'>Search Prompts</label>
      <input type='text' id='search' value={searchQuery} onChange={(event) => setSearchQuery(event.target.value)} />
      <button type='submit'>Search</button>

<ul>
        {prompts.map((prompt) => (
          <li key={prompt._id}>
            {prompt.text}
            <button onClick={() => handleAddPrompt(prompt._id)}>Add to Collection</button>
          </li>
        ))}
      </ul>
    </form>
  );
}
```

- Remove prompts from a collection:

```jsx
import { useState } from 'react';
import axios from 'axios';

function PromptList({ prompts, onRemovePrompt }) {
  const handleRemovePrompt = (promptId) => {
    axios.delete(`/api/collections/prompts/${promptId}`)
      .then(() => onRemovePrompt(promptId))
      .catch((error) => console.error(error));
  };

return (
    <ul>
      {prompts.map((prompt) => (
        <li key={prompt._id}>
          {prompt.text}
          <button onClick={() => handleRemovePrompt(prompt._id)}>Remove</button>
        </li>
      ))}
    </ul>
  );
}
```

- Reorder the prompts within a collection:

```jsx
import { useState } from 'react';
import axios from 'axios';
import { DragDropContext, Droppable, Draggable } from 'react-beautiful-dnd';

return (
    <DragDropContext onDragEnd={handleDragEnd}>
      <Droppable droppableId='prompt-list'>
        {(provided) => (
          <ul {...provided.droppableProps} ref={provided.innerRef}>
            {prompts.map((prompt, index) => (
              <Draggable key={prompt._id} draggableId={prompt._id} index={index}>
                {(provided) => (
                  <li
                    ref={provided.innerRef</article></body></html>
