To implement the "Polling Notes" feature with your tech stack, you can follow these steps:
-
Frontend (React Native):
- Create a component for displaying the poll question and options.
- Implement a voting system where users can select an option and submit their vote.
- Display the results of the poll based on the votes received.
-
Backend API (.NET API):
- Create an endpoint to handle the creation of polls.
- Create an endpoint to handle the submission of votes.
- Create an endpoint to retrieve the results of the poll.
- Implement the necessary logic to store and update the poll data in the MSSQL database.
-
Database (MSSQL):
- Create a table to store the poll data, including the question and options.
- Create a table to store the votes, including the user ID and the selected option.
Here's a high-level example of how you can structure your code:
Frontend (React Native):
// PollComponent.js
import React, { useState } from 'react';
import { View, Text, Button, FlatList } from 'react-native';
const PollComponent = ({ poll, onVote }) => {
const [selectedOption, setSelectedOption] = useState(null);
const handleVote = () => {
onVote(selectedOption);
};
return (
<View>
<Text>{poll.question}</Text>
<FlatList
data={poll.options}
keyExtractor={(option) => option.id}
renderItem={({ item }) => (
<Button
title={item.text}
onPress={() => setSelectedOption(item.id)}
/>
)}
/>
<Button title="Vote" onPress={handleVote} disabled={!selectedOption} />
</View>
);
};
export default PollComponent;Backend API (.NET API):
// PollsController.cs
using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
using System.Linq;
[ApiController]
[Route("[controller]")]
public class PollsController : ControllerBase
{
private readonly PollsContext _context;
public PollsController(PollsContext context)
{
_context = context;
}
[HttpPost("create")]
public IActionResult CreatePoll([FromBody] Poll poll)
{
_context.Polls.Add(poll);
_context.SaveChanges();
return Ok();
}
[HttpPost("vote")]
public IActionResult Vote([FromBody] Vote vote)
{
var poll = _context.Polls.Find(vote.PollId);
if (poll == null)
{
return NotFound();
}
poll.Votes.Add(vote);
_context.SaveChanges();
return Ok();
}
[HttpGet("results/{id}")]
public IActionResult GetPollResults(int id)
{
var poll = _context.Polls.Find(id);
if (poll == null)
{
return NotFound();
}
var results = poll.Votes.GroupBy(v => v.OptionId)
.Select(g => new { OptionId = g.Key, Count = g.Count() })
.ToList();
return Ok(results);
}
}Database (MSSQL):
// PollsContext.cs
using Microsoft.EntityFrameworkCore;
public class PollsContext : DbContext
{
public DbSet<Poll> Polls { get; set; }
public DbSet<Vote> Votes { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer("your_connection_string");
}
}
public class Poll
{
public int Id { get; set; }
public string Question { get; set

**Frontend Code (Typescript) for Admin and Member Components**
### Admin Component (Poll Creation)
```typescript
// admin.component.ts
import React, { useState } from 'react';
import axios from 'axios';
interface Poll {
question: string;
options: string[];
}
const AdminComponent = () => {
const [poll, setPoll] = useState<Poll>({ question: '', options: [] });
const [option, setOption] = useState('');
const handleAddOption = () => {
setPoll({ ...poll, options: [...poll.options, option] });
setOption('');
};
const handleCreatePoll = async () => {
try {
const response = await axios.post('/api/polls', poll);
console.log(response.data);
} catch (error) {
console.error(error);
}
};
return (
<div>
<h2>Create Poll</h2>
<input
type="text"
value={poll.question}
onChange={(e) => setPoll({ ...poll, question: e.target.value })}
placeholder="Enter poll question"
/>
<br />
<input
type="text"
value={option}
onChange={(e) => setOption(e.target.value)}
placeholder="Enter option"
/>
<button onClick={handleAddOption}>Add Option</button>
<ul>
{poll.options.map((option, index) => (
<li key={index}>{option}</li>
))}
</ul>
<button onClick={handleCreatePoll}>Create Poll</button>
</div>
);
};
export default AdminComponent;// member.component.ts
import React, { useState, useEffect } from 'react';
import axios from 'axios';
interface Poll {
id: number;
question: string;
options: string[];
votes: { [option: string]: number };
}
const MemberComponent = () => {
const [polls, setPolls] = useState<Poll[]>([]);
const [selectedPoll, setSelectedPoll] = useState<Poll | null>(null);
const [selectedOption, setSelectedOption] = useState('');
useEffect(() => {
axios.get('/api/polls')
.then(response => {
setPolls(response.data);
})
.catch(error => {
console.error(error);
});
}, []);
const handleVote = async () => {
try {
const response = await axios.post(`/api/polls/${selectedPoll.id}/vote`, { option: selectedOption });
console.log(response.data);
} catch (error) {
console.error(error);
}
};
return (
<div>
<h2>Vote on Polls</h2>
<select value={selectedPoll} onChange={(e) => setSelectedPoll(polls.find(poll => poll.id === parseInt(e.target.value)))}>
<option value="">Select a poll</option>
{polls.map(poll => (
<option key={poll.id} value={poll.id}>{poll.question}</option>
))}
</select>
{selectedPoll && (
<div>
<h3>{selectedPoll.question}</h3>
<ul>
{selectedPoll.options.map(option => (
<li key={option}>
<input
type="radio"

{option}
</li>
))}
</ul>

});Note: This is a basic implementation and you may want to add additional features such as user authentication, poll validation, and error handling.
