Module Name: Form-to-Email Logic
Category: Admin
Summary:
This module is responsible for converting submitted form data into formatted email notifications. It provides a RESTful API endpoint to handle form submissions and send corresponding emails based on the provided data.
1. FastAPI Endpoint (Python/Node.js)
Here’s an example of a FastAPI endpoint that handles form-to-email logic:
from fastapi import APIRouter, Depends, HTTPException
from fastapi.responses import JSONResponse
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from typing import Dict, Any
from pydantic import BaseModel
router = APIRouter()
class FormData(BaseModel):
name: str
email: str
message: str
@router.post("/api/send-email", response_class=JSONResponse)
async def send_email(form_data: FormData) -> Dict[str, Any]:
"""
Handles form submission and sends a formatted email notification.
Args:
form_data (FormData): Data containing name, email, and message.
Returns:
Dict[str, Any]: Success or error message with appropriate status code.
"""
try:
# Configure email settings
sender_email = "notifications@example.com"
receiver_email = "admin@example.com"
password = "your-email-password" # Replace with actual password
# Create MIME object
msg = MIMEMultipart()
msg["From"] = sender_email
msg["To"] = receiver_email
msg["Subject"] = f"Form Submission - {form_data.name}"
# Add body to email
body = f"""
<html>
<body>
<h1>New Form Submission</h1>
<p>Name: {form_data.name}</p>
<p>Email: {form_data.email}</p>
<p>Message: {form_data.message}</p>
</body>
</html>
"""
msg.attach(MIMEText(body, "html"))
# Send email
with smtplib.SMTP("smtp.example.com", 587) as server:
server.starttls()
server.login(sender_email, password)
server.sendmail(sender_email, receiver_email, msg.as_string())
return {"message": "Email sent successfully!", "status": "success"}
except Exception as e:
raise HTTPException(
status_code=500,
detail=f"Failed to send email: {str(e)}"
)
2. React UI Snippet
Here’s a simple React component for capturing form data and sending it to the API endpoint:
import React, { useState } from 'react';
interface FormValues {
name: string;
email: string;
message: string;
}
export const ContactForm = () => {
const [formData, setFormData] = useState<FormValues>({
name: '',
email: '',
message: ''
});
const handleSubmit = async (e: React.FormEvent) => {
e.preventDefault();
try {
const response = await fetch('/api/send-email', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(formData),
});
if (!response.ok) {
throw new Error('Failed to send message');
}
alert('Message sent successfully!');
} catch (error) {
console.error('Error:', error);
alert('Failed to send message. Please try again.');
}
};
return (
<form onSubmit={handleSubmit} className="contact-form">
<div>
<label htmlFor="name">Name:</label>
<input
type="text"
id="name"
value={formData.name}
onChange={(e) => setFormData({ ...formData, name: e.target.value })}
required
/>
</div>
<div>
<label htmlFor="email">Email:</label>
<input
type="email"
id="email"
value={formData.email}
onChange={(e) => setFormData({ ...formData, email: e.target.value })}
required
/>
</div>
<div>
<label htmlFor="message">Message:</label>
<textarea
id="message"
value={formData.message}
onChange={(e) => setFormData({ ...formData, message: e.target.value })}
required
rows={4}
></textarea>
</div>
<button type="submit">Send Message</button>
</form>
);
};
3. Data Schema (Pydantic)
Here’s the Pydantic schema for validating form data:
from pydantic import BaseModel
class FormData(BaseModel):
name: str
email: str
message: str
class Config:
arbitrary_types_allowed = True
Explanation:
-
FastAPI Endpoint:
- Handles POST requests to
/api/send-email. - Validates form data using Pydantic models.
- Sends formatted emails using SMTP.
- Handles POST requests to
-
React UI:
- A simple form component that collects user input.
- Makes API calls to the FastAPI endpoint.
- Provides feedback for success and failure cases.
-
Data Schema:
- Uses Pydantic to define the structure of form data.
- Ensures all required fields are present and valid before processing.
This module provides a complete solution for converting form submissions into email notifications, with clear separation between frontend and backend components.
