Web Frameworks

Email checker for web frameworks. React, Next.js, Vue, Django, Laravel, Go integration guides.

Choose your web framework and integrate email verification into your applications. Whether you're building frontend applications with modern JavaScript frameworks or backend services with Python, PHP, or Go, we have detailed guides for each.

Frontend Frameworks

Build real-time email validation directly into your user interfaces.

React

Hooks, components, and context integration

Next.js

Server actions, API routes, and RSC

Vue.js

Composables, components, and Nuxt 3

Backend Frameworks

Implement server-side email verification with validation rules, middleware, and database integration.

PHP

Laravel

Validation rules, middleware, service providers

Python

Django

Model validators, forms, REST framework

FastAPI

Pydantic models, dependencies, async handlers

Go

Gin

Middleware, handlers, request binding

Fiber

Express-like API, high performance

Common Implementation Patterns

1. Real-Time Validation

Verify emails as users type with debouncing to minimize API calls.

// React example
import { useEmailVerification } from '@emailverify/react';

function EmailField() {
  const { verify, result, isLoading } = useEmailVerification({
    debounceMs: 500
  });

  return (
    <div>
      <input
        type="email"
        onBlur={(e) => verify(e.target.value)}
      />
      {result?.status === 'valid' && <p>✓ Valid email</p>}
      {result?.status === 'invalid' && <p>✗ Invalid email</p>}
    </div>
  );
}

2. Server-Side Validation

Always verify on the backend before processing data.

# Django example
from django.db import models
from .validators import validate_email_deliverable

class User(models.Model):
    email = models.EmailField(
        validators=[validate_email_deliverable]
    )
    name = models.CharField(max_length=255)

3. Form Integration

Integrate with popular form libraries for seamless validation.

// React Hook Form example
const validateEmail = async (email) => {
  const result = await verify(email);
  if (result.status === 'invalid') {
    throw new Error('Invalid email address');
  }
};

// Use with React Hook Form
<input
  type="email"
  {...register('email', {
    validate: validateEmail
  })}
/>

4. Caching Results

Reduce API costs by caching verification results.

# Django example with cache
from django.core.cache import cache

def verify_with_cache(email):
    cached = cache.get(f'email_verify:{email}')
    if cached:
        return cached

    result = client.verify(email)
    cache.set(f'email_verify:{email}', result, 3600)
    return result
