# 🛡️ univalidator
[](https://pypi.org/project/univalidator/)
[](https://pypi.org/project/univalidator/)
[](https://github.com/shaileshpandit141/univalidator/blob/main/LICENSE)
A **flexible, extensible, and type-safe** Python validation framework designed to validate data with ease.
Currently supports **email validation** (via regex and MX records) and **composite validators** for running multiple checks.
## ✨ Features
- **Abstract Validator Interface** — define your own validators easily.
- **Regex-based Validation** — for any string patterns.
- **Email Format Validation** — RFC-compliant pattern check.
- **MX Record Validation** — verifies if an email domain can receive emails.
- **Composite Validation** — run multiple validators in sequence.
- **Type Safe** — written with modern Python type hints.
## 📦 Installation
- **By using uv:**
```bash
uv add univalidator
````
- **By using pip:**
```bash
pip install univalidator
````
## 📚 API Reference
### **1️ BaseValidator[T]**
Abstract base for all validators.
**Custom validators** must implement the `validate(data: T) -> bool` method.
### **2️ RegexValidator[T]**
Validates data against a regular expression.
```python
from univalidator.validators import RegexValidator
validator = RegexValidator[str](r"^\d{4}-\d{2}-\d{2}$") # YYYY-MM-DD format
validator.validate("2025-08-15") # True
validator.validate("15-08-2025") # False
```
### **3️ RegexEmailValidator[T]**
Validates email format using a regex pattern.
Uses a default pattern, but you can pass your own.
```python
from univalidator.validators import RegexEmailValidator
validator = RegexEmailValidator[str]()
validator.validate("user@example.com") # True
validator.validate("invalid-email") # False
```
### **4️ MXEmailRecordValidator[T]**
Checks if an email’s domain has MX DNS records.
```python
from univalidator.validators import MXEmailRecordValidator
validator = MXEmailRecordValidator[str]()
validator.validate("user@gmail.com") # True
validator.validate("user@no-such-domain.com") # False
```
Restrict to specific domains:
```python
validator = MXEmailRecordValidator[str](allowed_domains=["example.com", "gmail.com"])
```
### **5️ CompositeValidator[T]**
Runs multiple validators in sequence.
All validators must pass for the data to be valid.
```python
from univalidator.composites import CompositeValidator
from univalidator.validators import RegexEmailValidator, MXEmailRecordValidator
validator = CompositeValidator[str]([
RegexEmailValidator(),
MXEmailRecordValidator()
])
validator.validate("user@gmail.com") # True
```
## 🧪 Testing
```bash
uv add pytest
uv run pytest tests
```
## 🌟 Example: Full Email Validation
```python
from univalidator.composites import CompositeValidator
from univalidator.validators import RegexEmailValidator, MXEmailRecordValidator
validator = CompositeValidator[str]([
RegexEmailValidator(),
MXEmailRecordValidator()
])
email = "test@gmail.com"
if validator.validate(email):
print("Valid email with active domain!")
else:
print("Invalid email.")
```
## 🛠️ Planned Features
- 🔒 Add more Validators
