Usage & Integration

Validate AWS ARN natively in your backend or frontend without copying regex strings.

Node / Edge

import { validate } from '@regexto/validators';

validate('aws-arn', '...');

Python

from regexto_validators import validate

validate("aws-arn", "...")

Go

import "github.com/regex-to/validators-go"

valid, err := validators.Validate("aws-arn", "...")

PHP

use RegexTo\Validators\Validator;

Validator::validate('aws-arn', '...');

Rust

use regexto_validators::validate;

let is_valid = validate("aws-arn", "...").unwrap();
