PII normalization and SHA256 hashing for Meta CAPI and ad platforms
npm install @hammr/normalizerPII normalization and SHA256 hashing for ad platforms (Meta CAPI, Google, TikTok).
``bash`
npm install @hammr/normalizer
`typescript
import { Normalizer } from '@hammr/normalizer';
const normalizer = new Normalizer();
// Normalize and hash user data
const result = await normalizer.normalize({
email: ' Test@Example.COM ',
phone: '+1 (555) 123-4567',
firstName: 'John',
lastName: 'Doe',
city: 'San Francisco',
state: 'CA',
zipCode: '94102',
country: 'US'
});
console.log(result);
// {
// em: 'b4c9a289323b21a01c3e807f0769a8be...', // SHA256 hash
// ph: '15551234567', // E.164 format
// fn: 'john',
// ln: 'doe',

`
- Email normalization (trim, lowercase, hash)
- Phone normalization (E.164 format, hash)
- Name normalization (lowercase, no spaces)
- Address normalization (city, state, zip, country)
- SHA256 hashing via Web Crypto API
- Gender and DOB normalization
- Type-safe with TypeScript
`typescript
const normalizer = new Normalizer();
// Normalize full user data
const result = await normalizer.normalize(userData);
// Individual normalizers
normalizer.normalizeEmail('test@example.com'); // 'test@example.com'
normalizer.normalizePhone('+1 555-123-4567'); // '15551234567'
normalizer.normalizeName('John Doe'); // 'johndoe'
normalizer.normalizeCity('San Francisco'); // 'sanfrancisco'
normalizer.normalizeState('CA'); // 'ca'
normalizer.normalizeZipCode('94102-1234'); // '94102'
normalizer.normalizeCountry('United States'); // 'us'
normalizer.normalizeGender('Male'); // 'm'
normalizer.normalizeDateOfBirth('1990-01-15'); // '19900115'
`
`typescript
import { sha256 } from '@hammr/normalizer';
const hash = await sha256('test@example.com');
// 'b4c9a289323b21a01c3e807f0769a8be7e60c8ece9eb35e14e9f3b7e5c1d2e3f'
