normail

Light library that tries to normalize emails

Usage

As a sipmple function

import { mormalize } from 'normail';

const normalized = await normalize('[email protected]')
// Output
// NormalizedEmail {
//     original: '[email protected]',
//     normalized: '[email protected]',
//     provider: 'google.com',
//     error: undefined
// }

Or you can create a new function that will cache the results

import { createNormalizer } from 'normail';

// create the normalizer only once
const normalize = createNormalizer({
    ttl: 300, // cache the results for 300 seconds
    max: 100  // max entries to keep on cache
})

// used it more times
const normalized = await normalize('[email protected]')
// Output as before
