Package Exports

@adraffy/ens-normalize
@adraffy/ens-normalize/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@adraffy/ens-normalize) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

import {ens_normalize} from '@adraffy/ens-normalize';
// npm i @adraffy/ens-normalize
// browser: https://unpkg.com/@adraffy/ens-normalize@latest/dist/index.min.js

// Primary API: string -> string
let normalized = ens_normalize('🚴‍♂️.eth'); // throws on invalid names
// ready for namehash
// note: does not enforce .eth TLD 3-character minimum

Instead of exposing an IDNA-like API (is_valid(), get_mapped(), etc.), this library exposes a single function which converts names to tokens:

// Secondary API: string -> Token[]
// turn a name into a list of tokens
let tokens = ens_tokenize('R💩\uFE0Fa\xAD./'); // never throws
// [
//     { 
//         type: 'mapped', 
//         cp: 82,         // input
//         cps: [ 114 ]    // output
//     }, 
//     { 
//         type: 'emoji',
//         input: [ 128169, 65039 ],  // input 
//         emoji: [ 128169, 65039 ],  // ideal form
//         cps: [ 128169 ]            // output
//     },
//     { type: 'valid', cps: [ 97 ] },
//     { type: 'ignored', cp: 173 },
//     { type: 'stop' },
//     { type: 'disallowed', cp: 47 }
// ]
