Package Exports

@krobinalpha/ens-namehash
@krobinalpha/ens-namehash/dist/esm/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 (@krobinalpha/ens-namehash) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Dotarb ENS Namehash

A javascript library for generating Ethereum Name Service (ENS) namehashes per spec.

Installation

yarn add @krobinalpha/ens-namehash

npm install @krobinalpha/ens-namehash -S

Usage

var namehash = require('@krobinalpha/ens-namehash');
var hash = namehash.hash('robin.eth');

// Also supports normalizing strings to ENS compatibility:
var input = getUserInput();
var normalized = namehash.normalize(input);

typescript

import namehash from '@krobinalpha/ens-namehash';
const hash = namehash.hash('robin.eth');
// '0xde9b09fd7c5f901e23a3f19fecc54828e9c848539801e86591bd9801b019f84f'

// Also supports normalizing strings to ENS compatibility:
const input = getUserInput();
const normalized = namehash.normalize(input);

Security Warning

ENS Supports UTF-8 characters, and so many duplicate names are possible. For example:

faceboоk.eth
facebook.eth

The first one has non-ascii chars. (control+F on this page and search for facebook, only the second one will match).

namehash.normalize() doesn't automagically remap those, and so other precautions should be taken to avoid user phishing.

Development

This module supports advanced JavaScript syntax, but exports an ES5-compatible module. To re-build the exported module after making changes, run npm run bundle (must have browserify installed).
