You can install emoji-hash-gen using standard tools:

$> npm install emoji-hash-gen
# or
$> yarn add emoji-hash-gen

import { getHash } from 'emoji-hash-gen';

getHash('Hello, world'); // "🥳🤫🦁"
getHash('https://github.com/opa-oz/emoji-hash'); // "💥3️⃣🕕🕠🔇🈺"
getHash('@gahara'); // "✨🎸🍭❔🕕"

// You can restrct an amount of emojies in the hash
const longText = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industrys standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book';
getHash(longText, { length: 5 }) // "💥🔻🈲🈵😺"

Hash-function is fully deterministic - you will get the same result with the same set of input data:

import { getHash } from 'emoji-hash-gen';

getHash('@gahara') === getHash('@gahara'); // true
getHash('@gahara') === getHash('gahara'); // false

Description: Generates random hash from input string.

Interface:

getHash(input: string, options?: Options): string;

Description: Generates random integer, based on input string. Source

Interface:

getBitwise(str: string): number;

Description: A function used by getHash. Requires integer as input and generates an emoji-hash based on it

Interface:

transformBinary(input: number, options?: Options): string;

Description: Original library uses pre-generated table [number]: emoji, which used for hash-generation. useTable provides possibility to override the default table.

Interface:

useTable(newTable: EmojiTable): void;

Description: Default table contains 62 literals, generated from:

Re-generate:

$> yarn generate-table

Current table:

// 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
