hyperdyperid
Fastest random ID and random string generation for Node.js
str3_36— generates random 3 character Base36 alphanumeric string.str5_36— generates random 5 character Base36 alphanumeric string.str6_36— generates random 6 character Base36 alphanumeric string.str10_36— generates random 10 character alphanumeric string.str(len [, alphabet])— generates any length random string using analphabet. Use likestr(10, '0123456789').hyperid— generates "hyperid" like ID.xorshift32— iterates through pseudo random numbers using "xorshift32" algorithm. This used to be the algorithm behindMath.random()in V8, then it switched to "xorshift64".randomU32(min, max)— generate a random 32-bit integer.
Usage
Install
yarn add hyperdyperid
Generate base36 10-character string:
const {str10_36} = require('hyperdyperid/lib/str10_36');
str10_36();
