A generator of numbers that passes the validation of Luhn algorithm or Luhn formula, also known as the "modulus 10" or "mod 10" algorithm
npm install luhn-generator --save
- ECMAScript Harmony
import luhn from '../dist/luhn'; luhn.generate(1, { pad: 12 }); // 000000000018
- CommonJS
$ node > const luhn = require('../dist/luhn'); > luhn.generate(1, { pad: 12 }); // 000000000018

Generate Luhn "check digit" for number 1:
luhn.checksum(1); // 8
luhn.checksum(12); // 5Generate number that will pass Luhn algorithm validation:
luhn.generate(1); // 18
luhn.generate(12); // 125
luhn.generate(1, { pad: 5 }); // 00018Generate random number that will pass Luhn algorithm validation:
luhn.random(12); // 6436204626980
luhn.random(50); // 54833184596638864915195736286128781213916608803535
luhn.random(12, { pad: 50 }); // 00000000000000000000000000000000000004591785326079Validate number with Luhn algorithm:
luhn.validate(1); // false
luhn.validate(18); // true
luhn.validate(125); // true- Add page with examples
