How to generate referral codes in javascript

You have to generate referral codes and for sure you want a quick answer, right?

Here’s my code which generate referral codes and save them in a txt file.

const fs = require('fs');

const CODE_LENGTH = 6;
const TOTAL_CODES_GENERATED = 100;

function generateCode(length) {
  const charset = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  let retVal = '';
  for (let i = 0, n = charset.length; i < length; ++i) {
    retVal += charset.charAt(Math.floor(Math.random() * n)).toUpperCase();
  }
  return retVal;
}

for (let index = 0; index < TOTAL_CODES_GENERATED; index++) {
  const code = `${generateCode(CODE_LENGTH)}\n`;
  fs.appendFile('codes.txt', code, (err) => {
    if (err) throw err;
  });
}

The length of the code can be changed using CODE_LENGTH, and the numbers of code can be changed by TOTAL_CODES_GENERATED.

Save this in a js file, for example generate-referral-codes.js, and then execute the file

node generate-referral-codes.js

In the same directory you’ll have now a generated codes.txt file with all the codes.

That’s it!
