Is there the way to encode base62 string in Angular 7?

Question

I'm trying to find the way to encode some of data the need to send back to the API.

I've tried Base-x library but it didn't work.

Is there any other way to do this without programmatically without any library?

Here's how courtesy Bret Lowrey

const base62 = {
  charset: '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
    .split(''),
  encode: integer => {
    if (integer === 0) {
      return 0;
    }
    let s = [];
    while (integer > 0) {
      s = [base62.charset[integer % 62], ...s];
      integer = Math.floor(integer / 62);
    }
    return s.join('');
  },
  decode: chars => chars.split('').reverse().reduce((prev, curr, i) =>
    prev + (base62.charset.indexOf(curr) * (62 ** i)), 0)
};

console.log(base62.encode(883314)); // Output - '3HN0'

console.log(base62.decode('3HN0')); // Output - 883314
