Verification Code Generator.

This is a package that generate verification code using random numbers. For example you can generate numbers like 12789 and use it as a verification code with your magic.

Why this simple package?

I created this package, when i was working on a certain application where I have to send the verification codes to the users via email. So I take it as a good idea to create it as a package that using regular functions for reusability.

Installation

yarn

yarn add @crispengari/random-verification-codes

npm

npm install @crispengari/random-verification-codes

TypeScript

You don't have to explicitly install the types for this package because it was created using typescript.

Basic usage

import {
  generateVerificationCode,
  generateInteger,
} from "@crispengari/random-verification-codes";

const randomInt = generateInteger(); // returns a random number between 0 and 9 inclusive

const generated = await generateVerificationCode(); // generate a random verification 5 digit as a string by default

1. generateVerificationCode() A promise function that accepts three argument and returns a string or an integer based on the arguments passed:

• **numberOfDigits**- a number which specifies length of the generated code default is 5.
• **allowZeroStart**- a boolean which specifies wether the verification code to start with a zero or not default is true.
• **returnAsString**- a boolean which specifies wether the verification should be a string or a number default is true.

Basic example

1. es6

import {
  generateVerificationCode,
  generateInteger,
} from "@crispengari/random-verification-codes";

const main = async () => {
  const generated = await generateVerificationCode();
  console.log(generated);
};
main();

2. es5

import {
  generateVerificationCode,
  generateInteger,
} from "@crispengari/random-verification-codes";

generateVerificationCode().then((generatedCode) => console.log(generatedCode));
