How to include

import Base62Str from "base62str";

If you want to use the library in nodejs then use require as follows:

const Base62Str = require("base62str").default;

Or, directly in the browser with no build step, via a <script> tag (exposes a Base62Str global):

<script src="https://unpkg.com/base62str/dist/index.global.js"></script>

To use

Create an instance

First create an instance:

  const base62 = Base62Str.createInstance();  

If you prefer you can create an instance with inverted CharacterSet:

  const base62 = Base62Str.createInstanceWithInvertedCharacterSet();

Encoding:

   const encodedString = base62.encodeStr("Hello World!");
   // encodedString => T8dgcjRGkZ3aysdN

Decoding:

   const decodedString = base62.decodeStr(encodedString);
   // decodedString => Hello World!
