# b62

Encode and decode strings to base62 (and others)

## Overview

The most popular [base62 encoder](https://www.npmjs.com/package/base62) and others only support converting a `number` to base62. This becomes a problem when trying to convert a big number with a precision higher than 52 bits like, for example, an UUID. Hence `b62`, which allows to convert strings (and not only) to base62.

> Meanwhile I've found [base-x](https://github.com/dcousens/base-x) which is much faster ([20x](https://gist.github.com/dmarcelino/879d4da2a0e0c32f7d74)) than b62! The only nuisance is that you need to supply a buffer. If performance is important to you, use base-x! In the future b62 may be changed to use base-x underneath.

## Instalation

```shell

npm i b62 -S

```

## Usage

```javascript

var b62 = require('b62');

var encoded = b62.encode("Hello World!");

// -> t8DGCJrgKz3AYSDn

var decoded = b62.decoded("t8DGCJrgKz3AYSDn");

// -> Hello World!

```

You can also use other bases, for example:

```javascript

var b64 = b62("-_0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");

var encoded = b64.encode("Hi this is b64 example");

// -> _6og_Oo4zN64zN646Qb0_zs43Hq4Lz

var decoded = b62.decoded("t8DGCJrgKz3AYSDn");

// -> Hi this is b64 example

```
