b62
Encode and decode strings to base62 (and others)
Overview
The most popular base62 encoder 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 which is much faster (20x) 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
npm i b62 -S
Usage
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:
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
