Install

NPM

$ npm install --save multibase

The type definitions for this package are available on http://definitelytyped.org/. To install just use:

$ npm install -D @types/multibase

In the Browser through <script> tag

Loading this module through a script tag will make the Multibase obj available in the global namespace.

<script src="https://unpkg.com/multibase/dist/index.min.js"></script>

Usage

Example

const multibase = require('multibase')

const bytes = multibase.encode('base58btc', new TextEncoder().encode('hey, how is it going'))

const decodedBytes = multibase.decode(bytes)
console.log(decodedBytes.toString())
// hey, how is it going

API

https://multiformats.github.io/js-multibase/

multibase - Prefixes an encoded Uint8Array with its multibase code

const multibased = multibase(<nameOrCode>, encodedBytes)

multibase.encode - Encodes Uint8Array into one of the supported encodings, prefixing it with the multibase code

const encodedBuf = multibase.encode(<nameOrCode>, <bytes>)

multibase.decode - Decodes Uint8Array or string

const decodedBuf = multibase.decode(bufOrString)

multibase.isEncoded - Checks if Uint8Array or string is encoded

const value = multibase.isEncoded(bytesOrString)
// value is the name of the encoding if it is encoded, false otherwise

multibase.encoding - Get the encoding by name or code

const value = multibase.encoding(nameOrCode)
// value is an instance of the corresponding `Base`

multibase.encodingFromData - Get the encoding from data either a string or Uint8Array

const value = multibase.encodingFromData(data)
// value is an instance of the corresponding `Base`

multibase.names

A frozen Object of supported base encoding names mapped to the corresponding Base instance.

multibase.codes

A frozen Object of supported base encoding codes mapped to the corresponding Base instance.

Supported Encodings, see src/constants.js
