Background

(Forked from digitalbazaar/cborld v4 to provide TypeScript and ReactNative compatibility.)

This library provides a CBOR-LD Processor for Web browsers, React Native, and Node.js applications.

Install

NPM

npm install @digitalcredentials/cborld

Git

To install locally (for development):

git clone https://github.com/digitalcredentials/cborld.git
cd cborld
npm install

Usage

This library provides two primary functions for encoding and decoding CBOR-LD data.

Encode to CBOR-LD

To encode a JSON-LD document as CBOR-LD:

import {encode, documentLoader} from '@digitalcredentials/cborld';

const jsonldDocument = {
  '@context': 'https://www.w3.org/ns/activitystreams',
  type: 'Note',
  summary: 'CBOR-LD',
  content: 'CBOR-LD is awesome!'
};

// encode a JSON-LD Javascript object into CBOR-LD bytes
const cborldBytes = await encode({jsonldDocument, documentLoader});

To decode a CBOR-LD document to JSON-LD:

import {decode, documentLoader} from '@digitalcredentials/cborld';

// get the CBOR-LD bytes
const cborldBytes = await fs.promises.readFile('out.cborld');

// decode the CBOR-LD bytes into a Javascript object
const jsonldDocument = await cborld.decode({cborldBytes, documentLoader});

API

Functions

Typedefs

encode(options) ⇒ Promise<Uint8Array>

Kind: global function Returns: Uint8Array - - The encoded CBOR-LD bytes.

decode(options) ⇒ Promise<object>

Decodes a CBOR-LD byte array into a JSON-LD document.

Kind: global function Returns: object - - The decoded JSON-LD Document.

diagnosticFunction : function

A diagnostic function that is called with diagnostic information. Typically set to console.log when debugging.

Kind: global typedef

documentLoaderFunction ⇒ string
