What is cbor?

The 'cbor' npm package is used for encoding and decoding data in the Concise Binary Object Representation (CBOR) format. CBOR is a binary data serialization format that is designed to be small, fast, and suitable for constrained environments. It is often used in IoT, web, and mobile applications where efficiency is critical.

What are cbor's main functionalities?

Encoding Data

This feature allows you to encode JavaScript objects into CBOR format. The example demonstrates encoding a simple object asynchronously.

const cbor = require('cbor');
const data = { key: 'value' };
cbor.encodeAsync(data).then(encoded => {
  console.log(encoded);
});

Decoding Data

This feature allows you to decode CBOR data back into JavaScript objects. The example shows how to decode a CBOR-encoded buffer.

const cbor = require('cbor');
const encodedData = Buffer.from('a2616b65796576616c7565', 'hex');
cbor.decodeFirst(encodedData).then(decoded => {
  console.log(decoded);
});

Streaming Encoding

This feature supports streaming encoding, which is useful for handling large datasets or continuous data streams. The example demonstrates encoding data in a stream.

const cbor = require('cbor');
const stream = cbor.encodeStream();
stream.on('data', chunk => {
  console.log(chunk);
});
stream.write({ key: 'value' });
stream.end();

Streaming Decoding

This feature supports streaming decoding, which is useful for processing large or continuous CBOR data streams. The example shows how to decode data from a stream.

const cbor = require('cbor');
const stream = cbor.decodeStream();
stream.on('data', obj => {
  console.log(obj);
});
stream.write(Buffer.from('a2616b65796576616c7565', 'hex'));
stream.end();
