bison

A JSON to binary tool. This tool takes in JSON and converts it to a binary structure to save some bytes. This library is intended to serialize a JSON object similar to how you might expect with something like JSON.stringify.

Installing

npm i @jeffriggle/bison

Basic usage

const { encode, decode } = require('@jeffriggle/bison/cjs/index')

const jsonObject = {
    hello: 'World',
    num: 42,
    required: false
    nested: {
        foo: 'bar',
        arr: [42, 15, 'baz']
    }
}

const encoded = encode(jsonObject)
console.log(encoded) // binary structure.
const decoded = decode(encoded)
console.log(decoded) // original object.

Examples

Initial testing

All testing has been done on a local development machine, results may vary. To run the tests yourself use the npm run perf:nano through npm run perf:large commands provided by this package.

Encoding

Basic encoding in this case is using a very simple approach

const encoded = Buffer.from(JSON.stringify(obj))

Encode Type	Encode Size	Encode Time
Basic nano	12	0.168547
Bison nano	9	0.668347
Basic small	114	0.180368
Bison small	91	1.210133
Basic medium	501609	2.040591
Bison medium	473877	67.735946
Basic large	1003207	5.178138
Bison large	947742	133.127045

Decoding

Basic decoding in this case is using a very simple approach

const decoded = JSON.parse(buff.toString('utf8'))

Decode Type	Decode Time
Basic nano	65.414897
Bison nano	63.667062
Basic small	65.364427
Bison small	63.256234
Basic medium	160.526895
Bison medium	135.599895
Basic large	216.865982
Bison large	176.570844

Totals

Type	Total time delta	Size delta
nano	+1.248035	+3
small	+1.078428	+23
medium	-40.768355	+27732
large	-87.653769	+55465

Time differences are Basic - Bison (positive numbers are improvements)
