d8code

d8code

Encode binary data as a UTF-8 string that may compress efficiently.

It may be an interesting alternative to base64 and hex encoding to inline WebAssembly code in a Javascript module.

wasm-crypto

wasm-crypto mainly contains code. The data section is small.

	uncompressed	gzip -9	brotli -9
non encoded	230204	66807	56528
base64 encoded	306941	78534	72305
hex encoded	460408	73352	70044
d8 encoded	278523	72009	65816
d8 encoded, pshift=35	268758	71737	65212

libsodium

libsodium mainly contains optimized code. The data section is small.

	uncompressed	gzip -9	brotli -9
original	142651	73847	67085
base64 encoded	190205	91460	83944
hex encoded	285302	84001	75940
d8 encoded	183114	82821	71612

tanks

The Tanks game contains code, but also a solid amount of already compressed binary data.

Base64 encoding performs the best here, even though any kind of encoding should be avoided here.

	uncompressed	gzip -9	brotli -9
original	3773944	3751303	67085
base64 encoded	5031929	3796237	3765105
hex encoded	7547888	4252953	4090581
d8 encoded	6162834	4648197	4108294
