wawoff2

woff2 for node.js (via WebAssembly)

Google's woff2 build for node.js, using WebAssembly. Why this is better than binary bindings:

• works everywhere without rebuild

Install

npm install wawoff2

Use Example

const require('wawoff2');

// src - Buffer or Uint8Array
wawoff.compress(src).then(out => {
  // store result
});

Command-line Example

To compress a .ttf file into a .woff2 file:

woff2_compress.js [-h] [-v] infile [outfile]

Positional arguments:
  infile         Input .ttf file
  outfile        Output .woff2 file (- for stdout)

Optional arguments:
  -h, --help     Show this help message and exit.
  -v, --version  Show program's version number and exit.

And the opposite, to decompress a .woff2 file into a .ttf one:

woff2_decompress.js [-h] [-v] infile [outfile]

Positional arguments:
  infile         Input .woff2 file
  outfile        Output .ttf file (- for stdout)

Optional arguments:
  -h, --help     Show this help message and exit.
  -v, --version  Show program's version number and exit.

Development

[Build emscripten]https://kripken.github.io/emscripten-site/docs/building_from_source/building_emscripten_from_source_using_the_sdk.html) latest sources. Pre-built versions generated bad code for some reasons.

• download emsdk and unpack to ~/emsdk-portable folder
• build latest version

cd ~/emsdk-portable
./emsdk update
./emsdk install sdk-incoming-64bit
./emsdk activate sdk-incoming-64bit

• Clone repo, update deps and rebuild if needed

git clone --recursive <path_to_repo>
cd wawoff2
source emsdk_env.sh
make clean all
