Usage and testing

Node.js

Even the fact we provide a tiny wrapper around the main functionalities of harfbuzz, it's easy to use other parts see example/nohbjs.js to see how, but you may need a custom build.

npm

Can be added with npm i harfbuzzjs or yarn add harfbuzzjs, see the examples for how to use it.

Need more of the library?

File a bug and mention your usecase.

Use the library in a bigger emscripten project?

See harfbuzz port inside emscripten and emscripten-ports/HarfBuzz, basically all you need is to use -s USE_HARFBUZZ=1 in your build.

binaryen

Optionally you can install binaryen and use wasm-opt like:

wasm-opt -Oz hb.wasm -o hb.wasm

binaryen also provides wasm-dis which can be used for,

wasm-dis hb.wasm | grep export
wasm-dis hb.wasm | grep import

with that you can check if the built wasm file only exports things you need and doesn't need to import anything, as usual with wasm files built here.
