hdt-wasm

Wasm port of the hdt-cpp library to allow indexing graph databases on the browser.

Status

The project is nowhere close to a production-ready build with a stable api. Yet, it is already able to compile with no major issue and run some demos!

Check the demos here:

• a turtle (ttl) to HDT converter: https://lucafabbian.github.io/hdt-wasm/demo-converter/dist
• a sparql query over HDT playground: https://lucafabbian.github.io/hdt-wasm/demo-sparql/dist

Getting started

With Docker

You find a Dockerfile with all dependencies already preconfigured. Just build it and run it with:

docker build -t hdt_emscripten .
docker run --rm -v $(pwd):/src -u $(id -u):$(id -g) hdt_emscripten bash build.sh

Without Docker

(tested on Ubuntu 22.04)

Be sure to have Node.js and emscripten on your system (test with em++ --version). Do not use the ones from Ubuntu repos, they are outdated.

You also need the following dependencies:

sudo apt-get install git autoconf libtool pkg-config

Build with:

# clone deps, rebuild and link them 
./build.sh

What's next?

The main goal now is to provide a real binding to the WebAssembly file and distribute it as a npm package.

License and authors
