Getting Viz.js

• Download from the releases page.

Building From Source

To build from source, first install the Emscripten SDK. You'll also need Node.js and Yarn.

Install the development dependencies using Yarn:

yarn install

The build process for Viz.js is split into two parts: building the Graphviz and Expat dependencies, and building the rendering script files and API.

make deps
make all

With docker

Create docker container to build:

./build_env.sh

Run the build with the continer:

./build.sh

Running Browser Tests

The browser tests can be run locally using Selenium WebDriver.

First, serve the project directory at http://localhost:8000.

python -m SimpleHTTPServer

Then, run tests using test-browser/runner.js. For example, to run test-browser/full.html in Chrome:

node test-browser/runner --file full.html --browser chrome
