Using viz.js distribution in WebWorker together with require.js

[mstefaniuk]

I'm developing an online Graphviz dot editor and I'm using old version of viz.js. I made a common module adding define wrapper around distribution code and I embedded it in WebWorker with use of require() as described in its guideline.

Now I'm trying to upgrade to newer version but I have problems to use it in the same way. I'm receiving errors from initializing my module depending on viz.js. As far I understand (from generated code) there is support for WebWorker environment and require.js also. I'm not sure if it is supporting both together. If yes please give me an advice how to do that.

The wrapper code for Viz.js used to reference the window object, so it couldn't directly be used in a Web Worker. I've changed this in the most recent version. Have a look at the gh-pages branch for an example: https://github.com/mdaines/viz.js/tree/gh-pages

@mdaines In your example viz.js is included into WebWorker with importScripts(). My question was how to do it the same with use of require.js.

In that case, I don't know. I assume you'll have to either add the define wrapper yourself or use a shim: http://requirejs.org/docs/api.html#config-shim
