Document/Confirm Support for Web Workers

[dcramer]

Came up today in IRC. Pretty sure they work with XHR, but it'd be nice to know concretely.

yo @dcramer, I'd love some concreteness on this! Couldn't find it in the docs but some recent commits make me think this is being explicitly supported now?

@varenc we do support/work in webworkers now, as of #792. #855 was also related.

I'll make sure to add a mention of this to the docs before I close this issue.

[varenc]

thanks for the info! I wasn't sure... the docs here say that window.json needs to be defined for ravenjs which it isn't in a web worker. Should I also import something like json2.js to make it work? some testing show it's working despite this though I fear I'm not testing thoroughly enough.

[LewisJEllis]

That really just means to say "we need a JSON global variable", which webworkers do have; describing it as window.JSON is perhaps overly specific. Anything modern enough to have webworkers is modern enough to have JSON, so you should be fine.
