Development server not working

[jaylynch]

If I follow the instructions in CONTRIBUTING.md, I am unable to get the dev server to run, with any amount of prodding.

OSX 10.13.4, Node 10.10.0, nvm or system/Brew didn't seem to matter.

Playing around with config to try to get it to run or checking out an earlier version will sometimes provide ES module / Babel looking errors but checkout out current master and following the instructions provides:

Thanks for reporting, @jaylynch -- not sure what's going on exactly (I assume something to do with node 10), so for now I changed the example install step from npm i to npm ci and it seems to work. PR here, #67

Looks like that's done it, thanks! :)
