We may do build jobs with Node.js API rather than shell commands.

Hmm... yeah, it needs to be run in the git-bash on Windows. Was Microsoft planning on releasing a Unix shell? I keep hearing things.

[saschanaz]

Microsoft provides Ubuntu environment on Windows 10 so users can use bash on it. It's not perfect for ReSpec though, as:

1. karma fails to run because the Ubuntu environment only has CLI
2. It's Ubuntu, so npm install wants to install the Ubuntu binary of Electron so that respec2html can only run on Ubuntu

So a Windows user currently have to use two shells to build and test (unless the user has git-bash).

@saschanaz, given your work on #1488, what else would now be needed here?

[saschanaz]

https://github.com/snyk/snyk/issues/48 remains, but now there is a simple workaround: npm run build:components which does not call snyk.

It's still a problem though.

https://github.com/snyk/snyk/pull/355 fixed this 👍
