Make version (etc.,) accessible from api

[tomzemp]

Need to know which version of app is deployed, e.g. on https://test.ohie.datim.org/mAtches/, so we can make this information available, with api being useful

possible items:

• version #
• date updated
• github commit (this might deviate if build is from non-committed version)
• developer name/contact

Could also incorporate simplified display on front-end from UI in Settings button

Hi @vshioshvili

I've added in an api/about to mAtches app with some basic information: {"appName":"mAtches","version":"1.0.1","buildDate":"2020-09-04T12:18:22.173Z","repository":{"type":"git","url":"https://github.com/pepfar-datim/mAtches"}}

I'm just pulling this information (server-side) from the package.json file (https://github.com/pepfar-datim/mAtches/blob/master/queries.js#L8)

I think this is okay security wise as I don't see any way for the contents of package.json to become more generally available client side, but let me know if you disagree.

I've looked around a bit at some other options for versioning:

• Automatically updating version when running a new build seems achievable and there are some packages for that.
• Updating build time automatically seems surprisingly less popular as an idea, though it seems like it may be possible to configure webpack to make that information available from the client-side (though I don't know if that's particularly useful unless we're making this information available in the UI). Probably just amending the build script with a basic script to update this (either in package.json or elsewhere) is the way to go.
• I can look into incorporating the most recent git commit from the repo, though it's possible to build from non-committed code, so maybe just having the build time would be better.

Vlad and I discussed/clarified on April 19 that primary goal is to include/update the commit hash on build. I think we can handle this most easily by modifying the build script to update package.json (and should also update the build time). We can then expose the commit hash through the api similar to version number

@vshioshvili: I've modified the build to pull the latest commit:

I think this is what you envisioned (so closing the ticket), but let me know if you want something else
