[WIP] Precompile Handlebars templates

[svizzari]

🐨 🚫 ⚠️

POC/WIP to precompile Handlebars templates on the server rather than in the client.

Note: this currently only services ZAT, ZAM would need to be independently updated if proceeding

/cc @danielbreves

Tasks

• Investigate rendering out precompiled templates to a file, caching that file as an app asset
• Investigate using handlebars.rb rather than execjs
• Investigate correct function of custom Handlebars helpers
• Investigate using Bower/NPM to pull in the Handlebars dependency
• Update tests

Risks

• [HIGH] Templates not rendering as expected

I had to do the following to make it work:
That also what the normal compiler outputs btw (it wraps it into that Handlebars.template function).

-  <%= name %>: <%= fn %>,
+  <%= name %>: Handlebars.template(<%= fn %>),

I can't make a PR on this PR... so I guess I'll just comment here ;-)

Hey @ocke, yep

I only began testing when I first put it up, realised there was a call missing, then moved onto something else 😸

Thanks for the comment, much appreciated

Well now you know I tried your code ;-). I actually programmed this thing myself, not realizing you did it already.

I used npm and .bin/handlebars #{file} though. But I like your approach more.

You probably saw, in the PR description, I considered that, as an enhancement, it might be better to precompile the templates out to a file to be cached in S3, rather than precompiling every time.
