I am trying to make common templates that used both by Rails and the client side, ie in coffescript.
I use hogan_assets and haml_assets to export templates to JS. However I can't find a way to use HAML and Mustache to render server-side views.
Partial solution is described here, but it doesn't work with view helpers, ie, "render partial" doesn't work.
For some unknown reason chaining of handlers, such as .mustache.haml, doesn't work, and I can't find neither good info on Rails template handler nor an example on how to build "chainable" handler.
I've been experimenting with something like smt_rails lately, but I have yet to find a silver bullet.

I have surfed a couple of hours through the web but couldn't find any articles/walkthroughs/comparisons touching erb integration of webpacker. I've found 1 question, unfortunately, the author haven't read docs attentively and the answer was right there, so - no any additional info there.
I have seen plenty of articles about vue and react, but nobody says a word about erb. However, it's quite clear why using react/vue/else similiar, it is not with erb.
The theme is quite vast and I expect a little hate towards me, so I'd ask two related questions (but if you have something to tell more about it - that's appreciated).
As I understand - it's vanilla (plain) js (maybe with a flavour of jQuery) caring just about dom and styling, with all the preprocessing made by rails. If it is so why not just continue using sprockets?
And what are the reasons to choose it instead of some react/vue/else framework?
You may use both : a vanilla JS framework (React, Vue ...) and some erb files. I find it interesting to setup my constant and other configuration variables within a .js.erb file that is generated by my Rails app when building the js app.
Things I like to put in this erb files :
schemas of my api, generated by my serializers
constants, like enum
values to be used in forms
To generalize, you can put anything owned by the backend that will not change at run time
this save you a couple API calls to retrieve this data. However, I tend to stop doing this as your JS app and Rails become tightly coupled and you can't use the sources of your JS app outside the Rails app
I asked a specific question about problems I'm having with a specific gem intended to do this in a separate thread ( https://stackoverflow.com/q/18577033/1206117?sem=2 )
But I feel I may be on the "wrong boat" somehow because all of the questions I find about Rails/Haml/JST-templates are at least 2 years old, or go unanswered.
I'm writing an app with a lot of client-side JS and so want to use templates to render views (I'm using Backbone). I want to use Haml to write the templates.
I'm not looking for a debate about which gem/method is better, I'm looking for A WAY that works and has current support and active use. At present I cannot write my JS templates in Haml, and it's a bummer. I'm avoiding CoffeeScript at present since I'm still rather new to Javascript.
I've submitted an issue to the haml git repo.
https://github.com/haml/haml/issues/716
Looks like https://github.com/netzpirat/haml_coffee_assets gives you what you want. (window.JST templates, written in HAML, with inline coffescript support)
Is this possible? I know people use mustache to share templates, but can you use HAML? I would prefer pre compilation.
A quick google search turns up this lib for client-side rendering of HAML . So it would appear that yes, you could share templates between the client-side and server-side of your app.
If you are processing your JS templates server-side first, then the asset pipeline will take care of this with the correct file extension. You wont be able to use the rendered haml template on the client-side though as it will be missing its tags..
I'm working with a large project where the templates are written in erb. We're getting more and more into client side rendering of parts of the project and we have lots of exact duplicates in mustache of our erb templates.
I'd like to change the erb templates that are replicated in mustache to mustache and print the js templates out from those templates.
I haven't been able to figure out how to mix templating languages in rails though, is this possible? I'd rather not rewrite all the erb templates in mustache.
Thanks!
Maybe Isotope could be useful for you? I never tried it though.
I fear you'd have no direct solution...
An alternative:
You could reuse your good old html created by ruby if you insert in handlebars templates. But it's another js library...

I have metal working (thanks to Railscasts), but I have a haml template that I want to render instead of just plain text. Apparently you can render ERB , but I don't see any place to do the same with haml. Is it possible or will I just have to live with using the plain rails routing if I want to continue using haml?
Thanks!
Haml, like ERB, has a Ruby interface. However, also like ERB, using it without setting up the proper template caching (as Rails normally does for you) will make it very slow, almost certainly slower than Rails' routing. So be careful, and use #def_method rather than #render.
