How do I get Blaze templates to render an HTML string?

[Gregg Cooke]

I've found it very useful to have the old Spark engine render a template and pass me back the string of HTML, like so:

var reply = Template.confirmFeedback({
                name: name.split(' ')[0],
                email: addr });

I have a dozen examples of this technique littering my code now, and while there may be better ways to do the same thing, right now this is the one thing that stands in my way of switching over to Meteor 0.8.0 -- because Blaze doesn't seem to have a way to (a) output a rendered template as a string, and (b) forget about the variables that went into rendering the template.

How do I get this done using Blaze templates?  Is there another Handlebars-like template engine I can use?  How do the Meteor team expect people to use the templating engine to render HTML strings in v0.8.0+ (ie, what's the best method intended to be)?

Not 100% sure if this what you are looking for since I haven't tried it,

but this looks like what you are looking for:

Eric -- UI.renderWithData() won't work because what it produces is an object that can only be passed into UI.insert() to add to the DOM tree.  I played around with the idea of trying to add it to an element that's hidden, or to an isolated element, but there's still the issue that I do not want Blaze to treat these template's data reactively.

What I am working on now, and it does seem to work (though it forces me to violate the DRY principle) is the Meteorite package plain-handlebars, which is just the Handlebars library made safe for use within Meteor.  Still, the jury is out: I'm not yet convinced this is the better approach.

A few people have asked about this, so I'm putting the answer here: https://github.com/meteor/meteor/issues/2007
