Is it possible to include expressions in partials parameters? I am trying to achieve something similar to this:
{{> myPartial greeting=(i18n.greeting + "my text") }}

If you take a look at the subexpressions section of the Handlebars documentation, you'll find a helpful explanation on how to pass the results of an inner helper as an argument to outer helpers. This is achieved by using the following syntax:
{{> myPartial greeting=(i18n 'greeting') }}
It seems like you might be attempting to combine multiple string values into a single parameter called greeting for your partial. In order to accomplish this, you will need to create or import a helper that can concatenate strings and then apply this helper as another subexpression. Here's what the modified syntax would look like:
{{> myPartial greeting=(concat (i18n greeting) 'my text') }}
To implement the necessary concat helper, you can define it as shown below:
Handlebars.registerHelper('concat', function () {
return Array.prototype.slice.call(arguments, 0, -1).join('');
});
To determine the server options in nodeJS, it all comes down to how you configure them. In my case, I set up the functions in res.locals using a '__' expression with Version Express Over 4.0. Here's an example:
{{> myPartial greeting=(i18n 'greeting')}}
Your JSON file in locales needs to have this specific key to work its magic...
Also, if you want to combine your key with any string, do it like this:
{{> myPartial greeting=(i18n 'Hello %s', 'Marcus')}}
I hope you find this information helpful.
