var handlebars = require('handlebars');

var HandlebarsIntl = require('handlebars-intl');
HandlebarsIntl.registerWith(handlebars);

I can see how to add helpers when using jsreport studio. What I am not sure about is how I could use this with jsreport-core ... would the fragment above go before the init()? after? I tried a few variations, but none of them made the helpers available within the template.

Any pointers would be greatly welcomed.

Thanks!

var jsreport = require('jsreport-core')({
   tasks: {
       allowedModules: ['handlebars-intl']
   }
})

jsreport.init().then(function () {     
   return jsreport.render({
	   template: {
		  content: '{{formatNumber 10}}',
		  engine: 'handlebars',
                  recipe: 'html',
                  helpers: `var HandlebarsIntl = require('handlebars-intl');
                   HandlebarsIntl.registerWith(handlebars); `
	   }
	}).then(function(resp) {	
     console.log(resp.content.toString())
   });
}).catch(function(e) {
  console.log(e)
})

More generally, is there access to the handlebars object so I can work more directly with partials, and write more sophisticated helpers that are in my own separate module etc?

Thanks again for your prompt and helpful response!

The trouble here is that by default jsreport runs the templating engines isolated in the extra process. So we cannot expose handlebars object to you. It would work only if you use tasks.strategy='in-process'... I think we should be able to expose the handlebars instance in this case and make it easier for jsreport-core devs to extend it. I will discuss it with @bjrmatos .

Thanks!
