jsreport 2.0 BeforeRender Not Working - handlebars.js

Question

I am working on jsreport v2.0 and wants to render the data for the report. I am using handlebars and phantom-pdf and my beforeRender function is not getting called by default.
For jsreport v2.0, i have added the listener for the beforeRender as following but still it did not seem to be called by default to render the data.
function beforeRenderListeners1(req,res){
console.log("Listener Called");
}
const jsreport = require('jsreport-core')({
})
jsreport.beforeRenderListeners.add('beforeRenderListeners1', (req, res) => {
console.log("hello");
req.data.check = abc();
})

Answer 1

since i don't know the complete code that you are using i will go ahead and provide you a snippet that works in latest jsreport-core v2 (2.0.3) with node 8
const jsreport = require('jsreport-core')()
jsreport.use(require('jsreport-handlebars')())
jsreport.beforeRenderListeners.add('beforeRenderListeners1', (req, res) => {
console.log("before render called")
req.data = req.data || {}
req.data.check = 'check pass'
})
jsreport.init().then(() => {
console.log('started')
return jsreport.render({
template: {
content: '<p>sample demo content, check: {{check}}</p>',
engine: 'handlebars',
recipe: 'html'
}
})
}).then((res) => {
console.log('render done')
console.log(res.content.toString())
}).catch((err) => console.error(err))
put that in a file and then run it, you will see the message before render called being printed in console.
