[joseespinozac]

I would love a more detailed example on how to use or declare the dataset in the report JSON

let report = {
        report: 'usersreport',
        data: {
            name: 'Joe'
        },
        dataset: jasper.toJsonDataSource({  how to send this, and how I need to build my jrxml to use the dataser I declare here
            name: 'Joe',
            hola: 'mundo'
        },'data')
    };

Sorry for my english
And please tell me if I can send arrays? and how to do it

[dcsline]

look in my tested content for sample js:
var fs = require('fs');

var jasper = require('node-jasper')({
path: '../lib/jasperreports-5.6.0',
reports: {
stock_ofertas: {
jasper: __dirname + '/sample.jasper',
jrxml: __dirname + '/sample.jrxml',
conn: 'in_memory_json'
}
}
});

jasper.ready(function() {
var r = jasper.export(
{
report: 'stock_ofertas',
data: {
language: 'spanish',
// on jasper make a parameter named "dataset2" and use on a subreport:
// ((net.sf.jasperreports.engine.data.JsonDataSource)$P{dataset2})
dataset2: jasper.toJsonDataSource(
{
dados: [{ value: 1, value: 2 }]
},
'dados'
)
},
dataset: [
{
name: 'Gonzalo',
lastname: 'Vinas' // TODO: check on UTF-8
},
{
name: 'Agustin',
lastname: 'Moyano'
}
]
},
'pdf'
);

//fs.writeFile(__dirname + '/sample.pdf', r);
fs.writeFile(__dirname+ '/sample.pdf', r, (error)=>{
    if(error) console.log(error);
})

});

Why you want build an json from an array? If you want do this, then look for tools which are build the json from an array.
