Good afternoon to everyone, I am trying to organize my project, I prescribe to work with Ode, I have a function that creates a chart, I separated it into a separate file and exported this function so that I can use in my view. But he makes the following mistake:
File view.js
require('./modules/createGraphic')
File createGraphic
var createGraph = function createGraph(matrix, title, classHtml) {
var dimensao = []
var measure = []
dimensao = matrix.map((item) => { return item[0].qText })
measure = matrix.map((item) => { return item[1].qText })
var ctx = document.getElementsByClassName(classHtml)
var chartGrap = new Chart(ctx, {
type: 'line',
layout: {
padding: {
left: 0,
right: 0,
top: 0,
bottom: 0
}
},
data: {
labels: dimensao,
datasets: [{
label: 'taxa',
data: measure,
borderWidth: 5,
borderColor: ['rgba(75, 192, 192, 1)', 'rgba(192, 0, 0, 1)'],
backgroundColor: ['rgba(75, 192, 192, 0.2)', 'rgba(192, 0, 0, 0.2)'],
pointBackgroundColor:'#800b0b',
lineCap:'round'
}]
},
options: {
title: {
display: true,
text: title
}
}
})
}
module.exports = createGraph
The function is working. I did the tests and it worked out what catching you is this file.
Could you post the code snippet that is using this reference? You are using this function directly within a view?

require('./modules/createGraphic') require(["js/Qlik"], Function (Qlik) {
 var app = qlik.openApp('Recurso Humanos.qvf', config);
 app.getObject('filtro', 'zSmqYhK')
 app.getObject('kpi1', 'dRApjU')
 app.getObject('aoLongo', 'ebnCpu')
 app.getObject('kpi2', 'HuKkTX')
 app.getObject('kpi3', 'eJKBPu')
 app.getObject('kpi4', 'gbwRegu') app.getObject('barraSelecao', 'Currentselections')}) this is the snippet of the code q would be in the view, at the moment I do not want to show anything on the screen I would just like to get the modules to perform these functions of destintos files.

It’s still not very clear to me, but I suggest migrating this code snippet from the view to a controller. Within the controller perform the necessary processing and then pass the information (model) to view via the command:
res.render('minhaView', { dados: 123 });. If you still need to do some processing inside the view take a look at this link: https://medium.com/@Marcelo.vismari/nodejs-express-ejs-como-usar-funcoes-durante-renderizacao-f51122e1eaca– Marcelo Vismari
