Rendering Current Page With PhantomJS - node.js

Question

I am building an analytics dashboard using the MERN stack (Express, Node) are the Important things to highlight.
As part of a dash view, I was trying to find if it's possible to trigger a PhantomJS call to create a pdf report using a button on the page itself.
Given you need to be logged in to see your own analytics, I can not just run phantom from the command line and pass it in the URL of one of the dashboard pages since it requires a login and queries to be made.
Is it possible to do this with phantomJS?

Answer 1

If I correctly understood your question.
Example:
[main.js]
const dashboardToPdfCtrl = require("./controllers/phantom/pdf");
router.route("/api/dashboard/phantom").post(dashboardToPdfCtrl.createPdf);
router.route("/api/dashboard/phantom/html")
.post(dashboardToPdfCtrl.createDashboard);
When the user clicks on the "button" you can validate the USER according to the architecture of your application.
[pdf.js]
exports.createPdf= async (req, res) => {
if (!req.user || !req.user.sub) {
return res
.status(401)
.send({ message: 'No authorization token was found' });
}
const instance = await phantom.create();
const page = await instance.createPage();
const settings = {
operation: "POST",
encoding: "utf8",
headers: {
"Content-Type": "application/json"
},
data: JSON.stringify({
user: req.body.userId,
anyDataYouNeedToRender: req.body.anyDataYouNeedToRender
})
};
//POST request to /api/dashboard/phantom/html
await page.open(
`${process.env.HOST}:${
process.env.PORT
}/api/dashboard/phantom/html`,
settings
);
//Save the content of /public/dashboard/dashboard.html with received data to pdf
const pageSaved = await page.render(
path.resolve(`./public/dashboard/file.pdf`)
);
if (pageSaved) await instance.exit();
}
exports.createDashboard = (req, res) => {
res.render(
path.resolve("./public/dashboard/dashboard.html"),
{ user: req.body.user,
anyDataYouNeedToRender: req.body:anyDataYouNeedToRender
}
);
};
