How to generate a pdf whenever save the data? - html

Question

I need to generate a PDF whenever submitting the data from a html form. But PDF should not be a image of html page. I have used node.js for my server implementations. All the data that I have inserted from fields in the form should be included in the PDF. Also, I have used mongodb as my database.
var express=require('express');
var app=express();
var mongoose=require('mongoose');
var bodyparser=require('body-parser');
var outline=require('./schemas/outline');
var outcomes=require('./schemas/outcomes');
//making db connection
mongoose.connect('mongodb://127.0.0.1:27017/modulelist');
//checking db connection
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
console.log("connected to db");
});
//setting client location
app.use(express.static(__dirname+"/client"));
//setting body parser
app.use(bodyparser.json());
//Insert modulelist data to db
app.post('/SaveModuleList',function(req,res){
var mod=new outline(req.body);
mod.save(function(err,docs){
if(!err){
res.json(docs);
}else{
console.log(err);
}
})
});
app.post('/SaveOutcomesList',function(req,res){
var out=new outcomes(req.body);
out.save(function(err,docs){
if(!err){
res.json(docs);
}else{
console.log(err);
}
})
});
app.listen(3000,function(){
console.log("server runing in port 3000");
});
