Currently I am testing html-pdf module to generate pdfs from html. And I have successfully generated one. But the issue is that the text/data in the html is fixed at the moment.

What I am trying to do is have an html form on the front-end which the user fills and then generate a pdf which includes the content the user typed.

What I have done so far:

app.post('/pdf',function(req, res) {

  pdf.create(html, options).toFile('./businesscard.pdf', function(err, res) {
   if (err) return console.log(err);
     console.log(res);
   });

});

Is this possible using html-pdf? Any help will be greatly appreciated.

  • why not generate the pdf on the time of save click ? – CodingDefined Oct 06 '16 at 09:58
  • @CodingDefined Yes I could do that but still how would I pass the users data to the `pdf.create` which takes a `html` file as an argument to convert to pdf. Do you get what I mean? – Skywalker Oct 06 '16 at 10:00
  • Why not take a scree shot of the web page when the user click on save. Take a look at http://www.codingdefined.com/2016/01/capture-screen-of-web-pages-through-url.html – CodingDefined Oct 06 '16 at 10:16

Unfortunately, html-pdf module can't handle the dynamic data. You can take a look at the phantomjs which does the screen capture.

In fact, html-pdf module uses "phantomjs" at background. However, it uses the small feature of phantomjs.

You can check dynamic-html-pdf

Just follow the steps:

  1. Install using this command npm install dynamic-html-pdf --save

  2. Create html template

  3. Create pdf with below code:

    var fs = require('fs');
var pdf = require('dynamic-html-pdf');

var html = fs.readFileSync('template.html', 'utf8');

pdf.registerHelper('ifCond', function (v1, v2, options) {
if (v1 === v2) {
    return options.fn(this);
 }
 return options.inverse(this);
})

var options = {
 format: "A3",
 orientation: "portrait",
 border: "10mm"
};
 //Your dynamic data 
var users = [
 {
    name: 'aaa',
    age: 24,
    dob: '1/1/1991'
 },
 {
    name: 'bbb',
    age: 25,
    dob: '1/1/1995'
 },
 {
    name: 'ccc',
    age: 24,
    dob: '1/1/1994'
 }
];

var document = {
 type: 'buffer',     // 'file' or 'buffer'
 template: html,
 context: {
    users: users
 },
path: "./output.pdf"    // it is not required if type is buffer
};
 pdf.create(document, options)
 .then(res => {
    console.log(res)
 })
.catch(error => {
    console.error(error)
});

I was finding solution for the same and got around one.

https://medium.com/free-code-camp/how-to-generate-dynamic-pdfs-using-react-and-nodejs-eac9e9cb4dde

you can checkout this work around done in the blog. He simply called a function that returns an HTML string and he use backticks for dynamic data.
