A Better Solution to create PDF with Rotativa and ASP.NET MVC

In most of the line of business application we need some kind of reports. Now days we need those reports as PDF format as it is the most convenient way of storing documents. I have written a post about creating a PDF in ASP.NET MVC with Razor PDF and it is one of the top visited page on my blog.

Creating PDF with ASP.NET MVC and RazorPDF

But now I have found a better way to create a PDF with ASP.NET MVC so I thought it will be a good idea to write a blog post about it. So in this blog post we are going to learn about creating PDF with ASP.NET MVC with the use of Rotativa as open source framework for creating PDF with ASP.NET MVC.

What is Rotativa:


It is a framework created by Giorgio Bozio with the purpose of creating PDF in ASP.NET MVC extremely easy way. It is based on wkhtmltopdf tool to create PDF from html content rendered on browser. It uses the web kit engine which is used by Safari and Chrome browser to render html. And support most of HTML tags and styles. It is a open source command line tools so Giogio has created a nuget package to use this tool as PDF creator. You can find more information about Rotativa from the following links.

You can find source code of rotativa-

https://github.com/webgio/Rotativa

Now let's create example to demonstrate the power of Rotativa with ASP.NET MVC

Creating PDF with ASP.NET MVC and Rotativa:


So to create example, I have created a ASP.NET MVC application.

asp-net-mvc-pdf-application

The first thing we need to do is to add Rotativa Nuget Package in our application.

nuget-package-for-rotativ-asp-net-pdf
Here is the model class I have used to demonstrate power or Rotativa.
namespace MvcPdf.Models
{
    public class Customer
    {
        public int CustomerId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string ProfileImage { get; set; }
    }
}
In this example, we are not going to use any database so we are going to hardcode data in customer. so We have done is hardcode list of customer in controller and returning it to a view.
using MvcPdf.Models;
using Rotativa;
using System.Collections.Generic;
using System.Web.Mvc;

namespace MvcPdf.Controllers
{
    public class CustomerController : Controller
    {
        private List<Customer> _customers;

        public CustomerController()
        {
            var imagePath = "profile.jpg";
            _customers = new List<Customer>()
            {
                new Customer {CustomerId = 1, FirstName = "Jalpesh",
                               LastName = "Vadgama", ProfileImage = imagePath},
                new Customer {CustomerId = 1, FirstName = "Vishal", 
                               LastName = "Vadgama", ProfileImage = imagePath}
            };
        }

        // GET: Customer
        [HttpGet]
        public ActionResult Index()
        {
            return View(_customers);

        }
    }
}
And in view we has displayed this list as table like following.
@model List<MvcPdf.Models.Customer>

@{
    ViewBag.Title = "PDF Title";
  
}

<h2>Convert to  PDF</h2>

<table class="table">
    <tr>
        <td class="alert-success">First Name</td>
        <td class="alert-info">Last name</td>
        <td style="background-color: yellow;">Profile Image</td>
    </tr>
    @foreach (var item in Model)
    {
        <tr>
            <td>@item.FirstName</td>

            <td>@item.LastName</td>
            <td><img src="@Url.Content("~/content/" + Path.GetFileName(item.ProfileImage))" alt="" width="100" height="100" /></td>
        </tr>
    }

</table>    
          
@Html.ActionLink("Print", "Print", "Customer")
If you see in above code, I have used a image to display profile pic. I have also used different styles for td element in table to display power of Rotativa. Even I have used hardcoded style directly.  At bottom I have created  Html Action link to print this view as PDF and following is a code the printing this view as PDF in Action Result.
public ActionResult Print()
{
    return new ActionAsPdf("Index", _customers);
}
And when we run this application it looks like following.

browser-demo-pdf

Now when you click on Print it will create a PDF like following.

pdf-created-with-rotativa-with-browser

This was pretty basic demo but there are lots of options also available with Rotativa you can find that options in documentation on Github as well. I have shared same link above.
You can find source code of this sample application on github at following location - https://github.com/dotnetjalps/AspNetMvcPdfRotativa
Hope you like it. Stay tuned for more!!

Why it's the right time to learn TypeScript.

In Today's world, If you are an web developer and you don't know JavaScript then you will feel left behind. It's never been a good time to be a JavaScript developer than now. With the rise of Node.js  JavaScript is everywhere now. But as you know when Size and Complexity of your JavaScript is Increased it's very difficult to maintain and mange. That's where TypeScript comes into picture. It is a life saver some times. So in this blog post we will see Why It's the right time to learn TypeScript.

What is TypeScript?


TypeScript is a free and open sourced programming language developed and Maintained by Microsoft. It works as a super set of JavaScript. As we all know that JavaScript is very liberal language by nature. So that we tend to make more mistakes and we does not know all the errors at run time. TypeScript is a strict super set of JavaScript so that you can get most of errors at compile time only.  As per official website of TypeScript it's a language that lets you write JavaScript in the way you really want to. TypeScript offers all the features that you need for Object oriented programming. You can find more information about TypeScript on it's official web site on below link.

http://www.typescriptlang.org/

ECMAScript and TypeScript:


ECMAScript is the specification standard of the JavaScript. So right not standard stable version if ECMAScript 5 and some of the browsers support ECMAScript 6. ECMAScript 6 features are being adopted by latest browsers.While TypeScript follows most of syntax of ECMAScript 6 so that you don't have a feel of the learning new language. As per official road map of Typescript 1.6 comes with ES6 Generator so you can convert your script code into ECMAScript6. Your can find more about that on following blog post.

http://blogs.msdn.com/b/typescript/archive/2015/09/16/announcing-typescript-1-6.aspx

TypeScript is everywhere:


As we know TypeScript is a fully Object Oriented language, It's provide great productivity boosts than JavaScript and it's super set of JavaScript so it will be compiled into JavaScript itself. So because of this lots of great framework started using TypeScript like following.
  1. Angular JS
  2. Iconic Framework for creating frond end mobile App
  3. Native Script from Telerik is also completely written TypeScript itself.
Take a example of AngularJs, It is one of the most popular JavaScript Framework on earth. With Angular.js 2.0 it will be fully written with TypeScript.

Tooling:


Most of Web Development editor whether it's paid or free are having TypeScript tooling.  Most popular editors like Visual Studio, Visual Studio Code, WebStorm, Atom, Sublime text and Eclipse are having great tooling for TypeScript.

Why to use TypeScript:


Followings are reason why we should use TypeScript instead of JavaScript.
  1. Fully Object Oriented support with classes and interfaces. So It's a great productivity boost for any developer and easily maintainable and understandable.
  2. It's provide most of the errors compile time while JavaScript is more liberal than this. So less run time error means less bugs for your application.
  3. Refactoring is very easy in TypeScript compare to JavaScript.
So it's never been late. It is the right time to learn TypeScript. Hope you like it. Stay tuned for more!.
