Why developers can't say no to Node Getting to Know NODE – A look at ruthenpress.info, the server side framework that continues to gain popularity The post Why.

Render pdf in a remote server jsreport is an innovative reporting platform developed in node. It can be used in various use cases from simple one like html to pdf conversion. To more advanced where jsreport is used as a reporting server for designing and printing reports remotely. This article covers some of the scenarios where jsreport can be usefull. Rendering pdf jsreport makes it super simple to print html into pdf using chrome. You just need to install jsreport npm package and call one function. Paper size, headers and footers You can also submit various other options to rendering like paper size, paper margin, header and others. You can find more information about jsreport and chrome integration here. Following example will print pdf with a width of px and a header. Dynamic pdf rendering jsreport evaluates javascript templating engines in submitted html. This means you don't have to render html dynamically on your own and let the hard work to be done by jsreport. JavaScript templaing engine can be specified in the overloaded render function. Currently it supports jsrender and handlebars by default.

In order to make use of these, you need to install Node. Instead of repeating the process here, I kindly ask you to visit the official installation page. Please come back once you are up and running. Ok, let's just jump in the cold water and write our first Node. Open your favorite editor and create a file called helloworld.

Ok, this stuff is boring, right? Let's write some real stuff. Fair enough. Now, you could achieve this goal by googling and hacking together something.

But that's not what we want to do here. Furthermore, we don't want to write only the most basic code to achieve the goal, however elegant and correct this code might be. We will intentionally add more abstraction than necessary in order to get a feeling for building more complex Node. Let's dissect our application. Which parts need to be implemented in order to fulfill the use cases?

Let's think a moment about how we would build this stack with PHP. Which in turn means that the whole "we need to be able to serve web pages and receive HTTP requests" stuff doesn't happen within PHP itself.

Well, with node, things are a bit different. Because with Node. In fact, our web application and its web server are basically the same. This might sound like a lot of work, but we will see in a moment that with Node. Let's just start at the beginning and implement the first part of our stack, the HTTP server. When I arrived at the point where I wanted to start with my first "real" Node.

Do I need to have everything in one file? What if I want to make sure that my code stays readable the more stuff I implement? Turns out, it's relatively easy to keep the different concerns of your code separated, by putting them in modules. This allows you to have a clean main file, which you execute with Node. So, let's create a main file which we use to start our application, and a module file where our HTTP server code lives. My impression is that it's more or less a standard to name your main file index.

It makes sense to put our server module into a file named server. Let's start with the server module. Create the file server. That's it! You just wrote a working HTTP server. Let's prove it by running and testing it. First, execute your script with Node. Now, open your browser and point it at http: This should display a web page that says "Hello World".

That's quite interesting, isn't it. How about talking about what's going on here and leaving the question of how to organize our project for later? I promise we'll get back to it. The first line require s the http module that ships with Node. We then call one of the functions the http module offers: This function returns an object, and this object has a method named listen , and takes a numeric value which indicates the port number our HTTP server is going to listen on.

Please ignore for a second the function definition that follows the opening bracket of http. We could have written the code that starts our server and makes it listen at port like this:. Thus, Node. In order to make use of these, you need to install Node.

Instead of repeating the process here, I kindly ask you to visit the official installation page. Please come back once you are up and running. Open your favorite editor and create a file called helloworld.

Ok, this stuff is boring, right?

Let's write some real stuff. A full blown web application with Node. Now, you could achieve this goal by googling and hacking together something. But that's not what we want to do here. Furthermore, we don't want to write only the most basic code to achieve the goal, however elegant and correct this code might be. We will intentionally add more abstraction than necessary in order to get a feeling for building more complex Node. The application stack Let's dissect our application.

Which parts need to be implemented in order to fulfill the use cases? We want to serve web pages, therefore we need an HTTP server Our server will need to answer differently to requests, depending on which URL the request was asking for, thus we need some kind of router in order to map requests to request handlers To fulfill the requests that arrived at the server and have been routed using the router, we need actual request handlers The router probably should also treat any incoming POST data and give it to the request handlers in a convenient form, thus we need request data handling We not only want to handle requests for URLs, we also want to display content when these URLs are requested, which means we need some kind of view logic the request handlers can use in order to send content to the user's browser Last but not least, the user will be able to upload images, so we are going to need some kind of upload handling which takes care of the details Let's think a moment about how we would build this stack with PHP.

Which in turn means that the whole "we need to be able to serve web pages and receive HTTP requests" stuff doesn't happen within PHP itself.
