This causes many problems regarding usability, accessibility, SEO and so on. However, there are some cases in which PDF files are required: when a document needs to be archived and must be used outside the web for example an invoice or when you need a deep control on printing. It was just the need to control printing that brought me to research a way to easily generate a PDF. The purpose of this article is not to simply explain how a PDF can be created there are many easy way to do thisbut also to focus on the circumstances where a PDF file can solve a problemand how a simple tool like jsPDF can help with this.

Anyone who has dealt with CSS printing rules knows how difficult it is to achieve a decent level of cross-browser compatibility take a look, for example, at the Page-break support table at Can I Use.

My goal is to have complete control over the positioning and size of elements, page breaks and so on. Unfortunately, the library seems to be abandoned its last version dates back to Update: actually, the latest version appears to be from Decemberbut thanks to some JavaScript libraries, we now have the ability to build PDF files directly in the clients thus making their generation faster.

Angular2+ jsPDF and html2canvas File Generation

The jsPDF documentation is fairly minimal, consisting of a single page along with some demosand a little more information in the source file or in its jsDoc pagesso keep in mind that using it for complex projects can be a little hard in the beginning.

First you have to link to the jsPDF library in this case, from cdnjs. Some months ago, I was asked to build an application for creating some simple flyers. It was part of a larger project that dealt with some services for travel agencies, and the real flyer was partially populated by some JSON data. A functioning demo is available at the end of this article or directly in CodePen. Note that, since CodePen loads the result page in an iframe, the PDF preview — which is loaded in an iframe too — has some issues with Chrome and Safari that prevent the preview from being displayed.

Use Firefox if you can, or try the demo on my personal site. The user interface allows the user to insert some basic data a title, an abstract and a price.

Optionally, an image can be added, otherwise a grey-boxed Special Offer title is displayed. Images are added using the addImage function. Note that every object placed in the PDF page must be exactly positioned.

You have to take care of the coordinates of each object using the units declared. The title is added using the textAlign function. Note that this function is not part of the jsPDF core, but, as suggested by the author in his examples, the library can be easily expanded using its API. You can find the textAlign function at the top of flyer builder script:. This function calculates the X coordinate of the the text string to make it centered, and then calls the native text method:.

The Special offer grey box and the price circle use two similar methods: roundedRect and circle. Both of them require top-left coordinates, size values the width and height in the first case and the radius in the second one :. The style parameters refers to the fill and stroke properties of the object. Its use could be easy, but the lack of a complete documentation makes every step really complicated. But ultimately, I think the only really definitive solution can be better browser support for printing CSS rules!

We will describe the process of generating PDF documents using our sample application attached to this article. We will go through examples and discuss all the used methods. The sample application consists of just few buttons, where clicking each button generates a different PDF file. We've created few helper methods that will deal with the process of responding to the user actions and saving files on the device.

Let's examine them. This function will be invoked after clicking the button. The function takes an example number as the only parameter. If the user forgets to pass the file name or click cancel, then we stop executing the function.

If the file name does not contain the. The second parameter is a callback function that will be executed when the process of resolving the directory is finished.

Now, we have to fill our file with the data. The second parameter is a callback function that will be executed after the stream is opened. We pass an example number as the first parameter. Later we wrap the ArrayBuffer with the Uint8Array view. We have to create that view, so that the buffer will be interpreted as individual bytes.

Having the PDF file data as Uint8Array, we loop over that buffer and write each chunk into the stream. We have to convert chunks to simple Arrays because it's the only accepted format by the writeBytes method of the stream object. As parameters we pass the page, width and height in the units defined in the document constructor. Adding pages moves us to this page, so any operation will be executed on that page.

You can run the application to check it out and investigate the application's code that is attached to the article. The first two are X and Y positions of the text in units defined in the document constructor. Notice that the Y position, is the position of the text baseline, so printing something with the Y position set to 0 will actually print it over the top edge of the document.

The third argument is the text to be displayed. The second thing is the font name used to draw the text. We can choose one of the following: courierhelveticatime. Next thing is the font size. The last thing is the text color. The sample document showing different ways of displaying text is located under Example 2 in the sample application attached to the article.But in some situations, we have rich UI elements like images and data representation in graphs, so in that case, we may require PDF as it is.

See working demo here. Each selector or ID will be converted into. Using addPage function we are setting height and width of new PDF page. We can adjust it dynamically or as per application requirements. In setTimeout we have added code to create download link and iFrame if we want to show PDF created in and in page iFrame.

Which we will add in next step. Let me know in the comments section if you face any issue in plugin this code sample into your app or if you have any suggestion always welcome. Is there a way to set the location where the pdf has to be downloaded, coz i need it to be emailed.
