PDF from HTML and Assets Directory

This guide will show the process of creating a simple PDF document from an HTML content organized in a directory using UniHTML.

Before you begin #

You should get your API key from your UniCloud account.

If this is your first time using UniPDF SDK, follow this guide to set up a local development environment. To set up a UniHTML server follow this getting started guide.

Clone the project repository #

In your terminal, clone the examples repository. It contains the Go code we will be using for this guide.

git clone [email protected]:unidoc/unihtml-examples.git

Navigate to the directory folder in the unihtml-examples directory.

cd unihtml-examples/directory

How it works #

The import section in lines 8-15 imports the necessary libraries. The init function defined in lines 17-24 sets the metered License API key to authenticate the library usage.

The main function is defined in lines 25-75. Line 32 in this function tries to create a connection with server by calling the Connect function from the unihtml package. The server address from the command line argument is provided to this function call. In line 38 a creator.Creator object is created. Line 41-42 creates a paragraph and draws it using Draw method the creator.Creator object. The HTML content is loaded from the data directory and rendered to PDF in lines 48-58. Line 64-65 creates additional final paragraph and draws it on the PDF document. Finally, the PDF document is written to a file in line 71 using c.WriteToFile("directory.pdf").

Run the code #

Run the code using the following command to generate the PDF file. Replace the server address with the actual address. E.g. localhost:8080 for a server running locally on port 8080.

go run directory.go <server address>
