title: Creating a pdf from a string with html content with NodeJS
body: <p>I need to create an api who will recieve a json with at least 3 strings, header, content of the file and the footer
  i've searched over the web for a library or an api who help me with that but everything i've found is or too simple or too expensive.
  i have already created the part who will recieve the json and the part who will send it (sending the file via base64 encoding) using an already downloaded pdf file</p>
  
  <p>but i need a library to create the pdf with the header and footer on every page.</p>
  
  <p>anyone has some experience doing this on nodejs?</p>
