PDF Invoice Template

To fix Angular v13 and some NodeJs issues, I've separated into two different npm packages, as below:

For web browsers: npm i jspdf-invoice-template

For NodeJs: npm i jspdf-invoice-template-nodejs

PDF template created to generate invoices based on props object. Using jsPDF library. ( jsPDF is exported also, so it can be used without importing jsPDF separately. )

All this code works by using an object as parameter for the function. From v1.3.1 all properties are optional and you can add them as empty string or just remove them from the prop object, if you want to display nothing. Also it can be used in different languages because all labels (and all text) can be set in the props object.

Install and usage

Get it from NPM:

npm i jspdf-invoice-template

Or for NodeJs:

npm i jspdf-invoice-template-nodejs

Alternatively, load latest version from a CDN: (Recommended to use a static version (not @latest) to prevent failure when updates are made)

<script src="https://unpkg.com/[email protected]/dist/index.js"></script>

Usage

You're ready to start creating your invoice PDF document:

//by importing 
import jsPDFInvoiceTemplate from "jspdf-invoice-template";

//or directly in browser
jsPDFInvoiceTemplate.default( propsObject );


//you can either import the `OutputType` const or `jsPDF` class if you want to create another PDF from scratch (without using the template) 
import jsPDFInvoiceTemplate, { OutputType, jsPDF } from "jspdf-invoice-template";

//or directly in browser
const outputTypes = jsPDFInvoiceTemplate.OutputType;
const jsPDF = jsPDFInvoiceTemplate.jsPDF();

jsPDFInvoiceTemplate.default( propsObject );

Parameters object

Just edit the props object and call the function, nothing more... 😊

const pdfObject = jsPDFInvoiceTemplate(props); //returns number of pages created

//or in browser
var pdfObject = jsPDFInvoiceTemplate.default(props); //returns number of pages created

var props = {
    outputType: OutputType.Save,
    onJsPDFDocCreation?: (jsPDFDoc: jsPDF) => void, //Allows for additional configuration prior to writing among others, adds support for different languages and symbols
    returnJsPDFDocObject: true,

Allowing the support of multiple languages and currencies for your invoice as outlined in jsPDF documentation:

Use of Unicode Characters / UTF-8: The 14 standard fonts in PDF are limited to the ASCII-codepage. If you want to use UTF-8 you have to integrate a custom font, which provides the needed glyphs.

Example Usage:

jsPDFInvoiceTemplate({
  //https://github.com/edisonneza/jspdf-invoice-template/issues/20#issuecomment-1859975854
  onJsPDFDocCreation: (doc: jsPDF) => {
      //var font = "...";
      doc.addFileToVFS('LiberationSans-Regular-normal.ttf', font);
      doc.addFont('LiberationSans-Regular-normal.ttf', 'LiberationSans-Regular', 'normal');
      doc.setFont('LiberationSans-Regular');
      
  },
});

• Added Support for modifying fonts by adding direct access to the jsPDF Document Object, this allows the support for additional fonts as well as changing the font for additional languages.
  • In the event additional functionality is required for certain operation it can be injected as a wrapper function for the underlying jsPDF functionality without needed to modify the base source files.

• Dynamic rows at the end of the table (total, vat, subtotal etc)
• Added stamp image at the left bottom of the page (image as a qr code)

• Separated Nodejs and Web based, into two packages
• Fixed Image and Blob type (for Nodejs)

• Added compress option
• Added custom column style (width) - (FYI: Width-> portrait: 210; landscape: 297)

• Fixed package entry point

• Added feature to add or remove columns
• Dynamic height in all columns

• Added returnJsPDFDocObject prop
• Added support for returning different outputs based on output type prop
• All parameter object properties are now OPTIONAL
• Return jspdf doc object, so now can be added new content or edited the pdf file and output it in all types that jsPDF library supports.
