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.

Feel free for any suggestion or improvements.

Install and usage

How to install or load in my project?

This small "library" can be imported in any project via npm or in browser via CDN by using jsPDFInvoiceTemplate variable.

Get it from NPM:

``sh
npm i jspdf-invoice-template
`
Or for NodeJs:
`sh
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)
`html

How to use it?

Usage

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

`javascript
//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 );
`

What about Parameters Object?

Parameters object

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

`javascript
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,

What will be returned?

The return object depends on parameters object. See the code below:

`typescript
{
pagesNumber: number, // (always) - number of pages
jsPDFDocObject: jsPDF, // if (returnJsPDFDocObject: true) - the doc already created. You can use it to add new content, new pages.
blob: Blob, // if (outputType: 'blob') - returns the created pdf file as a Blob object. So you can upload and save it to your server. (Idea from a comment on Twitter)
dataUriString: string, // if (outputType: 'datauristring')
arrayBuffer: ArrayBuffer // if (outputType: 'arraybuffer')
}

//store it to a variable and use it wherever you want
var pdfCreated = jsPDFInvoiceTemplate.default({ ...parameters });
var blob = pdfCreated.blob;
//...
var pagesNum = pdfCreated.pagesNumber;
var pdfObject = pdfCreated.jsPDFDocObject;
`


---

How to use the returned jsPDFDocObject?

`typescript
//example: create a PDF using the template
var pdfCreated = jsPDFInvoiceTemplate.default({ ...parameters });

//add new page or new content -> see jsPDF documentation
pdfCreated.jsPDFDocObject.addPage();
pdfCreated.jsPDFDocObject.text("Test text", 10, 50);
//...

pdfCreated.jsPDFDocObject.save(); //or .output('');
`

What about fonts and special characters?

You can use the onJsPDFDocCreation property arrow function to hook into configuring the jsPDF functionality as soon as it's initialized.


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:

`typescript
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');

},
});
`


--- Changelog ---

v.1.4.4

* 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.

v.1.4.3

* 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)

v.1.4.2

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