Invoice With Auto Calculations and QR Code - TEMPLATES-SAMPLES
PDF from HTML Template sample in TEMPLATES-SAMPLES demonstrating ‘Invoice With Auto Calculations and QR Code’
template.html
<!-- this sample shows how to use {{macro}} styles variables but also how to define simple functions and conditional logic -->
<!-- Handlebars it the powerful template language based on {{Mustache}} but with conditions, js functions and much more. See https://handlebarsjs.com/ for information and samples -->

// you can use Handlebars helpers like #if, #unless, #each (see https://handlebarsjs.com/guide/builtin-helpers.html)
// but you can also define your own helper functions like the one below which takes all items and calculates total price
// see Handlebars custom helpers section: https://handlebarsjs.com/guide/#custom-helpers
// also see Handlebars playground online: https://handlebarsjs.com/examples/helper-safestring.html
