pdf-generator-lambda

This minimalistic service renders an HTML template with Mustache and returns a PDF in DIN-A4 format.

Usage

Do a POST request to your /renderPdf endpoint with the following body:

{
    "template":"Invoice {{invoiceNumber}} goes to {{billTo.name}}, {{billTo.street}} {{billTo.zip}} {{billTo.city}}",
    "data":{
        "invoiceNumber":"666"
        "billTo": {
            "name": "John Doe",
            "street": "8213 Mainstreet",
            "zip": "90210",
            "city": "Beverly Hills, CA"
        }
    },
    "desiredFilename": "invoice.pdf"
}

This will result in the following PDF

You'll find a more sophisticated example in the examples folder.
