Sometimes you need a pdf, for example for a confirmation or an invoice document, but you either don't have the possibility to install the libraries on the target system or the effort is too big.
There are a lot of great services out there, but unfortunately they didn't quite cover our use case.
That's why we created our own pdf service.
The desired page can be defined with Juno via a JSON file.
First we want to define a page:
"page-size":{
"unit":"mm",
"width":291,
"height":210
},
Next, we want the pdf to use the RobotoX character set:
"fonts":[
{
"name":"RobotoX",
"url":"https://cdn.jsdelivr.net/npm/rubik-font@0.0.3/fonts/Rubik-Light.ttf",
"kerning":true
}
],
To avoid having to redefine certain content, such as the header or the footer, you can also assign a template to the PDF.
"templates":[
{
"url":"https://cdn.alvine.io/examples/alvine-cloud-website.pdf",
"page":1,
"name":"website",
"box":"/MediaBox"
}
],
The pages key can then be used to define the corresponding contents of the page. The individual objects are defined via the type key. There are texts, text boxes, geometric objects and templates and images. The following is an example of an image.
{
"type":"image",
"url":"https://alvine.io/alvine.png",
"x":5,
"y":5,
"width":40,
"height":10
}
The JSON can then be sent to the service via the preferred way. Here we want to use curl.
curl --location --request POST 'https://juno.alvine.cloud/api/v1/create' \
--header 'Accept: application/json' \
--header 'Authorization: api-key EVALUATION' \
--header 'Content-Type: application/json' \
--data-raw '

Besides the create api there is also an api for converting web pages to PDF and converting office documents.
hope you enjoy it!
