This is the development repository for the new StirlingPDF backend. With the power of JS, WASM & GO this will provide almost all functionality SPDF can do currently directly on the client. For automation purposes this will still provide an API to automate your workflows.

## Understanding Workflows
Workflows are the way you define what operations and their order should be applied to the PDF.
Workflows can be created via the web-ui and then exported or, if you want to brag a bit, you can create the JSON object yourself.
### Basics
To create your own, you have to understand a few key features first. You can also look at more examples our github repository.
``` json
{
"outputOptions": {
"zip": false
},
"operations": [
{
"type": "extract",
"values": {
"pagesToExtractArray": [0, 2]
},
"operations": []
}
]
}
```
The workflow above will extract the first (p\[0\]) and third (p\[2\]) page of the document.
You can also nest workflows like this:
``` json
{
"outputOptions": {
"zip": false
},
"operations": [
{
"type": "extract",
"values": {
"pagesToExtractArray": [0, 2]
},
"operations": [
{
"type": "impose",
"values": {
"nup": 2, // 2 pages of the input docuemtn will be put on one page of the output document.
"format": "A4L" // A4L -> The page size of the Ouput will be an A4 in Landscape. You can also use other paper formats and "P" for portrait output.
},
"operations": []
}
]
}
]
}
```
If you look at it closely, you will see that the extract operation has another nested operation of the type impose. This workflow will produce a PDF with the 1st and 2nd page of the input on one single page.
### Advanced
If that is not enought for you usecase, there is also the possibility to connect operations with eachother.
You can also do different operations to produce two different output PDFs from one input.
If you are interested in learning about this, take a look at the Example workflows provided in the repository, ask on the discord, or wait for me to finish this documentation.
