[Question] Serverside render

[codihaus]

Hello,

I'm working on a project where I have to render the star map on the server-side, so I'm considering several options to achieve, I hope that you guys can point me out if my method is correct.

1/ Method 1: Server-side rendering

• On the frontend, after the user selects the options, we will have the global var to store the config.
• We will POST the JSON to server
• Server receive JSON and call starmap function to directly export to SVG object

So, the question for this method is: how can we get the options to store as JSON file? What is the function to render the SVG file object from JSON on the server?

2/ Method 2: Client-side rendering

• On the frontend, we will directly export current options as SVG, but not download it, we will store that object in a variable and POST the SVG as base64 to server.
• Server will add base64 image (SVG in this case) to canvas to render

So, my question is:

• How can we export the SVG without download it but storing it in a variable?

Thank you very much for this awesome lib!

Hi, you can easy get the SVG on client side using 'exportSVG' function. Here is an example: Celestial.exportSVG( function(data) { //the 'data' object is actually an SVG })
