i want to use this library and create diagram and save in database
please help for this thank you
I recommend that you read Get Started with GoJS and then all of the pages of the Introduction that apply to the kind of app that you want to build, starting at GoJS Introduction -- Northwoods Software.
GoJS has no required components that run on the server, so you will be responsible for doing your own database programming and communications with the browser.
i need too add picture and link to per node and save this in database
can i do it for this library?
I’m not sure exactly what you want in the diagram, but you can customize the templates to include pictures. Get Started with GoJS.
For saving to database, it depends a lot on the database, platform, and communications protocols that you want your web app to use. GoJS is neutral about those choices, other than making it easy to write and read models in JSON formatted text. GoJS Using Models -- Northwoods Software
