How to get the license key?

The document says “Our server will generate a GoJS license key for you”. How to get the key?By ajax?What if i use it offline? By the way,where is the love button?

Purchase a license, then get a license key.

License is written into your code. No need to download license via AJAX so you can use it offline.

Yes, the GoJS library never “phones home” – it never initiates any network traffic except for loading the images that you specify via Picture.source.
