Im putting together a javascript node package wrapper for the Warcraft Logs if anyone is about start a project and wants a wrapper to interact with the API.
https://www.npmjs.com/package/weasel.js
(the abbreviation WCL can be pronounced Weasel… I guess… thats where the module name comes from :P)
Hopefully that isn’t a real key in the docs. I use those for tracking so best not to reveal a valid one.
Not at all, as the comment suggest you have to get your own throught the account settings on WCL 
//Set the public WCL api-key that you get from https://www.warcraftlogs.com/accounts/changeuser
api.setApiKey(‘abcd123abcd123abcd123abcd123abcd123’);
Sweet. Now I can make a React frontend that isn’t laggy!
Let me know what you need and I’ll implement it.
I went ahead and pushed the project to version 1 with a slight refactor and a simple documentation with JSDoc over at https://pintapoff.github.io/weasel.js/index.html
