/**
|
||||
* AXE test 1
|
||||
* What we want here: (1) Superpeer and (n) peers
|
||||
* - The peers receives only the requested data.
|
||||
* - If the Superpeer crash, must recreate all subscriptions and update the peers.
|
||||
* - If some peer crash or go offline, when connected again must receive the changes made by others while out.
|
||||
*
|
||||
* Tip: to run this `npm run testaxe`
|
||||
* Tip 2: if you clone the gun repo, you need to create a link do gun package. Do `npm install && cd node_modules && ln -s ../ gun`
|
||||
* Tip 3: If you not in localhost, run the browsers in anonymous mode because of domain security policies. https://superuser.com/questions/565409/how-to-stop-an-automatic-redirect-from-http-to-https-in-chrome
