This is a simple script to be included via
<script type="text/javascript" src="console-log-store.min.js"></script>
into your web site. Then log messages are captured
> Logger.list()
[]
> console.log(123)
> log0 = Logger.list()[0]
Object {level: "DEFAULT", date: Wed Aug 10 2016 18:17:38 GMT+0200 (CEST), message: "123"}
> log0.level
"DEFAULT"
> log0.date
Wed Aug 10 2016 18:17:38 GMT+0200 (CEST)
> log0.message
"123"
One unavoidable problem is that the source line in the browser log then points to the console-log-store.min.js script; In Chrome you can then blackbox the script to prevent this: Dev tools -> Settings -> Blackboxing -> Add pattern "console-log-store.min.js".
Checkout and run "npm run build"
