Make NelmioJsLoggerBundle usable without inline JavaScript

[thkoch2001]

Hi,

I just found NelmioJsLoggerBundle while fetching nelmio/security-bundle into my project. We might just include JS error logging too. But we want to get rid of inline JavaScript too!

It should be easy to also provide a JavaScript file that can be included instead of the inline JavaScript generated by the twig tags.

Would you be interested in a PR for that?

I'm all for it but it might prove a bit hard to do since you have dynamic bits in there like the reporting URL, log function name and possibly others. In any case if you figure it out and get it to work well feel free to send a PR!

An easy way to do it could be to provide a controller rendering the JS code. This way, it could handle the dynamic bits easily. However, this does not play nicely with combining assets, and requires booting the framework to render the asset.
An alternative is to provide a command dumping a static JS file with it. It would work fine as long as your router is configured properly for usage in the CLI

We have a very elegant solution how we pass data to JavaScript (german):
