JavaScript sucks.
No module available in WebExtension at the moment! :(
No require, no import/export.
In Worker, we have importScripts() which imports everything in this scope.
In order to use the same base of code with XUL-addon for Thunderbird and SDK-addon for Firefox,
all modules have been “objectified”. And while they are still imported via “require”
in the previous extensions, they are loaded as background scripts in WebExtension sharing
the same memory space…
When JavaScript become a modern language, “deobjectify” the modules…
ATM, import/export are not available by default:
— Chrome 60 – behind the Experimental Web Platform flag in chrome:flags.
— Firefox 54 – behind the dom.moduleScripts.enabled setting in about:config.
— Edge 15 – behind the Experimental JavaScript Features setting in about:flags.

This worker don’t work as a PromiseWorker (which returns a promise), so when we send request

That’s why the full text to analyze is send in one block, but analyse is returned paragraph
