If I use caches in my service worker code then Google Closure Compiler (launched with the advanced optimizations mode) will tell me :
/var/www/html/perso/otraSite/web/js/sw_viaTypescript.js:79: ERROR - [JSC_UNDEFINED_VARIABLE] > variable caches is undeclared })(caches); ^^^^^^
1 error(s), 0 warning(s)
A workaround that I use until now is ... I put window.caches so Google Closure Compiler succeeds to compile but if I let that code, browsers will tell me :
sw.js:18 Uncaught ReferenceError: window is not defined
So I replace window.caches by caches in the code compiled by Google Closure Compiler afterwards but ... having to do this every single time is pretty annoying.
Is there a cleaner way to handle it?
