css - Angular styles HMR with isolation (webpack hmr) -

-



i have setup angular 4, webpack & hmr.

the part care style substitution. did homework , not able find working solution far.

just check: have out-of-the-box solution this?

if not guess need understand topic more:

1) algorithm angular using assigning component specific attributes css?

2) there api in angular (it's javascript, don't mind if it's public or implementation detail/"hidden") allow me reload/substitute styles given component? did research on hmr , if such api exists or it's doable love try & use it.

3) please verify if assumptions true: technical perspective shouldn't difficult - angular (at least in setup) loads styles <style> tags - if i'm not mistaken 1 per component type.

if true shouldn't big of deal find correct <style> tag & replace it's content i'm getting webpack hmr.

the problem apply isolation - compile css & apply [__ngsomething] attributes in there.
