Conditionally change angular location strategy

Question

I’m trying to replace the location strategy by condition prod/dev

console.log(IonicENV.mode) <= this loges true

Then

 { provide: LocationStrategy, useClass: (IonicENV.mode == "prod") ? PathLocationStrateg HashLocationStrategy }

Although IonicEnv.mode returns prod, so the condition is true. but it always goes into using HashlocationStrategy. There is no logical explanation at all…

if I do

{ provide: LocationStrategy, useClass: (console.log(IonicENV.mode == "prod")) ? PathLocationStrategy : HashLocationStrategy }

Then everything works correctly on the server. it meets the true condition and goes into using pathLocationStrategy… Any explanations…anyone??

Answer 1

console.log() always return undefined and !!undefined is false. So

(console.log(IonicENV.mode == "prod")) ? PathLocationStrategy : HashLocationStratege

is the same as

(false) ? PathLocationStrategy : HashLocationStratege // because of braces

and is the same as HashLocationStratege
