await/async how to handle unresolved promises

How do you handle promises that do not resolve? Example: class Utils { static async thisFunctionOnlyResolvesWhenPassed2AndNeverRejects(number: number) { return new Promise((resolve, reject) => { if(number === 2) { resolve(‘ok’) } }) } } console.log(await Utils.thisFunctionOnlyResolvesWhenPassed2AndNeverRejects(2)) // this will print “ok” because 2 is passed and the promise is resolved console.log(await Utils.thisFunctionOnlyResolvesWhenPassed2AndNeverRejects(5)) // this will crash…

ModuleWithProviders loaded from lazy-loaded feature module?

So I know about ModuleWithProviders and forRoot function, but idk if it’s possible to not call forRoot from App.module. Let’s take scenario: App.module |__Lazy1.module | \__Service.module |__Lazy2.module | \__Service.module \__(many more) Goal is to have Service.module provide app-wide singleton instances, but only be needed to be loaded when Lazy1/Lazy2 is fetched. With ModuleWithProviders.forRoot I’d call…
