Angular error when returning function string in service: Type '() => string' is not Assignable to type 'string'

Question

I’m having the following problem while trying to return a string of a variable of service for any other function, which is strange because all variables are strings like the return of functions.

test.service.ts

private oneString:string = "hi";

getOneString(): string {
    return this.oneString.
}    

myFunction.ts

constructor(private testeService: TesteService) { } 

private myString:string = this.service.getOneString; 

console.log(myString);

Error: Type '() => string' is not Assignable to type 'string'

Answer 1

In the builder you call your service TesteService with the following name testeService, but to call the service you put in the code this.service, that is, to work you must put this.testeService, as below

myFunction.ts

constructor(private testeService: TesteService) { } 

private myString:string = this.testeService.getOneString(); 

console.log(myString);

Answer 2

The problem was I was calling this.testeService.getOneString, and should be called was: this.testeService.getOneString() Also as commented the other problem was this.service, which should be this.testeService.

Solved !
