How to get a variable from a service in a component?

Question

JavaScript

Good day!
Tell me how to get a variable from a service in a component?
There is a service where the variable is hardcoded:
public getCurrentRealm(metaEntityConfigtime: MetaEntityConfigtime){
const _realmUuid = '578ba27c-21f1-4d38-b686-397d1b1b4ef5';
metaEntityConfigtime.realmUuid = _realmUuid;
};
How to reflect this _realmUuid variable in the component?
Import of service in a component has made.

Answer 1

If I understand you correctly, then the best option is to do so.
Code in service class:

private _realmUuid = '578ba27c-21f1-4d38-b686-397d1b1b4ef5';

public getCurrentRealm(metaEntityConfigtime: MetaEntityConfigtime){
    metaEntityConfigtime.realmUuid = this._realmUuid;
};

//для внешнего использования (в компоненте)
get realmUuid(){
    return this._realmUuid;
}

Then in the component class:

...
constructor(private service: YourService){
    console.log(this.service.realmUuid);
}
...

Answer 2

Write a getter similar to the one you provided for it in the service

getRealmUuid() {
    return '578ba27c-21f1-4d38-b686-397d1b1b4ef5';
}
