Current behavior

Translation programmatically is not working at all.

Expected behavior

Being able to translate somehow in the component.

Minimal reproduction of the problem with instructions

1. Inject transloco service in the component where I want to use it
2. Call translate() method with the exact string to the value to be translated like this: this.service.translate('section.subsection.value')
3. It returns nothing

No matter if I inject the service using constructor(private service: TranslocoService) {} or I directly import translate() function. Both of them do nothing.

I know the path to the value in the translation files is correct, since it works using the template approach.

By the way, I'm not providing a stackblitz demo since I've not been able even to reproduce the transloco-example in the stackblitz. Is the project and the demo still being supported?

Hi @t0nyak,

Your problem is that the translation files did not successfully load yet when you tried to use the tranlate method.

From the docs:
"Note that in order to safely use this method, you are responsible for ensuring that the translation files have been successfully loaded by the time it's called. If you aren't sure, you can use the selectTranslate() method instead"

how to load the translation files before calling any method

Note that in order to safely use this method, you are responsible for ensuring that the translation files have been successfully loaded by the time it's called.

is this possible ? If not translate method should be removed

@sysmat @gs-mhashir I recommended reading the docs.
