[J4] Services vs helpers?

[MarkRS]

What's the difference between these two?

I can see (I think) that services are used with/via/by DI and helpers aren't, is there anything else?

Hello again Mark,

I my mind services are methods that help the component interact with the Joomla 4 services.

I use the helpers to interact with things that aren't directly part of Joomla, preparing information for controllers and models.

Examples are:

• Getting information from external databases
• Getting information from files.

I also use them for preparing information that is used in common with other controllers and models.

I also use them to support plugins when the are using similar information to the component.

I hope that helps.

Regards,

Peter.
