Hi all,
I have a question regarding Hono Client dependencies.
As far as I understand, the Hono Client consists of two jars - hono-core and hono-client. These are needed in order a Hono Adapter or backend app to communicate with Hono. However, these jars bring a dependency on jjwt, which is probably reasonable. But
they also bring dependencies on the springframework core and cache, which I don't think is reasonable if you try to minimize dependencies. I mean springframework use is sporadic and could be easily avoided.
So my question is - do you try to minimize dependencies for the Hono Client. I mean when a client try to integrate Hono Client in its solution any additional dependency could be a problem (overhead, compatibility issues ...). If you target dependencies minimization
- have you decided what dependency set to stick to?
No, we haven't put much effort in minimizing the dependencies so far. But you are raising a good point. We could try to make some of the dependencies optional and try to detect during runtime, if they are available or not and use them accordingly (or not).
You are very welcome to raise a corresponding issue and (ideally) provide a PR for improving it.
PS: regarding usability - it could be good idea to make hono-core and hono-client OSGi compatible (e.g. to add OSGi import/export) in order to be easily deployed on OSGi frameworks. For instance vertx -core that you use under the hood is build like that.
We also haven't considered creating OSGi compliant manifest files yet. Again, we would be very open to a PR adding support for OSGi.
