components idea is kinda there, although I think it should end up in new packages location where I think templates should be.

so far exploring below - but need few days to finalize actually working JS websocket client

[derberg]

just pushed a very simple js websocket client implementation in a new special template structure

now I think next steps are to:

• try to do python websocket client and see if there will be a possible reusability across languages
• try to do js mqtt client and see if there will be a possible reusability across protocols

and yeah above should kinda prove that the structure and granularity that is part of it make sense

long way ahead

[derberg]

No activity in PR doesn't mean no work. I consulted with other community folks in #generator channel in Slack:

• idea of @asyncapi/generator library
• idea of structured templates in the repo, instead of app per template
• exploring what we can do to merge such PoC to master without releasing
