Thanks for the feature request @tokarenko! That sounds like a good improvement 🔥 Are you willing to try and provide it?

How to contribute a new preset is still in progress, but you can get a preview here.

Thank you for welcoming my enhancement request and your suggestion to join efforts. I will not be able to help because I have no experience with Node.js and I am quite limited in time at the moment... You are doing a great job here and I am trying to use it to enhance my Python project with AsyncAPI descriptions and code generation.

@tokarenko do you have an example you can provide of an output you are looking for? Maybe based on some example input?

I would love to convert this into a good-first-issue to make it more likely to be picked up 🙂

Please check generator at https://app.quicktype.io/ with the following settings:
"Source type" = "JSON schema"
"Language" = "Python"

@jonaslagoni Does this issue still valid? I want to work on this issue but need some guidance.

[jonaslagoni]

It is @ankur0904, however I cant give much. If all it is is adding @dataclass in front of the class syntax then it should be straight forward, but it all depends on how much you need to change 🙂

Here is the generic approach to solving this issue:

1. Determine the proper data models that you want to generate
2. Add a new Python preset: https://github.com/asyncapi/modelina/blob/master/docs/contributing.md#adding-a-new-preset
3. Adapt the preset so it generate the right output: https://github.com/asyncapi/modelina/blob/master/docs/presets.md
4. Add an example for the new preset: https://github.com/asyncapi/modelina/blob/master/docs/contributing.md#adding-examples
5. Adapt the docs

That should be it 🙂
