How to change the default behavior of the typescript generator

Hilla
1

Hello,

I try to force hilla to convert my Java long in Typescript string.

For the moment I can change how Hilla convert my long in JSON using Jackson2ObjectMapperBuilderCustomizer. If I inspect request, I can see that hilla send my long in json string but in the Corresponding Typescript file generated, it remain a “number”.

As long as I don’t manipulate these numbers, it is not a problem because at runtime, it is a JS string. But if i want do something like an addition, the Typescript compilator won’t warn me.

The conversion of Java long to Typescript number can be dangerous with large number. I prefere that the default behabior is a long to string conversion and the client will be able to choose if he want keep string or convert in number (and how he do the conversion).

In general, those transformations are handled at DTO level, although I understand that it can be cumbersome if you have many of them.

I know that it is better practice to always use specific DTO. But we already have a public API to interface our product with other softwares. It would be really tedious to create an exact copy of our existing dto by changing only long to String.

Enjoy Javascript limitations …

Generally speaking, do you know if there is a mechanism in Hilla to customize the Typescript generation ?

If not, I will resign myself to create a lot of new DTO.
