Have an option to use snake_case for message properties

[vgoloviznin]

protobuf.js version: 6.1.1

I'm running pbjs utility to generate JSON for my proto files, but the issue is that it generates camelCase property names (proto files have snake_case).

Is there already some configuration for this (found a broken link to wiki article) or is it possible to include one?

[dcodeIO]

Currently, v6 always converts to camel case for simplicity. Google's JS implementation also does this. pbjs's proto2/3 targets always convert back.

Do you have a specific use case where this fails or snake_case is absolutely required?

[vgoloviznin]

Can't say that I have a hard requirement for snake_case :)
We have all documentation for communication between services where all field names are in snake case, so it's just easier to blindly follow the documentation (or reading the proto file) without thinking about camel case conversion

[dcodeIO]

pbjs now supports the option --keep-case that skips the camel case conversion. I haven't tested this for edge cases in detail, yet, so let me know if there are any issues.

@dcodeIO cool! When will it get released on npm?

[dcodeIO]

Maybe tonight as 6.2.1 if there are no more pending issues.

Awesome, thanks for the quick fix!

I will check during the weekend for our definition

It's on npm now! Feel free to reopen if there are issues.

Hi!
Apologies if it's a silly question, I'm just familiarising myself with your library, but haven't found an answer to this in the docs, this issue is as close as I got.
I have the same problem as the OP, but I'm not using the CLI to generate a json file.
Is there an equivalent option that can be set in the proto file or elsewhere that will have the same effect (leave the snake case intact) in case I'd like to load the raw proto file directly with protobuf.load()?
Thanks!

[dcodeIO]

Yes: Root#load

var root = new protobuf.Root();
root.load(..., { keepCase: true }).then(...);

Great, thanks for your help!

Thank you help,

I finally found the answer

Is there a way to --keep-case for static modules. Its a big problem when using typescript.
