Colyseus Schema in Cocos

[Noisycall]

Is it possible to use the generated schema from Colyseus inside cocos-creator? Installing @colyseus/schema and using the generated schemas doesn’t seem to work

Cocos package.json

Generated Schema File

Error:

It seems to be saying there is some kind of circular reference for the “type” decorator, which is preventing compilation.

Any help is appreciated!

I dont know a lot about this but I can ask engineering to have a look.

And it looks like Creator 3.3.2?

[Noisycall]

Yes, it is version 3.3.2
Thank you

It is possible to use @colyseus/schema. I have installed and working properly.

Here is my demo:
55351.zip (1.6 MB)

When I ran npm install and opened the project in cocos, it gave me the same error

If you are on Mac, could this be a Windows specific issue? Could you also specify your node version so i know its not a node version mismatch? I am using 16 LTS

Sorry, I overlooked this error, you can open project settings and set Exports Conditions to empty,and it will works.

The second way, you can use Schema like this:

in this way,you need to add “allowSyntheticDefaultImports”: true to tsconfig.json.

[Noisycall]

The second way (I think specifically the import s from @colyseus/schema) made it work, now the error is not there. The other method still seemed to have that error.
Thank you!
