Issue Description

Trying to implement the new schema introduced by v0.10 I was stuck on error: SchemaSerializer error. See:

The thing is I was using the new schema so I started debugging.

It turns out I was missing a room decorator: @serialize(SchemaSerializer) which isn’t mentioned anywhere in docs that you have to use.

The only context this decorator is mentioned in is with fossil serializer.

@endel The changes to the config in do allow the project to be compiled, room to be created and clients to join, however, state updates are not sent to client.

When I compile the same project with tsc, the updates start working.

I’ve been playing around with this today, and I’ve managed to get rid of the SchemaSerializer error using this configuration:

The problem is deeper than it seems, though. Babel currently cannot play nicely with TypeScript’s (“legacy”) decorators, here are some relevant issues on their issue tracker:

I believe the root of this issue is because of the initializerDefineProperty_default calls generated by Babel, here:

let TestRoom_State = (_dec = Object(schema_["type"])("string"), _dec2 = Object(schema_["type"])("number"), (_class = (_temp = class State extends schema_["Schema"] {
  constructor() {

    initializerDefineProperty_default()(this, "someAtr", _descriptor, this);

Unfortunately I don’t know how high is for the Babel team to fix this.
