Would be awesome to be able to push a set of helpers to the @preload about react-pages

Implemented in 5.0.0.

{
  preload:
  {
    helpers:
    {
      logger: ...
    }
  }
}

I don't get what you mean

Redux connect is just like your preload annotation, it allows to prefetch data before entering a route.
By default, the preload callback has this signature:

@preload(function(dispatch, getState, location, params) { return Promise })

I suggest to add a configurable helpers argument. The signature would be:

@preload(function(dispatch, getState, location, params, helpers) { return Promise })

And in the configuration we could add an option like that to configure the helpers:

preload: {
    helpers: {
            logger: (msg) => console.log("I prefetched :"+msg)
    }
}

So in my preload method, i could do something like:

@preload((dispatch, helpers) => {
    dispatch(...some_action...);
    helpers.logger("A little log");
})

Ok, and what is params in redux-connect?

  promise: ({ params, helpers }) => Promise.resolve({ id: 1, name: 'Borsch' })

It is the route params.
If my route is defined with something like that

<Route path="/page/:slug">

I would get the slug in params
