In-depth Guide - setting application route and env

DoneJS
1

Hi everybody,
I would like to start a new project with DoneJS and I’m diving in the in-depth guide, but i’m stuck because i don’t understand how the routing works.

In the example (using done-serve) the route.register is called without setting the route.data before:

const AppViewModel = DefineMap.extend({
  page: 'string',
  slug: 'string',
  action: 'string',
  
   // env: {
   //   default: () => { return {NODE_ENV:'development'}; },
   //   serialize: false
//},

  title: {
    default: 'place-my-order',
    serialize: false
  }
});

route.register('{page}', { page: 'home' });
route.register('{page}/{slug}', { slug: null });
route.register('{page}/{slug}/{action}', { slug: null, action: null });

export default AppViewModel;

And it works well but i cannot figure out how.
But, it I don’t use the done-serve, and i set up a Express server using done-ssr-middleware I get that the prop page is not defined in the the viewModel.

In addition, I got problem with the env status added in the viewModel. When I uncomment the env definition, i get the following error:

TypeError: Cannot define property statusCode, object is not extensible

Any suggestions?

Hi @fp_dev,

route.register is called without setting the route.data before

This is done automatically by done-autorender which is why you don’t have to do it yourself.

TypeError: Cannot define property statusCode, object is not extensible

This error happens when trying to set a property on a sealed object, which can-define/map/map is by default. I think it’ll work correctly if you define statusCode on your AppViewModel.
