connectTag(tagName, connection)

Registers a custom element named tagName so it can make requests through connection.

Create the custom element using your connection:

import {connectTag, restModel, DefineMap, DefineList} from "can";

const Todo = DefineMap.extend({
    id: {identity: true, type: "number"},
    name: "string"
});
Todo.List = DefineList.extend({"#": Todo});

Todo.connection = restModel({
    url: "/todos/{id}",
    Map: Todo
});

connectTag("todo-model", Todo.connection);

Then, use the custom element in your can-stache views.

Use getList to retrieve a list of items. The contents of the element will be rendered with a Promise<Todo.List> as the context:

<todo-model getList="type='new'">
  <ul>
  {{#isPending}}<li>Loading</li>{{/isPending}}
  {{# if( isResolved ) }}
    {{# each(value) }}
      <li>{{name}}</li>
    {{/ each}}
  {{/ if}}
  </ul>
</order-model>

Use get to retrieve a single item by id. The contents of the element will be rendered with a Promise<Todo> as the context:

<todo-model get="id=5">
  {{#isPending}}<li>Loading</li>{{/isPending}}
  {{# if( isResolved ) }}
    <span>{{name}}</span>
  {{/ if}}
</order-model>
