You could put logic your custom base page to add a <script> tag to the head of the document that makes all the information available to javascript applications:
```
<head>
  ...
  <script>
    window.appInfo = {
      user: 'foo',
      bar: 'baz'
    };
  </script>
</head>
<body aurelia-app="main">
  ...
```
Then in your aurelia app you can access this info as needed:
```
export class App {
  constructor() {
    let info = window.appInfo;
    // do something with the app info...
  }
  ...
}
```
You could even register the object in the container, enabling you to declare it as a dependency. This will make your code more portable and testable.

In main.js: aurelia.container.registerInstance('app-info', window.appInfo);
```
@inject('app-info')
export class App {
  constructor(info) {
    // do something with the app info...         
  }
  ...
}
```
