# Page
A page is a basic container that fills up the `main` area of the Frappe.js SPA.
### Example
```js
const Page = require('frappe-core/frappe/client/view/page').Page;
let todo_list = new Page('ToDo List');
// make the current page active
todo_list.show();
```
## Structure
The page has the following elements
1. Body
## Events
You can `show` a page or `hide` a page.
## Bind Events
- `show` when a page is shown
- `hide` when a page is hidden
```js
let todo_list = new Page('ToDo List');
// run the refresh when it is shown
todo_list.on('show', () => todo_list.list.run());
```
## Current Page
The current page is maintained in `frappe.router.current_page` and is set the the lastest shown page.
