# Pages

The Pages module in GrapesJS allows you to create a project with multiple pages. By default, one page is always created under the hood, even if you don't need multi-page support. This allows keeping the API consistent and easier to extend if you need to add multiple pages later.

## Initialization

The default editor initialization doesn't require any knowledge of pages and this was mainly done to avoid introducing breaking changes when the Pages module was introduced.

This is how a typical editor initialization looks like:

```js
const editor = grapesjs.init({
  container: '#gjs',
  height: '100%',
  storageManager: false,
  // CSS or a JSON of styles
  style: '.my-el { color: red }',
  // HTML string or a JSON of components
  components: '<div class="my-el">Hello world!</div>',
  // ...other config options
});
```

What actually is happening is that this configuration is automatically migrated to the Page Manager.

```js
const editor = grapesjs.init({
  container: '#gjs',
  height: '100%',
  storageManager: false,
  pageManager: {
    pages: [
      {
        // without an explicit ID, a random one will be created
        id: 'my-first-page',
        // CSS or a JSON of styles
        styles: '.my-el { color: red }',
        // HTML string or a JSON of components
        component: '<div class="my-el">Hello world!</div>',
      },
    ],
  },
});
```

::: warning
Worth noting the previous keys are `style` and `components`, where in pages you should use `styles` and `component`.
:::

As you might guess, this is how initializing the editor with multiple pages would look like:

```js
const editor = grapesjs.init({
  // ...
  pageManager: {
    pages: [
      {
        id: 'my-first-page',
        styles: '.my-page1-el { color: red }',
        component: '<div class="my-page1-el">Page 1</div>',
      },
      {
        id: 'my-second-page',
        styles: '.my-page2-el { color: blue }',
        component: '<div class="my-page2-el">Page 2</div>',
      },
    ],
  },
});
```

GrapesJS doesn't provide any default UI for the Page Manager but you can easily built one by leveraging its [APIs][Pages API]. Check the [Customization](#customization) section for more details on how to create your own Page Manager UI.

## Programmatic usage

If you need to manage pages programmatically you can use its [APIs][Pages API].

Below are some commonly used methods:

```js
// Get the Pages module first
const pages = editor.Pages;

// Get an array of all pages
const allPages = pages.getAll();

// Get currently selected page
const selectedPage = pages.getSelected();

// Add a new Page
const newPage = pages.add({
  id: 'new-page-id',
  styles: '.my-class { color: red }',
  component: '<div class="my-class">My element</div>',
});

// Get the Page by ID
const page = pages.get('new-page-id');

// Select another page by ID
pages.select('new-page-id');
// or by passing the Page instance
pages.select(page);

// Get the HTML/CSS code from the page component
const component = page.getMainComponent();
const htmlPage = editor.getHtml({ component });
const cssPage = editor.getCss({ component });

// Remove the Page by ID (or by Page instance)
pages.remove('new-page-id');
```

## Customization

By using the [Pages API] it's easy to create your own Page Manager UI.

The simpliest way is to subscribe to the catch-all `page` event, which is triggered on any change related to the Page module (not related to page content like components or styles), and update your UI accordingly.

```js
const editor = grapesjs.init({
  // ...
});

editor.on('page', () => {
  // Update your UI
});
```

In the example below you can see an quick implementation of the Page Manager UI.
