**`bookmarks.getTree()`** renvoie un tableau contenant la racine de l'arborescence des signets en tant qu'objet {{WebExtAPIRef("bookmarks.BookmarkTreeNode")}}.

Vous pouvez accéder à l'intégralité de l'arborescence de manière récursive en utilisant sa propriété `children` et la propriété `children` de ses descendants, s'ils sont eux-mêmes des dossiers.

C'est une fonction asynchrone qui renvoie une [`Promise`](/fr/docs/Web/JavaScript/Reference/Objets_globaux/Promise).

## Syntaxe

```js
var gettingTree = browser.bookmarks.getTree()
```

### Paramètres

None.

### Valeur retournée

Une [`Promise`](/fr/docs/Web/JavaScript/Reference/Objets_globaux/Promise) qui sera remplie avec un tableau contenant un objet, un objet  [`bookmarks.BookmarkTreeNode`](/fr/Add-ons/WebExtensions/API/bookmarks/BookmarkTreeNode) le noeud racine.

## Exemples

Cet exemple imprime l'intégralité de l'arborescence des signets :

```js
function makeIndent(indentLength) {
  return ".".repeat(indentLength);
}

function logItems(bookmarkItem, indent) {
  if (bookmarkItem.url) {
    console.log(makeIndent(indent) + bookmarkItem.url);
  } else {
    console.log(makeIndent(indent) + "Folder");
    indent++;
  }
  if (bookmarkItem.children) {
    for (child of bookmarkItem.children) {
      logItems(child, indent);
    }
  }
  indent--;
}

function logTree(bookmarkItems) {
  logItems(bookmarkItems[0], 0);
}

function onRejected(error) {
  console.log(`An error: ${error}`);
}

var gettingTree = browser.bookmarks.getTree();
gettingTree.then(logTree, onRejected);
```
