**`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);
```
