Methods
static getCollectionBySlug(client, slug, params, options) → {Promise.<(Collection|null)>}
This method returns a collection, given a slug. This is typically used for home and section pages.
If the result collection contains other collections, then it will recursively fetch those collections as well, upto a maximum depth of depth.
Items that are collections will have item.story set to a story map, and items that are collections will have the fields of that collection directly set on the item.
Instead of handling all edge cases yourself, this object can be used with the Collection Component
Example
const collection = await Collection.getCollectionBySlug(client, slug, {}, {depth: 3, defaultNestedLimit: 4, nestedCollectionLimit: {ThreeColGrid: [2, 3, 4, 2, 5], FullScreenSlider: [1, 2, 3, 4, 5]}});
if(!collection) {
render404();
} else {
recursivelyDebugCollection(collection);
// <Collection ... collection={collection.asJsoo()} />
showOnTheUI(JSON.stringify(collection.asJson()))
}
function recursivelyDebugCollection(collection) {
const items = collection.items || [];
items.forEach(item => {
if(item.type === 'story') {
console.log(item.story.headline)
} else if(item.type === 'collection') {
console.log(item["associated-metadata"]["layout"]);
recursivelyDebugCollection(item);
}
})
}
