This library helps to keep collection data, update collection.

Each call is immutable and returns a new collection.

const items = [
    { id: 1, name: 'test1' },
    { id: 2, name: 'test2' }
]

let collection = Collection.toData(items);


collection = collection.updateOne({id: 2, name: 'Updated name'});
collection = collection.removeOne(2);
collection = collection.append({id: 3, name: 'test3'});

const list = collection.toList();

Use uniq key

When you're creating a new collection you should define the uniq key, which will be used for identification to merge, update, remove and get.

It will be automatically using for append and item and throw error if there are different collection's uniq key.

By default, it uses 'id' name for uniq key.

const items = [
    { uniqKey: 1, name: 'test1' },
    { uniqKey: 2, name: 'test2' }
]

let collection = Collection.toData(items, 'uniqKey');
collection.getOne(2) //{ uniqKey: 2, name: 'test2' }
