Overview

The svelte-keyed package is a writable derived store for objects and arrays. It provides a solution to common limitations in working with Svelte auto-subscriptions, allowing for easier management of object store properties and the extraction of functionality into external helper functions.

Features

• Writable Derived Store: svelte-keyed provides a writable derived store for objects and arrays, allowing for easy management of store updates.
• Nullable Parents: If the parent store is nullable, the child store will also be nullable, providing flexibility in handling nullable properties.
• TypeScript Support: svelte-keyed supports TypeScript, inferring the return type of the keyed store from the keypath. It also tries to guess all possible keypaths up to a depth limit of 3.

Installation

To install svelte-keyed, you can use npm. Since Svelte automatically bundles all required dependencies, you only need to install this package as a dev dependency with the -D flag.

npm install svelte-keyed -D
