@unblocks/registry

All-purpose map data structure on steroids.

• Can be used to store state as global, making a true singleton that can be used across packages.
• Can be used locally as well.
• Support asynchronous values.

Install

npm install @encodable/registry global-box

Example usage

Create registries

import { Registry, SyncRegistry, makeSingleton } from '@encodable/registry';

// local registry (when globalId is not defined)
const registry = new Registry<string>();

// global registry
const globalRegistry = new Registry({ globalId: 'my-global-key' });

// create a singleton factory function
const getSingleton = makeSingleton(() => new Registry({ globalId: 'my-global-key' }));

Registering

// constant value
registry.registerValue('key', 1);
// sync loader
registry.registerLoader('key', () => 1);
// async loader
registry.registerLoader('key', () => Promise.resolve(1));

• Registry can support both constant values and sync/async loaders.
• SyncRegistry only support constant values and sync loaders.
