GraphQL Store Core

@graphql-workbench/graphql-store-core provides dependency-free runtime primitives shared by the signal stores in the GraphQL components monorepo.

Install

npm install @graphql-workbench/graphql-store-core

Typed events

import { createStoreEventChannel } from '@graphql-workbench/graphql-store-core';

interface Events {
  changed: { readonly value: number };
}

const channel = createStoreEventChannel<Events>();
const unsubscribe = channel.events.subscribe('changed', ({ value }) => {
  console.log(value);
});

channel.emit('changed', { value: 1 });
unsubscribe();
channel.dispose();

Delivery is synchronous and follows subscription order. Unsubscription and disposal are idempotent. Disposed channels ignore emissions and reject new subscriptions.

Development

Run commands from the monorepo root:

npm ci
npm run check --workspace=@graphql-workbench/graphql-store-core
