Share Data Between Containers

In this section, you will learn how to share data between containers in app-compose.

Both enable and start can receive data from other containers. This is useful when one container depends on information from another.

Example

const ingredients = createContainer({
  id: 'pizza-base',
  domain: 'kitchen',
  start: () => ({ api: { available: ['dough', 'sauce', 'cheese'] } }),
});

const chef = createContainer({
  id: 'John Doe',
  domain: 'italian-chef',
  dependencies: [ingredients],
  enable: (api) => api.ingredients.available.includes('cheese'),
  start: (api) => {
    console.log(`Making pizza with: ${api.ingredients.available.join(', ')}`);

    return { api: { dish: 'pizza' } };
  },
});
