Store documentation

The store is responsible for the communication between the framework and the servers. You may need to use some of its functions. To use the store in your application, make sure to import it from the root of sib-core (ie: import { store } from 'https://unpkg.com/@startinblox/core';).

API Reference

getData (async)

Fetch and cache the data for a resource

parameters - id: string: uri of the resource - context: object (optional): used to expand the id and to access the resource predicates from a compact form

returns - resource: Proxy

get

Synchronously returns a resource from the cache.

parameters - id: string: uri of the resource

returns - resource: Proxy: or null if the resource is not in cache

post (async)

Send a POST request to create a resource in a container. When the request succeed, the resource is cleared from the cache, and the components showing it are notified.

parameters - resource: object: values of the resource to create - id: string: uri of the container

returns - resourceId: string: id of the created resource

put (async)

Send a PUT request to edit a resource. When the request succeed, the resource is cleared from the cache, and the components showing it are notified.

parameters - resource: object: new values of the resource to edit - id: string: uri of the resource

returns - resourceId: string: id of the edited resource

patch (async)

Send a PATCH request to edit a resource. When the request succeed, the resource is cleared from the cache, and the components showing it are notified.

parameters - resource: object: new values of the resource to edit - id: string: uri of the resource

returns - resourceId: string: id of the edited resource

delete (async)

Send a DELETE request to delete a resource. When the request succeed, the resource is cleared from the cache, and the components showing it are notified.

parameters - id: string: uri of the resource to delete - context: object (optional): used to expand the id if needed

returns - resourceId: string: id of the deleted resource

subscribeTo

Make a resource listen another one. When a change is detected on a resource, all the resources which are listening are removed from the cache, and the component showing them are notified to re-render their content.

parameters - resourceToUpdate: resource which needs to be updated when another one change - resourceToListen: resource on which listen for changes

clearCache

Manually remove a resource from the cache

parameters - id: uri of the resource to remove from the cache

Store reactivity

The store is reactive. It means that any change you make on a resource in your app will be reflected in the interface automatically. However, there are some limitations: - If you make some changes on a resource which is in a virtual container, other virtual containers including this resource may not be updated. (ie: POST on circles/1/members does not update users/admin/circles/) - If a resource a multi nested field is displayed in a component, it may not be updated. (ie: in a sib-display, I display nestedResource.user.name from resource, changing user will not update the display)
