Real-time Updates With Mercure
API Platform Admin support real-time updates by using the Mercure protocol.
Updates are received by using the useMercureSubscription
hook in the ListGuesser
, ShowGuesser
and EditGuesser
components.
To enable Mercure server-side, see the related documentation.
Once enabled, API Platform Admin for Hydra will automatically detect that Mercure is enabled and will discover the Mercure hub URL by itself.
Advanced Configuration
If you want to customize the default Mercure configuration, you can either do it with a prop in the <HydraAdmin>
or <OpenApiAdmin>
component:
import { OpenApiAdmin } from "@api-platform/admin";
export default () => (
<OpenApiAdmin
entrypoint="https://demo.api-platform.com"
docEntrypoint="https://demo.api-platform.com/docs.json"
mercure={{ hub: "https://mercure.rocks/hub" }}
/>
);
Or in the data provider factory:
import { hydraDataProvider, fetchHydra } from "@api-platform/admin";
import { parseHydraDocumentation } from "@api-platform/api-doc-parser";
const dataProvider = baseHydraDataProvider({
entrypoint,
httpClient: fetchHydra,
apiDocumentationParser: parseHydraDocumentation,
mercure: { hub: "https://mercure.rocks/hub" },
});
The mercure
object can take the following properties:
hub
: the URL to your Mercure hub (default value: null ; when null it will be discovered by using API responses)jwt
: a subscriber JWT to access your Mercure hub (default value: null)topicUrl
: the topic URL of your resources (default value: entrypoint)
