GraphQL playground
While creating or editing a GraphQL API, all the changes made, can be tested using the the GraphiQL playground which sits under the Playground tab in API Designer.
The GraphiQL try-out playground comes with a series of features by default, which can be very useful while configuring the API:
- Syntax highlighting.
- Intelligent type ahead of fields, arguments, types, and more.
- Real-time error highlighting and reporting for queries and variables.
- Automatic query and variables completion.
- Automatically adds required fields to queries.
- Documentation explorer, search, with markdown support.
- Query History using local storage
- Run and inspect query results using any promise that resolves JSON results. 9. HTTPS or WSS not required.
- Supports full GraphQL Language Specification:
- Queries, Mutations, Subscriptions, Fragments, Unions, directives, multiple operations per query, etc
Headers
Debugging a GraphQL API might require additional headers to be passed to the requests while playing with the GraphiQL interface. (i.e. Authorization header in case of Authentication Token protection over the API);
Logs
Beside the results displayed in the GraphiQL playground, we are displaying as well a full list of logs of the triggered request, which helps a lot when debugging the API functionality.
