¶ GraphQL Playground
¶ Starting with GraphQL
What is the better way to learn how GraphQL works with Salesforce than to try it yourself?
GraphQL Playground can be opened in a couple of seconds by going into:
App Launcher > Maven Integration Platform > GraphQLPlayground
After clicking on it and selecting the GraphQL Playground tab, a Visualforce page similar to this should open:
It contains the following areas:
- Query- Area for writing the query. We can also refer to this as a request or document
- Variables - JSON formatted variables which are referenced in the query itself
- Result - Returned values formatted as JSON
By clicking the Run query, the query is executed. The amount of time it takes for the results to be shown mainly depends on the volume and complexity of data that MIP must return and the complexity of the Object model on the Org that it is running on.
GraphQL Playground is quite helpful in grasping the GraphQL concepts, it helps to validate the queries and allows us to see what they return. It can also help to deal with errors on the fly so they can quickly be identified and corrected.
