Create, update, and delete application data
In this guide, you will learn how to create, update, and delete your data using Amplify Libraries' GraphQL client.
Before you begin, you will need:
In GraphQL, mutations are APIs that are used to create, update, or delete data. This is different than queries, which are used to read the data but not change it. The following examples demonstrate how you can create, update, and delete items using the Amplify GraphQL client.
Now that the client is set up, you can run a GraphQL mutation with
Amplify.API.mutate to create your data.
1Todo todo = Todo.builder()2 .name("My todo")3 .build();45Amplify.API.mutate(ModelMutation.create(todo),6 response -> Log.i("MyAmplifyApp", "Todo with id: " + response.getData().getId()),7 error -> Log.e("MyAmplifyApp", "Create failed", error)8);
To update data, use
To delete data, use
Congratulations! You have finished the Create, update, and delete application data guide. In this guide, you created, updated, and deleted your app data through the GraphQL API.
Our recommended next steps include using the API to query data and subscribe to real-time events to look for mutations in your data. Some resources that will help with this work include:
