[aws-appsync] code-first implementation of mutation definition #9310
Description
Allow mutation definition for schema.
Use Case
Would allow for definition of mutation type fields alongside resolvers for a code-first approach.
Proposed Solution
const api = new GraphQLApi(stack, 'ExampleApi', {
name: 'example',
schemaDefinition: SCHEMA.CODE,
...
}
const example = api.addType('Example', {
definition: {
ScalarType.int('id').required(),
ScalarType.string('content').required(),
},
authorization: AUTH.AWS_IAM,
});
api.addMutation( 'addExample', {
type: ObjectType.custom(example),
args: {
version: {
type: type.string(),
required: true,
},
},
resolve: [{
dataSource: exampleDS,
request: MappingTemplate.dynamoDbPutItem(PrimaryKey.partition('id').auto(), Values.projecting('example')),
response: MappingTemplate.dynamoDbResultItem(),
}],
authorization: AUTH.AWS_IAM,
});Mutation is defined through a code-first approach and resolvers are mapped inline.
