Amplify Graphql API Construct
This package vends an L3 CDK Construct wrapping the behavior of the Amplify GraphQL Transformer. This enables quick development and interation of AppSync APIs which support the Amplify GraphQL Directives. For more information on schema modeling in GraphQL, please refer to the amplify developer docs.
The primary way to use this construct is to invoke it with a provided schema (either as an inline graphql string, or as one or more appsync.SchemaFile
) objects, and with authorization config provided. There are 5 supported methods for authorization of an AppSync API, all of which are supported by this construct. For more information on authorization rule definitions in Amplify, refer to the authorization docs. Note: currently at least one authorization rule is required, and if multiple are specified, a defaultAuthorizationMode
must be specified on the api as well. Specified authorization modes must be a superset of those configured in the graphql schema.
Note: only a single instance of the AmplifyGraphqlApi
construct can be invoked within a CDK synthesis at this point in time.
Examples
Simple Todo List With Cognito Userpool-based Owner Authorization
In this example, we create a single model, which will use user pool
auth in order to allow logged in users to create and manage their own todos
privately.
We create a cdk App and Stack, though you may be deploying this to a custom stack, this is purely illustrative for a concise demo.
We then wire this through to import a user pool which was already deployed (creating and deploying is out of scope for this example).
import { App, Stack } from 'aws-cdk-lib';
import { UserPool } from 'aws-cdk-lib/aws-cognito';
import { AmplifyGraphqlApi, AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct';
const app = new App();
const stack = new Stack(app, 'TodoStack');
new AmplifyGraphqlApi(stack, 'TodoApp', {
definition: AmplifyGraphqlDefinition.fromString( `
type Todo @model @auth(rules: [{ allow: owner }]) {
description: String!
completed: Boolean
}
`),
authorizationModes: {
userPoolConfig: {
userPool: UserPool.fromUserPoolId(stack, 'ImportedUserPool', '<YOUR_USER_POOL_ID>'),
},
},
});
Multiple related models, with public read access, and admin read/write access
In this example, we create a two related models, which will use which logged in users in the 'Author' and 'Admin' user groups will have
full access to, and customers requesting with api key will only have read permissions on.
import { App, Stack } from 'aws-cdk-lib';
import { UserPool } from 'aws-cdk-lib/aws-cognito';
import { AmplifyGraphqlApi, AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct';
const app = new App();
const stack = new Stack(app, 'BlogStack');
new AmplifyGraphqlApi(stack, 'BlogApp', {
definition: AmplifyGraphqlDefinition.fromString( `
type Blog @model @auth(rules: [{ allow: public, operations: [read] }, { allow: groups, groups: ["Author", "Admin"] }]) {
title: String!
description: String
posts: [Post] @hasMany
}
type Post @model @auth(rules: [{ allow: public, operations: [read] }, { allow: groups, groups: ["Author", "Admin"] }]) {
title: String!
content: [String]
blog: Blog @belongsTo
}
`),
authorizationModes: {
defaultAuthorizationMode: 'API_KEY',
apiKeyConfig: {
description: 'Api Key for public access',
expires: cdk.Duration.days(7),
},
userPoolConfig: {
userPool: UserPool.fromUserPoolId(stack, 'ImportedUserPool', '<YOUR_USER_POOL_ID>'),
},
},
});
Import GraphQL Schema from files, instead of inline
In this example, we import the schema definition itself from one or more local files, rather than an inline graphql string.
type Todo @model @auth(rules: [{ allow: owner }]) {
content: String!
done: Boolean
}
type Blog @model @auth(rules: [{ allow: owner }, { allow: public, operations: [read] }]) {
title: String!
description: String
posts: [Post] @hasMany
}
type Post @model @auth(rules: [{ allow: owner }, { allow: public, operations: [read] }]) {
title: String!
content: [String]
blog: Blog @belongsTo
}
import { App, Stack } from 'aws-cdk-lib';
import { UserPool } from 'aws-cdk-lib/aws-cognito';
import { AmplifyGraphqlApi, AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct';
const app = new App();
const stack = new Stack(app, 'MultiFileStack');
new AmplifyGraphqlApi(stack, 'MultiFileDefinition', {
definition: AmplifyGraphqlDefinition.fromFiles(path.join(__dirname, 'todo.graphql'), path.join(__dirname, 'blog.graphql')),
authorizationModes: {
defaultAuthorizationMode: 'API_KEY',
apiKeyConfig: {
description: 'Api Key for public access',
expires: cdk.Duration.days(7),
},
userPoolConfig: {
userPool: UserPool.fromUserPoolId(stack, 'ImportedUserPool', '<YOUR_USER_POOL_ID>'),
},
},
});
NOTE The 'dataSourceStrategies' configuration option is in preview and is not recommended to use with production systems.
API Reference
Constructs
AmplifyGraphqlApi
L3 Construct which invokes the Amplify Transformer Pattern over an input Graphql Schema.
This can be used to quickly define appsync apis which support full CRUD+List and Subscriptions, relationships,
auth, search over data, the ability to inject custom business logic and query/mutation operations, and connect to ML services.
For more information, refer to the docs links below:
Data Modeling - https://docs.amplify.aws/cli/graphql/data-modeling/
Authorization - https://docs.amplify.aws/cli/graphql/authorization-rules/
Custom Business Logic - https://docs.amplify.aws/cli/graphql/custom-business-logic/
Search - https://docs.amplify.aws/cli/graphql/search-and-result-aggregations/
ML Services - https://docs.amplify.aws/cli/graphql/connect-to-machine-learning-services/
For a full reference of the supported custom graphql directives - https://docs.amplify.aws/cli/graphql/directives-reference/
The output of this construct is a mapping of L2 or L1 resources generated by the transformer, which generally follow the access pattern
const api = new AmplifyGraphQlApi(this, 'api', { <params> });
api.resources.tables["Todo"].tableArn;
api.resources.cfnResources.cfnGraphqlApi.xrayEnabled = true;
Object.values(api.resources.cfnResources.cfnTables).forEach(table => {
table.pointInTimeRecoverySpecification = { pointInTimeRecoveryEnabled: false };
});
resources.<ResourceType>.<ResourceName>
- you can then perform any CDK action on these resulting resoureces.

combine
import { AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct'
AmplifyGraphqlDefinition.combine(definitions: IAmplifyGraphqlDefinition[])
Combines multiple IAmplifyGraphqlDefinitions into a single definition.
NOTE This API is in preview and is not recommended to use with production systems.
definitions
Required
the definitions to combine.
fromFiles
import { AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct'
AmplifyGraphqlDefinition.fromFiles(filePaths: string)
Convert one or more appsync SchemaFile objects into an Amplify Graphql Schema, binding them to a DynamoDB data source.
filePaths
Required
one or more paths to the graphql files to process.
fromFilesAndStrategy
import { AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct'
AmplifyGraphqlDefinition.fromFilesAndStrategy(filePaths: string | string[], dataSourceStrategy?: DefaultDynamoDbModelDataSourceStrategy | AmplifyDynamoDbModelDataSourceStrategy | SQLLambdaModelDataSourceStrategy)
Convert one or more appsync SchemaFile objects into an Amplify Graphql Schema.
NOTE This API is in preview and is not recommended to use with production systems.
filePaths
Required
one or more paths to the graphql files to process.
dataSourceStrategy
Optional
the provisioning definition for datasources that resolve @model
s in this schema.
The DynamoDB from
CloudFormation will be used by default.
fromString
import { AmplifyGraphqlDefinition } from '@aws-amplify/graphql-api-construct'
AmplifyGraphqlDefinition.fromString(schema: string, dataSourceStrategy?: DefaultDynamoDbModelDataSourceStrategy | AmplifyDynamoDbModelDataSourceStrategy | SQLLambdaModelDataSourceStrategy)
Produce a schema definition from a string input.
NOTE The 'dataSourceStrategy' configuration option is in preview and is not recommended to use with production systems.
schema
Required
the graphql input as a string.
dataSourceStrategy
Optional
the provisioning definition for datasources that resolve @model
s in this schema.
The DynamoDB from
CloudFormation will be used by default.
Protocols
IAmplifyGraphqlDefinition
Graphql Api definition, which can be implemented in multiple ways.
Properties
dataSourceStrategies
Required
public readonly dataSourceStrategies: {[ key: string ]: DefaultDynamoDbModelDataSourceStrategy | AmplifyDynamoDbModelDataSourceStrategy | SQLLambdaModelDataSourceStrategy};
Retrieve the datasource strategy mapping. The default strategy is to use DynamoDB from CloudFormation.
NOTE Explicitly specifying the 'dataSourceStrategies' configuration option is in preview and is not recommended to use with
production systems. For production, use the static factory methods fromString
or fromFiles
.
functionSlots
Required
public readonly functionSlots: MutationFunctionSlot | QueryFunctionSlot | SubscriptionFunctionSlot[];
Retrieve any function slots defined explicitly in the Api definition.
schema
Required
public readonly schema: string;
Return the schema definition as a graphql string, with amplify directives allowed.
referencedLambdaFunctions
Optional
public readonly referencedLambdaFunctions: {[ key: string ]: IFunction};
- Type: {[ key: string ]: aws-cdk-lib.aws_lambda.IFunction}
Retrieve the references to any lambda functions used in the definition.
Useful for wiring through aws_lambda.Function constructs into the definition directly,
and generated references to invoke them.
