AppSync GraphQL Api Construct using Amplify GraphQL Transformer.
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.
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(/* GraphQL */ `
type Todo @model @auth(rules: [{ allow: owner }]) {
description: String!
completed: Boolean
}
`),
authorizationModes: {
userPoolConfig: {
userPool: UserPool.fromUserPoolId(stack, 'ImportedUserPool', '<YOUR_USER_POOL_ID>'),
},
},
});
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(/* GraphQL */ `
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>'),
},
},
});
In this example, we import the schema definition itself from one or more local files, rather than an inline graphql string.
# todo.graphql
type Todo @model @auth(rules: [{ allow: owner }]) {
content: String!
done: Boolean
}
# blog.graphql
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
}
// app.ts
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>'),
},
},
});
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> });
// Access L2 resources under `.resources`
api.resources.tables["Todo"].tableArn;
// Access L1 resources under `.resources.cfnResources`
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.

Wrapper class around Custom::AmplifyDynamoDBTable custom resource, to simplify the override experience a bit.
This is NOT a construct, just an easier way to access
the generated construct.
This is a wrapper intended to mimic the aws_cdk_lib.aws_dynamodb.Table functionality more-or-less.
Notable differences is the addition of TKTK properties, to account for the fact that they're constructor props
in the CDK construct, as well as the removal of all from*, grant*, and metric* methods implemented by Table.
