Examples of 68 | representing a project or community include using an official project e-mail 69 | address, posting via an official social media account, or acting as an appointed 70 | representative at an online or offline event. Representation of a project may be 71 | further defined and clarified by project maintainers. 72 | 73 | ### Enforcement 74 | 75 | Instances of abusive, harassing, or otherwise unacceptable behavior may be 76 | reported by contacting the project team at [INSERT EMAIL ADDRESS]. All 77 | complaints will be reviewed and investigated and will result in a response that 78 | is deemed necessary and appropriate to the circumstances. The project team is 79 | obligated to maintain confidentiality with regard to the reporter of an incident. 80 | Further details of specific enforcement policies may be posted separately. 81 | 82 | Project maintainers who do not follow or enforce the Code of Conduct in good 83 | faith may face temporary or permanent repercussions as determined by other 84 | members of the project's leadership. 85 | 86 | ### Attribution 87 | 88 | This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, 89 | available at [http://contributor-covenant.org/version/1/4][version] 90 | 91 | [homepage]: http://contributor-covenant.org 92 | [version]: http://contributor-covenant.org/version/1/4/ -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.

I wrote my own transformer in order to emulate AWS Amplify's method of using GraphQL directives in order to template a lot of the Schema Definition Language. 18 | 19 | This package is my attempt to convert all of that effort into a separate construct in order to clean up the process. 20 | 21 | ## How Do I Use It 22 | 23 | ### Example Usage 24 | 25 | API With Default Values 26 | ```ts 27 | import { AppSyncTransformer } from 'aws-cdk-appsync-transformer'; 28 | ... 29 | new AppSyncTransformer(this, "my-cool-api", { 30 | schemaPath: 'schema.graphql' 31 | }); 32 | ``` 33 | 34 | schema.graphql 35 | ```graphql 36 | type Customer @model 37 | @auth(rules: [ 38 | { allow: groups, groups: ["Admins"] }, 39 | { allow: private, provider: iam, operations: [read, update] } 40 | ]) { 41 | id: ID! 42 | firstName: String! 43 | lastName: String! 44 | active: Boolean! 45 | address: String! 46 | } 47 | 48 | type Product @model 49 | @auth(rules: [ 50 | { allow: groups, groups: ["Admins"] }, 51 | { allow: public, provider: iam, operations: [read] } 52 | ]) { 53 | id: ID! 54 | name: String! 55 | description: String! 56 | price: String! 57 | active: Boolean! 58 | added: AWSDateTime! 59 | orders: [Order] @connection 60 | } 61 | 62 | type Order @model 63 | @key(fields: ["id", "productID"]) { 64 | id: ID! 65 | productID: ID! 66 | total: String! 67 | ordered: AWSDateTime! 68 | } 69 | ``` 70 | 71 | ### [Supported Amplify Directives](https://docs.amplify.aws/cli/graphql-transformer/directives) 72 | 73 | Tested: 74 | * [@model](https://docs.amplify.aws/cli/graphql-transformer/directives#model) 75 | * [@auth](https://docs.amplify.aws/cli/graphql-transformer/directives#auth) 76 | * [@connection](https://docs.amplify.aws/cli/graphql-transformer/directives#connection) 77 | 78 | Experimental: 79 | * [@key](https://docs.amplify.aws/cli/graphql-transformer/directives#key) 80 | * [@versioned](https://docs.amplify.aws/cli/graphql-transformer/directives#versioned) 81 | * [@function](https://docs.amplify.aws/cli/graphql-transformer/directives#function) 82 | * These work differently here than they do in Amplify - see [Functions](#functions) below 83 | 84 | Not Yet Supported: 85 | * [@searchable](https://docs.amplify.aws/cli/graphql-transformer/directives#searchable) 86 | * [@predictions](https://docs.amplify.aws/cli/graphql-transformer/directives#predictions) 87 | * [@http](https://docs.amplify.aws/cli/graphql-transformer/directives#http) 88 | 89 | ### Authentication 90 | 91 | User Pool Authentication 92 | ```ts 93 | const userPool = new UserPool(this, 'my-cool-user-pool', { 94 | ... 95 | }) 96 | ... 97 | const userPoolClient = new UserPoolClient(this, `${id}-client`, { 98 | userPool: this.userPool, 99 | ... 100 | }) 101 | ... 102 | new AppSyncTransformer(this, "my-cool-api", { 103 | schemaPath: 'schema.graphql', 104 | authorizationConfig: { 105 | defaultAuthorization: { 106 | authorizationType: AuthorizationType.USER_POOL, 107 | userPoolConfig: { 108 | userPool: userPool, 109 | appIdClientRegex: userPoolClient.userPoolClientId, 110 | defaultAction: UserPoolDefaultAction.ALLOW 111 | } 112 | } 113 | } 114 | }); 115 | ``` 116 | 117 | #### IAM 118 | 119 | Unauth Role: TODO 120 | 121 | Auth Role: Unsupported (for now?). Authorized roles (Lambda Functions, EC2 roles, etc) are required to setup their own role permissions. 122 | 123 | ### Functions 124 | 125 | Fields with the `@function` directive will be accessible via `api.outputs.FUNCTION_RESOLVERS`. It will return an array like below.Currently these are not named and do not specify a region. There are improvements that can be made here but this simple way has worked for me so I've implemented it first. Typically I send all `@function` requests to one Lambda Function and have it route as necessary. 126 | 127 | ```js 128 | [ 129 | { typeName: 'Query', fieldName: 'listUsers' }, 130 | { typeName: 'Query', fieldName: 'getUser' }, 131 | { typeName: 'Mutation', fieldName: 'createUser' }, 132 | { typeName: 'Mutation', fieldName: 'updateUser' } 133 | ] 134 | ``` 135 | 136 | ### DataStore Support 137 | 138 | 1. Pass `syncEnabled: true` to the `AppSyncTransformerProps` 139 | 1. Generate necessary exports (see [Code Generation](#code-generation) below) 140 | 141 | ### Code Generation 142 | 143 | I've written some helpers to generate code similarly to how AWS Amplify generates statements and types. You can find the code [here](https://github.com/kcwinner/advocacy/tree/master/cdk-amplify-appsync-helpers). 144 | 145 | ## Versioning 146 | 147 | I will *attempt* to align the major and minor version of this package with [AWS CDK], but always check the release descriptions for compatibility. 148 | 149 | I currently support [![GitHub package.json dependency version (prod)](https://img.shields.io/github/package-json/dependency-version/kcwinner/aws-cdk-appsync-transformer/@aws-cdk/core)](https://github.com/aws/aws-cdk) 150 | 151 | ## Limitations 152 | 153 | * 154 | 155 | ## Contributing 156 | 157 | See [CONTRIBUTING](CONTRIBUTING.md) for details 158 | 159 | ## License 160 | 161 | Distributed under [Apache License, Version 2.0](LICENSE) 162 | 163 | [aws cdk]: https://aws.amazon.com/cdk -------------------------------------------------------------------------------- /codecov.yml: -------------------------------------------------------------------------------- 1 | coverage: 2 | precision: 2 3 | round: down 4 | range: "50...100" -------------------------------------------------------------------------------- /docs/API.md: -------------------------------------------------------------------------------- 1 | # API Reference 2 | 3 | **Classes** 4 | 5 | Name|Description 6 | ----|----------- 7 | [AppSyncTransformer](#aws-cdk-appsync-transformer-appsynctransformer)|AppSyncTransformer Construct. 8 | 9 | 10 | **Structs** 11 | 12 | Name|Description 13 | ----|----------- 14 | [AppSyncTransformerProps](#aws-cdk-appsync-transformer-appsynctransformerprops)|Properties for AppSyncTransformer Construct. 15 | 16 | 17 | 18 | ## class AppSyncTransformer 🔹 19 | 20 | AppSyncTransformer Construct. 21 | 22 | __Implements__: [IConstruct](#constructs-iconstruct), [IConstruct](#aws-cdk-core-iconstruct), [IConstruct](#constructs-iconstruct), [IDependable](#aws-cdk-core-idependable) 23 | __Extends__: [Construct](#aws-cdk-core-construct) 24 | 25 | ### Initializer 26 | 27 | 28 | 29 | 30 | ```ts 31 | new AppSyncTransformer(scope: Construct, id: string, props: AppSyncTransformerProps) 32 | ``` 33 | 34 | * **scope** ([Construct](#aws-cdk-core-construct)) *No description* 35 | * **id** (string) *No description* 36 | * **props** ([AppSyncTransformerProps](#aws-cdk-appsync-transformer-appsynctransformerprops)) *No description* 37 | * **schemaPath** (string) Required. 38 | * **apiName** (string) Optional. __*Default*__: `${id}-api` 39 | * **authorizationConfig** ([AuthorizationConfig](#aws-cdk-aws-appsync-authorizationconfig)) Optional. __*Default*__: API_KEY authorization config 40 | * **fieldLogLevel** ([FieldLogLevel](#aws-cdk-aws-appsync-fieldloglevel)) Optional. __*Default*__: FieldLogLevel.NONE 41 | * **syncEnabled** (boolean) Optional. __*Default*__: false 42 | 43 | 44 | 45 | ### Properties 46 | 47 | 48 | Name | Type | Description 49 | -----|------|------------- 50 | **appsyncAPI**🔹 | [GraphQLApi](#aws-cdk-aws-appsync-graphqlapi) | 51 | **nestedAppsyncStack**🔹 | [NestedStack](#aws-cdk-core-nestedstack) | 52 | **tableNameMap**🔹 | any | 53 | 54 | 55 | 56 | ## struct AppSyncTransformerProps 🔹 57 | 58 | 59 | Properties for AppSyncTransformer Construct. 60 | 61 | 62 | 63 | Name | Type | Description 64 | -----|------|------------- 65 | **schemaPath**🔹 | string | Required. 66 | **apiName**?🔹 | string | Optional.
