Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Amplify Graphql API Construct

View on Construct Hub

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.

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(/* GraphQL */ `
    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(/* 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>'),
    },
  },
});

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.

# 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>'),
    },
  },
});

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> });
  // 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.
