@aws-sdk/client-appsync

What is @aws-sdk/client-appsync?

@aws-sdk/client-appsync is a part of the AWS SDK for JavaScript, which allows developers to interact with AWS AppSync, a managed service that uses GraphQL to make it easy for applications to get exactly the data they need. This package provides methods to create, update, delete, and query AppSync resources such as GraphQL APIs, data sources, and resolvers.

What are @aws-sdk/client-appsync's main functionalities?

Create GraphQL API

This code sample demonstrates how to create a new GraphQL API using the @aws-sdk/client-appsync package. It initializes the AppSync client, sets the parameters for the new API, and sends a request to create the API.

const { AppSyncClient, CreateGraphqlApiCommand } = require('@aws-sdk/client-appsync');

const client = new AppSyncClient({ region: 'us-west-2' });

const params = {
  name: 'MyGraphQLAPI',
  authenticationType: 'API_KEY',
};

const run = async () => {
  try {
    const data = await client.send(new CreateGraphqlApiCommand(params));
    console.log(data);
  } catch (err) {
    console.error(err);
  }
};

run();

Update GraphQL API

This code sample shows how to update an existing GraphQL API. It uses the UpdateGraphqlApiCommand to change the name of the API.

const { AppSyncClient, UpdateGraphqlApiCommand } = require('@aws-sdk/client-appsync');

const client = new AppSyncClient({ region: 'us-west-2' });

const params = {
  apiId: 'your-api-id',
  name: 'UpdatedGraphQLAPI',
};

const run = async () => {
  try {
    const data = await client.send(new UpdateGraphqlApiCommand(params));
    console.log(data);
  } catch (err) {
    console.error(err);
  }
};

run();

Delete GraphQL API

This code sample demonstrates how to delete a GraphQL API using the DeleteGraphqlApiCommand. It requires the API ID of the API to be deleted.

const { AppSyncClient, DeleteGraphqlApiCommand } = require('@aws-sdk/client-appsync');

const client = new AppSyncClient({ region: 'us-west-2' });

const params = {
  apiId: 'your-api-id',
};

const run = async () => {
  try {
    const data = await client.send(new DeleteGraphqlApiCommand(params));
    console.log(data);
  } catch (err) {
    console.error(err);
  }
};

run();

List GraphQL APIs

This code sample shows how to list all GraphQL APIs in your account using the ListGraphqlApisCommand.

const { AppSyncClient, ListGraphqlApisCommand } = require('@aws-sdk/client-appsync');

const client = new AppSyncClient({ region: 'us-west-2' });

const run = async () => {
  try {
    const data = await client.send(new ListGraphqlApisCommand({}));
    console.log(data);
  } catch (err) {
    console.error(err);
  }
};

run();

Other packages similar to @aws-sdk/client-appsync

apollo-server

Apollo Server is a community-driven, open-source GraphQL server that works with any GraphQL schema. It provides a robust set of features for building a GraphQL API, including schema stitching, subscriptions, and more. Unlike @aws-sdk/client-appsync, which is specific to AWS AppSync, Apollo Server can be used with any backend and is highly customizable.

graphql-yoga

GraphQL Yoga is a fully-featured GraphQL server with a focus on simplicity and ease of use. It is built on top of Express and Apollo Server, providing a simple setup and a powerful set of features. While @aws-sdk/client-appsync is tailored for AWS AppSync, GraphQL Yoga is more general-purpose and can be used with various backends.

prisma

Prisma is an open-source database toolkit that makes it easy to work with databases in a type-safe way. It provides a powerful ORM for GraphQL APIs, allowing developers to define their data models and generate a GraphQL API automatically. Prisma focuses on database interactions, whereas @aws-sdk/client-appsync is more about managing GraphQL APIs on AWS.
