Part 1: Running a scalable & reliable GraphQL endpoint with Serverless
Part 2: AppSync Backend: AWS Managed GraphQL Service
Part 3: AppSync Frontend: AWS Managed GraphQL Service
This starter kit is an opinionated set of tools combined to help you get started building a Serverless application with a GraphQL endpoint and deploy them to production in minutes.
This example uses the following technologies:
-
Frontend
-
Backend
- Serverless
- AWS AppSync DynamoDB, Elasticsearch and Lambda Integrations
- AWS Lambda & AWS API Gateway
- Apollo Server Lambda 2.0
- DynamoDB
- RDS (MySQL, PostGres and Aurora)
- REST API
- Plugins
-
Other Utilities and Integrations
You need to have Node 6 or higher installed.
npm install -g serverless
npm install -g yarn
npm install -g netlify-cli
Install Dependencies.
yarn install
Please note: AWS CLI is required to be installed on your system
- Select Backend
-
AWS Appsync (Serverless Offline does not support Appsync at this point)
- AWS DynamoDB
- AWS ElasticSearch
- AWS Lambda
-
Lambda Backend (Serverless Offline Supported)
- Twitter Rest API
cd app-backend/rest-api yarn start
Generate your Consumer Key and Secret Key for a Twitter App and update config
-
DynamoDB
cd app-backend/dynamodb yarn start -
RDS
cd app-backend/rds yarn start
- Twitter Rest API
- Start FrontEnd (Apollo Client or Appsync Client)
-
For Appsync Backend please select Appsync Client Integration:
cd app-client/appsync-client/ yarn start -
For Lambda Backend please select Apollo Client Integration:
cd app-client/apollo-client/ yarn start
Also, please make sure GraphQL endpoint is configured correctly in config/security.env.local to run client on local.
- Start GraphiQL
http://localhost:4000/graphiql
- Start GraphQL Playground (GraphiQL replacement - coming soon)
http://localhost:4000/playground
rest-api and dynamodb backends route GET and POST to the same /graphql endpoint handler
http://localhost:4000/graphql
- Sample Query for GraphiQL, Playground or GraphQL
{
getUserInfo(handle: "Madalyn61") {
name
tweets {
items {
retweeted
retweet_count
favorited
tweet
}
}
topTweet {
retweeted
retweet_count
favorited
}
}
}
If you've followed me this far, DynamoDB will now be available and running on your local machine at http://localhost:8000/shell:
Configure your AWS keys. Here you can find a 2min walkthrough how to do retrieve the keys.
sls config credentials --provider aws --key <your_aws_access_key> --secret <your_aws_secret_key>
You need to make sure you have access to your deployed lambda functions.
- Select Backend
- AWS Appsync (Supported by Serverless-AppSync-Plugin)
Note Please make sure latest serverless package is installed npm install -g serverless@latest
To use aws appsync you will need to create cognito user pool to authenticate the API Reference
- AWS DynamoDB
cd app-backend/appsync/dynamodb
yarn deploy-prod
yarn deploy-appsync
- AWS ElasticSearch
cd app-backend/appsync/dynamo-elasticsearch-lambda
yarn deploy-prod
yarn deploy-appsync
- AWS Lambda
cd app-backend/appsync/lambda
yarn deploy-prod
yarn deploy-appsync
-
Lambda Backend (Serverless Offline Supported)
-
Twitter Rest API
cd app-backend/rest-api yarn deploy-prod -
DynamoDB
cd app-backend/dynamodb yarn deploy-prod -
RDS
-
Create RDS Instance. For example - PostGres Tutorial
-
Please make sure connectivity to production RDS instance works (For example: test via razersql)
-
Edit the
config/security.env.prodfile and replace theDATABASE_URLvariable with your amazon rds endpoint (eg: postgres://${username}:{password}@${endpoint):5432/${dbName}). -
Run the deployment command
cd app-backend/rds yarn deploy-prod
-
-
- Config: Get your /graphql POST endpoint as shown below and use it in config/security.env.prod NOTE Please remove all quotes and <> and place only your POST endpoint url otherwise you will get 405 method not allowed error on POST to your endpoint
- Select Frontend (apollo-client or appsync-client)
-
Note:
- For lambda please use apollo-client
- For appsync backend please use appsync-client
- Please note that backend is deployed before deploying frontend.
- You can deploy the client on AWS S3 or Netlify.
-
AWS S3
-
First you will need to choose custom s3 bucket name for client. For ex: s3-firstname-serverless-graphql. Please note that bucket name must be unique across all aws buckets.
-
Now, in
app-client/<client-name>/serverless.ymledit thecustom.client.bucketNameproperty and replace it the bucket name above. -
Now, in
app-client/<client-name>/package.jsonedit thehomepageproperty withhttps://${yourBucketName}.s3-website-us-east-1.amazonaws.com. For ex: https://s3-bucketname-serverless-graphql.s3-website-us-east-1.amazonaws.com -
Run the deployment command
cd app-client/<client-name>/ yarn deploy-s3 # Your deployment url will be printed on the console -
Your deployment url will be : https://s3.amazonaws.com/[bucket-name]/index.html
-
-
Netlify
-
First you will need to create a new account. Please see https://www.netlify.com/docs/cli/ for details.
-
Remove homepage property in
app-client/<client-name>/package.json. This property is not required while deploying to netlify but is required for aws s3 deployment. -
The first time you use the cli tool, you’ll be asked to authenticate through the browser. After you authenticate netlify will store an access token in a global ~/.netlify/config
-
Run deployment command
cd app-client/<client-name>/ yarn deploy-netlify- ? No site id specified, create a new site (Y/n) Y
- ? Path to deploy? (current dir) build
-
Your deployment url will be printed on the console
-
