Serverless Graphql API

Graphql API running on AWS Lambda in a custom VPC with RDS Postgres as a data source. All infrastructure is managed by the AWS CDK.

Getting started

export AWS_PROFILE=YOUR_PROFILE
export CDK_DEFAULT_REGION=YOUR_REGION
export CDK_DEFAULT_ACCOUNT=YOUR_ACCOUNT

Note

Install npm install -g typeorm ts-node typescript aws-cdk

1. Git Fork this repo.

2. Bootstrap CDK

cdk bootstrap aws://${CDK_DEFAULT_ACCOUNT}/${CDK_DEFAULT_REGION} --cloudformation-execution-policies arn:aws:iam::aws:policy/AdministratorAccess

3. Create RDS Password secret in SecretsManager

aws secretsmanager create-secret --name rdsPassword --description "RDS Password" --secret-string YOUR_PASSWORD >> rdsPasswordARN.txt

Save ARN for secret to be used later.

4. Create Github Token and store it as a secret in SecretsManager.

Follow this doc for setting up github webhook token https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/creating-a-personal-access-token

After that save token in SecretsManger as a secure string

aws secretsmanager create-secret --name github-token --description "Secret for GitHub" --secret-string "GITHUB_PERSONAL_ACCESS_TOKEN" >> githubTokenARN.txt

5. Create a .env file cp .env.example .env and update the GITHUB_OWNER variable to fit your GitHub username.

Deploy Stack

1. Build the App to compile it from TS to JS. npm run build:app

2. Deploy all stacks cdk deploy PipelineStack The PipelineStack will deploy the other resources for you. (set --profile YOURPROFILE if you haven't ran export AWS_PROFILE=YOUR_PROFILE)

3. (optional) Deploy all stacks cdk deploy --all

Note: You can also deploy single stacks at a time with cdk deploy STACKNAME

Note

Currently there is a bug with the Service Role on CodeBuild and needs to be manually updated.

Delete the Application and all Stacks

cdk destroy --all

Useful commands

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth emits the synthesized CloudFormation template
