# CDK API with GraphQL and Aurora Serverless PostgreSQL
This CDK stack deploys a real-time GraphQL API built with AWS AppSync, Amazon Aurora Serverless PostgreSQL, and AWS Lambda.
## Getting started
To deploy this project, follow these steps.
1. Clone the project
```sh
git clone https://github.com/dabit3/graphql-api-cdk-serverless-postgres.git
```
2. Change into the new directory and install dependencies
```sh
cd graphql-api-cdk-serverless-postgres
npm install
```
3. Change into the __lambda-fns__ directory and install the dependencies for the Lambda function package:
```sh
cd lambda-fns
npm install
cd ..
```
4. Run the build
```sh
npm run build
```
5. Deploy the stack
```sh
cdk deploy --O cdk-exports.json
```
6. Create the posts table
Visit the [RDS dashboard](https://console.aws.amazon.com/rds/home) and click on __Query Editor__. From the dropdown menu, choose the database (it should begin with __appsynccdkrdsstack-aurorablogcluster__).
For the Database username, choose __Connect with a Secrets Manager ARN__.
To sign in, you will need the ARN from the secret that was created by CDK. To get this secret, in a new window open [AWS Secrets manager](https://console.aws.amazon.com/secretsmanager/home). Here, click on the secret that was created by CDK (it should start with __AuroraBlogClusterSecret__). Copy the Secret ARN to your clipboard and go back to the RDS Query Editor.
Next, use the __Secret ARN__ as the __Secrets Manager ARN__ and __BlogDB__ as the name of the database. Next, press enter and click on Connect to Database.
Once signed in, create the __posts__ table by executing the following query:
```sql
CREATE TABLE posts (
id text UNIQUE,
title text,
content text
);
```
7. Testing the API
Next, visit the [AppSync console](https://console.aws.amazon.com/appsync/home) and click on __cdk-blog-appsync-api__ to view the dashboard for your API.
Next click on __Queries__ in the left hand menu to view the query editor. From here, we can test out the API by running the following queries and mutations:
```graphql
mutation createPost {
createPost(post: {
id: "001"
title: "My first post!"
content: "Hello world!"
}) {
id
title
content
}
}
query listPosts {
listPosts {
id
title
content
}
}
query getPostById {
getPostById(postId: "001") {
id
title
content
}
}
mutation updatePost {
updatePost(post: {
id: "001"
title: "My updated post!"
}) {
id
title
}
}
mutation deletePost {
deletePost(postId: "001")
}
```
