Hey there, thanks for creating SST which is awesome! I’m trying to work out how AWS CDK works together with SST and just found that

sst start

command not watching the code changes anymore if the code located under

src/notes

folder. Initially followed the graphql-appsync example which was working fine. Just wondering whether SST supports that? Or maybe something wrong with my setup? Thanks

Here’s the code for integrating CDK with SST

Copy code

```
import * as sst from "@serverless-stack/resources";
import * as appsync from '@aws-cdk/aws-appsync';
import * as lambda from '@aws-cdk/aws-lambda';
import * as db from '@aws-cdk/aws-dynamodb';
export class AppsyncSstStack extends sst.Stack {
  constructor(scope: <http://sst.App|sst.App>, id: string, props?: sst.StackProps) {
    super(scope, id, props);

    const api = new appsync.GraphqlApi(this, `${scope.stage}-AppSyncApi`, {
      name: `${scope.stage}-AppSyncApi`,
      schema: appsync.Schema.fromAsset('graphql/schema.graphql'),
    })

    const noteTable = new db.Table(this, 'Notes', {
      partitionKey: { name: 'id', type: db.AttributeType.STRING },
    })

    const notesQueryHandler = new lambda.Function(this, 'QueryDataHandler', {
      runtime: lambda.Runtime.NODEJS_14_X,
      code: lambda.Code.fromAsset('src/notes'),
      handler: 'index.handler',
      environment: {
        NOTES_TABLE: noteTable.tableName,
      },
    })
    noteTable.grantFullAccess(notesQueryHandler)

    const notesDataSource = api.addLambdaDataSource("notesDataSrouce", notesQueryHandler);
    notesDataSource.createResolver({
      typeName: 'Query',
      fieldName: 'getNoteById'
    })
  }
}
```

From

sst-debug.log

, with above code, the code under

src/notes

doesn’t seem to be watched. Well for the graphql-appsync example code, can see

lambda-watcher-state

in the log with

"entryPointsData":{"./src/notes/main.handler"

looks like code watch only works for sst lambda, but not for cdk?

@Frank can I get some help please? Thanks 😊

Hey @Longyang Zhang, yeah live debugging only works with

sst.Function

. You can try defining your Lambda function above like this:

Copy code

const notesQueryHandler = new sst.Function(this, 'QueryDataHandler', {
      runtime: lambda.Runtime.NODEJS_14_X,
      handler: 'src/notes/index.handler',
      environment: {
        NOTES_TABLE: noteTable.tableName,
      },
    })
