CDK Watch

See original GitHub issue

Description

CDK Watch is a new feature of the AWS CDK which allows developers to quickly iterate on development stacks. CDK Watch performs quick updates to AWS Lambda function code and ECS images in response to changes in the application code. CDK Watch has an extensible design, which means that it will be possible to support additional AWS resources such as API Gateway models, Step Function workflows, and more.

@eladb @skinny85 can the newly released CloudFormation feature to keep failed stack deployments abd retry/update them be useful for this capability in addition to API-based updates? https://aws.amazon.com/blogs/aws/new-for-aws-cloudformation-quickly-retry-stack-operations-from-the-point-of-failure/

Yes. This was already implemented in https://github.com/aws/aws-cdk/pull/16293 as a switch in the cdk CLI, and will be turned on by default for deployments done with the --hotswap option (PR in flight: https://github.com/aws/aws-cdk/pull/15748).

In case you are looking for this feature, I’ve created a wee lib to make this possible: https://github.com/teamplanes/cdk-watch

We are using it on a few projects and it has sped up developer workflows/feedback-loops dramatically.
