This simple utility allows you to edit a Lambda function from your local machine and upload code changes directly to AWS using a file watcher.
The first thing it does is download, and unzip the source code locally, then it watches for file changes. When a file change occurs, it zips up the folder, uploads the zip file to an S3 bucket, and updates the Lambda function.
The function is downloaded to the current folder as <function-name>.zip and unzipped to a folder called <function-name>. The function is also uploaded to S3 as s3://<bucket-name>/<function-name>.zip.
Installation:
npm install -g dnewmon/lamda-watcher
Usage command:
lambda-watch --s3-bucket=<bucket> --function-name=<function> \
[--aws-region=<region>] [--aws-profile=<name>] [--change-delay=5]
[--revision-id=$LATEST]
--change-delay is the number of seconds to wait before deploying a change. This reduces unnessasary updates.
--revision-id allows you to specify a version of the function to update. Typically $LATEST can be used to
update just the latest version of the function.
