This Serverless plugin provides a fast iterate -> test loop in your CLI.

Logs delivered from CloudWatch to your terminal.

watch-glob

Customize the path or paths (comma-separated) to watch. Supports glob/regex, or a direct file. Useful if you have a large project but only want to redeploy if one (or a few) files change. Also useful if my regex is missing a file you use.

Usage

sls run-watch --function <your function name>

This plugin grew from a hacky script which combines two commands built into the framework: serverless logs and serverless deploy function, along with chokidar, a library based on fs events.

It is useful only when changing function code, or function configuration changes like architecture, timeout, memory, or environment variables. Other changes (adding new functions, adding IAM permissions, new events, or provisioning additional resources) requires a full CloudFormation deployment.
