Serverless Offline Plugin to Support Step Functions for Local Development.
Features:
- Fully Written in TypeScript
- Promise based (no process spawn)
- Completely based on AWS Docs
If the plugin is being useful in your company and/or project and want to keep the development active, consider buying me a coffee 🙂... coffee is the thing that makes me the most happy person in the world and I'd appreciate the sponsorship.

- serverless
- serverless-offline
- serverless-step-functions plugin
- serverless-webpack (optional)
``shell
$ npm i -D @fernthedev/serverless-offline-step-functions
$ yarn add -D @fernthedev/serverless-offline-step-functions
`
The plugin contain a couple of options to configure in custom
`yml`
custom:
'@fernthedev/serverless-offline-step-functions':
port: 8014
enabled: true
debug: false
- port: Port of the Step Functions API Simulator (Default: 8014)enabled
- : Enabled Step Function API Simulator (Default: true)debug
- : Enable Debugger Output (Default: false)
If your project uses serverless-webpack to compile/transpile your serverless application. Make sure is defined in your plugins before this plugin and serverless-offline
`yml`
plugins:
- serverless-webpack # Defined Before

- The library will only start with $npx sls offline start and not npx sls offline.
