ūüõ† stepfunctions-localhost

A wrapper for AWS's Step Functions Local.

Heavily inspired by dynamodb-localhost.

Requirements

  • Java Runtime Engine (JRE) version 6.x or newer

Install

npm install stepfunctions-localhost

Usage

const StepFunctionsLocal = require('stepfunctions-localhost');
 
const stepfunctionsLocal = new StepFunctionsLocal();
 
(async () => {
  await stepfunctionsLocal.install();
 
  stepfunctionsLocal.start({}).on('data', data => console.log(data.toString()));
 
  setTimeout(() => {
    stepfunctionsLocal.stop();
 
    stepfunctionsLocal.remove();
  }, 5000);
})();

This will download the files required to run step functions, start the step function server, wait 5 seconds, then stop the server and clean up after itself.

API

new StepFunctionsLocal(options)

Creates a new instance. options defaults to {quiet = false, path = './.step-functions-local'}.

.install()

Downloads files required to run step functions. Path defaults to ./.step-functions-local.

Returns Promise.

.start(options)

Starts the local server. Options match those of the actual step function server:
